Multi-stage circulation treatment device for sewage of pigsty

Abstract

The invention relates to the field of treatment of culture sewage, and particularly relates to a multi-stage circulation treatment device for sewage of a pigsty. The multi-stage circulation treatmentdevice comprises a motor, a machine frame, a sewage treatment roller pair and a next-stage sewage treatment tank, wherein the sewage treatment roller pair is rotationally connected with the machine frame under a blowdown port of the pigsty; the sewage treatment tank is arranged under the sewage treatment roller pair; the surface of each of the sewage treatment roller pair is provided with two symmetric spiral grooves along the axial direction in a tangential way; the interior of each of the two spiral groove is respectively glidingly connected with a slide block; each slide block is glidinglyconnected with the machine frame; the top part of each slide block is respectively connected with a crushing part, and each slide block can be slide along the length direction of the corresponding crushing part in a reciprocating way; one end of each crushing part above of each the slide blocks in the two spiral grooves is hinged together, and the crushing parts at the hinged side are higher thanthe crushing parts at the other side. The multi-stage circulation treatment device has the advantages that the solid suspensions and the like can be crushed, and the sewage can be circulated for subsequent recycling.

Description

technical field [0001] The invention relates to the field of aquaculture sewage treatment. Background technique [0002] Under the background of generally encouraging the expansion of breeding production in rural areas, my country's livestock and poultry breeding industry has developed vigorously, showing a trend of industrialization, scale and regionalization in recent years. Due to the large amount of wastewater discharged from large-scale livestock and poultry farms, the high concentration of pollutants, and the long-term lack of attention and management in my country, it has become one of the main sources of pollution in most regions and watersheds in my country, causing serious environmental pollution and a large amount of nitrogen and phosphorus every year. Resource loss and waste. Therefore, how to deal with farm sewage has become a major problem that plagues the development of enterprises. [0003] Farm sewage mainly includes urine, some feces and flushing water, wh...
