[0021] Combine figure 1 , 2 , 3 Detailed description of the embodiments of the present invention
[0022] (1) Domestic sewage enters the (A / A / O)-SBR reactor (2) from the raw water tank (1) via the raw water pump (4). After the water inflow is completed, the agitator (12) starts to stir, and DPAOS uses the raw water The VFAs synthesize the internal carbon source PHA, release phosphorus at the same time, control ORP=-30~-240mv, DO≤0.2mg / L, water filling ratio 0.2, reaction time 1.5-2h, most of COD is removed in this process.
[0023] (2) After the anaerobic reaction is completed, the reflux nitrification liquid from the N-SBR reactor (3) is injected through the reflux pump (6). The nitrate nitrogen contained in the DPAOs is used as the electron acceptor, and the nitrate is stored in the anaerobic stage. PHA is used as an electron donor to undergo anoxic denitrification and dephosphorization reaction. Control ORP=-90~-210mv, DO≤0.2mg / L, water filling ratio 0.4, reaction time 4-5h, mos...
