However, domestic sewage treatment equipment is generally buried underground, so if the sewage discharge does not meet the standards, the equipment needs to be tested, and the program may be slightly more complicated. What are the reasons for the non compliant discharge of domestic sewage treatment equipment?

Domestic sewage treatment equipment

The domestic sewage treatment equipment consists of the main equipment, fan, sewage lift pump, sludge pump, booster pump, chlorine dioxide generator, aerobic tank, anoxic tank, sedimentation tank, disinfection tank, etc. It is commonly used for surface integrated domestic sewage treatment equipment, which is generally composed of SBR, A/O and A2/O, biological contact oxidation method and other processes.

1. Before purchasing domestic sewage treatment equipment, one should have a general understanding of the water quality of the sewage and choose the sewage treatment process based on the water quality. ?

2. The equipment is equipped with aerobic and anoxic tanks for microbial growth, but the sewage treatment equipment is located underground, which is not conducive to the insulation of the equipment in winter.

3. If the domestic sewage treatment equipment cannot discharge normally, it is necessary to check the sedimentation tank, disinfection tank, contact oxidation tank, sludge tank connection pipe blockage and other reasons.

4. When the aeration in the contact aeration tank is uneven, it is possible to check whether the aeration head is damaged or whether the outlet valve of the aeration fan is misaligned.

5. If the dosage of chemicals in the equipment is not sufficient, it can also lead to substandard sewage discharge.

6. The pH value of the incoming water also has an impact on the discharge of sewage. If the pH value is too high, the pH control of the reaction tank will be unstable, causing turbidity in the sedimentation tank of the equipment.
