Solid-liquid separation device for domestic sewage

Abstract

The invention provides a solid-liquid separation device for domestic sewage, which relates to the field of sewage treatment. The solid-liquid separation device for domestic sewage comprises a separation box, a filtering pipeline is fixedly connected to the top end of the separation box, a baffle is arranged on the outer wall of the filtering pipeline, a feeding hopper is fixedly connected to the top end of the filtering pipeline, and a water spraying pipe is arranged on the inner wall of the filtering pipeline and located below the feeding hopper. When the device is used, an external liquid medicine tank slowly injects alum liquid medicine into filtered sewage through a liquid medicine pipe, when sewage above a partition plate drives a buoyancy ball to reach the topmost end of a contact plate, a small motor works, the small motor drives a flow limiting plate to move, the sewage flows out through a liquid leakage pipe in the partition plate, and a large motor drives a reciprocating lead screw to rotate; the reciprocating lead screw drives the scraper to slide back and forth on the outer surface of the sliding rod, the scraper drives the liquid outlet to move back and forth, sewage evenly flows to the separation plate, the scraper scrapes separated solids to the two ends of the separation plate, the solids finally fall into a solid material disc, and the solid-liquid separation device has the advantage of being good in solid-liquid separation effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a solid-liquid separation device for domestic sewage. Background technique [0002] Traditionally, most of the bath water is directly discharged after one-time use. [0003] Under normal circumstances, bathing wastewater accounts for 30% of urban domestic sewage. The bathing water that people use daily is mainly heated tap water. The pollutants contained in bathing wastewater are mainly human skin secretions, hair, dirt, soap and other detergents. For pollutants such as bubbles, the existing bathing wastewater treatment technology simply treats and discharges the wastewater directly, without reusing it, wasting water resources, and the pollutants in the sewage are discharged through the sewage pipe without filtering, resulting in The sewage pipe is clogged. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides ...
