The reporter learned from the regular meeting of the Ministry of Ecology and Environment on February 28 that in 2018, China's water pollution prevention and control work has made new positive progress: the newly revised Water Pollution Prevention and Control Law was officially implemented. The Ministry of Ecology and Environment will be established to open up the ground and underground, onshore and water, land and sea, cities and rural areas, and promote the unified supervision of water ecological environment protection. The implementation of the Yangtze River protection and restoration, centralized drinking water source environmental protection, urban black and odor water treatment, agricultural and rural pollution control and comprehensive management of the Bohai Sea battle plan (or program), comprehensively launched a battle against water pollution.

First, positive progress has been made in the remediation of black and odorous water bodies. By the end of 2018, 95% of the 1062 black and odorous water bodies in 36 key cities eliminated or basically eliminated black odor, achieving the annual target of the tough battle. According to incomplete statistics, the investment in 36 key cities directly used for the treatment of black and odorous water bodies totaled more than 114 billion yuan. A total of 20,000 kilometers of sewage pipe network and 305 sewage treatment plants (facilities) were built, with a daily processing capacity of 14.15 million tons. Effectively improved the level of water pollution prevention and control. Among the 101 national control sections involved in the black and odorous water bodies of 36 key cities, the proportion of I-III water quality increased by 3 percentage points year-on-year, and the proportion of inferior V categories decreased by 4.9 percentage points, which made an important contribution to the improvement of water quality in the country. It is necessary to point out that the public and public opinion supervision have played a huge role in the rectification of black and odorous water bodies. In the course of the special action, more than 3,000 people reported the information, and the news media published more than 200 reports, effectively transmitting pressure and motivation.

The second is to continuously strengthen the environmental supervision of drinking water sources. Carry out special action on environmental protection of centralized drinking water sources in the country, and investigate the water sources of county-level cities in the Yangtze River Economic Belt and other prefecture-level cities. A total of 6 621 problems were found in 1,586 water sources in 276 cities, of which 6242 were The rectification was completed before the end of 2018. Effectively guarantee the water quality safety of the South-to-North Water Diversion Project. By the end of 2018, the Middle East Line of the South-to-North Water Diversion Project had a total water diversion of 22.39 billion cubic meters.

The third is to promote the construction of pollution control facilities in industrial parks. More than 97% of provincial and above industrial parks have built centralized sewage treatment facilities and installed automatic online monitoring devices, which is more than 40 percentage points higher than the implementation of “Water Ten” in 2015.

The fourth is to seriously implement reform measures. Set up a basin ecological environment supervision and management institution, deepen the reform of the management of sewage and sewage into the river, and explore and optimize the management of water function zones and water environment control lists. The Joint Water Resources Department has comprehensively promoted the implementation of the river (lake) system and compacted local governments' responsibility for water pollution prevention and control. In 2018, the proportion of excellent water quality sections of surface water in the country increased by 3.1 percentage points year-on-year to 71%; the inferior V category decreased by 1.6 percentage points to 6.7%. Among them, the proportion of excellent water quality in the Yangtze River Basin increased by 3 percentage points year-on-year, and the inferior V category decreased by 0.4 percentage points. The quality of the national water environment continued to improve, and the clear water defense war started well.

The relevant person in charge of the Ministry of Ecology and Environment said at the press conference that although the water pollution prevention and control has made positive progress, the imbalance and uncoordinated problems still face prominent problems. Some local cities and industrial environmental infrastructures have more debts, and the water ecological damage in the river basin is relatively poor. Generally, the risk of aquatic ecological environment remains high. First, some local environmental infrastructures have a lot of debts, and various irregularities in the sludge treatment process still exist. Second, the water ecological damage in the basin is relatively common, and the river ecological flow is insufficient. Third, the risk of water ecological environment in some areas remains high, and the environmental protection management basis for drinking water sources in rural areas is still weak.

"The situation of water pollution prevention and control is still grim, and the task of attacking the hard battle is arduous and heavy." Zhang Bo, director of the Department of Water Ecology and Environment of the Ministry of Ecology and Environment, said at the press conference.

In the next step, the Ministry of Ecology and Environment will focus on improving the quality of the water ecological environment, focusing on the Yangtze River Economic Belt and the Bohai Rim Region, and comprehensively promote the battle against water pollution. First, lay a good fight against the black and odorous waters in the city (black), and strive to eliminate more than 90% of the black and odorous water bodies in the built-up areas of prefecture-level cities through two years of efforts. The second is to basically eliminate the inferior V-class national control section (deterioration) in key areas. By 2020, the Yangtze River basin and the Bohai Sea into the sea will basically eliminate the inferior V-class national control section. The third is to strengthen the pollution source remediation (polluting), carry out special investigation and rectification actions of the “three phosphorus” (phosphorus mine, phosphorus chemical enterprise, and phosphogypsum bank) in the Yangtze River, implement the special action of remediation of sewage treatment facilities in the industrial zone of the Yangtze River Economic Belt, and carry out the Yangtze River into the river. Sewage outlets and pilots for the investigation and remediation of sewage outfalls into the Bohai Sea area. The fourth is to protect the drinking water source (guarantee source), comprehensively carry out the investigation and assessment of rural drinking water sources of “thousand tons of people” (daily water supply of 1,000 tons or serving 10,000 people), and further promote the investigation and rectification of township water sources in the Yangtze River Economic Belt. The fifth is to improve the long-term management mechanism (system), and to establish a sound integrated management system for the basin ecological environment.
