Sewage treatment device

Abstract

The invention relates to the field of sewage treatment devices and in particular relates to a sewage treatment device. The sewage treatment device comprises a sewage filtering mechanism, an acid and alkali neutralization mechanism and a disinfection mechanism, wherein the sewage filtering mechanism, the acid and alkali neutralization mechanism and the disinfection mechanism are arranged at intervals along a straight line; a material conveying pipeline, which is arranged obliquely, is arranged between the acid and alkali neutralization mechanism and the sewage filtering mechanism; the sewage filtering mechanism comprises a supporting platform, a filtering cylinder and a floating matter treatment assembly; the floating matter treatment assembly comprises a U-shaped supporting plate, a hoisting part, a fishing part and a rotating part. The sewage treatment device provided by the invention has the beneficial effects that relatively large particles in sewage can be removed, acidic substances in the sewage are neutralized and toxic substances in the sewage are removed; the surface of a secondary filtering screen is scrubbed through a scrubbing assembly, and floating matters on the watersurface of the sewage can be fished through the floating matter treatment assembly, without the need of manual operation, so that the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the field of sewage treatment devices, in particular to a sewage treatment device. Background technique [0002] Domestic sewage is mainly the discharge water produced by various kitchen water, washing water and toilet water used in human life. Domestic sewage is mixed with acidic substances. If the acidic substances are not treated, the pipeline will be corroded and the normal operation of the pipeline will be affected. , and the domestic sewage is mixed with toxic and harmful substances, which usually need to be treated. [0003] A new type of domestic sewage treatment device with the patent number CN107963772A, which belongs to the field of sewage treatment devices, including a filter shell, an acid-base neutralization device and an ecological treatment device; the filter shell is set as a cuboid, placed horizontally, and has a collection cavity inside and the filter cavity; the filter plate is obliquely placed in the filte...

AI Technical Summary

Problems solved by technology

[0004] Although the invention is easy to operate, easy to maintain, and has a good sewage treatment effect, it does not mention the treatment of floating objects on the sewage water surface, and manual processing of floating objects is still required, and long-term salvage will bring greater labor intensity to workers When the sewage treatment device treats the sewage for a long time, the particles in the sewage will fall into the filter screen, and the filter holes of the filter screen will be blocked after a long time, and this invention does not have a device that can prevent the filter holes of the filter screen from clogging , affecting the normal operation of the sewage treatment plant
