Convenient-to-clean sedimentation treatment device for municipal sewage

Abstract

The invention discloses a convenient-to-clean sedimentation treatment device for municipal sewage, and relates to the technical field of municipal sewage treatment.The convenient-to-clean sedimentation treatment device comprises a water inlet hopper, a flow guide assembly and a centrifugal sedimentation assembly, a water filtering tank is fixed to the lower portion of the water inlet hopper, a filtering assembly is installed in the water filtering tank, and drainage pipes are fixed to the two sides of the lower portion of the water filtering tank; a water drainage pipe is arranged below the water inlet pipe, a flocculation mixing chamber is installed below the water drainage pipe, a first flocculant layer is arranged on the inner wall of the flocculation mixing chamber, a stirring assembly is installed in the flocculation mixing chamber, the flow guide assembly is fixed below the flocculation mixing chamber, and the flow guide assembly comprises a discharging hopper, a flow guide plate, an outer frame, a second flocculant layer and a water drainage flow channel. According to the sedimentation treatment device convenient to clean and used for municipal sewage, sewage can make full contact with a flocculating agent layer, so that the gravity sedimentation efficiency is improved, centrifugal sedimentation, flocculating sedimentation and gravity sedimentation can be combined, municipal sewage is fully settled, and therefore the good sedimentation treatment effect is achieved.

Description

technical field [0001] The invention relates to the technical field of municipal sewage treatment, in particular to an easy-to-clean sedimentation treatment device for municipal sewage. Background technique [0002] The main source of municipal sewage is domestic sewage. The waste water produced by people in their daily life activities is mainly domestic waste and human excrement, including waste water from kitchen washing, showering, laundry, etc., and sewage from flushing toilets. In the process of sewage treatment, sewage sedimentation can be used. Sedimentation is one of the most basic methods in water treatment. It is a process that uses the precipitable properties of suspended particles in water to produce sinking under the action of gravity to achieve solid-liquid separation. It is often used in the pretreatment process of wastewater and the initial precipitation before biological treatment structures. Settlement of sewage includes gravity settling, free settling, ce...

AI Technical Summary

Problems solved by technology

[0003] The existing sedimentation treatment devices for municipal sewage generally adopt simple gravity sedimentation, which cannot combine centrifugal sedimentation, flocculation sedimentation and gravity sedimentation, and the effect of sedimentation treatment is not good. Therefore, we propose an easy-to-clean municipal sewage Settlement treatment device
