(1) A pre-denitration tank: mixing part of the raw sewage entering the equipment with the sludge returned from the secondary sedimentation tank, and carrying out pretreatment to remove nitrate in the returned sludge.
(2) An anaerobic tank: mixing the residual raw sewage entering the equipment with the pre-denitrated return sludge, wherein the main function is to release phosphorus and simultaneously ammoniate partial organic matters.
(3) An anoxic tank: its main function is denitrification.
(4) An aerobic tank: this is the core segment of the overall process, where the role is multifunctional, removal of organic contaminants, nitrification and phosphorus absorption, etc. are all performed.
(5) A secondary sedimentation tank: the function is mud-water separation, one part of separated sludge flows back to the pre-denitration pool, and the rest part of sludge is discharged.
The above-mentioned sewage treatment apparatus using the AAO process has the following problems.
1. Raw sewage entering the sewage treatment device is generally pressurized by a water pump and then is distributed to the pre-denitration tank and the anaerobic tank through pipeline bifurcation, and the bifurcated pipeline is easy to block.
2. Water is fed through the branching configuration of the pipelines, the proportion is not easy to control, so that the amount of raw sewage respectively entering the pre-denitration tank and the anaerobic tank is unreasonable, and the treatment effect is influenced.
