Check the lubrication of the bearings and the tightening of the bearing bolts in the buried sewage treatment equipment . Check that the bolts and nuts on the base and the coupling on the fan base are tight. Check that the axial seal packing (packing) is under pressure, and check that the pipeline to the water seal ring in the shaft seal is well connected.
Maintenance tools and materials. When the local buried sewage treatment equipment has insufficient water or limited water capacity, it should negotiate with relevant departments to adjust the plan to obtain a normal continuous trial operation agreement. When testing a mine pump, it is particularly desirable to prevent floating matter in the water tank of the buried sewage treatment equipment from being sucked into the pump to damage the impeller.
Check each auxiliary pressure gauge for large wastewater treatment equipment . Safety devices and electronic controls should be sensitive, accurate and reliable. The car should be flexible and free from abnormalities.
Biofilm method is mainly used in the main process of underground sewage treatment equipment. At present, underground sewage treatment equipment has gradually developed into contact oxidation process and MBR process. In particular, the MBR process has become a research hotspot in recent years. Compared with the contact oxidation method, the MBR process has a better treatment effect and a lower residual sludge rate. The effluent water quality can meet the urban sewage treatment and discharge standards.
The effect of biofilm formation is not obvious: at this time, the aeration of the buried sewage treatment equipment should be checked for uneven failure. If the explosion is normal, consider adding some nutrients to the microorganisms; uneven aeration: In this case, first check whether the valve of the aeration fan is abnormal and the aeration head is damaged.
Unqualified effluent water quality: If the water quality of the underground sewage treatment equipment is unqualified, check whether the water intake is too large, whether the aeration is uneven, whether the sludge in the sedimentation tank is cleaned, whether the disinfection equipment is operating normally, and whether the sewage is disinfection.
