Domestic sewage treatment machine

Abstract

The invention relates to a domestic sewage treatment machine, comprising a machine case, wherein the machine case is equipped with a machine cover; an underwater air pump is arranged in the cavity of the machine case; one end of the underwater air pump is equipped with an air suction pipe, and the air suction pipe is arranged outside a water surface; the other end of the underwater air pump is equipped with an exhaust tube, and the exhaust tube is arranged inside the cavity of the machine case; a water pump is also arranged in the cavity of the machine case, and one end of the water pump is equipped with a drainage pipe; a net bucket is arranged inside the machine case; the water pump and the underwater air pump are arranged in the net bucket is arranged in the machine case, the water pump and the underwater air pump are arranged in the net bucket, and a large amount of filtering materials are filled between the machine case and the net bucket. Compared with the prior art, the domestic sewage treatment machine has beneficial effects of simple structure and delicate machine body.

Description

technical field [0001] The invention belongs to the field of sewage treatment devices, and in particular relates to a domestic sewage treatment machine. Background technique [0002] At present, there are two main methods of sewage filtration: physical filtration and biological filtration. Generally speaking, physical filtration is to pass through small gaps. The filter material is activated carbon, sand, ceramics and other things with small gaps (porosity). However, the small gaps are easy to clog to a certain extent, and large amounts of sewage cannot be treated. [0003] At the same time, if the water cannot decompose the dirt through biological filtration (bacteria tank), the water cannot be restored to its original state. For this reason, we have to manufacture large-scale biological treatment tanks in the past. Contents of the invention [0004] In order to overcome the deficiencies in the physical filtration process in the prior art and to avoid additional manufact...

Generally speaking, physical filtration is to pass through small gaps. The filter material is activated carbon, sand, ceramics and other things with small gaps (porosity). However, the small gaps are easy to clog to a certain extent, and it cannot treat a large amount of sewage.

[0003] At the same time, if the water cannot decompose the dirt through biological filtration (bacteria box), the water cannot be restored to its original state. For this reason, in the past, we had to manufacture large-scale biological treatment tanks
