Self-cleaning sewage treatment unit

Abstract

The invention discloses a self-cleaning sewage treatment unit. The unit comprises a container for forming sedimentation separation, wherein the container is of a barrel-shaped structure; a water inletand a sewage outlet are formed in the low part of the container, and a water outlet is formed in the upper part of the container; the inside of the container is divided into a plurality of sedimentation separation areas by a plurality of partitions distributed vertically, and the adjacent sedimentation separation areas are communicated through water distribution holes formed in the partitions; arotary cleaning device driven by a power source is arranged in the container and used for rotationally cleaning sediment by a plurality of cleaning members which are located in the sedimentation separation areas respectively. Preferably, the container is of a barrel-shaped structure; the water distribution holes in the adjacent partitions of the plurality of partitions are distributed in the radial direction of the partitions in a manner that edges and middles are staggered. The unit has the beneficial effects that the sedimentation decontamination effect is improved through slow flow range extending; the cleaning members driven by the same power source are arranged in each sedimentation area, mechanical power cleaning can be conveniently realized, and accordingly, traditional manual cleaning is replaced, labor intensity is effectively reduced, and the cleaning convenience is improved.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a self-cleaning sewage treatment unit for oil-free waste water. Background technique [0002] In the treatment of industrial wastewater, due to the different types of processed products and process methods, the components in the wastewater are also different. For example, the wastewater produced in heavy industry and light industry production has great difference. Lubricating oil, cooling oil or similar cooling fluids are unavoidably used in most heavy industrial processing industries, while oil pollution should be avoided in the production process of light industrial products, such as clothing trade and footwear. Therefore, there are no oil pollutants in the wastewater, and the corresponding wastewater treatment process is relatively simple. Most of them only need to adopt the traditional gravity separation method, that is, to use the principle of gravity to separate the suspen...

Problems solved by technology

However, it is difficult to clean up the sediment in this type of treatment device, and the degree of mechanization is low, and a large amount of manual work is usually used to complete it.

High labor intensity and low efficiency
