How to solve the problem of laboratory sewage treatment equipment?

Author: Source: Time: 2019-12-11 Category: Technical Articles

With the increase of people's awareness of environmental protection, the level of concern over water pollution has reached unprecedented levels, and the sewage treatment industry has developed rapidly. Laboratory sewage treatment equipment and machines are becoming more and more widely used. Since the equipment will have problems in use and cause it to not work properly, this is the only way for people with no idea to go crazy. Today Xiaobian Let me tell you how to solve the problem that the sewage treatment equipment does not work in the process of using the sewage treatment equipment. Specifically, we analyzed the following five situations:

First, the sewage treatment equipment can not normally produce water

Check whether the communication pipelines of the oxidation pond, sedimentation pond, disinfection pond, and sludge pond are blocked (the blockage is generally the falling biofilm and damaged elastic three-dimensional filler).

Second, uneven aeration of contact oxidation tank

Check whether the outlet valve of the aeration fan is in the normal position and whether the aeration head is damaged.

Third, the biological membrane is not effective

Check whether the aeration in the contact oxidation tank is uniform, and whether the sludge from the secondary sedimentation tank is pumped to the tank. If the above conditions are normal, add an appropriate amount of nutrients (sugar, urea, etc.) to the tank.

Fourth, the effluent quality of sewage treatment equipment does not meet the standards

Excessive water inflow; uneven aeration in the contact oxidation tank or long-term outage (re-cultivation of biofilm at this time); excessive sludge in the sedimentation tank (to remove sludge); outage of the disinfection device and long-term outflow disinfection.

V. Failure of automatic control of sewage treatment equipment

Check whether the power of the automatic control cabinet is normal, and check whether the supporting lift pump and aeration fan are damaged (at this time, an excessive current can be formed, and the disconnect switch is automatically disconnected).
