Household water purifying process and system

Abstract

The invention discloses a treatment method and a treatment system for household water purification. The method is to pass tap water into a polypropylene cotton filter core rod, remove suspended solids and large particle impurities in the tap water through the polypropylene cotton filter core rod, and then pass the tap water The tap water filtered through the polypropylene cotton filter rod is pressurized and then fed into the oxidation-resistant composite reverse osmosis membrane, which is filtered through the oxidation-resistant composite reverse osmosis membrane for the second time, and the residual chlorine in the tap water is used to filter the surface of the oxidation-resistant composite reverse osmosis membrane. The microorganisms attached to the water are controlled and killed, and the purified water filtered by the oxidation-resistant composite reverse osmosis membrane is introduced into the pressure tank for storage, and the residual chlorine in the purified water is removed through the activated carbon filter rod when in use, so as to meet the drinking standard of pure water . The invention overcomes the troublesome water source pretreatment and easy pollution of the reverse osmosis membrane in the existing household water dispenser, and provides a domestic water purification treatment method and device with simple water pretreatment and low pollution degree of the reverse osmosis membrane.

Description

Technical field [0001] The invention relates to a treatment method and treatment system for household water purification, and belongs to the technical field of water treatment. Background technique [0002] Because household water purifiers are easy to use and low in running costs for water production, they can be directly installed in the cabinet, saving space and being beautiful, and are becoming more and more popular with consumers. [0003] The current household purified water treatment system is mainly composed of three parts: water pretreatment part, reverse osmosis filtration part and pure water storage. Usually, the tap water in the tap water pipe is filtered through a pp cotton filter element to remove suspended solids in the water. Because the reverse osmosis membrane element has strict requirements on the free chlorine content of the influent, the residual chlorine content is required to be less than 0.1mg / L, otherwise the membrane will be damaged The structure, result...

AI Technical Summary

Problems solved by technology

By applying the oxidation-resistant composite reverse osmosis membrane to domestic water purification treatment, the present invention simplifies the treatment steps of the water treatment system and the treatment device, overcomes the problem that the reverse osmosis membrane is easily polluted in the existing household water dispenser technology, and prolongs the The service life of the reverse osmosis system is extended, the water treatment effect is improved, and the deficiencies of the existing technology can be overcome
