II. Priorities and responsibilities of remediation
The river pollution control work in Xicheng District is determined, and the principle of combining territorial management with centralized management and "whoever pollutes will treat" is adhered to. The Municipal Environmental Protection Bureau and the Anding District Government are responsible for taking the lead in grasping the overall situation, formulating implementation plans, doing a good job in macro-supervision and coordination guidance, and strengthening supervision and inspection. City, district housing and construction, industry and information, water affairs, development and reform and other functional departments and responsible units according to their respective responsibilities, do a good job in the implementation of various pollution control measures.
(I) Industrial sewage treatment
The Anding district government takes the lead, and the municipal and district departments of environmental protection, industry and information, housing and construction cooperate with each other, and relevant enterprises implement it.
1. It is necessary to strengthen the supervision of pollutant discharge enterprises, especially the potato starch production enterprises, make arrangements in advance, make arrangements as early as possible, strengthen inspections, urge enterprises to operate pollution control facilities normally, and strive to meet the discharge standards. In principle, enterprise wastewater must achieve three-stage precipitation. Enterprises that fail to meet the precipitation standards should be urged to build pollution control facilities before the end of August; Enterprises without pollution control facilities or with abnormal operation of pollution control facilities are not allowed to start production. Enterprises that illegally discharge industrial wastewater should be severely punished, and if the circumstances are serious, they should be shut down according to law.
2. For the six enterprises that have not entered the industrial sewage pipe network, the responsibility shall be contracted, and the relevant departments in the urban area shall urge the sewage to be connected to the industrial sewage pipe network within a time limit. The District Bureau of Industry and Information Technology is responsible for urging Longhai Dairy Company to access the industrial sewage pipe network before the end of May, and urging Hongxuan Starch Company to transform the branch pipe of the south side of Liberty Street to ensure that all sewage enters the industrial sewage pipe network. District Animal Husbandry Bureau and Fengxiang Town Government are responsible for urging Zhangjiawan Wanggang Breeding Factory to be connected to the sewage pipe network before the end of May.

Resolutely put an end to the direct discharge of sewage from industrial enterprises into rivers.
3. The Anding district government should instruct the relevant departments to organize professionals to regularly and irregularly inspect the pipelines connected to the industrial sewage pipe network. If the network management interface does not meet the standard, it should guide and urge the relevant units to carry out technical transformation to prevent problems such as leakage due to the small diameter of the interface. Dredge the pipe network to ensure the smooth flow of industrial sewage pipe network.
4. The Municipal Commission of Industry and Information Technology and the Anding District Government shall, in strict accordance with the Circular Economy Development Plan of Dingxi City, gradually move the sewage discharge enterprises originally scattered in urban areas into industrial parks in a planned way during the Twelfth Five-Year Plan period, so as to achieve centralized disposal and discharge of industrial wastewater up to the standard.
5. The Anding district government will take the lead to start the implementation of the second phase of industrial sewage collection and treatment project as soon as possible, further strengthen the construction of pollution control infrastructure, extend the pipe network to the north, and set the Xicheng District to? The enterprise sewage along the mouth is gradually collected into the industrial pipe network for centralized treatment and discharge.
(II) Domestic sewage treatment
1. Led by the Municipal Housing and Construction Bureau, on the basis of formulating the domestic sewage treatment plan, the responsible units are urged to connect all the domestic sewage that has entered the pipe network but has not been connected to the pipe network as far as possible to the domestic sewage pipe network or industrial sewage pipe network for centralized treatment before the end of the year, so as to minimize the domestic sewage discharge in urban rivers.
2. The Municipal Bureau of Housing and Urban-Rural Development is responsible for starting the implementation of the second phase reconstruction and expansion project of Qingyuan Sewage Treatment Plant as soon as possible, further expanding the coverage of sewage pipe network in combination with the renovation of shanty towns and villages in the city, and implementing rain and sewage diversion to solve the problem of river pollution caused by domestic sewage in residential areas. Especially for Nanshan New Village, Meteorology New Village, Park Bridge and other bungalows scattered along the river, residents' domestic sewage should be collected into domestic sewage pipe network or industrial sewage pipe network for treatment, and direct discharge is strictly prohibited. It is necessary to cooperate with the Anding district government to do a good job in the renovation of the existing pipelines integrating flood discharge and sewage discharge at Majiachagoukou and the south side of Liberty Street to ensure the sewage receiving capacity.
3. The Anding district government will take the lead, and the municipal, district administration for industry and commerce, food and drug administration and district sanitation station will cooperate to formulate specific management measures to control the small restaurants along the street from dumping sewage into the street. Require small restaurants and food vendors along the street to deal with kitchen waste, sign a letter of responsibility with the garbage recycling unit recognized by the environmental protection department, and the recycling unit will recycle it uniformly; The swill shall be collected and treated in a unified way, and it shall not be thrown at will. Those who refuse to make corrections shall be dealt with by the relevant departments according to law. Strictly prevent small restaurants from directly discharging swill and other wastewater into the urban sewage pipe network, resulting in high chemical oxygen demand at the inlet of urban sewage treatment plants.
(III) Treatment of aqua privies along the river
The Anding district government, in combination with the urban development plan, instructed relevant departments to put forward a treatment plan for aqua privies before the end of March, and the municipal and district governments raised funds to give appropriate subsidies, so as to completely complete the demolition and renovation of aqua privies along the river before the end of August.

(5) Take a long-term view and prevent rebound. Comprehensive management work must be thorough and meticulous, and resolutely prevent the "rebound" phenomenon from happening. On the one hand, adhere to high standards and fast pace, do every job well, ensure all-round seamless coverage, leave no dead ends and blind spots, and ensure that urban river pollution control has achieved remarkable results in a short period of time. On the other hand, we must focus on the long-term, establish and improve the management system, and gradually form a set of long-term mechanisms for urban river pollution control, so as to create a good production, living and living environment for the general public.
(6) increase publicity and create an atmosphere. In accordance with the spirit of the joint meeting of the municipal government on river pollution control, we will further unify our thinking, clarify the tasks and control measures, and announce the urban river regulation plan on radio, television or newspapers. In the stage of comprehensive improvement, make full use of activities such as "World Water Day" and "World Environment Day", increase publicity efforts, distribute publicity materials, and publicize the importance of protecting rivers. Publicly report the telephone number and e-mail address, so that the masses can actively participate in the management activities of urban rivers. Conduct comprehensive publicity and in-depth reports on the rectification situation, make it a household name, and strive to form a good social atmosphere in which the government takes the lead, departments cooperate and the whole people participate.
The Scheme for Comprehensive Treatment of River Pollution in Dingxicheng District has been studied and agreed by the municipal government, and the office of the municipal government has issued a document to relevant departments to organize its implementation. It is hereby announced.
River regulation scheme (II)
"Can you imagine that one day, our honeycomb drainage modules will be laid on both sides of the river? There are various purified plants on the surface of the module, forming two green barriers that can be played and used. " On a scorching summer afternoon, Zhuge Yixian, a student majoring in agriculture at Zhejiang A&F University, stood by the bank of Shuanglonggang River in Hangzhou and talked about the treatment of this smelly black river, but he couldn't hide his excitement.
Recently, the River Supervision Center of Hangzhou Urban Management Committee and "Green Zhejiang" jointly launched a creative competition for improving the water quality of urban rivers, and held discussions on "investigation and supervision", "engineering management" and "green and smooth"
