3 Terms and definitions

The following terms and definitions defined in GB 50014 apply to this document. For ease of use, GB 50014 is repeatedly listed below Some terms and definitions in. 3.1 Post-treatment of domestic seawater Use physical, chemical, biological or other methods to degrade and remove pollutants in towns or domestic sewage containing large domestic seawater, The process of purification. 3.2 Post-treatment of domestic seawater by activated sludge process Activated sludge method is used to treat urban sewage or domestic sewage containing large domestic seawater to make it meet the discharge standard. The The technology is to form salt-tolerant activated sludge in a suspended state through salt-tolerant domestication and continuous mixed culture of various microbial groups in sewage. Using the biological function of salt-tolerant activated sludge to decompose and remove organic pollutants in sewage containing large domestic seawater, and then make the sludge and water Most of the sludge is returned to the biological reaction tank, and the excess part is discharged out of the activated sludge system as excess sludge. 3.3 Salt-tolerant activated sludge Activated sludge that has undergone salt tolerance domestication and has the ability to tolerate the salt in the sewage. 3.4 Salt-resistant domestication The process of gradually increasing the salinity of sewage to adapt the microorganisms in the activated sludge to the saline environment. 3.5 Adjustingtank A structure used to adjust the quality of incoming and outgoing water (including salt content) and water volume. ......
