Cloth media filter system and sewage treatment method thereof

Abstract

The invention relates to a cloth media filter system which comprises a filter device, a filtrating device and a backwashing device. The filter device comprises a sewage treatment area, a filtered water area and a water drainage area. The filtrating device comprises a plurality of filtrating units regularly arrayed, and each filtering unit comprises a filtering frame, filtering cloth and a filtering cloth support, wherein the filtering frame is a hollow latticed frame, the filtering cloth support is a W-shaped corrugated filtering screen, and the filtering cloth 220 is compactly laid on the filtering screen. The backwashing device comprises a driving power device and a backwashing negative pressure pipeline, the driving power device comprises a driving platform, a driving guide rail and a driving motor, and the backwashing negative pressure pipeline comprises a dredge pump, a sludge conveying pipe, a cleaning header pipe, a cleaning connecting pipe and a W-shaped corrugated sludge suction pipe. A sewage treatment method of the cloth media filter system comprises the steps of filtering, air washing, backwashing water washing and the like. According to the cloth media filter system and the sewage treatment method of the cloth media filter system, the effective filtration area of the filtering device is increased through a corrugated filtering surface and the backwashing component, the working efficiency is high, the water yield is large and water output quality is good.

Description

technical field [0001] The invention relates to a filter system and a method for treating sewage, in particular to a filter cloth filter system with a self-cleaning device and a method for treating sewage, belonging to the field of sewage treatment systems. Background technique [0002] Fiber filter cloth filter is mainly used in surface water purification, advanced sewage treatment, industrial water treatment and other fields. It mainly removes suspended solids in sewage through filter media, and can remove part of phosphorus in sewage at the same time when combined with purification chemicals. After filtration The final water source can meet the requirements of landscape water, reclaimed water reuse and treatment, and the requirements of Class A discharge renovation of urban sewage treatment plants. The filter method of the plate filter cloth filter tank is divided into the form of filtering from the inside to the outside and the form of filtering from the outside to the i...
