Today is different, and 22 water bodies are no longer “black and smelly”
As the head office of the management of black and smelly water bodies, the Xiangtan Municipal Housing and Urban-Rural Development Bureau recently released a news report: As of now, among the 24 black and smelly water bodies in the city, the Jingguang Canal and the Fengshou Canal have completed the rectification tasks, and the rectification consequences are being evaluated; Yijia Lake<a 20 water bodies including the Nanyang Canal, Yangtang Canal, War Park, Yuhu Lake Pond, Weitan River First-level Canal, Weitan River Second-level Canal, Songzhang Canal, etc. have achieved the goal of eliminating black and odor, and the initial results are expected to be achieved; the Jianglu West Canal and Jili Canal, which are still under construction, will no longer be "black and odor".
At the beginning of this year, in the province’s report on the real efforts and obvious results of 2017, Xiangtan City’s black and smelly water management light gift was on the list, and received 2.5 million yuan in bonuses for the first time, and received a high degree of confirmation of the central environmental protection inspection team and the provincial housing and construction hall.
Escort barriers to organization, survey, construction and inspection will not be as small as
Article, survey, construction and inspection will not be as small as 0% of the black and smelly water bodies in urban built areas in my country in 2020, the black and smelly water bodies in urban built areas will be eliminated. Sugar babyThis is a clear request for the management of black and odorous water bodies issued by the National Institute of Economic Affairs (simplified “Ten Water Bodies”). At the same time, provincial housing and urban construction buildings are requested, and various prefectures and cities are in various places..net/”>Sugar daddyTo achieve no large floating objects on the river surface, no dregs on the river bank, and no illegal sewage outlets, Xiangtan City needs to complete 60% (16 articles) of rectification tasks; to complete the management target of black and odorous water by the end of 2020Sugar baby.
In fact, as of the end of 2017, Xiangtan City had completed 6 more in the 16 basics of the ministry and provincial tasks. The results were not easy to find. Baby. None of them can be missed after investigation, expert review, planning and precise inspection.
On the one hand, a municipal black and smelly water management task leader group was established at the municipal level, which was organized by the deputy mayor of the Municipal People’s Government, to divide the specific responsibility of the deputy mayor of the housing and construction task, and each Sugar daddyThe adjustment on Monday formed a black and odorous water rectification task format with “city-level chief, housing and construction chief, departmental cooperation, and park warfare implementation”; on the other hand, Xiangtan City adheres to the concept of “using professional people to do professional things” and is committed to Sugar baby efficiently integrates professional technical talents to create a professional technical team for black and odorous water management, conducting a full process of focusing on quality and effectiveness, focusing on quality and effectiveness.
“At the beginning, we sorted out the classification to prepare a management plan for the precise and scientific and scientific management of Sugar daddy. “Associated responsible persons of the Municipal Housing and Urban-Rural Development Bureau introduced that, first, the district is divided into clean sources such as source purification, surface source purification and internal source purification. The important black and odorous water in Xiangtan City include the discharge of biotechnical sewage, and the discharge of sewage from breeding farms and small industrial sewage along the line; second, the purification waterPurification level and method, 2 of these are heavy purification, and the remaining 22 are light purification. The important method of water purification is to cleanse your life. As long as there are some light heavy metal purification in the three of these, there is steel slag heavy metal purification in the middle of the Nanyang Canal, there is cleanse in the middle of the Longcheng Second-level Canal, and there is cleanse in the first-level canal; the third is to understand the shape and shape of the river line, cross-sectional detail, water flow, the specific status and length of open channels and crypts, as well as the flow area and terrain, the city’s black and odorous water base has no supplementary water source.
After counter-examination certificate, Xiangtan City finally introduced the “hydraulic diversion + geopipe bag water dewatering and dewatering and solidification” process for the national “three lakes” (Taihu, Chaohu, Dianchi Lake) water environment management, which was the first in the province. Yu Zhihong introduced that this work is the most advanced black and odorous water treatment technology in the country today. It has environmental protection and no leakage, resource re-apply, and automatic circle and exposed heads. It has five characteristics: high level of synthesis, soil and water separation, sludge dehydration and solidification, and small amount of space in the air.
According to the management of Weitan River, Xiangtan City, based on its current situation of high sewage absorption along the line, adopts source management, cuts and cuts down sources, and cuts down and closes 30 industrial enterprises along the river. At the same time, we have sufficiently applied wet chemical industry, and small chemical areas are set up at important water outlets along the river. We use the treatment efficiency of natural and ecological moisture to pre-treat the water transfer in the canal. After collecting and processing the films, we can discharge them into the Weitan River through pipelines, so that no black and smelly silt will be a helping hand. And the water “leaking and leaking”.
Finally, in order to ensure the ineffectiveness of adjustment, Xiangtan City clearly confirmed the three levels of adjustment mechanism and investigation mechanism of municipal, departmental and practical Tan Yue. Especially at the municipal level, Xiangtan City has formulated the “one adjustment weekly, one report per month, one process per month, and one inspection per month” adjustment method, and has formulated the “Survey on the Remediation of Black and Smelling Water in the Urban Area of Xiangtan City”, which has divided the deputy mayor to adjust it on time, and deeply solved the difficulties and problems in the rectification process in a timely manner.

One channel, one policy, the “eight steps” locks the entire journey of “black and smelly management”
” After the counter-retrospective survey, we found that every black and smelly water has a special situation of long time, causing disparity in remediation and rich nutrition levels, and the ‘one channel, one policy’ is necessary.” The relevant responsible person of the Municipal Housing and Urban-Rural Development Bureau introduced that for the final management”Black and smelly water bodies”, Xiangtan City has determined eight major rectification measures to “seal, dismantle, intercept, dredge, drainage, manage, renovate, and control”.
In this case, “sealing” means adding a sealing valve at the drainage outlet of the drinking water source protection site in Xiangtan City to strictly prevent sewage from flowing into it; “demolition” means removing water illegal buildings, closing the breeding ground along the line, and reducing sewage discharge; “sewage intercepting” means adding a sewage intercepting pipe network in the entire urban water area to realize the diversion of rain and sewage, and avoiding sewage flowing into the canal; “silting” means using patented technology, using machinery and manual operation, liquidating the black and smelly water silt in the entire area and running out, and flood control efficiency of rivers.
“Drainage”Sugar baby means to change the water system flow by improving the water level, so that summary 2: sewage originally discharged into the Xiangjiang River flows into sewage treatment factory;Escort manila “Management” means strengthening the automatic water efficiency through embankment repair, aquatic plant repair and deep treatment of black and odorous water bodies; “reconstruction” means adding small sewage treatment equipment and reservoirs to black and odorous water bodies with poor water efficiency in the original water system, so that water that cannot be diverted from rain and sewage can be improved; “control” means focusing on long-term management, such as monitoring and warning of water quality in the tree-standing water body should be controlled. According to the request of “River (Lake) Longer”, the tree-standing has a system, standard, team, fee, and TC:
