It is arranged in series with two-pass reverse osmosis module, the concentrated water that the process of first-stage reverse osmosis module is obtained is obtained Jing after the process of two-pass reverse osmosis module
To pure water, the concentrated water that the process of two-pass reverse osmosis module is obtained further is processed into untreated water tank；Counter-infiltration module is obtained
Pure water is reclaimed.
Further, the heat reclamation device and resin soften and arrange between tower untreated water tank and water pump, into described
The water of counter-infiltration module is pumped into by high-pressure hydraulic pump.
Further, the ratio of the film group number of described first-stage reverse osmosis module and the film group number of two-pass reverse osmosis module is
2:1。
Further, the inside module of described first-stage reverse osmosis module is using structure in parallel.
Further, the reverse osmosis membrane aperture of described first-stage reverse osmosis module is 0.4nm, and liquid temp is extracted during filtration
For 30 DEG C, feedwater pressure is 1.1MPa.
