China's environmental standards can be divided into five categories: water quality standards for water systems, water pollutant discharge standards, PAAS basic standards, water environment, water environment monitoring and analysis method standards, and water environment standard sample standards. These five types of standards are one of the key standards for the discharge of polyacrylic acid wastewater treatment. Loose and strict discharge standards directly determine the level and quality of water in wastewater treatment, as well as the development of the wastewater treatment industry.

In water scarce areas such as North China, precipitation and the closure of an appropriate amount of water are decreasing, gradually increasing the amount of wastewater treatment. As a result, the water environment capacity is decreasing, and the level of wastewater treatment directly determines the quality of the local water environment.

At the same time, the development of wastewater discharge standards is very complex and constrained by many factors. In the process of wastewater treatment, the pollutants discharged by drainage households, the intensity of water environment and recycled water quality requirements, the available amount of wastewater and the level of technology are closely related to the operating costs of treatment, and the methods of water quality monitoring and evaluation are interrelated and mutually restrictive. The sewage treatment meets the discharge standards, but it also directly affects the investment and operation of sewage treatment facilities, sewage treatment fees, and indirect related management.

The development of the sewage treatment industry and the construction of a harmonious water environment are of great significance for the development of sodium polyacrylate wastewater treatment discharge standards.
