Small sewage treatment device

Abstract

The invention belongs to the technical field of sewage treatment, and particularly discloses a small sewage treatment device. A sewage treatment tank is an annular cavity, a sewage hose is wound in the annular cavity, one end of the sewage hose is connected with a sewage tank, and the other end of the sewage hose is connected with a settling tank. An aeration pipe is sleeved with the sewage hose,and one end of the aeration pipe extends out of the sewage hose to be connected with a small aeration pump. A filter is arranged in the hollow cavity of the sewage treatment tank, the upstream of thefilter is connected with the settling tank through a drain pipe, the downstream of the filter is connected with a water return pipe through a filter pump, and the other end of the water return pipe extends into the sewage treatment tank from the upper end of the sewage treatment tank. The invention aims to enhance the aeration area of sewage and uniformly stir a flocculant added into the sewage, so that the flocculant can be better combined with the sewage to perform sewage treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a small sewage treatment device. Background technique [0002] In some large-scale public places such as exhibitions, mobile public toilets are usually set up, and there is a hand-washing table behind or on the side of the public toilet. Usually, the treatment method of this part of the sewage after washing is directly through the urban sewage discharge pipe network. Discharge is collected and treated uniformly by the sewage plant. Although this treatment method is efficient, with the development of the economy, people's awareness level is also gradually improving, saving water resources, and reusing sewage after treatment is becoming more and more. valued by people. [0003] Therefore, it has gradually become a trend to save water resources from the source and reduce the waste of water resources. At present, some sewage treatment equipment can treat the used sewage and...

Problems solved by technology

[0003] Therefore, it has gradually become a trend to save water resources from the source and reduce the waste of water resources. At present, some sewage treatment equipment can treat the used sewage and directly reuse it, but the overall size of the equipment is large and requires It is not easy to move for long-term use, and the small footprint and easy movement cannot achieve the effect of purification treatment, which is not conducive to the treatment of sewage to achieve the purpose of secondary use
