If we use underground sewage treatment equipment improperly, it may suddenly shut down. So how should we deal with it? Zhongkebeite will introduce to you:
1. Underground sewage treatment equipment cannot discharge water normally: Check if the connecting pipes between the contact oxidation tank, sedimentation tank, disinfection tank, and sludge tank are blocked.
2. Uneven aeration in the contact oxidation tank: Check if the outlet valve of the aeration fan is in the normal position and if the aeration head is damaged.
3. The biofilm attachment effect is not obvious: check whether the aeration in the contact oxidation tank is uniform, and whether the sludge in the secondary sedimentation tank is pumped to the tank. If the above conditions are normal, add an appropriate amount of nutrients to the tank.
4. The effluent quality of the sewage treatment equipment does not meet the standard: the inflow is too large. Uneven aeration or prolonged shutdown of the contact oxidation tank requires re cultivation of the biofilm; If there is too much sludge in the sedimentation tank, it is necessary to remove the sludge, stop the disinfection device, and do not disinfect the effluent.
5. The automatic control of the buried sewage treatment equipment has malfunctioned: check whether the power supply of the automatic control cabinet is normal, and check whether the supporting lifting pump and aeration fan are damaged
