Embodiment 1
[0038] The processing of embodiment 1 livestock and poultry farm excrement and urine
[0039] (1) The original high-ammonia-nitrogen wastewater is divided into mainstream wastewater and side-stream wastewater, and the flow ratio of the two is 2.5;
[0040] (2) The mainstream wastewater enters the short-range nitrification reactor 1 through the mainstream wastewater inlet pump 1.1 for short-range nitrification reaction. In the short-range nitrification reactor, non-accurate continuous timing aeration is adopted, and the hydraulic retention time is controlled for 6 hours. The produced nitrate nitrogen and nitrous The nitrogenous wastewater is discharged through the outlet pump 1.2, and forms mixed wastewater with the side stream wastewater and the incoming water of the circulating water inlet area 3.1, and enters the high-efficiency denitrification anaerobic reactor 2 through the water inlet 2.1. The denitrifying bacteria in the liquid phase in the interior use the organic matte...
