First of all, it is necessary to control from the source, pay attention to the selection of production raw materials and production auxiliary materials, and take scientific and reasonable measures from the raw material selection stage to reduce the hidden dangers of pollutants; for difficult raw materials, alternative products should be sought, or management should be strengthened to limit the use; Adopt cleaner production technology to reduce the generation of waste water in the production process.

Secondly, for the wastewater that has been generated, it is necessary to select an appropriate process according to the characteristics and types of industrial wastewater, determine the best process parameters and operation management mode, and treat the wastewater to meet the discharge standards. At the same time, the use of classified collection and separate treatment, and strengthening the recycling of wastewater can greatly reduce the technical difficulty and operational management difficulty of wastewater treatment, and reduce pollution.

Finally, strengthen the supervision of industrial wastewater. Relevant departments have tightened the examination and approval system, strengthened law enforcement, and controlled new pollution sources; refined legislation to clarify property rights, compensation and economic responsibilities; centralized sewage treatment, established unified treatment equipment, and promoted the implementation of the sewage charging system.
