The main role of solid-liquid separator in life is:
1) The volume of the old biogas digester originally built by the breeder is too small, and the drainage time of sewage entering the pond is too short, which leads to the excessive discharge of sewage concentration, so the solid-liquid separator of livestock and poultry manure should be used to treat the sewage before entering the pond. It can be useful Reduce the content of sewage COD and BOD, reduce the operation load of the biogas digester, and then reduce the discharge of sewage;
2) The solid-liquid separator can be used to transform the manure in fresh sewage into valuable fish feed or organic fertilizer. The separated sewage enters the biogas tank intermittently, so that the anaerobic tank can have a sufficient time for digestion. The active bacteria in the tank can reproduce more vigorously, and the gas production f can be higher. The content of gas methane is naturally high, and the purity is high, and it is naturally defeated. Deal with the problem of abnormal operation of biogas generators;
3) The sewage treated by the solid-liquid separator enters the biogas digester. Can effectively deal with the crusting phenomenon of biogas digesters, eliminating the need to clean up biogas residues;
4) The use of livestock and poultry manure solid-liquid separators can reduce the production cost of biogas digesters, for example: a breeding or slaughtering plant that discharges 100 tons of sewage per day. 300 cubic meters of anaerobic tank production investment, because the concentration of manure and sewage mixed into the tank is too high. Anaerobic time also requires a corresponding extension of time, so the daily discharge of 100 tons of sewage in the breeding farm. Do not use livestock and poultry manure solid-liquid separator treatment if. Then invest 1000-1200 cubic meters of anaerobic tank. It is assumed that the solid-liquid separator of animal manure can reduce the production of 300-400 cubic meters.
