Filter-cloth filter for water treatment

Abstract

The invention relates to a filter-cloth filter for water treatment. A filter body consists of a raw water area, a filtered clean water area, an output water area, a mud storage tank, a water inlet pipe, a water outlet pipe, a mud discharge pipe and the like; a filter element of filter main body equipment consists of filter cloth, a center pipe, a filter cloth bracket, a filter element flange, a flange washer, a flange hoop and the like; back-flushing equipment mainly consists of a suction water pump, a suction disc, a mud suction trunk pipe, a mud suction branch pipe, a vehicle frame and the like. The raw water area is positioned above the filtered clean water area, and the raw water area and the filtered clean water area are separated by a PVC (polyvinyl chloride) plate and a stainless steel plate; the upper end of the filter element is communicated with the raw water area through a water inlet of the center pipe, and the top end of the filter element flange is level with the top end of the PVC plate; the center pipe has double effects of pumping the bottom sediment of the filter element while performing flow guide and back-flushing; protection edges are arranged around a suction port of the suction disc, and elastic sealing rings are mounted. Compared with other filter-cloth filters, the filter-cloth filter provided by the invention has three major advantages of no underwater power equipment, no contact with the filter cloth in back-flushing and few valves.

Description

technical field [0001] The invention relates to the technical field of water treatment devices, in particular to a novel filter cloth filter tank applied to advanced sewage treatment and reuse of reclaimed water, which has a good removal effect on fine suspended matter. Background technique [0002] With the increasing shortage of water resources, reuse of reclaimed water has become an effective way to solve the shortage of water resources and provide a new water source for urban water use. As a key treatment unit in the reclaimed water treatment process, the reasonable selection of filtration facilities is related to the treatment efficiency and economic efficiency of the entire reclaimed water treatment. Cloth filter technology is a new type of surface filtration technology developed in recent years, which can replace traditional deep bed filtration equipment. Emerging in the advanced treatment of sewage. At present, there are two main types of filter cloth filters on th...
