The Purpose And Importance Of Sewage Disinfection

After secondary treatment, the water quality of urban sewage has been improved, and the bacterial content has been greatly reduced, but the absolute value of bacteria is still considerable, and there is the possibility of pathogenic bacteria. Therefore, disinfection treatment should be carried out before water discharge or irrigation. Sewage disinfection should be continuously operated, especially in the upstream of urban water sources, tourist areas, summer or epidemic seasons.
