Abstract

The invention discloses a two-level reverse osmosis water treatment device with a backwash function. The two-level reverse osmosis water treatment device comprises a cartridge filter, a primary high-pressure pump, a primary reverse osmosis system, a secondary high pressure pump and a secondary reverse osmosis system, and also comprises a washing system, wherein the washing system comprises a washing box, a washing pump and a washing filter, the water outlet end of the washing filter is respectively connected with the water inlet end of the primary high pressure pump and the water inlet end of the secondary high pressure pump, and the outer outlet ends of the primary reverse osmosis system and the secondary reverse osmosis system are respectively connected with the washing box. When the reverse osmosis system needs to be washed, the washing system works, a washing liquid in the washing box is pumped out by the washing pump, then the washing liquid is respectively sent into the primary reverse osmosis system and the secondary reverse osmosis system after being treated by the washing filter, and the washing liquid flowing out from the primary reverse osmosis system and the secondary reverse osmosis system is then returned to the washing box to form circulating flushing, so that the water treatment system can be conveniently washed and maintained, the scaling of the reverse osmosis system can be avoided, and the reliability in long-term operation can be guaranteed.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to a two-stage reverse osmosis water treatment device with backwashing function. Background technique [0002] The existing reverse osmosis water treatment system does not have a self-flushing function, which makes the reverse osmosis membrane prone to fouling during long-term use, resulting in a decrease in the filtration performance of the reverse osmosis membrane and a decrease in the recovery rate of pure water. Contents of the invention [0003] In view of this, the object of the present invention is to provide a two-stage reverse osmosis water treatment device with backwash function to solve the problem of fouling of the reverse osmosis system during long-term use. [0004] The two-stage reverse osmosis water treatment device with backwashing function of the present invention includes a security filter, a first-stage high-pressure pump, a first-stage reverse osmosis system, a sec...
