1, water can't flow normally:
At this time, it is necessary to check whether the connecting pipes of contact oxidation pool, sedimentation pool, disinfection pool and sludge pool of sewage treatment equipment are blocked. Usually, the blockages are exfoliated biofilm and damaged elastic three-dimensional filler).
2. The aeration of the contact oxidation tank is uneven:
In this case, check whether the outlet valve of aeration fan of sewage treatment equipment is in normal position and whether the aeration head is damaged.
3. The film-forming 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 into the tank. If the above situation is normal, add appropriate nutrients, such as sugar and urea, to the pond.
4, the effluent quality is not up to standard:
Excessive water inflow will lead to uneven aeration or long-term shutdown of contact oxidation tank. At this point, the biofilm must be re-cultured. Too much sludge in the sedimentation tank of sewage treatment equipment will lead to the shutdown of disinfection equipment and the effluent cannot be disinfected for a long time.
5, automatic control failure:
Check whether the power supply of automatic control cabinet of sewage treatment equipment is normal. Check whether the supporting lifting pump and aeration fan are damaged. Sometimes the current is too large, and the circuit breaker automatically turns off.
