Problems solved by technology

[0002] Some water purification equipment in the related art is not equipped with a waste water recovery system, resulting in waste of water resources
And some water purification equipment with wastewater recovery system, some of them recycle all the wastewater, resulting in too high TDS value of water quality (total dissolved solids concentration), which damages the life of the membrane and unstable water quality; some of them recycle part of the wastewater, but the water purification The water quality of the system is also unstable, and the life of the membrane is greatly shortened.

Abstract

The invention discloses a water purification device. The water purification device comprises a raw water inlet, a pure water outlet, a concentrated water outlet, a front-mounted filter element, a membrane filtration filter element with a concentrated water port and a pure water port, a concentrated water pipe which is connected with a waste water regulating valve in series, a pure water pipe, a booster pump and a waste water recovery pipe. The front-mounted filter element is connected with the raw water inlet; an inlet of the membrane filtration filter element is connected with an outlet of the front-mounted filter element; the booster pump is connected between the front-mounted filter element and the membrane filtration filter element in series; the concentrated water pipe is respectively connected with the concentrated water port and the concentrated water outlet; the pure water pipe is respectively connected with the pure water port and the pure water outlet; and one end of the waste water recovery pipe is connected between the waste water regulating valve and the concentrated water port, and the other end is connected between the booster pump and the front-mounted filter element. According to the water purification device disclosed by the invention, part of concentrated water in the water purification system flows back, water quality of the water purification system can achieve a stable state, and the problem of waste of water resources of the water purification device is solved.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to a water purification equipment. Background technique [0002] Some water purification equipment in the related art is not equipped with a waste water recovery system, resulting in waste of water resources. And some water purification equipment with wastewater recovery system, some of them recycle all the wastewater, resulting in too high TDS value of water quality (total dissolved solids concentration), which damages the life of the membrane and unstable water quality; some of them recycle part of the wastewater, but the water purification The water quality of the system is also unstable, and the life of the membrane is greatly shortened. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the present invention proposes a water purification device that recove...
