Effect of solid-liquid separator in the separation of livestock and poultry manure

Mar 21, 2020

The solid-liquid separator can be used for the separation of livestock and poultry manure. The solid-liquid separation measures before the pig manure can not only solve the problem of pig manure sedimentation in the biogas digester, greatly enhance the processing capacity of the biogas digester, but also greatly reduce the biogas digester. And construction area of biochemical pool.

1) The volume of the old biogas digester originally built by the breeder is too small, and the sewage is discharged into the pond for too short a time, which leads to excessive discharge of sewage concentration. Then, the sewage is treated with a solid-liquid separator of livestock and poultry before entering the pond. Reduce the content of sewage COD, BOD, and reduce the operation load of biogas digesters, so as to reduce and reduce sewage discharge;

2) The use of solid-liquid separator can transform the feces 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 full digestion time. The active bacteria in the tank can reproduce more vigorously and the gas production f is higher. The content of gas methane is naturally high, and the gas purity is high, and it is naturally overcome. Solve the problem of abnormal operation of biogas generators;

3) The sewage treated by the solid-liquid separator enters the biogas digester. Can effectively solve the crusting phenomenon of biogas digesters, eliminating the work of cleaning biogas residues;

4) The use of livestock and poultry manure solid-liquid separators can reduce the investment in the construction of biogas digesters, such as: aquaculture or slaughterhouses that discharge 100 tons of sewage per day. If a matched livestock and poultry manure solid-liquid separator is used in advance, it can reduce 300 cubic meters of anaerobic pond construction investment, because the concentration of sewage mixed into the pond is too high. The anaerobic time needs to be extended accordingly, so the farm discharges 100 tons of sewage per day. No solid-liquid separator for livestock and poultry manure treatment if. Then invest 1000-1200 cubic meters of anaerobic tank. If you use livestock and poultry manure solid-liquid separator, it can reduce the construction of 300-400 cubic meters.
