The invention discloses a reverse osmosis purification unit which comprises a plurality of reverse osmosis filter elements, wherein the concentrated liquid outlet of at least one reverse osmosis filter element is connected with the stoste inlet of another reverse osmosis filter element. When the reverse osmosis purification unit works, a concentrated liquid discharged by at least one reverse osmosis filter element enters another reverse osmosis filter element and is taken as stoste to be further separated. Obviously, according to the reverse osmosis purification unit, the directly discharged concentrated liquid is reduced because the stoste is separated, so that the utilization rate of the stoste is increased. Therefore, the recycling rate of the reverse osmosis purification unit is high. Furthermore, the number of shunting branches of the stoste with the same flow is reduced under the condition that the reverse osmosis purification unit comprises a fixed number of the reverse osmosis filter elements, and the unit liquid flow on a reverse osmosis film of each reverse osmosis filter element is increased, so that the service life of each reverse osmosis filter element is prolonged. The invention also discloses a reverse osmosis purification system comprising the reverse osmosis purification unit.
Description
technical field [0001] The invention relates to the technical field of purification devices, in particular to a reverse osmosis purification unit. The present invention also relates to a reverse osmosis purification system comprising the above reverse osmosis purification unit. Background technique [0002] Reverse osmosis purification technology is a membrane separation operation that uses pressure difference as the driving force to separate the solvent from the solution. This technology applies pressure to the raw solution on one side of the reverse osmosis membrane. When the pressure exceeds its osmotic pressure, the solvent in the raw solution Reverse osmosis will be performed against the direction of natural osmosis, so that the permeated solvent is obtained on the low pressure side of the reverse osmosis membrane, that is, the permeate, and the concentrated solution is obtained on the high pressure side, that is, the concentrate. The core working part of this technolo...
