Reverse osmosis ultrafiltration water treatment device

Abstract

The invention discloses a reverse osmosis ultrafiltration water treatment device, and belongs to the technical field of sewage treatment. The reverse osmosis ultrafiltration water treatment device comprises a treatment box, wherein an ultrafiltration unit and a reverse osmosis unit are arranged in the treatment box, the ultrafiltration unit comprises two port sealing pieces which are symmetrically arranged up and down, a plurality of ultrafiltration pipes are arranged between the two port sealing pieces, an ultrafiltration membrane is fixedly connected to the middle of the ultrafiltration pipe, an ultrafiltration booster pump is fixedly mounted at the top of the upper port sealing piece, and the bottom of the lower port sealing piece is communicated with the reverse osmosis unit through a butt joint pipe. According to the ultrafiltration unit disclosed by the invention, the ultrafiltration operation is performed on sewage through the plurality of independently arranged ultrafiltration pipes, and part of the ultrafiltration pipes are sealed by utilizing the port sealing pieces, so that the plurality of ultrafiltration pipes can alternately work in batches, the ultrafiltration effect is ensured, and meanwhile, the continuous working time of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a reverse osmosis ultrafiltration water treatment device. Background technique [0002] Ultrafiltration is a membrane separation technology. The filtration process is a solution separation process based on the pressure difference on both sides of the membrane and the principle of mechanical separation. Reverse osmosis is the use of sufficient pressure to allow the solvent in the solution to pass through the reverse osmosis membrane and then separated, and the direction is opposite to the direction of osmosis. In the actual water treatment process, various membrane technologies such as ultrafiltration and reverse osmosis are often used in combination to achieve the purpose of efficiently treating pollutants. [0003] Such as figure 1 Shown is a combination of ultrafiltration and reverse osmosis water purification equipment, which processes sewage through an ultrafiltrat...

AI Technical Summary

Problems solved by technology

For water treatment equipment with this structure, since the ultrafiltration mechanism is arranged at the front end of the reverse osmosis mechanism, the speed at which impurities such as colloids accumulate on the ultrafiltration membrane is much faster than that of the reverse osmosis membrane. Inconvenient to use due to frequent cleaning or replacement operations
