Multi-stage sewage filtration treatment device

Abstract

The invention discloses a sewage multi-stage filter processor, comprising a sewage treatment box, a dirt collection box, a first-stage filter screen plate, a second-stage filter screen plate, and a third-stage filter screen plate. The middle part of the upper end of the sewage treatment box is connected Water pipes, the middle part of the lower end of the sewage treatment tank is connected to the water outlet pipe, the sewage treatment tank is equipped with a mesh block, and there are slots on both sides of the mesh block, the number of mesh blocks is at least three and along the sewage The central axis of the processing box is distributed at equal intervals from top to bottom, and the first-stage filter screen, the second-stage filter screen and the third-stage filter screen are sequentially inserted into the slots of the screen plate clamping blocks distributed from top to bottom. A sewage multi-stage filter processor is described, which is convenient for the installation and disassembly of the first-stage filter screen board, the second-stage filter screen board or the third-stage filter screen board, realizes multi-stage filtration of sewage, has a good sewage discharge effect, and saves time and effort.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage multi-stage filter processor. Background technique [0002] With the continuous development of the economy, the discharge of domestic sewage and industrial sewage is increasing day by day. After the sewage that does not meet the discharge standards is discharged into the water body, it will lead to the pollution of surface water and groundwater, and the pollution of surface water and groundwater will lead to the pollution of the available water. The amount of water resources used is decreasing day by day. Once the water body is polluted, it is quite difficult to restore it to its original state in a short period of time. This will inevitably affect the production of industry, agriculture and fishery, and directly or indirectly affect people's life and health. come to harm.

[0003] The equipment for sewage treatment needs to filter the sewage before sewage purification to filter out the impurities in the sewage. The existing filters only have one layer of filter mesh. Because the dirt is of different sizes, the filter with one pore size The mesh cannot meet the filtration requirements of sewage, and the pore size is too small to easily cause dirt clogging, and the pore size is too large to achieve the filtering effect

Moreover, the filter screen of the existing filter is usually fixed installation, which is inconvenient to disassemble and replace the screen plate. The filter needs to be disassembled to replace it. effect, it is difficult to meet the needs of use
