Ecological utilization method for purifying rural household sewage and sewage generated by aquatic bird breeding

The invention provides an ecological utilization method for purifying the rural household sewage and sewage generated by aquatic bird breeding. The method comprises the following steps: preprocessing rural household sewage and sewage generated by aquatic bird breeding, introducing preprocessed sewage into an ammonification and phosphorization biological tank, wherein the ammonification and phosphorization biological tank contains sludge, which comprises bacillus and pseudomonas, and the microbes can convert the organic nitrogen and organic phosphorous in sewage into ammonia nitrogen and inorganic phosphorous; introducing the sewage into a phytase mixing tank, processing sewage in the phytase mixing tank; then introducing the sewage into a ditch, wherein in the ditch, optical fertilizer type aquatic vegetables are planted in the ditch, a greenhouse is arranged over the ditch, the greenhouse is covered by a light conversion membrane, which can absorb the UV light in sunlight and convert UV light into blue light
