Wastewater-free water purifier

Abstract

The invention discloses a wastewater-free water purifier which can fully utilize wastewater (tail water) and truly achieve wastewater zero discharge. The wastewater-free water purifier comprises a source water inlet, a first manual mechanical valve, a first electrically-controlled one-way valve, a first pressurizing pump, a first-stage filter, a first water quality sensor, a second-stage filter, a second water quality sensor, a reverse osmosis membrane filter, a third water quality sensor, a purified water storage device, a first water level sensor, a purified water storage tank, a yielding water controller, a second electrically-controlled valve, a flowmeter, a purified water outlet, a third electrically-controlled valve, a second pressurizing pump, a second water level sensor, an ultraviolet disinfection lamp tube, a fourth water quality sensor, a wastewater treatment tank, a third pressurizing water pump, a fourth electrically-controlled one-way valve, a third water level sensor, a first pressure sensor, a high-pressure wastewater storage tank and the like. The high-pressure wastewater storage tank is additionally arranged and communicated with a water pipeline in a housing estate, and therefore the wastewater (tail water) generated in the purified water preparation process can be all effectively utilized.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to an energy-saving and environment-friendly waste water purifier. Background technique [0002] Statistics show that water pollution incidents occur frequently in my country, and the unsafe water quality of drinking water sources affects about 140 million people. The shocking water pollution situation has made ordinary residents' demand for safe drinking water increasingly strong, and it is very necessary to install water purifiers at home. [0003] The current water purifiers usually filter the source water by means of hierarchical filtration. "RO membrane" (reverse osmosis membrane) is generally used as the filter membrane. The reverse osmosis membrane uses reverse osmosis technology to remove bacteria, viruses, and microorganisms in water , precious metals, etc. to eliminate. Ultimately, clean and purified water is provided to the user. However, due to the inherent ch...
