Embodiment Construction

[0020] A fully automatic and efficient device for treating sewage and feces and producing biogas according to the present invention includes a U-shaped solid-liquid separation pond, a biogas pond, a biogas residue pond, a biogas slurry pond and a reclaimed water pond.

[0021]The solid-liquid separation tank of the present invention includes a coarse slag pool, a fine slag pool, and a membrane filtration tank. The coarse slag pool and the fine slag pool surround the membrane filtration tank in a U shape, and the coarse slag pool passes through the first channel The grid filter is connected with the fine slag tank, and the fine slag tank is connected with the membrane filter tank through the second grid filter, and the upper part of the membrane filter tank is provided with a suction pipe, and the membrane filter tank is connected with the reclaimed water tank through the suction pipe. Sewage and livestock manure first enter the coarse residue pond from the feed port of the coar...

Abstract

The invention discloses a full-automatic efficient sewage and excrement treating and biogas generating device, and belongs to the technical field of sewage and livestock and poultry excrement treatment. The full-automatic efficient sewage and excrement treating and biogas generating device comprises a solid-liquid separating tank, a biogas tank (8) and a biogas residue tank (13) and is characterized in that the solid-liquid separating tank comprises a coarse residue tank (15), a fine residue tank (16), a membrane filtering tank (14) and a reclaimed water tank (1), and the coarse residue tank (15) and the fine residue tank (16) are communicated with the biogas tank (8) through siphons (7); a metal heat absorbing plate (19) is laid on a gabled roof, a light-transmitting panel (21) is arranged above the metal heat absorbing plate (19), the upper middle of the wall of the biogas residue tank (13) is communicated with the biogas tank (8) through a biogas residue discharge pipe (12), the upper portion of the biogas residue tank (13) is communicated with a biogas slurry tank (10) through a grid filtering net (11), and a biogas slurry tank siphon introduced into the biogas tank (8) is arranged in the biogas slurry tank (10). Biogas is fast generated by sewage and livestock and poultry excrement in the modes of high-temperature fermentation and automatic stirring.

Description

technical field [0001] The invention belongs to the technical field of sewage and livestock and poultry excrement treatment, and in particular relates to a device for fully automatic and efficient treatment of sewage and excrement and biogas production. Background technique [0002] my country is a large agricultural country with a wide distribution of agricultural waste resources. Among them, the annual output of agricultural straw exceeds 600 million tons, and the straw that can be used as energy is about 350 million tons, which is equivalent to about 150 million tons of standard coal. Industrial wastewater and waste from poultry and livestock farms can theoretically produce nearly 80 billion cubic meters of methane, equivalent to 57 million tons of standard coal. Biogas has become an important part of rural energy in my country. It can not only solve some energy problems in rural areas, but also integrate aquaculture and planting into one organically, forming green agricu...
