Abstract

The invention discloses a forward osmosis treatment system of saline-alkaline water, comprising an exchange tank wherein a frame for mounting a forward osmosis membrane is mounted; two sides of the forward osmosis membrane are used for introducing drawing liquid and raw liquid respectively, the bottom of the exchange tank is connected respectively with a drawing liquid incoming pipe and a raw liquid incoming pipe, the top of the exchange tank is provided with a drawing liquid outgoing pipe and a raw liquid outgoing pipe, the drawing liquid outgoing pipe is connected to a concentration adjusting tank, and the raw liquid outgoing pipe is connected to a raw liquid concentrating and precipitating tank; the exchange tank is internally provided with a plurality of first partitions to the drawing liquid side, the first partitions are provided with first through holes, the exchange tank is internally provided with a plurality of second partitions to the raw liquid side, the second partitions are provided with second through holes, and the first partitions and the second partitions are mutually staggered. The invention also discloses a treatment method of the forward osmosis treatment system of saline-alkaline water. The defects of the prior art can be improved, and osmosis efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of forward osmosis water and fertilizer integration, in particular to a forward osmosis treatment system for saline-alkali water and a treatment method thereof. Background technique [0002] Forward osmosis water and fertilizer integration is based on the principle of forward osmosis water treatment technology, using industrial wastewater, domestic wastewater, saline-alkali water, seawater, etc. Water treatment and utilization of new technologies have broad application prospects in wastewater treatment, groundwater treatment, seawater desalination, etc. The treated industrial wastewater, domestic wastewater, saline-alkali water, seawater, etc. can be directly used in water and fertilizer integrated irrigation systems. The driving solution of forward osmosis water and fertilizer integration is a mixed fertilizer solution. This driving solution not only has a high osmotic pressure, but also does not need to be...
