Filter cloth for water treatment

Abstract

The invention discloses filter cloth for water treatment. The filter cloth at least comprises a dust-removing filter cloth layer, wherein the dust-removing filter cloth is prepared by weaving warp yarns and weft yarns in a dual structure; the warp yarns adopt polyester monofilaments; the weft yarns are of a dual embedding structure; the weft yarns comprise a core material; the core material adoptsat least one of polyester monofilaments or basalt fibers or composite fibers; a reinforced layer is coated outside the core material; the reinforced layer is of a closed barrel structure formed by repeatedly winding the polyester monofilaments by taking the core material as the center or weaving materials with filtering effects; and antistatic coatings and / or adsorption coatings are arranged on the upper and lower sides of the dust-removing filter cloth. Since the surface of the monofilaments is smooth, some small particles penetrate. Therefore, the weft yarns adopt the dual embedding structure, and the smoothness of the weft yarns is reduced. Meanwhile, the compactness is improved, the filtering effect is improved, and the filter cloth is high in pressure resistance, simple in process and easy to operate.

Description

technical field [0001] The invention relates to the technical field of textile chemical industry, in particular to a filter cloth for water treatment. Background technique [0002] Today's environmental protection has attracted more and more attention, and in recent years, environmental degradation is an important problem that plagues us. Urban pollution sources are caused by urban population concentration, urban domestic sewage, garbage and waste gas causing water pollution. The pollution of water bodies by urban pollution sources is mainly domestic sewage, which is a mixture of various sewage produced in people's daily life, including sewage discharged from kitchens, laundry rooms, bathrooms and toilets. The industrial and domestic wastewater discharged from urban areas in the world alone is as high as 500 cubic kilometers a year, and every drop of sewage will pollute several times or even dozens of times the water body. Therefore, the purification of water body is also ...

Problems solved by technology

Therefore, the purification of water body is also particularly important. In sewage purification treatment, filtration is the most critical link. At present, most of them use filter cloth or filter element for filtration. The filter cloth has poor filtering effect and can only remove large particles of impurities, small particles substance difficult to remove
