Ao contact tank for domestic sewage treatment and reuse Among the influencing factors of An/O biological phosphorus removal process, influent COD/TP and BOD load of biochemical reaction system are key. The test results show that the larger the COD/TP is, the more anaerobic phosphorus release is, which is more conducive to phosphorus removal. The amount of anaerobic phosphorus release is a function of the amount of absorbed COD; Moreover, the change of influent COD/TP will not significantly affect the removal of system COD -
