High wastewater treatment costs have put some wastewater treatment plants in trouble

作者: Release Date: 2019-12-25 Author: Click:

According to an experienced Inner Mongolia sewage treatment plant manager analysis, excluding pipeline maintenance investment, the conventional treatment cost of the sewage treatment plant is 1.11.2 yuan / ton. The average sewage treatment fee income is only 0.79 yuan / ton, and the gap between them has caused a bottleneck in the normal operation of the sewage treatment plant, which is also a problem that China's water industry market needs to solve urgently. The environmental protection project is divided into three branches and seven branches. In the online monitoring data of key state-controlled enterprises regularly released by the environmental protection department before, the sewage treatment plants accounted for the majority of the enterprises whose pollutant discharge exceeded the standard, and some sewage treatment plants even made the list every month. Excessive pollution discharge from sewage treatment plants is the main cause of pollution. It can be found in the monitoring that many sewage treatment plants' total phosphorus, total nitrogen, ammonia nitrogen, solid suspended solids and other indicators will exceed the standard, and some single standards can reach 4 times. This means that sewage is discharged before it is fully treated.

According to China's standards for wastewater treatment plants, in the highest level of Grade A standards, the chemical oxygen demand is less than 50 mg / liter, the pH value is 69, and the worst surface water standards are compared with the worst 5 water standards. , And the same level A standard. This also means that even if the wastewater treated by the sewage treatment plant reaches the highest standards, it is still inferior to Category 5 water. A source from a city's environmental protection bureau pointed out. What's more noteworthy is that the sewage treatment plant's anti-pollution and pollution are related to its deep financial dilemma. Usually, the sewage treatment fee is included in the residents' tap water fee and paid to the local finance. The sewage treatment plant directly invested and operated by the government declares the required expenses every year according to the operation. The Inner Mongolia Sewage Treatment Plant operated by the government in the PPP mode is paid by the local government according to the established contract. However, the fact is that arrears of sewage treatment fees by some local governments have become commonplace. In the past, three sewage treatment plants in the eastern suburbs, western suburbs, and southern suburbs of Xianyang City, Shaanxi Province were owed more than 50 million yuan in arrears. In May 2014, the Environmental Law Enforcement Bureau went to Xianyang for inspection again. As a result, the local government was still in arrears with the company's sewage treatment fee for the year.

The long-term arrears of sewage treatment fees have obvious consequences. Some sewage treatment plants have insufficient operating expenses, equipment is unable to update and maintain, and reduced functional parameters lead to increased maintenance costs and unit power consumption, which can only be operated at low load or even shut down. Specifically, some economically underdeveloped places cannot afford that much money, which has led to shoddy work and some facilities. In terms of technology, the first-level A standard itself is unstable, which will cause some key indicators to exceed standards. For example, in northern winter, total nitrogen may exceed standards. Said the technical director of a water group. On the one hand, there is a shortage of local fiscal payment funds for sewage treatment costs, and on the other hand, the demonization of sewage treatment plant emissions that do not meet standards. So, how to solve such a problem?

If it is imperative for sewage treatment plants to raise bids, it is even more urgent to determine the corresponding price adjustment mechanism. Considering the affordability of local governments, the establishment of a certain price adjustment mechanism is necessary for the normal operation of the sewage treatment plant after the bid increase. An advanced wastewater treatment technology may be good for enterprises, but it may not be applicable to the whole. We must consider the needs for water quality improvement in different places separately, and we cannot do it all. The national standard for sewage treatment in Inner Mongolia is primarily to ensure the national bottom line technology for sewage treatment; local standards and sewage permits can solve special problems in different places.
