What should I do if the aerobic tank in the MBBR Mini Plant is abnormal?
Biochemical treatment is based on the different requirements of microbial growth on the oxygen environment, that is, the oxygen pool is divided into aerobic biochemical treatment and anoxic biochemical treatment. Generally, aerobic biochemical treatment is used more in the market. If sewage treatment What should I do if the aerobic pool of the equipment is abnormal?
1. Why is the dissolved oxygen in the aerobic pool insufficient?
The blower fails to stop running or the pressure of the blower is not enough;
Due to the large amount of suspended solids in the effluent of the anaerobic tank, a large amount of dissolved oxygen is consumed after entering the aerobic tank;
The rapid increase in the concentration of sludge in aerobic pools or the aging of sludge will lead to an increase in oxygen consumption;
The sudden increase of COD in the effluent of the anaerobic tank or the sudden increase of the influent will cause the load of the aerobic tank to increase;
2. Why do a lot of bubbles appear in the aerobic pool
Raw water contains a lot of surfactant components, and the foam is generally white;
A large amount of lipid substances or microorganisms are produced in the reproduction of microorganisms;
The tiny air bubbles generated by the newly installed aeration head will only be affected in the short term;
