Abstract

The invention provides a water purifier with a catalytic oxidation function, and relates to a water purifier. The problem is solved that organic microbial pollution and membrane pollution are difficult to remove during a present water treatment process. A ceramic filter core is connected with an active carbon filter core through a pipe. A polyvinylidene fluoride hybrid membrane member comprises a membrane member shell and a plurality of membrane filaments. The membrane member shell is an enclosed cylinder, the plurality of membrane filaments are arranged in the inner cavity of the membrane member shell vertically. A plurality of water inlets are arranged in the lower part of the membrane member shell. An ultraviolet lamp is embedded among the plurality of membrane filaments vertically. The membrane filaments are organic-inorganic composite ultrafilter membranes prepared through addition of nano-additives into polyvinylidene fluoride resin. An end socket with a valve is connected with the upper end of the polyvinylidene fluoride hybrid membrane member A water outlet of an active carbon filter core is connected with a water inlet of the polyvinylidene fluoride hybrid membrane member through a pipe. The water purifier can be used for water purification processing of household water purifiers and district direct drinking water.

Description

technical field [0001] The invention relates to a water purifier, in particular to a water purifier with catalytic oxidation function. 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 pr...
