Abstract

The invention discloses a micro wastewater purifier; a pressure barrel is connected to an internal purified water passage and a purified water reflow passage; the purified water reflow passage is connected to the water incoming end of an RO (reverse osmosis) filter element, and a reflow electromagnetic valve is mounted on the purified water reflow passage; the concentrate end of the RO filter element is connected to an internal concentrate passage that is divided into two branches, one branch is connected to a concentrate electromagnetic valve, the other branch is a concentrate reflow passage, and the concentrate reflow passage is connected between a pre-filter element and a raw water inlet; a control module controls a water incoming electromagnetic valve, a boost pump, the reflow electromagnetic valve and the concentrate electromagnetic valve to operate. After the pressure barrel is full, purified water in the pressure barrel flows into the RO filter element through the purified water reflow passage, concentrate in the RO filter element is replaced by the purified water, and the RO filter element is filled with the purified water.

Description

technical field

[0001] The invention belongs to the technical field of water purification equipment, in particular to a micro-waste water purifier. Background technique

[0002] my country is a water-scarce country. In order to solve the problem of wasting water resources, the China National Institute of Standardization formulated the "Water Efficiency Limits and Water Efficiency Grades of Reverse Osmosis Water Purifiers". Due to the improvement of water efficiency grades, micro-wastewater will gradually replace the previous wastewater The discharge is relatively large RO machine. Literally speaking, micro-waste water means less waste water. It is a technology applied to water purifiers. In the process of producing pure water, reverse osmosis water purifiers must discharge waste water (or called concentrated water, concentrated water) ). A reverse osmosis water purifier that discharges less waste water is called a "micro waste water purifier". The water-saving and emission...
