Filter cloth-filter chamber filtering device and method for disposing sewage

Abstract

The invention relates to a filter cloth-filter chamber filtering device which comprises a filtering device body and a back washing device, wherein the filtering device body comprises filter frames, filter cloth and filter cloth brackets; a plurality of regularly distributed draining through holes are formed in walls of vertically and horizontally communicated branch tubes at the inner parts of filter frames; filtered water outlets are formed in the bottom of the filter frames; the filter cloth brackets are W-shaped corrugate filter screens; the filter cloth is tightly laid on the W-shaped corrugate filter screens, closed filtered water space is formed by the filter frames, the filter cloth and the filter cloth brackets; the back washing device comprises W-shaped corrugate mud suction tubes, cleaning connecting tubes, a cleaning main pipe and a negative pressure suction discharge pipe; mud suction seams are formed in the back washing ends of the W-shaped corrugate mud suction tubes, the mud suction seams are closely matched with the filter cloth laid on the W-shaped corrugate filter screens. A method for disposing sewage, provided by the invention, comprises the steps of filtering, positive pressure air impacting, negative pressure pumping and the like. Through the adoption of the corrugate filter surfaces and the back washing component, the effective filtering area of the filtering device is increased, the work efficiency is high, and the water output is high.

Description

technical field [0001] The invention relates to a filter device and a method for treating sewage, in particular to a filter cloth filter device with a self-cleaning device and a method for treating sewage, belonging to the field of sewage treatment equipment. Background technique [0002] Fiber filter cloth filter is mainly used in surface water purification, advanced sewage treatment, industrial water treatment and other fields. The latter water source can meet the requirements of landscape water, reuse and treatment of reclaimed water, and the requirements of urban sewage treatment plant standard A-level A discharge transformation. The filtration method of the plate filter cloth filter tank is divided into the form of filtration from the inside to the outside and the form of filtration from the outside to the inside. The typical solution of the filter from the inside to the outside is the similar product of FLUIDYNE Company. At the same time, multiple solenoid valves are ...
