Solid-liquid separation device based on sewage treatment

Abstract

The invention discloses a solid-liquid separation device based on sewage treatment. The device comprises a device body, wherein a solid-liquid separation cavity is formed in the device body, a water inlet pipe is fixed on the upper side of the solid-liquid separation cavity, the lower end of the water inlet pipe is communicated with the solid-liquid separation cavity, and the upper end of the water inlet pipe is connected with an external drainage pipe; a filter screen is fixed in the solid-liquid separation cavity, and a water treatment device is arranged on the lower side of the solid-liquidseparation cavity. The separation cavity in the solid-liquid separation device is obliquely arranged, solid waste is mutually squeezed and dewatered through a push plate when being conveyed, so thatsolids and liquid can be completely separated initially. Separated water can be deodorized and drained, environmental water pollution is reduced, the separated solids are centrifugally dewatered, so that the lowest water content of the solids is reached, and subsequent waste classification and recovery treatment is facilitated. The device has high solid-liquid separation efficiency, and is convenient to install and use.

Description

technical field [0001] The invention relates to the technical field of environmental water treatment, in particular to a solid-liquid separation device based on sewage treatment. Background technique [0002] The solid-liquid separation in the existing sewage treatment is basically completed through the filter screen, and the separated water is directly discharged into the external water system without deodorization treatment, which increases water pollution, and the separated solid waste has a high moisture content, and the subsequent Recycling and transportation all bring inconvenience, and the solid-liquid separation efficiency of the device is low, and energy consumption is large. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] technical problem: [0004] The existing solid-liquid separation device has a simple separation structure, low separation efficiency, and high moisture content of t...
