Sewage filter

Abstract

The invention provides a sewage filter, which synthesizes a shallow tank theory, a dynamic coagulation theory, an accelerated coagulation theory and an inclined plate technology, effectively solves the problem of easiness in blockage of the traditional inclined plate. The sewage filter is used for subdividing raw motion water through by using filter masks and a plurality of through hole structures; and the raw water forms stable eddies at rear edges of plate holes of filter mask bodies. Under the entrainment action of the eddies, non-fluidic substances in the raw water are collected at centers of the eddies and get in continuous contact and collision with one another in eddy cores to undergo a flocculation reaction, and slides down along the mask bodies under the gravity action to settle into a mud collecting hopper, so that the purposes of removing suspended substances in the raw water and cleaning a water body are achieved. The sewage filter can rotate around an axis of a rotating shaft; and a strongly turbulent shear flow is formed through left and right repeated quick rotation to scour an inclined plate at a high speed and to clean deposits and blockages very conveniently.

Description

technical field [0001] The invention relates to a sewage filter capable of accelerating the sedimentation process of sewage treatment, clarifying water bodies and improving the sewage treatment effect. Background technique [0002] The vertical flow sedimentation tank is an important sewage treatment structure, which has many advantages such as small footprint, convenient sludge discharge, contact flocculation and sludge suspension layer interception, and is very suitable for small and medium-sized sewage treatment systems. However, its depth is large, and its adaptability to water impact load and water temperature change is not strong. There are often phenomena such as water distribution and water collection, and the sedimentation effect is unstable; the pool diameter should not be too large. [0003] The advantages of inclined plate and inclined tube sedimentation tanks are large sedimentation area, high hydraulic load, high efficiency, which is more than double that of ot...

Problems solved by technology

[0004] In order to solve the defects that the depth of the vertical flow sedimentation tank is too large, the adaptability to the impact load of water volume and the change of water temperature is not strong, and the traditional inclined plate (pipe) is prone to sludge adhesion and clogging, which affects the sedimentation effect, the sewage filter integrates the shallow Based on pool theory, dynamic coagulation, accelerated flocculation principle and inclined plate technology, the moving raw water is divided and divided by equidistantly arranged filter covers and numerous through-hole structures to ensure uniform distribution of water flow; Or the characteristic of forming a high-speed rotating vortex in the depression makes the raw water generate a stable vortex at the rear edge of the through hole of the filter cover
