Document Type and Number:
WIPO Patent Application WO/2024/078021
Kind Code:
A1
Abstract:
A water-saving water purification system with controllable water quality, and a control method therefor. The system comprises a raw water regulation and control device (1), a concentrated water regulation valve (3), a mixed water measurement device (2), a membrane filter (5), a purified water measurement device (7) and a water-dispensing device (20), wherein the flow rate of raw water entering the mixed water measurement device (2) is regulated by the raw water regulation and control device (1); the flow rate of concentrated water entering the mixed water measurement device (2) is regulated by the concentrated water regulation valve (3); the concentrated water and the raw water are mixed in the mixed water measurement device (2), and then the mixed water is output to the membrane filter (5); and the mixed water is treated by the membrane filter (5) to produce water. During this process, the purified water measurement device (7) and the mixed water measurement device (2) perform spectrum test and ion concentration measurement on the water upstream and downstream of the membrane filter (5) and perform feedback to accurately regulate and control the raw water regulation and control device (1) and the concentrated water regulation valve (3), such that adjusted purified water meets the standard requirements.
