A sewage filtration treatment device

Abstract

The invention discloses a sewage filtering treatment device. The device comprises a reaction tank, a flange, a water feeding hopper, a bottom support, a base, a material discharge tube, a motor, a telescopic device, a rack, a belt pulley, a drive rod, a spiral unit, a filter net, a controller, a clamping connection block, a protective box and the like. The sewage filtering treatment device has thebeneficial effects that fresh water in the sludge can be extracted effectively through an extrusion manner, so that people can use the water resource thoroughly, in addition, possible aquatic floating organisms in the sewage pumped in the nature world can be removed completely and effectively, so that the aquatic floating organisms do not die in sewage treatment so as not to cause secondary pollution to the wastewater.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to a sewage filtering treatment device, which belongs to the field of sewage treatment equipment. Background technique [0002] Sewage usually refers to some polluted discharge water from domestic and production, mainly domestic sewage, industrial sewage and initial rainwater. The main pollutants of sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants, etc. . Sewage is accompanied by sludge, which also contains a large amount of fresh water, which is discharged along with the discharge of sludge, causing great waste, and the existing devices cannot effectively extract the fresh water in the sludge out, so that people's protection and utilization of water resources have not been carried out to the extreme; at the same time, for some sewage pumped from nature, there may be some light-weight planktonic aquatic organisms in these sewage, if t...

Sewage is accompanied by sludge, which also contains a large amount of fresh water, which is discharged along with the discharge of sludge, causing great waste, and the existing devices cannot effectively extract the fresh water in the sludge out, so that people's protection and utilization of water resources have not been carried out to the extreme; at the same time, for some sewage pumped from nature, there may be some light-weight planktonic aquatic organisms in these sewage, if these planktonic aquatic organisms are not removed The aquatic organisms are effectively removed, and these planktonic aquatic organisms are treated together with the sewage treatment equipment, which may cause the death of these planktonic aquatic organisms during the sewage treatment process, resulting in re-pollution of the sewage
