The school sewage is similar to our general urban sewage, which mainly comes from four parts: toilet water, washing water, kitchen water, naturally generated rainwater or snow water. Of course, some schools also involve special laboratory sewage. Generally speaking, school sewage contains a lot of organic pollutants and suspended particulate pollutants.

According to the above sewage sources, school sewage treatment mainly pays attention to the following points:

First, the canteen sewage should be treated with oil separation. The effluent from the school canteen is a special part of the school sewage. It needs to be treated by oil separation at the front end of the school sewage, and then treated by septic tank and regulating tank, so as to better ensure the discharge standard.

Second, sewage equipment should be selected with small floor space, simple operation, control, maintenance and management, and high degree of automation. Generally speaking, schools don't have much space for sewage treatment stations, so try to choose equipment with small space; Access personnel are strictly controlled, and there are generally no professional control personnel, so we should also choose equipment with simple maintenance and high automation.

Third, the sewage equipment should pay attention to sealing and quietness. Because the school will involve many children in lower grades, the sewage equipment needs to be sealed to prevent children from entering the venue by mistake and causing unnecessary safety problems. At the same time, in order to ensure the teaching quality of the school, the sewage equipment should be low noise.

The school is a typical crowded place. When choosing equipment, we must put safety first, and remember not to be greedy for petty gain to prevent accidents.
