Method for removing total nitrogen and total phosphorus in multi-raw material alcohol wastewater

The invention discloses a method for removing total nitrogen and total phosphorus in multi-raw material alcohol wastewater. The method comprises the following steps: 5.5-6.5 kg/t of a sewage polyferric sulfate adsorbent and 50-60 ppm of a polyacrylamide flocculating agent are sequentially added to a multi-raw material alcohol wastewater clear liquid, solid-liquid separation is carried out by using an inclined plate settler, the obtained solid enters a plate-and-frame filter press and is dehydrated, and the obtained waste liquid enters a clear liquid tank and then enters an alcohol wastewater treatment system. The total nitrogen removal rate of the waste liquid is 47.54-52.84%, and the total phosphorus removal rate of the waste liquid is 44.08-58.02%. The method solves the qualification technical problem of key indexes of total nitrogen and total phosphorus in the waste liquid in the fermented alcohol industry, provides a multi-raw material alcohol wastewater treatment method for large alcohol factories, and h
