And part of organic carbon source and NH-N are used for synthesizing new cell substances, so that the A-level pool not only has a certain organic matter removing function and reduces the organic load of a subsequent aerobic pool so as to be beneficial to the digestion, but also completes the reverse digestion function by relying on the higher-concentration organic matters existing in the raw water, finally eliminates the nitrogen eutrophication pollution, and because the concentration of the organic matters is greatly reduced in the O level, a certain amount of organic matters and higher NH-N still exist. In order to further oxidize and decompose organic matters and simultaneously ensure that the digestion can be smoothly carried out under the condition that the carbonization is finished, an aerobic biological contact oxidation pond with lower organic load is arranged at an O level, aerobic microorganisms and self-aerobic bacteria (digestive bacteria) mainly exist in the O level pond, wherein the aerobic microorganisms decompose the organic matters into CO2 and H2O, and the self-aerobic bacteria (digestive bacteria) use inorganic carbon generated by the decomposition of the organic matters or CO2 in the air as a nutrient source to convert NH-N in the sewage into NO-N. And the effluent part of the O-level pool is refluxed to the A-level pool by a sludge reflux pump to provide an electron acceptor for the A-level pool, and nitrogen pollution is finally eliminated through the reverse digestion.
