Embodiment Construction

[0044] The method for adopting low-temperature plasma to purify household drinking water quality in the present embodiment is to carry out as follows:

[0045] a. Generate hydrogen and oxygen by electrolysis of water;

[0046] b. Using the hydrogen and oxygen described in step a as the discharge gas for the plasma reaction, the drinking water to be treated and the hydrogen and oxygen are used for gas-liquid mixed discharge;

[0047] c. Introduce the treated water after the gas-liquid mixed discharge in step b into the water storage tank for storage until the disinfection by-products DBPs, bacteria and viruses in the water are eliminated and killed.

[0048] In specific implementation, the treated water can be mixed with the drinking water to be treated, the treated water can be diluted, and then jointly introduced into a water storage tank for storage.

[0049] The excess O in the storage tank can also be 3 Backflow to the inlet of drinking water to be treated.

Abstract

The invention discloses a method for purifying quality of household drinking water by adopting lower temperature plasma technology and device thereof, which is characterized in that water is electrolyzed to produce hydrogen and oxygen; the hydrogen and oxygen are taken as electro-discharging gases of reaction of plasma, the drinking water to be processed as well as the hydrogen and oxygen are subject to gas-liquid mixed electro-discharging; the water to be processed after finishing gas-liquid mixed electro-discharging is led into a water storage tank for storing until the sterilization by-products DBPs, bacteria and virus are eliminated and killed. The inventive method can effectively reduce DBPs in water, and has relatively thorough sterilization; fill-in of electrolyzed gases and decomposition of part of ozone during the reaction process both can increase oxygen content in the drinking water, being conducive to safety of drinking water.

Description

technical field [0001] The invention relates to a method and a device for purifying domestic drinking water, more specifically a method and a device for purifying domestic drinking water by using low-temperature plasma technology. Background technique [0002] At present, most of the drinking water purification process in our country adopts the way of chlorination disinfection. According to the national drinking water sanitation standard, the effective chlorine in the water at the end of the pipe network must be greater than 0.05mg / L to ensure the sanitation and safety of drinking water. To achieve this effective chlorine concentration, the chlorine dosage of the waterworks is generally greater than 2mg / L. However, during the pre-chlorination and disinfection of drinking water, chlorine tends to oxidize with certain organic substances in water such as humic acid, and at the same time, electrophilic substitution reactions occur, resulting in a large number of disinfection by...
