The actual use proves this The direct biogas cultivation effect is not ideal. Because the untreated manure water enters the biogas digester, which greatly increases the organic load per unit volume of the digester, so the volume of the digester must be increased a lot. Due to the long-term use of the biogas digester, a large amount of residue is left after fermentation, which causes the digester to be blocked and the capacity is reduced, which makes the digester unusable. Therefore, solid-liquid separation measures should be carried out before pig manure, which can not only solve the problem of pig manure sedimentation in the biogas tank, greatly enhance the processing capacity of the biogas tank, but also greatly reduce the construction area of the biogas tank and biochemical tank. The construction investment and land use area of environmental protection treatment are saved, and the separated pig manure can also be directly used as a raw material for fruit tree and forest fertilization and as organic fertilizer.

The solid-liquid separator can separate the solid and liquid of pig manure, which can not only solve the problem of pig manure sedimentation in the biogas tank, greatly enhance the processing capacity of the biogas tank, but also greatly reduce the construction area of the biogas tank and biochemical tank. widely used.
