Abstract

A continuous microfilter system for cleaning reclaimed water features that the minipore filter membrane tubes are serially or parallelly combined to form membrane assembly and the staggered current filter and pulsive air-water reverse flush are used. Its advantages are high strength and high water penetrability.

Description

technical field [0001] The present invention relates to a filter system of reclaimed water membrane method; in particular, it relates to a large-scale cross-flow filter and pulsed air-water recoil of composite microfiltration membrane tube, so that domestic sewage or industrial wastewater can effectively remove impurities, bacteria, In addition to colloid, to meet the national standards for miscellaneous water. Background technique [0002] The United Nations report predicts that by the 21st century, fresh water will become the most tense natural resource in the world. my country is a country that lacks water resources, coupled with the water pollution and water supply shortage brought about by the rapid economic development, the water crisis has become a severe and urgent problem that needs to be solved urgently. [0003] Domestic sewage and industrial wastewater can only meet the discharge standard after being treated by conventional chemical or physical methods, and the ...
