Whole house dual water supply system and device

Abstract

The invention relates to a whole house dual water supply system and device. The system comprises a pre-filtering treatment unit, an ultrafiltration membrane treatment unit, a concentrated water, a purified water and a water distributing treatment unit, wherein the pre-filtering treatment unit is connected with tap water; the ultrafiltration membrane treatment unit is connected with the pre-filtering treatment unit and respectively connected with the concentrated water and the purified water; and the purified water is connected with the water distributing treatment unit through a backflushing treatment unit. The pre-filtering treatment unit comprises a plurality of parallel PP fiber cotton pre-filtering modules; and the PP fiber cotton pre-filtering modules are respectively connected with the tap water; the ultrafiltration membrane treatment unit comprises a plurality of hollow fiber ultrafiltration membrane modules; each stage of hollow fiber ultrafiltration membrane module comprises a plurality of parallel hollow fiber ultrafiltration membranes; and each PP fiber cotton pre-filtering module is connected with one stage of hollow fiber ultrafiltration membrane module. The water distributing treatment unit comprises a softened water treatment unit and a drinking water treatment unit; and technical problems that the water quality of the domestic water cannot be guaranteed and the domestic water cannot be distributed in a dual way according to the purposes in the prior art are solved.

Description

technical field [0001] The invention relates to a water supply system, in particular to a quality-differentiated water supply system for the whole house. Background technique [0002] For a long time, people have used urban tap water as domestic water, including drinking, cooking, bathing, washing, sanitation, boiler equipment and other water needs. At present, most water plants in my country still use the traditional process of "coagulation-sedimentation-filtration-chlorination disinfection", which is not only powerless to deal with water bodies that have been polluted by a large amount of industrial wastewater and domestic sewage, but even counterproductive; The aging of the water tank, secondary pollution caused by inadequate maintenance of the water tank, etc., lead to rust, a small amount of sand, microorganisms, bacteria, etc. in the water quality of household tap water, endangering people's health and equipment life. [0003] With the improvement of material civilizat...
