Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Examples

As shown in fig. 1-2, a device for concentrating and recycling garlic wastewater comprises a coarse filtration system 1, wherein a precipitation system 2, a fine filtration system 3 and a forward osmosis device 4 are sequentially arranged on one side of the coarse filtration system 1, the forward osmosis device 4 is further connected with a multistage reverse osmosis device 5 arranged on one side of the forward filtration system, the upper end of the forward osmosis device 4 is respectively connected with a garlic concentrated solution outlet 6 and the multistage reverse osmosis device 5, the lower part of the other end of the multistage reverse osmosis device 5, which is far away from the forward osmosis device 4, is provided with a produced water recycling water outlet 7, and the other end of the multistage reverse osmosis device 5 is connected with the lower part of the forward osmosis device 4.

Preferably, a stainless steel filter screen is arranged in the coarse filtration system 1, and the stainless steel filter screen is used for filtering large-particle substances in the original water body.
