Drinking water purifying device combining photocatalysis and inorganic membrane filtration technology

Abstract

The invention relates to a drinking water purifying device combining photocatalysis and inorganic membrane filtration technology, comprising an active carbon filtration assembly, an inorganic membrane filtration assembly and a photocatalysis membrane assembly. Water flows into the active carbon filtration assembly and then passes through the inorganic membrane filtration assembly, and finally, purified drinking water flows out of the photocatalysis membrane assembly. The inorganic membrane filtration assembly and the photocatalysis membrane assembly are both mounted vertically to prevent sediment from polluting membranes and avoiding dead flow areas; the active carbon can be soaked in edible alcohol for being utilized repeatedly; the inorganic membrane of the inorganic membrane filtration assembly has high mechanical strength and can resist corrosion; and all assemblies of the device have long service lives and have no needs of frequent cleaning and replacement. The invention adopts the photocatalysis membrane action for sterilization, has good effect, can purify water in depth, loads phtocatalyst on stainless steel or the inner wall of a glass tube and adopts an ultraviolet source to inspire the photocatalysis membrane to react so as to achieve the purpose of sterilization and trace organic matter degradation, have no problems of catalyst separation, and can not cause second water pollution.

Description

technical field [0001] The invention relates to water source purification, uses photocatalysis technology and inorganic membrane filtration technology to purify drinking water, and is specifically a drinking water purification device integrating photocatalysis and inorganic membrane filtration technology. Background technique [0002] In terms of drinking water treatment, most of the existing equipment currently uses adsorption methods to remove trace organic matter in water, and there are limitations in adsorption balance and saturation, resulting in incomplete removal of organic matter. Cotton or organic membrane filter elements are mostly used for suspended solids filtration. Although good power effects can be obtained, the mechanical strength and corrosion resistance are limited, and they cannot achieve the purpose of sterilization. Sterilization measures mostly use ultraviolet light to sterilize. In the absence of a catalyst, the sterilization effect of this method is n...
