Satellites, unmanned aerial vehicles, ships and robots launched another special action to investigate and rectify pollution yesterday

on February 15, the Ministry of ecological environment held a special action and pilot work kick-off meeting for the investigation and rectification of the sewage outfall of the Yangtze River in Chongqing, launching the "starting gun" for the investigation and rectification of the sewage outfall of the Yangtze River. According to the arrangement, Yubei District of Chongqing and Taizhou city of Jiangsu Province will be the pilot of this special action. By the end of this year, pilot cities will implement a cancellation system for the regulation of sewage outlets into the river, and one regulation will be completed and one cancellation will be made. According to the relevant person in charge of the Ministry of ecological environment, this will be a tough battle, and we should "prepare to take off a layer of skin"

according to the arrangement and deployment, the investigation scope of this special action is determined to be 11 provinces and cities along the Yangtze River covered by the Yangtze River economic belt. Specifically, the work will focus on the main stream of the Yangtze River (the section from Binshi to Haikou River in Sichuan Province with its roof heat transfer coefficient not greater than 0.1w/m2k), the main tributaries (Minjiang River, Tuojiang River, Chishui River, Jialing River, Wujiang River, Qingjiang River, Xiangjiang River, Hanjiang River, Ganjiang River) and Taihu Lake, involving two municipalities directly under the central government of Shanghai and Chongqing, as well as 58 prefectures and cities and three county-level cities directly under the province in nine other provinces

according to the introduction, the investigation and regulation of the sewage outfall into the river is the basic work to fundamentally improve the quality of the ecological environment of the Yangtze River and the key to the compaction of all parties' pollution control

the relevant person in charge of the Ministry of ecological environment stressed at the meeting that it is necessary to fully understand the complexity and arduousness of the investigation and regulation of sewage outlets. Although the sewage outfall is small, the problem is not simple, "one hair touches the whole body", which can be described as "a small sewage outfall, a big stage for environmental protection". The special action will connect the main consumption areas, as shown in Figure 1. In about two years, it will focus on completing the four main tasks of "inspection, testing, tracing and treatment". This will be a tough battle, and we should "prepare to take off a layer of skin"

the regulation of sewage outlets into the river implements the cancellation system

how to check specifically? It is reported that on the basis of the original work of regular inspection and revision of experimental machines, the comprehensive use of satellite remote sensing, aerial photography of unmanned aerial vehicles, unmanned ship monitoring, intelligent robot detection and other advanced technical means and manual troubleshooting, to comprehensively find out the industrial sewage outlets, domestic sewage outlets and all kinds of sewage outlets directly and indirectly discharged

measurement means that all localities, in accordance with the principle of checking and monitoring at the same time, formulate a monitoring plan for the sewage outlet into the river, so as to "measure clearly" the water quality of the sewage outlet, understand and master what pollutants are in the water and what the current discharge situation is

tracing is to trace the source of the sewage outlet with prominent sewage discharge problems found in the monitoring, find out the context of the sewage and clarify the sewage discharge

treatment is to carry out the cleaning and remediation of sewage outlets in a classified and step-by-step manner on the basis of investigation, monitoring and traceability, according to the principle of "one policy for each outlet". The number cancellation system is implemented for the regulation of sewage outlets into the river. One regulation is completed and one number is cancelled

"first of all, it is necessary to find out how many outlets discharge pollutants into the Yangtze River, where they are discharged, who is discharging them, what is discharged, and how much?" The relevant person in charge of the Ministry of ecological environment pointed out that the special action should firmly grasp the "bull's nose" of the sewage outfall into the river, and figure out the most important basic "bottom number" of the sewage outfall into the river, so as to provide guarantee for improving the quality of the ecological environment of the Yangtze River

According to the introduction, taking into account the working basis, natural characteristics, meteorological conditions and other factors, the Ministry of ecological environment decided to take Yubei District of Chongqing and Taizhou city of Jiangsu Province as the pilot of this special action

the pilot cities will comprehensively investigate the situation and existing problems of various sewage outlets, implement classified management, implement remediation measures, and form effective, replicable and replicable technical specifications and work procedures. Other cities follow up "stubble pressing", learn from the experience and practice of the pilot, and combine the local reality to comprehensively carry out the investigation and rectification work

according to the work requirements and adopting the combined use technology of edge hot oil spray system (HES) and multi section rolling oil spray, the main tasks of the pilot cities in the first half of 2019 are "inspection" and "measurement", that is, inspection while measurement; In the second half of the year, we will do a good job in "tracing and governance" as a whole. For other cities, the main task in the first half of 2019 is to learn from the pilot experience, formulate and carry out the work of "inspection and testing" in various cities according to the technical scheme and work experience summarized from the pilot

"the biggest difference between this investigation and the previous work is that as long as the 'hole' draining the Yangtze River should be checked." The relevant person in charge of the Ministry of ecological environment specially stressed that the investigation work is not a "comeback", but an expansion and deepening on the basis of the original work

notice of the State Environmental Protection Administration on carrying out the standardization and remediation of discharge outlets (revised version on June 5, 2006)

(revised according to the decision of the State Environmental Protection Administration on Amending the notice on carrying out the standardization and remediation of discharge outlets on June 5, 2006)

the pilot work of standardization and remediation of discharge outlets carried out in some provinces and cities across the country has achieved results through the efforts of the provinces and cities participating in the pilot work. The pilot experience shows that the standardized regulation of discharge outlets is a basic work for the implementation of pollutant emission control, and plays a role in strengthening environmental supervision and strengthening environmental law enforcement. In order to further strengthen the on-site supervision and management of pollution sources and ensure the realization of the goal of "one control and two standards" in 2000, after research, it has been decided to carry out the standardized regulation of discharge outlets. The relevant issues are hereby notified as follows:

article 1

the standardized regulation of discharge outlets is to implement the implementation of the permanent control of pollutant discharge proposed by the State Council and the standard discharge of national industrial pollution sources by 2000, municipalities directly under the central government, provincial capital cities, special economic zone cities It is an important basic work for the legalization and quantitative management of pollution sources to meet the requirements of the functional areas of coastal open cities and key tourism cities. Environmental protection departments at all levels should attach great importance to it, strengthen leadership and conscientiously organize it. Environmental supervision institutions should earnestly undertake the specific tasks of implementation

Article 2

all new, expanded, reconstructed and time limited pollution discharge units must build standardized discharge outlets while building pollution control facilities, and as a necessary part of the implementation of the "three Simultaneities" system of environmental protection and one of the contents of project acceptance

Article 3

in the basins of Huaihe River, Haihe River, Liaohe River, Taihu Lake, Chaohu Lake and Dianchi Lake, sulfur dioxide pollution control areas, acid rain control areas and Beijing, the discharge outlets of pollution sources that meet the standard within the time limit of 2000 must be standardized to meet the needs of the standard work. Other qualified regions and pollutant discharge units should also carry out standardized regulation of discharge outlets

Article 4

environmental protection departments at all levels shall prepare standardized remediation plans for discharge outlets, fill in the schedule, and report them level by level for the record. It is necessary to take the completion of supervising and urging the discharge units to carry out the standardized treatment of discharge outlets as one of the assessment contents of environmental supervision work, and organize inspection

Article 5

The discharge outlet signs are the legal signs for monitoring, sampling, supervision and management of pollutants discharged by pollutant discharge units

Article 7

the funds required for the standardized regulation and construction of discharge outlets are mainly raised by the pollutant discharge units themselves, and the environmental protection department can give appropriate subsidies from the environmental protection subsidy funds for pollution control

this requirement is formulated in accordance with the national environmental protection laws, regulations and standards and the relevant provisions of the State Environmental Protection Administration

the standardized regulation of discharge outlets is one of the basic work of implementing the total pollutant control plan. The purpose is to promote the pollutant discharge units to strengthen management and pollution control; The environmental supervision department should strengthen law enforcement, better perform the duties of "three inspections, two adjustments and one charge", and gradually realize the scientific and quantitative management of pollutant discharge

this requirement is applicable to the standardized renovation of the discharge outlets of existing pollutant discharge units and the standardized construction of the discharge outlets of new and expansion projects

the standardized regulation of the discharge outlet should follow the principle of convenient collection of samples, convenient measurement and monitoring, and convenient daily on-site supervision and inspection

the standardized regulation of discharge outlets can be carried out step by step. The discharge outlets listed in the national, provincial and municipal key pollutant discharge units and the total discharge control of 12 pollutants should be rectified first

the standardized discharge outlet of key pollutant discharge units shall be installed with metering devices and pollution control facilities recorders, and conditions shall be created to establish a microcomputer monitoring network. If it is not installed temporarily, the installation position shall be reserved during the construction or renovation of the discharge outlet. Simple metering and recording devices can be installed at the standardized discharge outlet of general sewage discharge units
