Household reverse osmosis water purifier

Abstract

The invention discloses a household reverse osmosis water purifier. A raw water tank is connected with the water inlet end of a primary filter; the water outlet end of the primary filter is connected with the water inlet end of a secondary filter; the water outlet end of the secondary filter is connected with the water inlet end of a first reverse osmosis film filter; the water outlet end of the first reverse osmosis film filter is respectively connected with a purified water output pipeline and a wastewater output pipeline; the outlet end of the purified water output pipeline is connected with the water inlet end of a post-filter; the water outlet end of the post-filter is connected with a purified water output faucet; the outlet end of the wastewater output pipeline is connected with the water inlet end of a second reverse osmosis film filter; the water outlet end of the second reverse osmosis film filter is respectively connected with a wastewater return pipeline and a wastewater output faucet; and the wastewater return pipeline is connected to the raw water tank. According to the mode, the household reverse osmosis water purifier disclosed by the invention has the advantages that odor and abnormal color of raw water can be effectively removed, high-efficiency sterilization is realized, secondary pollution of the purified water is avoided, the drinking water is sanitary, the filtered wastewater can serve as washing water and can be subjected to cyclic purification, and the purification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of household water purifiers, in particular to a household reverse osmosis water purifier. Background technique [0002] The water purifier is also called a water purifier or a water filter. Its technical core is the filter membrane in the filter element device. [0003] The reverse osmosis water purifier is a very good quality-based water supply system. After the tap water is filtered by PP melt-blown filter element, granular activated carbon adsorption filter, and compressed activated carbon filter, the tap water is pretreated to remove residual chlorine, suspended solids, rust, Colloids, etc., and most organic matter. Afterwards, part of the water is filtered through the reverse osmosis membrane and post-installed granular activated carbon to obtain pure water for drinking. [0004] At present, many reverse osmosis water purifiers fail to undergo the second-stage treatment after the first three treatmen...

AI Technical Summary

Problems solved by technology

[0004] At present, many reverse osmosis water purifiers fail to pass the second-stage treatment after the first three treatments, and become concentrated water flowing out, causing a lot of waste of precious water resources.
