Multi-stage treatment and purification device for underground water pollution

Abstract

The invention relates to the technical field of water pollution treatment, and discloses a multi-stage treatment and purification device for underground water pollution. The multi-stage treatment andpurification device for underground water pollution comprises a water collection chamber, a first water pump, a stirring chamber, an aeration oxidation tank, a filter screen, a second water pump, a heavy metal reaction tank, an activated carbon filter and a water quality detector. The top of the stirring chamber is fixedly connected with a rotating motor, and the output end of the rotating motor is fixedly connected with a first gear; two symmetrically distributed first rolling bearings are embedded in the top of the stirring chamber; a stirring shaft is fixedly connected to the inside of eachfirst rolling bearing, and a second gear is fixedly connected to the outer wall of the top of each of the two stirring shafts; the two second gears are engaged with the first gear; a plurality of stirring blades which are distributed in a staggered manner are fixedly connected to the outer wall of each of the two stirring shafts; and fixing blocks are fixedly connected to the left side and the right side of the filter screen separately. According to the multi-stage treatment and purification device for underground water pollution, the mixing efficiency of sewage in the stirring chamber can beeffectively improved, and the filter screen can be conveniently disassembled and assembled.

Description

technical field [0001] The invention relates to the technical field of water pollution treatment, in particular to a multi-stage treatment and purification device for groundwater pollution. Background technique [0002] At present, with the rapid development of the city, the amount of garbage collected is increasing, and there are more and more garbage dumps. This will inevitably lead to the occurrence of garbage seepage that pollutes groundwater. These problems continue to aggravate, making the original There is not much groundwater, and the amount that can be directly used by people becomes even less. [0003] After searching, the Chinese patent authorization number is CN205773892U, which discloses a multi-stage treatment and purification device for groundwater pollution, including a water collection chamber, a first water pump, a mixing chamber, a motor, a stirring shaft, a stirring paddle, an aeration oxidation tank, a filter Net, second water pump, heavy metal reaction...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that in the prior art, when the sewage is stirred evenly by using a stirring chamber, only a single stirring shaft is used to stir it, and the stirring rate is too slow, thereby affecting the mixing efficiency of the sewage, and when using the filter When the filter screen is used to filter the impurities in the sewage, the filter screen is easy to block, and because the filter screen is fixedly connected with the aeration oxidation tank, it is not easy to disassemble it, thus affecting the flow of sewage.
