How is biofilm cultivated in underground integrated sewage equipment? Next, let’s give a brief introduction:

       1, sewage enters the equipment;

2, start the fan, and the oxygenation amount of the sludge pump and fan is reduced to about half of the normal oxygenation amount;

3. Observe the filling condition in the aerobic tank every day. If there is an orange-yellow or orange-black layer on the filling, Sticky substance, that is, the biofilm has been cultured, and the culture interval is generally10—25day completed;

4, the temperature is generally around Celsius15℃—25℃suitable;

5, If the concentration of raw sewage is too low, cultivate undergroundIntegrated sewage equipmentThe biofilm takes too long. If necessary, some nutrients should be added, mainly feces or other nutrients;

6,PHThe value needs to be guaranteed at6.5—8.5In between, the raw sewage must be guaranteed to reach a biodegradable state;

7,处理工业污水，Integrated sewage equipment开始调试前要以生活污水为主，待生物膜培养好后，少量的不断进其它工业污水，使生物膜适应工业污水生长，即调试正常开始。
