Reverse osmosis wastewater recycling device

Abstract

The invention discloses a reverse osmosis wastewater recycling device, and belongs to the field of water treatment. The device includes a reverse-filtration water purifier and a water storage tank, wherein a purified water outlet and a concentrated water outlet are formed in the reverse-filtration water purifier; a communicating pipe is communicated between the concentrated water outlet and the water storage tank; the bottom end of the water storage tank communicates with a main pipe; a valve is arranged on the outer wall of the main pipe; the end, away from the water storage tank, of the mainpipe communicates with a U-shaped flow dividing pipe; one end of the flow dividing pipe is fixedly connected with a first faucet; a first water tank is arranged on the lower side of the first faucet;the bottom end of the first water tank communicates with a first drain pipe; the other end of the flow dividing pipe is fixedly connected with a second faucet, a second water tank is arranged on thelower side of the second faucet, and an L-shaped transmission groove is formed in the outer wall of one side of the second water tank. Secondary utilization of reverse filtration waste water can be achieved, and used water can be filtered and used again.

Description

technical field [0001] The invention relates to the field of water treatment, and more specifically relates to a reverse osmosis wastewater recycling device. Background technique [0002] Reverse osmosis is a process that uses a pressure higher than the osmotic pressure as a driving force to separate water molecules from solutes from water by using the selective permeability of selective membranes that can only pass through water but not solutes. The wastewater ratio of filtered water is 1:1 for some, and 1:3 for some. A large amount of wastewater will appear in the process of filtering water, resulting in a waste of water resources. However, the existing method is to filter the wastewater again through a reverse osmosis membrane. If If the wastewater from the reverse osmosis water purifier is returned to the water inlet of the reverse osmosis water purifier, only salt will flow into the reverse osmosis water purifier system, and no salt will be discharged, which means that ...
