Sewage filtration system

Abstract

The invention discloses a sewage filtration system which comprises a primary filter and a secondary filter. The primary filter comprises a primary water tank, a transfer pipe, a sludge discharge assembly and a sludge discharge tank; scrubbing plates are formed on the outer wall of the lower portion of the transfer pipe; scrubbing heads are formed on the scrubbing plates; a secondary water outlet pipe is arranged at the upper end of the secondary filter, and a water inlet pipe and a drainage pipe are arranged at the lower end of the secondary filter; when the system works, a water inlet solenoid valve and a centrifugal pump are switched on, the water after the primary filtration flows into the secondary filter from a primary filtration pipe, a solenoid valve is switched on, the water after secondary filtration is drained from the secondary water outlet pipe, and the water after secondary filtration flows into the primary water tank through a sewage pipe again for primary filtration; due to the fact that power generation equipment is arranged, the sewage filtration system can be used in an area free of power grid coverage, and energy consumption and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the field of water purification equipment, in particular to a sewage filtering system. Background technique [0002] The Chinese Utility Model Patent No. 201320005827.2 proposes a reciprocating rotating tubular ceramic membrane bioreactor. The reciprocating rotating tubular ceramic membrane bioreactor includes a sewage treatment tank, a ceramic membrane module, and a drive ceramic membrane module to reciprocate The rotating power device, a vacuum pump and an aeration device, the ceramic membrane module rotates reciprocatingly with the motor and combined with the gas agitation of the aeration device effectively prevents the membrane surface from sticking to fouling and clogging; Under the condition of gas agitation of the aeration device, only part of the attached silt can be cleaned, and the ceramic membrane module used for filtering is small, and the working efficiency is low; since the ceramic membrane module has been recipro...

[0002] The Chinese Utility Model Patent No. 201320005827.2 proposes a reciprocating rotating tubular ceramic membrane bioreactor. The reciprocating rotating tubular ceramic membrane bioreactor includes a sewage treatment tank, a ceramic membrane module, and a drive ceramic membrane module to reciprocate The rotating power device, a vacuum pump and an aeration device, the ceramic membrane module rotates reciprocatingly with the motor and combined with the gas agitation of the aeration device effectively prevents the membrane surface from sticking to fouling and clogging; Under the condition of gas agitation of the aeration device, only part of the attached silt can be cleaned, and the ceramic membrane module used for filtering is small, and the working efficiency is low; since the ceramic membrane module has been reciprocating and rotating, it drives the outlet pipe to rotate together, so that The connection of the outlet pipe ceramic membrane module is easily damaged
