Nanchang builds an ecological front lake with "rivers, clear water, shore green, and beautiful scenery"

Nanchang Evening News · Ai Nanchang client (Shi Chunlai reporter Wu Yueqiangwen Wanwen Wanyi Ma Yue Figure) On July 29, Nanchang City held a press conference on the governance work of the Qianhu Water Series. The relevant situation of the governance of the former lake system was notified.

Luo Jianhua, director of Nanchang Urban Management and Comprehensive Law Enforcement Bureau, introduced that Qianhu Water Series is an important part of the water system of the "One River and Ten River" in Nanchang. Square kilometers. Taking the Lotus Road and Ruijin Road as the boundary, the Qianhu water system is divided into three parts: dam, in the dam, and under the dam. Among them, the parts of the dam are South China water canal and Yunxi water canal, which are the water system upstream of the Qianhu Lake; the lower part of the dam is Qingyuan canal and Red Kok landscape canal. The dam is the Qianhu Reservoir with an area of ​​about 2500 acres.

In recent years, with the rapid development of our city's economy and society, the former lake system and surrounding areas have become an important sector for the rise of the new city. The permanent population has increased from less than 170,000 in 2012 to more than 450,000. Daily sewage rose from 56,000 tons to more than 157,000 tons. Due to the units and communities that have not been implemented in the early construction, some units and communities that have been implemented in the diversion of rain and sewage have been implemented. Body water deterioration. At the same time, there are many development and construction plots around the Huihui Water Area, and there are a small amount of sewage direct discharge and construction yellow mud water sneaky, which makes the water body of the Qianhu Reservoir turbid and low transparency, and it is difficult to survive in water. Ecological chain has deteriorated the water ecological environment. Previously, the city has adopted local pollution interception tube, water diversion activation, and ecological governance, but the results are not obvious, and the problem has not been fundamentally curbed. Under extreme cases, the former lake system even had darkness and odor, which once became an annoyance of surrounding residents.

The annoyance of the masses is the government's heart. Earlier this year, the Nanchang Municipal Party Committee and Municipal Government made up their minds to point out the sense of gain, comfort, and happiness of the masses, completely solve the prominent problems of the former lake system, and create an ecological before the ecology of "smooth river, clear water, shore green, and beautiful scenery". lake. The main leaders of the Municipal Party Committee and Municipal Government went to the Qianhu Water Department for investigation many times, clarifying the governance goals of "seeing the results at the beginning of three months, achieved significant results in half a year, and seeking results within one year". System governance schemes such as covering green, ecological repair, water body activation, construction control and control.

Through the special rectification of half a year, the quality of the water system in the former lake was significantly improved, the water environment was significantly improved, and the water ecology continued to improve. Compared with December last year, the ammonia nitrogen concentration of lake pollutants was reduced by 18%in June this year. The water quality of Qianhu Lake was maintained above the V class to stabilize the requirements of the general landscape water quality; New places for tourism and sightseeing.

Specific measures in the early rectification are summarized in the six words- "clearing, interception, protection, living, passing, and patrol".

"Qing" means dredging and dredging. At present, the South China canal, Yunxi Water System, Red Korn Water System, Qingyuan canal bottom mud dredging work, which is about 10.3 kilometers; The section of the canal is implemented with the bottom of the slice stones and pebbles to reduce the stirring of the water and the flow of the mud.

"Decepness" is the sewage interception tube. The Yunxi Water System and South China canal water system on the upper reaches of Qianhu Lake carried out a network investigation along the line. A total of 54 problems were detected, and all measures such as interception tubes were rectified. According to the results of the water quality encryption monitoring of the ecological environment, the chemical oxygen demand, ammonia, and total phosphorus of Yunxi's canals decreased by 49.3%, 26.2%, and 58.1%, respectively; The main pollutant ammonia nitrogen decreased by 78.5%, which effectively solved the problem of sewage direct drainage canal from the source.

"Protect" the slope covering green. The naked loess, vegetable land rectification and slope covering work along the water system have been fully carried out. It has completed the surrounding shore slopes of about 230,000 square meters, planting more than 11,600 seedlings, about 2.15 million aquatic plants and sinking water plants The remaining plants, cleaning up about 140,000 square meters of illegal vegetable fields, effectively reducing the impact of yellow mud water on the Qianhu water system.

"Live" is the activation of water diversion. Since mid -to -late November last year, about 170,000 cubic meters of live water is introduced from the Ganjiang River every day to supplement the Qianhu Lake, especially the water bodies of the edge corner area are activated by installing the live water pump. Improve the liquidity of the former lake. Supplement and improve the former lake biological chain, put more than 100,000 pounds of grass fish, catfish, snails, etc. from Qianhu, further enriching the Qianhu ecological chain system and improved the purification ability of Qianhu Water.

"Tong" is the water system Unicom. Maintain the sluice along the Qianhu Water Series. By closing the China Southern Airlines gate, it blocks 1.8 meters of culverts in Qianhu Avenue, lifts up the water level of the high -definition canal, opens the old street gate, and opens the Qianhu water system to further activate the downstream canal.

"Tour" is law enforcement inspection. While adhering to the governance of the water environment, the enforcement inspections of the former lake system have been comprehensively strengthened, especially for key supervision inspections on construction sites and key drainage households, severely cracking down on illegal drainage and pollution, and timely elimination of hidden dangers of water pollution. In the past six months, a total of more than 300 law enforcement officers were dispatched to inspect more than 180 inspections on various construction sites around the former lake system, and more than 1,200 inspections were conducted on 600 drainage households including surrounding restaurants, hotels, hotels, enterprises and institutions, and investigated and punished for investigation and punishment. 15 households with a penalty of more than 800,000 yuan. Among them, the top of the top was punished, and the illegal sewage discharge of 300,000 yuan was punished for illegal sewage in a certain construction site in Honggu Beach. In the next step, Nanchang City will continue to grasp the governance of the Qianhu Water system to ensure that the goal of "quantity change to qualitative change" and "great results in one year" of the former lake system will be achieved.

Adhere to the governance of the whole basin system. Establish a systematic thinking, comprehensively rectify upstream, downstream, left and right shores, and dry tributaries, comprehensively improve the water quality of the former lake, and form an organic ecosystem of natural flow of water.

Strengthen the source of pollution. Combined with the three -year tackling operation of the water environmental governance of our city, the rain and sewage pipe network surrounding the surrounding area of ​​the lake system has been carried out, and the rain and sewage pipes surrounding areas are wrong, omissions, and mixed rectifications to completely solve the problem of sewage overflow of sewage pipes from external water.

Persist in strict long -term management. Establish a daily inspection and supervision mechanism, strengthen the inspection of the coastline, and do everything to be collected and changes to the problems discovered. At the same time, increase regulatory and law enforcement, and "zero tolerance" on violations of pollution discharge.

Construct a co -governance sharing pattern. Strengthen publicity and guidance, extensively mobilize the citizens to participate in the governance of the former lake and water system, listen to the opinions and suggestions of the masses carefully, deal with the issues reflected immediately, and respond in a timely manner.
