I can basically not see the accumulation of cyanobacteria

I can't smell it

The eye -catching view is

The vast water and the sky

last year

For the first time in Chaohu, a large -scale cyanobacteria water time

It was postponed 56 days from the previous year

As of July 8 this year

There is no obvious cyanobacteria water, which has been postponed 37 days compared to last year

Significant results in the prevention and control of cyanobacteria

The 57 -year -old Meng Xuesong has been dealing with the cyanobacteria in the lake area since 2019, and witnessed the changes in Chaohu Lake in the Lake Lake. "At this time in previous years, our deep well equipment was operating 24 hours. This year, there is basically no cyanobacteria, and the water quality of Chaohu is getting better and better!"

"We‘ smell ’to reach the gratifying changes in the water quality of Chaohu Lake!”

"Home in Binhu, the staff who did not smell the odor, the staff who controlled the cyanosais worked hard!"

"Recently, I went to Chaohu Lake to play around, and there was no odor!"

"The effect of a year is obvious than the year!" ... the majority of netizens praised.

Chaohu cyanoscopy is less a year than a year

On the morning of July 6, Meng Xuelong and several colleagues were on duty on the algae control platform of Bingzihe No. 1.

This platform consists of deep submarine high -voltage algae control equipment, lifting operation platforms, high -efficiency and adjustable vortex wells, steel structure walkways, and water -filled cyanobacteria diversion fences and other equipment. Meter.

At the scene, accompanied by the roar of the machine, a large amount of water in the Chaohu Lake was poured into a deep well with the pressure. "This well reaches 78 meters, and the inhaled cyanoblagic airbag structure produces 0.5-0.7MPa to make it collapse, and the cyanobacteria cells cannot float and sink the bottom. Simply put, it is to make them deep into the lake. After decomposition, it was purified by water biology. "Zhang Congjin, deputy director of the Baohe District Ecological Environment Branch.

Looking at the vast lake, Meng Xuelong was excited. Lao Meng was a fisherman of the Chaohu Lake before, and now he guards Chaohu every day, and has obvious results and proud. "You see! Now the lake is basically not seen, there is no odor! At present, our workload is much lighter than last year. From 7 am on the morning to 7 pm, it was basically 24 hours in the past. Benefit. We will not slack, and we will stick to their posts every day. "

Nowadays, in Baohe District, four deep well -voltage algae control platforms have been built, all of which are put into operation, and the daily processing capacity has reached 386,400 cubic meters.

The Tangxi River Acetic separation station, which is not far from Bingzi River No. 1, is much quieter compared to the same period of previous years. Entering the separation station workshop, the workers are also on duty, but the equipment at the scene did not work.

"Algae water with more than 20 salvage platforms along the lake will enter our separation station. For cyanosal, we insist on finding that it is fishing. Nissan is clear in the past two days. The station director Wang Chunnian said that the separation station mainly treats the cyanobacteria through separation and dehydration process.

Wang Chunnian, who lives in Binhu Runyuan, lamented that Chaohu Lake Basilus was less than year year after year, and the governance had achieved remarkable results. "In 2019, we dealt with more than 10,000 tons, and dealt with more than 6,000 tons in 2021. Only dozens of tons have been processed so far this year." Wang Chunnian said that because of the taste of cyanobacteria, the residents of the community did not even dare to open doors and windows at home at home. Essence "Now there is basically no odor! Many people go to the lake park to take a walk and take a walk. I feel happy!"

Divide the grid responsibility to the daily production of people to produce

Candida prevention and control is a major livelihood project. Since the beginning of this year, the city has strengthened the prevention and control system of "territorial management, hierarchical responsibility, scientific early warning, timely response, departmental linkage, and social participation", improve the ability of Chaohu Candal Calcocarius, and resolutely fight against the battle against blue algae prevention and control.

"As early as March of this year, the city was scheduled in advance, requiring various departments and departments to further implement responsibilities, refine measures, and match personnel, facilities, and equipment, and make a good job of adding, maintenance, and maintenance of various types of salvage facilities and equipment in advance. From April 1st, the emergency prevention and control of cyanoids was officially launched. "The relevant person in charge of the Municipal Ecological and Environment Bureau said.

It is understood that the city has established a three -level grid -based prevention and controlling and salvage responsibility system. The city divides a total of 5 first -level grids, 18 second -level grids, and 65 3 -level grids. The scope of prevention and control, key prevention and control areas, salvage personnel and salvage disposal facilities and equipment. Establish a municipal inspection and supervision mechanism, and the three municipal -level inspection teams regularly carry out on -site inspections on the prevention and control of cyanobacteria.

At present, the city has basically constructed the nest of the cyan lake cyanobacteria water Chinese emergency response facilities based on the cyanosaurus processing device and the algae separation station. "Huanhu has built 5 algae water separation stations, 44 salvage platforms, 7 deep well processing devices, and more than 400 algae control facilities such as cyanobacteria magnetic catcher, 146 other types of salvaging vessels, and flowers. , Corporation of algae block (coffee) more than 90 kilometers, "said the relevant person in charge of the Municipal Ecological and Environment Bureau.

Continue comprehensive management of Chaohu Lake Water Quality Stability

Candal governance is a worldwide problem. The achievement of staged results is inseparable from the comprehensive governance of Chaohu.

In recent years, the city has adhered to systematic governance, scientific governance, and governance according to law, and comprehensively implemented the "five major projects", the source of the line source, the sources of the line, the internal source of the "four sources" of the "five major projects", the ecological restoration, the green development, the green development, and the people. "Let Chaohu the best business card for Hefei."

"Since the comprehensive governance of Chaohu in 2012, it has completed a total of more than 40 billion yuan, of which more than 13 billion yuan has been completed since August 2020," said the relevant person in charge of the Provincial Nest Management Bureau.

According to the feedback data of the Ministry of Ecology and Environment, from January to May this year, the average quality of water quality of Chaohu East, West Lake, and Quanhu was category IV. Compared with the same period in 2021, the main phosphorus of the main pollutants of Chaohu East, West Lake and the whole lake of the lake The year -on -year decrease of 11.9%, 18.2%, and 14.7%, respectively.

"In addition to the natural factors such as climate, the reduction of nest lake cyanobacteria is inseparable from the strong governance of the local government." Said Shi Xiaoli, a researcher at the Nanjing Geography and Lake Research Institute of the Chinese Academy of Sciences.

Far conspiracy and governance, symptoms and symptoms, accelerate the process, and work for a long time. At present, Hefei is strongly, orderly and effectively to promote the "five major projects" and "four sources", and achieve three types of water in the whole lake as soon as possible. Citizens will see greater changes and greater changes.

What are the facilities, methods and technologies of cyanobacteria governance?

Today we will introduce some.

First take a look

In previous years, when the large -scale gathering of cyanobacteria, the algae water separation station opened the "green algae" mode, collects and salvage the lake surface, transported to the separation station through the pipeline, and then the bun cluster was broken and settled. And remove algae water.

The algae residue is dehydrated, forming the algae mud with a moisture content of 85%-90%. The algae mud is transported to the use of third-party resource utilization. Essence

According to Linhe Town, the head of Feidong County

Song Xiaofei, Director of the Environmental Protection Office

Since summer this year

The area has not formed a large -scale gathering of cyanobacteria

As of the end of June

Only 21 tons of algae mud are produced

The same period last year was 126.6 tons

Come again

A product that can automatically find cyanobacteria killing

And a cyanobacteria monitoring equipment

On the morning of July 6, the pilot pilot pilot pilot of the China Environmental Valley Water Environment Hospital was launched in Blackchi Basket, Shushan District.

On the morning of the same day, the staff sprinkled white granular governance products to the water. White substances gradually spread with the water waves, and soon covered the coastal water surface. "The emphasis on the governance of cyanobacteria is to prevent it." Wang Pu, general manager of the Green Environment Greater China, said that the governance product is a slow -release -release type that can float on the water and automatically find the cyanobacteria to kill. The effect can last for more than a month.

Subsequently, the personnel of third -party testing agencies extracted water samples from time to time to detect the effects of water governance and the safety of products through the real -time monitoring equipment.

It is understood that the cyanobacteria monitoring equipment was developed by the Institute of Material Science of the Chinese Academy of Sciences. "In the process of water governance, governance is the end means, and the front end is monitoring." Yin Gaofang, a doctorate instructor at the research institute, said that the equipment can monitor the algae chlorophyll content, algae activity (growth, explosion period, decline period), etc. Parameters to form a trend of water quality and provide comprehensive diagnosis information; at the same time, in real time tracking the effect of governance, mastering the governance's algae state and changes.

The pilot was carried out by Hefei Zhongke Environmental Monitoring Technology National Engineering Laboratory Co., Ltd. Among them, the cyanobacteria monitoring equipment of the Institute of Material Sciences of the Chinese Academy of Sciences conducts a 24 -hour non -intermittent monitoring of the pilot water body. New model of online monitoring+governance ".

Zhang Xiang, the person in charge of the China Science and Technology Environment Project, said that through the pilot mode of "online monitoring+governance", the big data of cyanobacteria governance can be formed to provide data support for the effective prevention and control of cyanobacteria, accurate governance, and the study cycle research and water body governance of water body governance.EssenceText | Ji Yungang All Media Reporter Hua Xinhong Guo Ruqi Su Longpeng
