A reverse osmosis ultrafiltration water treatment device

Abstract

The invention discloses a reverse osmosis ultrafiltration water treatment device, which belongs to the technical field of sewage treatment and comprises a treatment box. An ultrafiltration unit and a reverse osmosis unit are arranged inside the treatment box. The ultrafiltration unit includes two vertically symmetrical The provided port closures, several ultrafiltration tubes are arranged between the two port closures, the middle part of the ultrafiltration tubes is fixedly connected with ultrafiltration membranes, and the top of the upper port closures is fixedly equipped with ultrafiltration tubes. The booster pump, the bottom of the port closure located below communicates with the reverse osmosis unit through a butt joint; the ultrafiltration unit of the present invention performs ultrafiltration operation on sewage through a plurality of independently arranged ultrafiltration tubes, and utilizes the port closure, Part of the ultrafiltration tubes are sealed, so that several ultrafiltration tubes can work alternately in batches, ensuring the filtering effect of ultrafiltration, and prolonging the continuous working time of the device at the same time.

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
