◆Process introduction

The source and composition of sewage discharged by medical institutions are very complicated. The sewage contains a large number of infectious bacteria, viruses, chemical agents and other harmful substances, which are very harmful and infectious. Especially the sewage discharged from the infectious disease area, if it enters the urban sewage pipes or environmental water bodies without strict harmlessness, it will cause water pollution and outbreaks of infectious diseases, which will seriously endanger people's health.

At present, the treatment process of medical wastewater mainly consists of one-stage precipitation disinfection treatment and two-stage biochemical disinfection treatment. The specific treatment process can be selected according to the effluent requirements. When the treated wastewater can be discharged into the municipal sewage official website, the primary treatment is adopted, and when direct discharge is required, the secondary treatment process is adopted.
