What will be done after advanced treatment of stainless steel muffler manufacturers

The design of muffler for discharge water quality of chemical construction project must meet the following requirements:

1. The wastewater discharged into the sewage treatment plant of the chemical industry park shall meet the requirements of the current national and industrial standards on the indirect emission limit. For the pollutants without the limit value, the enterprise shall negotiate with the sewage treatment plant of the chemical industry park to determine the take over standard;

Article 2 the sewage discharged into the urban sewage treatment plant shall meet the requirements of GB / t31962 water quality standard for sewage discharged into urban sewers and meet the requirements for inflow of urban sewage treatment plant on the premise of meeting the requirements of current national and industrial discharge standards;

3. The wastewater directly discharged into the surface water body should meet the current national, industrial and local discharge standards.

Article 4 the radioactive activities of waste water containing radioactive substances shall meet the requirements of gb8703.

Comply with the environmental impact report, approval documents and other requirements stipulated by local environmental protection department.

The waste water discharge outlet of chemical industry construction project shall not be set in muffler pipe muffler 1. Water source protection area, National Nature Reserve, marine special protection area and marine special protection area;

Secondly, water body and bathing pool in scenic area;

Main aquaculture waters, habitat of rare aquatic organisms, spawning ground of fish and shrimp, feeding ground of larva, etc;

Fourth, waters with special economic and cultural value;

Within a certain water area upstream of water intake of No.5 plant, the specific scope of muffler company is determined by environmental assessment. The system of "one plant, one pipe" should be adopted for the general sewage discharge outlet of chemical industry construction project. In the chemical construction project, concentrated brine treatment and evaporation crystallization device should be equipped with concentrated brine temporary storage tank.
