Domestic wastewater treatment is the top priority of current environmental treatment. The use of municipal wastewater recycling equipment is an effective way to treat sewage quickly and effectively, and the selection of municipal wastewater recycling equipment is also very important. However, the maintenance of municipal wastewater recycling equipment is relatively simple. Nevertheless, in order to extend the service life of the equipment, we should also set up a regular maintenance system. Today, we are going to share with you the common failure of municipal wastewater recycling equipment.
1. Abnormal water
Check contact oxidation tank, sedimentation tank, disinfection tank, sludge tank communication pipeline is blocked.
2, contact aeration tank aeration is not uniform
Check whether the outlet valve of aerator fan is in normal position and whether the aerator head is damaged.
3. Biofilm contact effect is not obvious
Check whether the aeration of contact oxidation tank is uniform and whether the second sedimentation tank pump is pumped into the tank. If the above conditions are normal, an appropriate amount of nutrients can be added to the pool.
4. The effluent quality is not up to the standard
Contact oxidation tank aeration is not uniform or long-term shutdown (this must be re-cultured biofilm), excessive sedimentation tank sludge. Disinfecting equipment stops running, disinfecting for a long time.
5, automatic control failure
Check whether the power supply of the automatic control cabinet is normal, check whether the supporting lift pump and aeration fan are damaged.
