Copper-silver ion type purification equipment for domestic water

Abstract

The invention discloses copper-silver ion type purification equipment for domestic water. The copper-silver ion type purification equipment for domestic water comprises a pre-filtration device and a copper-silver ion generator sequentially connected to a tap water pipe through a pipeline, wherein the copper-silver ion generator comprises an electrode box and electrode plates arranged in the electrode box, a water inlet and a water outlet are formed in the electrode box, and the electrode plates are made of copper-silver alloy. Ionized copper ions and silver ions can be combined with bacterialcells, and penetrate cell walls to be combined with DNA or RNA in specific parts of the cells to destroy proteases and respiratory enzymes of the bacterial cells, therefore, the dissolution and the death of the bacterial cells are caused to achieve disinfection and sterilization; the copper ions and silver ions are colorless, odorless, strong in chemical stability, and hardly affected by sunlighttemperature and time, so that long-term stable residual concentration can be provided to maintain the disinfection effect, and no toxic by-products are produced; electrodes of the invention adopt thecopper-silver alloy, and the copper and silver ions are dispersed more uniformly to enhance the synergistic effect of the copper and silver ions.

Description

technical field [0001] The invention relates to a water purification device, in particular to a copper-silver ion type domestic water purification device. Background technique [0002] At present, the tap water supply in our country has only undergone preliminary purification treatment, and as domestic water, especially drinking water, it needs to be further purified. In the prior art, reverse osmosis mills are mainly used for further purification, and the purification of reverse osmosis membranes has the following problems: (1) can only filter substances larger than the pore diameter of the reverse osmosis membrane, and substances smaller than the pore diameter cannot be filtered out; (2) reverse osmosis The membrane will filter out many minerals that are beneficial to the human body; (3) the filter element needs to be replaced regularly, and the cost is high; (4) the output ratio is low, only about 1:3; (5) the bacteria content in the treated water Not up to the standard ...
