The problem of wastewater treatment in steel mills is difficult to apply in practice. All over the country is strengthening the construction of sewage collection, treatment and recycling by using decentralized sewage treatment technology.Today we summarize the difficulties encountered in the practical application of decentralized sewage treatment technology.

First of all, although China has gradually improved the relevant laws and regulations on sewage treatment, water ten policies provide policy support for sewage treatment.However, with the rapid development of China's economy, the problem of water pollution is becoming increasingly serious. Many relevant laws and regulations have not been updated and improved in time, resulting in the original relevant laws and regulations cannot meet the needs of modern sewage treatment. Therefore, it is necessary to constantly establish and improve relevant laws and regulations.If the sewage discharge standard is clearly stipulated, the relevant law enforcement personnel can follow the law in the process of sewage prevention and control, so as to improve the current situation of water pollution.

Secondly, China's sewage treatment equipment management and evaluation mechanism is not perfect, leading to some problems in the actual operation process.Therefore, when applying the technical standard of decentralized sewage treatment, the area should adopt the corresponding decentralized sewage treatment technology and its operation management according to the local actual situation, the characteristics of water source generation and geographical conditions, and scientifically formulate the corresponding sewage discharge standard according to the rural economic development.

Then, China's investment in sewage treatment equipment is insufficient, making it difficult to carry out large-scale sewage treatment.For a long time, China's capital investment in sewage treatment equipment, mainly depends on the normal financial input at the county level, and the county public finances, and most do not have to pay the cost of sewage treatment will cause sewage treatment equipment in the construction, operation and management ", etc., make the sewage treatment effect.

The operation management mode and sewage pipe network construction method of centralized treatment cannot be completely copied in the process of wastewater treatment in steel mills.Relevant departments should speed up the formulation of construction, installation, maintenance, management and maintenance laws and regulations related to decentralized sewage treatment and corresponding detailed standards.
