: r br How are these sewage treatment plants operating? Has the sewage been treated? Does the treated sewage meet the standards?
: r br
: r br The same problem is even more serious at the sewage treatment plant in Damuchang Town, Fang County, Hubei Province. The project has been in intermittent operation since its completion in March. According to data provided by Shiyan City, in recent years, the sewage treatment plant with a designed daily processing capacity of tons has averaged only tons of sewage treatment per day.
: r br As the largest township sewage treatment plant in Honghu City, the Fengkou Town sewage treatment plant is designed to process tons of sewage per day. However, after being put into operation for more than a year and a half, the plant can still only operate at half capacity. It takes a genius to collect a day's worth of operating wastewater. Factory administrator Guo Shengbiao said.
: r br According to data provided by the Hubei Provincial Department of Housing and Urban-Rural Development, there are currently a total of township domestic sewage treatment plants in the province, with the scale ranging from tons to tons. However, only the seats are operating normally. They open and stop when there are seats, and the seats are basically idle. Among the township sewage treatment plants in normal operation, the one with the highest operating load rate only reaches %, and half of them are below %.
: r br The audit results of the rural environment contiguous comprehensive improvement funds released by Henan Province in 2020 showed that among the sewage treatment systems that were completed in 2016, one was idle, one was not operating normally, and the other was not operating normally. There are only sets.
: r br The reporter learned from the Liaoning Provincial Environmental Protection Department that there are currently a total of sewage treatment plants in Liaoning Province, with an average operating load rate of % and a centralized treatment rate of urban sewage in the province of %. In places such as Fuxin City and Fumeng County, Jianchang County, Huludao City, Liaoning Province, some township sewage treatment plants cannot fully operate normally, making it difficult for township residents' domestic sewage to be effectively treated.

: r br Amudbu said that after he called the mayor’s hotline to report the problem, he got a reply: The relevant departments also know about this matter, but the Kunming Third Sewage Treatment Plant cannot process so much sewage, and they have to wait for other This problem can only be solved after the sewage treatment plant is built. They discharge sewage almost every day, a little less in the dry season. In the rainy season, the sewage is very large and smells all the way.
: r br On March 1, the reporter came to the Kunming Third Sewage Treatment Plant and found that under the sewage inlet valve that should have been closed tightly, a huge amount of sewage flowed out from the valve, and the turbid and smelly sewage flowed along the As you go along the Yunliang River, the banks of the Yunliang River are all dark brown. Not far from the valve, the water discharged from the sewage treatment plant is relatively clear. The two streams of water, one clear and one turbid, mix and turn into dark yellow smelly water, which flows into Dianchi Lake Caohai.
: r br Tens of thousands of sewage flows through the Yunliang River every day, but the maximum treatment capacity of the sewage treatment plant is only 10,000 square meters per day. The untreated sewage will flow into Dianchi Lake. In an interview with the media, the person in charge of the Kunming Dianchi Lake Management Comprehensive Administrative Law Enforcement Corps Office said.
: r br Due to various reasons such as rapid urban expansion and the planned pipe network design and processing capacity of sewage treatment plants, many sewage treatment plants are unable to process, similar to the Kunming Third Sewage Treatment Plant. The reporter learned that in 2019, the average daily operating load rate of Hefei urban sewage treatment plant reached %.
: r br However, because the construction of supporting pipe networks in some sewage treatment plants has not kept up, some urban sewage cannot be effectively collected and treated, and is directly discharged into rivers. There is a Qingling River within the secondary protection zone upstream of Wuhan Baishazhou Water Plant. Whenever there is too much rain, the accumulated water in the urban area flows into the Qingling River and then is discharged into the Yangtze River through the pumping station. The reporter went up the river and found that there was a lot of silt cleared from the river on both sides of the Qingling River, but the river water was still light black. At the Qingling River bridgehead, a sewage outlet is pouring black water into the river. It is obvious that the sewage has not entered the collection pipe network.

: r br This month, the Anhui Provincial Environmental Protection Department supervised the listing of the Bagongshan Sewage Treatment Plant of Huainan Capital Water Co., Ltd. for environmental violations.
: r br This sewage treatment plant was built in 2016, but has never passed the completion environmental protection inspection. During the inspection, relevant staff of the Provincial Environmental Supervision Bureau found that the factory's standard improvement project was implemented at the end of the year, but the environmental impact assessment and approval procedures had not been completed, and the factory's disinfection facilities were not in operation. Outlet sampling and monitoring results showed that, The ammonia nitrogen in the wastewater from this treatment plant exceeded the standard by more than 1/2 times, and the fecal coliform bacteria exceeded the standard by more than 1/2 times.
: r br The Jiangsu Provincial Environmental Protection Department released a list of enterprises that exceeded the standard in supervisory monitoring of key nationally controlled pollution sources in Jiangsu Province. In the third quarter of this year, among the enterprises that exceeded the standard discharge, there were 3 sewage treatment plants, accounting for up to %. In March 2019, Shaanxi Province notified the results of special law enforcement inspections of urban domestic sewage treatment plants. Among the sewage treatment plants in the province, on-site sampling and inspection results showed that 100% of them discharged sewage in excess of the standard.
: r br Zhang Jingyu, a researcher at the Urban Construction Division of the Anhui Provincial Department of Housing and Urban-Rural Development, said that the existing excessive discharge projects of sewage treatment plants mainly include fecal coliform suspended solids and other indicators, and the main chemical aerobic total phosphorus and total nitrogen The emission compliance status of other indicators is relatively good. Zhang Jingyu analyzed that the current emission standards are newly introduced every year, and there are clear standards for the emissions of different water systems, different types, different enterprises, and different projects. However, many sewage treatment plants planned and constructed before this failed to meet the new standards. Requirements for design and construction have resulted in excessive emissions to a certain extent.
: r br However, some people in the industry believe that the difficulty of survival of sewage treatment plants, weak profitability, and large investment in upgrading and upgrading standards are also objective reasons for the failure to meet discharge standards. In addition, there are also some sewage treatment plants that do not lower standards in accordance with regulations.
: r br Wang Jiaquan, a professor at the School of Resources and Environmental Engineering at Hefei University of Technology, said that sewage treatment plants are supposed to centrally treat sewage and are essentially environmental protection institutions and facilities. However, unqualified emission indicators are a common problem everywhere. This Some environmental protection facilities have become sources of pollution.

: r br How have environmental protection facilities become a source of pollution?
