Embodiment Construction
[0031] figure 1 Shown, is a kind of livestock and poultry breeding sewage treatment process, comprises the following steps:
[0032]1) Sewage pretreatment: the aquaculture sewage is collected by the channel and flows to the grid well by itself, after removing debris through the grid well, it flows to the pH adjustment tank by itself, and the effluent adjusted by the pH adjustment tank flows to the wastewater adjustment tank by itself, and passes through the wastewater adjustment tank Complete the adjustment of water quality and water volume, and then send the effluent to the air flotation tank; the effluent after removing scum in the air flotation tank flows to the intermediate pool for water volume adjustment;
[0033] 2) Sewage biochemical treatment: A2 / O2 internal circulation biological denitrification and phosphorus removal process combined with contact oxidation process; that is, the effluent in the intermediate pool enters the UASB anaerobic pool from the bottom, and flo...
