The rectification of black and odorous water is not only the highlight of the battle against pollution, but also the focus of public concern. What was the effectiveness of water control in Guangzhou last year? What new goals are there this year? Recently, the reporter learned from the Guangzhou Municipal Water Affairs Bureau that at present, the city’s 147 black and odorous rivers have achieved phased results. This year’s water control work will continue to be hard, hard to overcome, and completely eliminate black and odorous water bodies; “Bi Road” creates an ecological corridor with “the river clears the green, the fish is shallow”, “the water is rich and the egrets are in groups”.
Water control transcript in 2018
Demolition of illegal management within the scope of river management was 493.34 million cubic meters; 3 sewage treatment plants were built, 12 construction projects were started, new sewage treatment capacity was 220,000 tons/day, and newly built sewage pipe network was 3430 kilometers.
The city-level river chief has accumulated a total of 108 river cruises, and the district, town, and village-level rivers have accumulated a total of 783,000 rivers.
The realization of 35 black stinking rivers basically eliminated black odor, and the water quality of 112 black odor rivers continued to improve. The water quality of the Yagang section was obviously improved in the second half of the year. The 23 tributaries of Liuxi River eliminated the bad V class and took the lead in realizing rural domestic sewage in the province. Governance administrative villages are fully covered.
Water control target in 2019
By the end of 2019, the new expansion of five sewage treatment plants will be completed, the newly added sewage treatment capacity will be 480,000 tons/day, the construction of not less than 1,500 kilometers of sewage pipe network will be completed, and the second batch of 49 urban villages will be completed.
The unified management of public drainage facilities was comprehensively promoted, and the central urban area basically realized the unified management of public drainage facilities at the end of March 2019.
Last year, newly built sewage pipe network 3,430 kilometers
A set of data fully shows that 2018 is an unprecedented year for water control in Guangzhou: 1.7 million buildings were washed, 3,341 kilometers of pipes were washed, 110,000 wells were washed, 1,033 rivers were washed, 5,218 water outlets were rectified, and cleansing and rectification were promoted. There were 58,300 places, and the illegal construction of the river management area was 493.34 million cubic meters; 3 sewage treatment plants were built, 12 construction projects were started, and the new sewage treatment capacity was 220,000 tons/day; the newly built sewage pipe network was 3430 kilometers; The province has fully implemented the long system of the river system, realizing the full coverage of the river length system in the city, and implementing 3,030 rivers and 828 lakes.
At the same time, on the basis of the four-level rivers, the city-level river chiefs of the nine major river basins were innovated, and the members of the municipal party committee and the four members of the city team served as river basins, further promoting the key work of water environment management. The city-level river chief has accumulated a total of 108 river cruises, and the district, town, and village-level rivers have accumulated a total of 783,000 rivers.
After the hard work of climbing over the ridge, it ushered in the continuous improvement of the city’s water environment: in 2018, 35 black odorous rivers were basically eliminated from black odor, and 112 black odorous rivers continued to improve water quality. The water quality of the Yagang section was obvious in the second half of the year. Better, the 23 tributaries of Liuxi River eliminated the inferior V class, and took the lead in realizing the full coverage of the rural sewage treatment administrative village in the province. They successfully withdrew from the national “water environment lag behind the standard” and were selected as national demonstration cities for black and odorous water remediation. Jingtaiyong was reported by the Xinhua News Agency as a typical project for green development, and it was the first case of China’s comprehensive review of the reform of the ecological civilization system since the Third Plenary Session of the 18th CPC Central Committee.
Water pollution, pollution and illegal construction are the key
After the concerted efforts of the whole city, the water control work in Guangzhou has achieved certain results, but the problem of heavy work and tight time in Guangzhou black and odor water remediation work still exists.
Specific performance: First, the “disintegration” site is not completely rectified, and the resurgence of resurgence still exists. Some urban villages and village-level industrial parks gather a large number of scattered and polluting enterprises, and the waste water flows directly into the river, affecting the operation of the sewage treatment plant; The problem of illegal construction of rivers invading and occupying rivers still exists. The river crossings still need to be opened, especially the historical legacy and some property-owned buildings are difficult to clear and demolish, affecting the laying of sewage interception pipe networks.
The relevant person in charge of the Guangzhou River Office said: “For the rivers with problems, all districts must implement the rectification and ensure the elimination rate of black and odorous water in the urban built-up area reaches 90%. For this goal, we have no retreat. Go all out and be sure to reach it.”
Complete the expansion of 5 sewage plants by the end of the year
In 2019, Guangzhou will continue to conscientiously implement the central and provincial decision-making arrangements, strictly implement the provincial total river command, adhere to the problem-oriented, and fight the battle against black and odorous waters. In the next step, on the basis of the phased results of the 147 black and stray river remediation, Guangzhou will continue to fight hard and overcome difficulties, speed up the review of 112 black and odorous water bodies, and strive to complete the micro-water body before the end of 2019. Remediation tasks, stepping up in 2020, further improve the river water quality. At present, the 112 river surge main projects that have been included in the national black and odor water remediation platform have been completed, and the self-evaluation by each district has achieved the goal of “first-time results”.
In response to the existing problems, Guangzhou mainly does the following work in 2019:
In accordance with the “Opinions on Strengthening the Responsibility of the River Chief to Win the Black and Stinky Water Body Destroyer”, select and match the rivers and lakes at all levels; explore the establishment of incentive mechanisms, optimize the inspection and supervision mechanism, and urge the rivers and lakes to perform their duties.
Do a good job of intercepting the source. According to the idea of basin as the system, grid as the unit, wall chart operation, and sales number management, the pollution source operation map is drawn based on the village and grid as the basic unit, and the “health whistle, department report” linkage mechanism is adopted to promote “scattering pollution”. “Remediation and “dismantling”, eliminating pollution sources one by one.
Comprehensively promote the rectification of “scattering and pollution” sites. Fully implement the main responsibility of the local government and grassroots river chiefs in the “disintegration” site, and divide the pollution source combat units in the “scattering and pollution” places with villages as the unit, and promote the “disintegration” sites one by one to ensure the villages pass through. Accelerate the promotion of illegal construction and rectification on both sides of the river. With no less than 6 meters from both sides of the strait as the bottom line, we can fully understand the stock of built-in structures in the management area of black and odor rivers.
Strongly promote the construction of sewage facilities. Ensure that the new expansion of five sewage treatment plants will be completed by the end of 2019, the newly added sewage treatment capacity will be 480,000 tons/day, the construction of not less than 1,500 kilometers of sewage pipe network will be completed, and the second batch of 49 urban villages will be completed.
Continue to promote the establishment of a long-term management mechanism for drainage and river surges. The unified management of public drainage facilities was comprehensively promoted, and the central urban area basically realized the unified management of public drainage facilities at the end of March 2019. Accelerate the transformation of the merged canal and the establishment of the drainage unit.
In accordance with the principle of “finding the bottom, one channel, one policy, formulating the plan, and implementing it step by step”, the reform of the merged canal box is taken as the starting point, and the river “long-term long-term clear” governance is gradually carried out.
Create an ecological corridor with “water clearing green and fishing shallow bottom”
After the river is not black and smelly, the water quality and environment should be further improved. The relevant person in charge of the Guangzhou Water Affairs Bureau revealed that this year, we should use strategic vision and systematic thinking to plan scientifically, build Guangzhou “Baidao” with high standards, and create an ecological environment of “the river clears the green, the fish is shallow,” and the “water plants are beautiful and the egrets are in groups”. Corridor. Full implementation of the River Beauty Action, introduction of implementation plans, clear time limits and responsible persons, implementation of water pollution prevention, improvement of water environment, restoration of water ecology, protection of water resources, protection of water safety, management of water space, upgrading of water landscape, promotion of water culture Eight major tasks.
At present, Lichee Bay Chung in Liwan District, Tuhuayong in Haizhu District, Liedeyong in Tianhe District, Cheyongyong, Wuyong, Shuanggangyong in Huangpu District, Yonghe River in Zengcheng District, Heyong and Danshan River in Panyu District University City have been The water-clearing green and fish-fishing shallow bottom demonstration rivers will accelerate the construction of clearing and diversion, drainage unit compliance, landscape improvement along the river, and related projects. All relevant projects are expected to start in the first half of 2019, all in the first half of 2020. Completed.
Rise steel provide SSAW steel pipe, LSAW steel pipe, flange,elbow,tee,reducer for this project.
