Embodiment Construction
[0031] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0032] (1) Sewage enters the anaerobic zone (1.1) of the AAO reactor (1) from the inlet pump (1.6), and at the same time, the return sludge from the secondary settling tank (2) flows back to the anaerobic zone through the sludge return pump (2.1) , in the anaerobic zone, the denitrifying phosphorus-removing bacteria DPAOs absorb the COD in the raw water to synthesize the internal carbon source PHAs, and at the same time release the phosphorus in the body to the outside world, and control the hydraulic retention time HRT in the anaerobic zone to 1-2h;
[0033] (2) Sewage enters the anoxic zone (1.2) from the anaerobic zone (1.1), and at the same time, the effluent from the biological aerated filter BAF (3) is returned from the final pool (3.2) to the anoxic zone by the nitrifying liquid return pump (3.12) In the anoxic zone, the denitrifying phosphorus accumul...
