The current pollutant emission standards for the petrochemical industry, GB31571-2015, set a standard of 60PPm for wastewater discharged directly from existing chemical plants. Is it difficult for various provinces and cities to implement these standards? How to deal with it?

Does 60PPM refer to COD?

60 ppm COD is acceptable; it’s not completely impossible. It just requires investing in better equipment, improving the precision of the processing, and reducing randomness in operations
