Domestic sewage treatment equipment
The removal of organic pollutants and ammonia nitrogen by domestic sewage treatment equipment mainly depends on the AO biological treatment process in the equipment. The following domestic sewage treatment equipment manufacturers introduce it to us and hope to help us:
What is the working principle of domestic sewage treatment equipment?
Domestic sewage treatment equipment
It is at level A. Due to the high concentration of organic matter in the sewage, the microorganisms are in anoxic state. At this moment, the microorganisms are facultative microorganisms. Therefore, the level A pool not only has a certain function of removing organic matter, reduces the organic load of subsequent aerobic ponds, and reduces the concentration of organic matter. However, a certain amount of organics and higher NH3-N are still present. In order to further oxidize and differentiate the organic matter, the nitrification effect can be smoothly carried out under the carbonization effect, and an aerobic biological contact oxidation pond with a lower organic load is set in the O level. Aerobic microorganisms and auto-aerobic bacteria (nitrifying bacteria) are mainly present in the O-level pool.

During this time, aerobic microorganisms differentiate organic matter into CO2 and H2O; autotrophic bacteria (nitrifying bacteria) use inorganic carbon produced by organic matter differentiation or CO2 in the air as a nutrient source. The operating principle of the equipment converts NH3-N in sewage into NO The effluent of the -2-N and O-level pools is returned to the A-level pool to provide an electron acceptor for the A-level pool. After denitrification, nitrogen pollution is finally eliminated.
