Sewage discharge standards refer to the discharge standards of water pollutants, which are divided into national discharge standards, local discharge standards and industry standards. This standard is based on the water quality requirements of the receiving water body, combined with the environmental characteristics and social, economic and technical conditions, the allowable discharge (concentration) or limit value of water pollutants or harmful factors, and is the basis for judging whether the sewage discharge activities are illegal. The specific implementation standards can be local emission standards or industry standards stricter than national emission standards.
