Problems solved by technology

[0003] In the Chinese utility model patent document with the publication number CN208980522U, a dynamic subsidence sewage treatment device is disclosed. The drive motor in the dynamic subsidence sewage treatment device drives the drum to rotate through the friction force between the drive roller and the outer wall of the drum to realize The slow rotation of the drum, when the sewage enters the drum, it will rotate accordingly. During the rotation, the sludge will be quickly lowered, and the water will float up. The water will flow into the MBR biofilm filter plate to filter step by step. The mud settling speed is slow, and the separation speed is slow, and the treatment efficiency is low

Abstract

The invention discloses a dynamic sedimentation type sewage treatment device, belonging to the field of sewage treatment. The dynamic sedimentation type sewage treatment device comprises a separationbox, wherein a feeding hole is fixedly formed in one end of the top of the separation box; supporting legs are fixedly connected to two ends of the bottom surface of the separation box; fixed seats are fixedly connected to two ends of the top of the separation box; the top of the fixed seat is fixedly connected with a settling box; the bottom end of the settling box is fixedly connected with a plurality of bottom covers; a bottom pipe is fixedly arranged between and connected with the bottom cover and the separation box; a flow guiding and conveying device is fixedly arranged at one end of thesettling box; a solid-liquid separation device is arranged in the separation box; and a centrifugal sedimentation mechanism is arranged in the settling box. By arranging the centrifugal sedimentationmechanism, sludge in sewage can be subjected to rapid centrifugal sedimentation, the sludge can be separated from water by arranging the solid-liquid separation device, and separated water can be conveyed and discharged by arranging the flow guiding and conveying device, so rapid and perfect sewage filtering treatment is realized.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a dynamic settling sewage treatment device. Background technique [0002] Existing sewage treatment equipment all adopts conventional settling tanks, filter screens, filter membranes and other equipment to carry out. Ground infrastructure is required, which occupies a large area and cannot be moved. So there are some all-in-one devices. Most of the current sewage deposition adopts natural sedimentation, which takes a long time to settle. It needs to wait for a long time for sedimentation after sewage discharge. During this period, it is not allowed to discharge sewage again to affect the deposition effect, and the cycle efficiency is low. In the membrane filtration technology, most of the existing working methods adopt natural infiltration or pressurized filtration. The sewage fluidity of natural infiltration is poor, and the sludge accumulation will seriously affect the filtrat...
