Multi-stage sewage filtration treatment device

Abstract

The invention discloses a multi-stage sewage filtration treatment device. The multi-stage sewage filtration treatment device comprises a sewage treatment box, a dirt collecting box, a primary filtering screen, a secondary filtering screen and a ternary filtering screen, wherein the middle of the upper end of the sewage treatment box is connected with a water inlet tube; the middle of the lower end of the sewage treatment box is connected with a water outlet tube; at least three screen clamping blocks are mounted in the sewage treatment box; slots are formed in two sides of each screen clamping block; the screen clamping blocks are equidistantly distributed along the axis of the middle of the sewage treatment box from top to bottom; and the primary filtering screen, the secondary filtering screen and the ternary filtering screen are successively inserted in the slots of the screen clamping blocks which are distributed from top to bottom. By the multi-stage sewage filtration treatment device, assembling and disassembling of the primary filtering screen, the secondary filtering screen or the ternary filtering screen are facilitated, multi-stage filtration of the sewage is realized, the sewage discharging effect is good, and troubles and labor are saved.

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
