What Is an Emissions Cap?
Discharge concentration limitation, also known as water pollutant discharge concentration control, is a management system that limits wastewater discharge from wastewater according to water pollutant discharge concentration.

- Discharge concentration limitation, also known as water pollutant discharge concentration control, is a management system that limits wastewater discharge from wastewater according to water pollutant discharge concentration. This restriction method is mainly achieved by specifying a reasonable maximum allowable emission concentration standard of pollutants. In 1988, China issued the "Integrated Sewage Discharge Standard", which stipulates that the nature of discharged pollutants can be divided into two categories: The first type of pollutants refers to those who can accumulate in the environment or animals and plants and have a long-term impact on human health (including Total mercury, alkylmercury, total cadmium, total chromium, hexachromium, total arsenic, total lead, total nickel, and benzo (a) nine species), sewage of such harmful pollutants, regardless of industry and sewage discharge Method, regardless of the functional category of the receiving water body, must reach the maximum allowable discharge concentration at the outlet of the workshop or workshop processing facility; the second category of pollutants refers to substances whose long-term impact is less than the first category of pollutants, and its pollutant discharge unit The discharge outlets should be according to the different destinations of sewage discharge, and implement the maximum allowable discharge concentration standards of Class 1, 2 and 3 pollutants respectively (the level 1 standard for sewage discharged in Class III surface waters; Sewage implements second-level standards; third-level standards are implemented for sewage discharged into urban sewers and entering secondary sewage treatment plants for biological treatment; for surface waters of Class I and II, no new construction is required Dirty mouth, it should ensure that the sewage water quality comply with water quality standards use). For some industries, corresponding maximum allowable emission concentrations of pollutants have also been formulated according to different industries, different processes, different enterprise properties and different scales.
