Problems solved by technology

[0002] Due to the large amount of sewage produced in the coal mine production process, the chemical composition of the sewage is complex, and it is usually mixed with solid and liquid. The existing conventional treatment methods are either expensive or incomplete.
Due to the relatively high degree of solid-liquid mixing, when conventional sewage treatment equipment is used for treatment, the filter membrane will be blocked in a short period of time, and it is difficult to separate the solid-liquid of sewage here.

Abstract

The invention relates to a purification device for coal mine water. The purification device comprises a stirring ejector, a sedimentation tank, a solid-liquid separation tank and a filter box. By arranging the stirring ejector in combination with the sedimentation tank of a specific structure, the primary separation efficiency is improved; by improving the material of stirring blades, the service life of a stirrer is substantially prolonged; by arranging an inclined large-aperture filter plate on the solid-liquid separation tank, the solid-liquid separation efficiency is improved; by improving a multi-layer filter plate of the filter box, water obtained finally meets the qualified water quality standard. By the low-cost physical arrangement, coal mine water is efficiently purified.

Description

technical field [0001] The invention belongs to the fields of coal mines and sewage treatment, and in particular relates to a high-durability coal mine water purification device. Background technique [0002] Because coal mine production produces a lot of sewage, the chemical composition of the sewage is complex, and it is usually mixed with solid and liquid. The existing conventional treatment methods are either expensive or incomplete. Due to the relatively high degree of solid-liquid mixing, when conventional sewage treatment equipment is used for treatment, the filter membrane will be blocked in a short period of time, and it is difficult to separate the solid-liquid of sewage here. Therefore urgently need to invent a kind of low-cost coal mine sewage treatment equipment or purification equipment. Contents of the invention [0003] The purpose of the present invention is to propose a high durability coal mine water purification device. [0004] Specifically, it is ac...
