What are the common problems with sewage treatment equipment

Common problems with sewage treatment equipment:

1. Equipment cannot discharge water normally: Check if the connecting pipes of the contact oxidation tank, sedimentation tank, disinfection tank, and sludge tank are blocked (the blocking objects are usually detached biofilms and damaged elastic three-dimensional fillers).

2. Uneven aeration in the contact oxidation tank: Check whether the outlet valve of the aeration fan is in the normal position and whether the aeration head is damaged.

3. Although the integrated sewage treatment equipment is a relatively sturdy type of equipment, due to long-term use in sewage treatment, the sewage contains a large amount of active chemical substances. In some special cases, rust can grow on the pool wall. In addition, unreasonable use can also lead to equipment cracking, and even abnormal situations, making leakage easy to occur.

4. Although highly adaptable to the environment, low winter temperatures are not conducive to insulation and maintenance.

5. Improper sewage treatment operations may consume too much energy, and some sewage treatment processes and methods may meet water treatment standards.

Maintenance methods for sewage treatment equipment:

1、 Check whether the inlet and return pumps of the domestic sewage treatment equipment freeze during work every day, including lubrication and oiling of the water pump, tightness of the packing, sealing of the bottom valve, and oil filling of the air compressor.

2、 Check if the air filter of the air compressor has frozen to determine whether the air compressor is operating normally and whether there are any noise or heating phenomena.

3、 Check the transmission part and scraper of the slag scraper to see if they become hard or broken in cold conditions to avoid affecting their use.

4、 Pay attention to the mixing and storage tank of the coagulant to avoid freezing, and frequently conduct small sample tests.

5、 Inspect the valve pipelines of each equipment to avoid blockage, and place them in the "on" or "off" positions as required.

6、 When stopping the machine, the water must be drained clean to avoid freezing and blockage.
