Abstract

The invention relates to an ultraviolet light-PVDF hybrid membrane catalytic oxidation water purifying device. The device solves the problem that organic micro-pollution is difficult to eliminate in conventional water supply treatment processes. The ultraviolet light-PVDF hybrid membrane catalytic oxidation water purifying device consists of a reactor, flat-plate membrane modules, ultraviolet lamp banks and a water collecting pipe, wherein the curtain type membrane component consists of an upper membrane shell, a PVDF hybrid membrane and a lower membrane shell; and the ultraviolet lamp bank consists of a first ultraviolet lamp and a second ultraviolet lamp. The ultraviolet light-PVDF hybrid membrane catalytic oxidation water purifying device is used for water purifying treatment of direct drinking water in residential areas and for water purifying treatment in various types of water plants.

Description

technical field [0001] The invention relates to an ultraviolet light-PVDF hybrid membrane catalytic oxidation water purification device. Background technique [0002] Water is one of the basic substances for the survival and development of human society, and a key factor for the sustainable development of national economy and society. The quality of drinking water directly affects the health of the people and the stability of the society. Party and state leaders have repeatedly emphasized "let the common people drink safe water". With the intensification of water source pollution and the continuous improvement of residents' requirements for drinking water quality, especially the increase of national drinking water standards from 35 to 106, the demand for water treatment technology, especially advanced water treatment, is becoming more and more urgent. [0003] Drinking water safety is a top priority in China. In areas with poor water quality it can cause health and social ...
