Special reporter Ye Xiangcheng

In July of this year, Shiyan City, Hubei Province, was included in 28 broken noodles of the city's cross -border water environment quality assessment. 27 reached the requirements of the assessment goals, and the monthly standard rate was 96.4%; The 116 broken surface reached the assessment target, with a monthly standard rate of 97.5%; the number of days of excellent environmental air quality in the urban area was 31 days, and the standard rate was 100%...

The Municipal Ecological and Environment Bureau has always insisted on grasping the team and leading the team to create an ecological environmental protection iron army that can endure hardships, fighting, and listening to orders. Over the years, this iron army has promoted the continuous improvement of the environmental quality of Shiyan through scientific water treatment, accurate gas treatment, specialized soil treatment, and intelligent supervision. Due to outstanding work performance, the Municipal Ecological and Environment Bureau was recently named and commended by the Party Central Committee and the State Council.

Scientific water governance

"A certain water quality in the lower reaches of the Shending River appears abnormal, please come and deal with it!" One afternoon, the city of Shendinghe River suddenly received a call from the masses. Five staff members heard the order and drove quickly. They arrived in 5 minutes and arrived in 5 minutes. on site. After the field inspection and treatment, the water quality returned to a clear state in half an hour.

The Shending River is the first -level tributary of the Hanjiang River. It originated from Laoshi Longyu, Dachuan Town, Maojian District. It was remitted into the Hanjiang River in Chadian Town, Liyang District. The total length was 58.1 kilometers. The basin area was 227 square kilometers. The Shending River Basin is the largest population gathering area of ​​Shiyan. The population in the basin is more than 700,000, accounting for nearly 80%of the total population in the urban area.

Due to historical reasons, before 2012, the water quality pollution of Shending River was extremely serious. The internationally universal high -difficult governance of the river is 1: 5, while the dirt ratio of the Shending River reaches 1.5: 1, which is very difficult to govern. In recent years, the city has invested more than 3 billion yuan, adopting measures such as sewage interception, clearing, pollution control, pollution reduction, pollution control, and pollution of pollution to control the Ding River. After years of system management, in 2019, the water quality of the Shending River has undergone qualitative changes, eliminating the inferior V class to reach Class V.

In order to continue to consolidate the results of the Dinghe River, in April 2020, the city of Shendinghe River in the city was established in the Shendinghe sewage treatment plant, which clarified the two -level river chiefs in the urban area. long.

"Our long -term office has personnel, vehicles, work systems, office places, and funding guarantee." Lan Jinsong, Secretary of the Party Group and Director of the Municipal Bureau of Ecology and Environment, said that the city has arranged work funding and from the city's ecological environment The key units such as the bureau, the Municipal Housing and Urban Construction Bureau, and the Municipal South Water and North Diversion Water Source District Protection Center will transfer 5 elite soldiers to the Hechang Office for centralized office.

The Hecting Office has a comprehensive group and engineering group. The comprehensive group is mainly responsible for daily overall coordination, scheduling notification, governance technical analysis, dispatching of pollution control facilities, and supervision of governance tasks. Implementation of engineering projects, coordinating the processing of the project, promoting the implementation of projects, inspecting the quality of the project, organizing and coordinating project acceptance and supervision.

According to the relevant staff of the Shendinghe River's office, Shiyan sets the Shending River Chang Office in the sewage treatment plant, and is located at the forefront of the governance of Shendinghe. Water quality is stable.

In recent years, the front -line office of the city of Shendinghe River has strongly guaranteed the continuous improvement of the water quality of the Shending River. In 2020 and 2021, the average water quality of the Shendinghekou section reached Class IV for two consecutive years.

This year, the city formulated and introduced the water quality IV of the Shendinghe River Basin to enter the III category. It plans to invest 2.4 billion yuan to further carry out the sewage tube of the water and the sewage treatment, the management and control of the sources of industrial pollution, and the inner source river flow. Six major projects, including ecological restoration, agricultural and rural pollution, and water source dispatch. By 2025, the comprehensive water comprehensive standard rate of the surface of the Shendinghekou section on the surface of the section of the Shendinghekou was increased to 80%.

The Water Quality IV IV of the Shending River Basin enters the technical solution of Class III, and will implement 33 projects in two phases. Among them, from 2022 to 2023, focusing on the implementation of sewage and diversion, the expansion of the sewage treatment plant in the basin, the deep nitrogen removal and phosphorus removal demonstration of the tailwater of the sewage treatment plant, the wet wet water drainage and sewage dispatching system construction system. Realize the target of 80%comprehensive standard rate at the surface III water category III water. From 2024 to 2025, it will focus on the second phase project of the tail water deepening nitrogen dehydration of the sewage treatment plant and the dirt -clear diversion project of Yonggou area, and implement 10 projects such as smart drainage and water to stabilize the section III category of the section of the Dinghekoukou. 80%of the target of 80%comprehensive standard.

Accurate qi

"Dongfeng Company's body plant was relocated to the land organizational project, and the road was dry and dusty on the field ..." At about 3 pm the day ago, the third -party inspection WeChat group received a message from Shiyan City. Together with this information, there are two reflection of the current map of dust pollution and a Tencent map positioning information.

After seeing the information, Wen Chengjun, the relevant person in charge of the Dongcheng Economic Development Zone of Maojian District, immediately arranged for a special person to deal with it. Less than 2 hours, the road dust problem was solved.

"Over the years, we have been using embroidery kung fu to control atmospheric pollution." Feng Youjun, head of the atmospheric department of the Municipal Ecological and Environment Bureau, said, "From the second half of 2018, we hired third -party institutions to conduct air pollution prevention and control on the spot. Find the problem in time. Seven days a week, 6 white classes, one night shift, 365 days a year, the wind and rain are unimpeded. The inspection area is Zhangwan District, Maojian District, Shiyan Economic and Technological Development Zone, and Chengguan Town, Puyang District. The drive is as high as 100 kilometers. "According to reports, the inspection content mainly includes the prevention and control of the dust pollution of the construction site, and the transport vehicles such as the dusk and the concrete mixer car are on the road and the ruling along the way. Motor vehicles have black smoke. They immediately took pictures and obtained evidence and sent them to the third -party inspection WeChat group in Shiyan City in a timely manner.

Regarding the problems of individual overlap and the effectiveness of rectification, they also promoted the solution by holding the on -site meeting.

In order to deal with problems in a timely manner and facilitate feedback to rectify, the city's atmosphere of third -party inspections of the atmosphere carried out the WeChat group in the third -party inspection of Shiyan atmosphere. The heads of the districts and townships and streets, the person in charge of the relevant departments, and the person in charge of the dust pollution prevention work of key construction sites have joined the group. At present, the group has reached 299.

Beginning in January 2019, the city has also evaluated the air quality of the township towns and towns and towns and towns in the central urban area. Reward the ranking of the assessment rankings will be notified and criticized.

In order to realize the "grid" supervision of the quality of the air environment, the city has invested more than 5 million yuan to set up 159 air micro -stations in the central urban areas and the county (city, district) closer to the central urban area. Feng Youjun said that they are equivalent to air "film police" and supervise the quality of the air environment within 1 kilometer. If air pollution appears around, the "film police" in the jurisdiction will be perceived for the first time with its keen "smell" and "alarm" to the air monitoring platform in order to investigate and deal with it in a timely manner.

The city also invested nearly 1.5 million yuan, purchased 30 sets of dust pollution online regulatory facilities, and installed on the construction site, which can monitor 7 parameters such as the quality of the air environment on the weather. The monitoring results are scrolled by the display screen.

The facility is fixed by a 3 -meter stent and has the characteristics of convenient installation and disassembly. After a construction site is completed, it can be quickly transferred to other construction sites. Video surveillance probes and audio facilities are also installed near the facility, which cooperate with dust pollution online regulatory facilities to implement remote supervision on the construction site. Once the monitoring data exceeds the standard, the air quality at the construction site can be found through the remote video probe, and the constructor can be remotely called through the audio facilities remotely, and the construction party promptly correct the dust pollution behavior and quickly reduce the dust pollution of the construction site.

On this basis, our city also supervised 54 industrial enterprises to implement corporate environmental protection responsibilities and carried out volatile organic governance. Road pollution prevention and control, complete the installation of the online monitoring equipment of oil and gas recovery of 5 gas stations and 5109 non -road mobile machinery registration cards.

Through efforts, the quality of the air environment in our city has continued to improve. In 2021, the cumulative number of days in the urban area reached 337 days, the standard rate was 92.3%, the average concentration of PM10 was 52 micrograms per cubic meter. The best conditions.

Professionalism

The clear water flows into the pool made of pebbles, dozens of fish are swimming in the pool ... Recently, in the Wudang Mountain Special Economic Zone Wudang Mountain Street, Yuanhe Guancun Temporary Swing Water Treatment Station, the Municipal Ecological Environment Bureau Wudang Mountain Branch Director Yao Wanjun pointed to a box -type sewage treatment facility and said that the facility uses a CBC process to allow the water to reach the first -level A standard, which can be used as a mixed use of water.

In recent years, the city has actively strived for approximately 1.2 billion yuan. In 10 counties (cities, districts), a comprehensive remediation of rural environment in administrative villages in 10 counties (cities, districts) has been comprehensively rectified. The coverage rate of administrative villages has reached 87.5%. The renovation content focuses on domestic sewage, domestic garbage, etc.

During the rectification, there were about 300,000 trash cans in our city, about 10,000 transitions in the garbage, and more than 2,000 garbage collection vehicles; 550 courtyard sewage treatment facilities, 1527 centralized sewage treatment facilities, and integrated water and fertilizer in one. There are 507 facilities, and 1550 kilometers are supported by the construction of a sewage collection pipe network.

In order to prevent rural sewage treatment facilities from "sun -sun", our city held many meetings to improve the long -term operating mechanism of rural sewage treatment facilities. All counties (cities, districts) should choose 1 or 2 processes according to local conditions, and clearly explicitly operate during the 3 to 5 years, and the construction unit provides free operational services. After the free operation period, the counties (cities, districts) have selected enterprises with strength, technology, and experience through bidding and other methods to specialize in operating and maintenance of rural sewage treatment facilities. The operating costs are responsible for the government.

"Let the professionals do professional things." The relevant person in charge of the Municipal Agricultural Governance Office introduced that except for the sewage treatment plant under the jurisdiction of Shiyan Economic and Technological Development Zone, other counties (cities, districts) have adopted government purchase services Methods to implement third -party professional operation and maintenance of rural domestic sewage facilities. In order to promote the standardization of rural sewage treatment facilities, the city has formulated the rules for the management of rural sewage treatment facilities for operation and maintenance management. This detail includes assessment items such as operation and maintenance management, professional operation and maintenance, facility operation, and clarify the management system, assessment supervision, supervision monitoring, operation and maintenance capacity, operation and maintenance files, stations, sewage pipe networks, terminal facilities, water quality standards for standards for standards for standards Wait.

"Sewage treatment facilities greater than 100t/d (including), monitor once a quarter; sewage treatment facilities with a scale of 20T/d (inclusive) -100T/d, monitor once every six months; scale is 5T/d (including including 5t/d (including ) -20T/D sewage treatment facilities, monitor at least once a year ... "The person in charge of the Municipal Agricultural Governance Office introduced that the establishment of the operation and maintenance management system for rural sewage treatment facilities was established, which provided a strong guarantee for the city's" beautiful countryside "construction.

Over the years, the city has adhered to the construction of the national ecological civilization construction demonstration city and the "two mountains" practice innovation base construction as the starting point, and continuously improved the level of ecological civilization construction. The city created 148 ecological towns and 1610 ecological villages, and all 8 counties (cities, districts) all created a provincial -level ecological civilization construction demonstration county (city, district), and the number and quality of the province were created. In Hubei Province, we have taken the lead in creating a demonstration city in the national ecological civilization construction demonstration city and the national "green water and green mountains are Jinshan Yinshan" practice and innovation base.

Intelligent supervision

Once, residents of a community in the urban area burned the branches, and the city environmental emergency and accident survey center locked the specific location of the fire point through a video probe, and immediately sent someone to deal with it. This is the epitome of the city's smart environmental protection regulatory system.

Shiyan is an old industrial base. It used to pollute the source point and long -line, while the environmental supervision capacity was insufficient, and law enforcement officers were very hard. If individual enterprises have sneaked sewage during the holidays or heavy rain, even if law enforcement officers are squatting day and night, it is often difficult to catch. However, Shiyan is the core water source area of ​​an important ecological functional area in the country and the central line of the South -to -North Water Diversion Middle Line. It is a sacred mission to protect the ecological and one -library water water.

How to improve the effectiveness of environmental supervision, solve problems such as few environmental supervision and regulatory personnel, and wide supervision? Lan Jinsong said that our city has successfully created smart environmental protection projects in order to better serve environmental management and environmental law enforcement.

The total investment of smart environmental protection projects in our city is 50 million yuan. Using the Internet, big data, artificial intelligence and other technologies to integrate 1237 sets of environmental quality and automatic surveillance facilities of pollution sources, and achieve full coverage of environmental protection and supervision. The key construction sub -projects include a data center, two major perception systems, three gateway websites and six application systems.

Where is the wisdom and environmental protection wisdom? The staff of the bureau introduced that smart and environmental protection can capture abnormal data and automatically dispatch law enforcement officers on -site law enforcement; can monitor environmental violations and lock relevant evidence; can analyze data through the background to provide reference for leadership decisions.

The data center, known as the smart and environmentally friendly brain, has currently included information covering various environmental factors such as water, gas, and noise. The two major perception systems are online monitoring systems and video surveillance systems. Among them, the online monitoring system installed 189 units of pollution sources online monitoring equipment and 212 sets of environmental quality monitoring equipment; a total of 379 high -definition cameras were installed in the video surveillance system. Essence

The three gateway websites include internal networks, external networks, and mobile portals. Among them, the internal network is a special network for Shiyan Smart Environmental Protection Office. The outer network is the official website of Shiyan Environmental Protection Bureau. Using the internal network, external network, and mobile network, you can achieve the sharing of environmental protection information of Shiyan well.

Shiyan Environmental Mobile APP will publicize air quality, water environmental quality, and 189 enterprise monitoring data for the installation of online monitoring devices to be disclosed in the mobile app to facilitate public supervision.

The six major application systems are Shiyan Smart and Environmental Protection of the Six Skynet, which are air quality monitoring network, water environmental quality monitoring network, noise monitoring network, key industrial pollution source monitoring network, hazardous waste monitoring network, and motor vehicle exhaust gas monitoring network.

Speaking of these six sky networks, the director of the Municipal Environmental Emergency and Accident Investigation Center, such as several Treasures: Air Quality Monitoring Network can currently check the monitoring data of the city's 17 air monitoring stations at any time. Water Environment Quality Monitoring Network can check monitoring data of 19 water quality stations, 17 drinking water sources, and 35 water quality monitoring sections in the city at any time. When the automatic station data appears abnormal, you can check the surrounding environment through video probes, lock up related evidence, etc. The noise monitoring network currently installs 10 sets of noise monitoring equipment to achieve real -time regional environmental noise supervision. Dangerous waste monitoring network realizes the full monitoring and management of hazardous waste "from cradle to grave". The motor vehicle exhaust gas monitoring network has now achieved all -round monitoring of 17 motorcycle environmental protection monitoring agencies and 39 monitoring lines in the city, which can prevent false behavior.
