Why is it built instead of shipped? There are five difficult problems in the operation of sewage treatment plants in our country

[China] sewage treatment environmental protection online in July 2015, Chongqing proposed in 2017 to achieve full coverage of the township sewage treatment facilities, has been built in Chongqing township of 804 sewage treatment plants, plant operation and maintenance of the state nearly half of the township sewage treatment is not ideal. This is not an isolated phenomenon. In China, the construction of sewage treatment plants has not become a common phenomenon. So, what are the reasons for this kind of sewage treatment plant in China?
Why is it built instead of shipped? There are five difficult problems in the operation of sewage treatment plants in our country
In China, the construction of sewage treatment plants has not become a common phenomenon. So, what are the reasons for this kind of sewage treatment plant in China? Is it difficult to run the sewage treatment plant properly?
From the surface, it is really difficult, otherwise, why nearly 1/3 of the processing plants throughout the country can not play a normal benefit? Even in 2004, the Ministry of Construction issued the "opinions" on the strengthening of urban sewage treatment plant operation supervision, clear requirements of the actual processing load of urban sewage treatment plant put into operation after within a year of not less than the design capacity of 60%, not less than 75% of design capacity within three years, but still did not play a significant role.
In 2015, although the promulgation of "ten water" and the promotion of new environmental protection law, China's sewage treatment plant construction step up, but the operation is still unsatisfactory. At present, Chongqing has built 804 township sewage treatment plants, nearly half of the township sewage treatment plant operation and maintenance is not ideal. The running load of some sewage treatment plants in Hunan is insufficient, and the running load rate of 7 sewage treatment plants is less than 60%.
For 11 years, the operation of our sewage treatment plant has not changed, or the situation has improved little. So, where is the sewage treatment plant running?
First, inadequate pollution control funds, backward equipment
Because most local pollution control funds mainly rely on national and local financial investment, limited sources of funds, in some places due to the supporting pipe network construction is lagging behind, has been built sewage treatment plant construction and operation, and lack of transport". In recent years, the national push for environmental pollution, third party governance, PPP model, but also because of the lack of legal rights protection, complex operation of the project and other issues, the majority of social capital to wait and see, the project landing difficult.
In addition, at present, the monitoring network of overlapping, has not yet formed a water quality monitoring system collaboration, data sharing, complementary advantages of the division of labor between departments, enterprises operating online monitoring equipment, quality management level and the accuracy of the data is not up to the environmental regulatory requirements, some enterprises are still in the forgery and tampering behavior monitoring data.
Two, do not attach importance to sewage treatment work, the management mechanism is not perfect
Some cities do not pay enough attention to the work of sewage treatment and organize and manage them poorly. The cause can not be the normal operation of the sewage treatment plant after the completion of many apparently in many aspects, but experts said that the "root" or invest in the construction of management system is not reasonable, no one of these sewage treatment plant is responsible for real investment. There are many problems, such as imperfect sewage pipe network, inadequate rainfall and sewage diversion project, imperfect operation and management mechanism and lack of specialized management.
Part of the project feasibility study is not sufficient, or even a mere formality, the lack of the study in the project to determine the scale, technology selection, pipe network, centralized processing and distributed layout etc., to project construction and operation of hidden trouble. Lack of necessary scientific proof for technical decision-making administration. For government investment projects and investment projects of enterprises without distinction, not in accordance with the principle of constructing the construction business, the government to organize the construction bidding system is not strictly comply with the project owner responsibility system as well as the design, construction and supervision etc..
Three, there are technical problems
Due to the lack of professional management team, lead to some problems of design ideas and technology selection, facilities such as unreasonable selection of the processing capacity decreased, facilities design defects make the equipment failure, covers an area of unreasonable design of the equipment can be installed in a factory (sand pool at the outlet to install a space for the fine grid, 6mm but because of space limitations, unable to install the accident across devices, often running water, affecting the production, forced to dismantle. Therefore, it is impossible to add a fine grille Other reasons.
Four, the sewage treatment plant as a performance project
Some sewage treatment plants can not run, from the surface, the operating costs are not implemented, the network does not match, but in fact the local government did not establish the correct concept of political achievements, the sewage treatment plant as a performance project. Upon completion, regardless of the requirements, resulting in operating funds can not be in place. The normal operation of treatment in each plant will need millions, tens of millions of money, only the output of the social and environmental benefits, can not pull the GDP rise, also increased fiscal spending, is a thankless task, so it is often under the leadership as "burden". At the same time, some local governments have appropriated and appropriated special funds for treasury bonds so that the constructed sewage treatment can not run normally due to lack of funds.
In addition, there are many safety hazards in sewage treatment plants, which are threats from the outside environment.
