By mixing the secondary reverse osmosis concentrate produced by the secondary reverse osmosis system 40 with the ultrafiltration concentrate, the secondary reverse osmosis concentrate and the ultrafiltration concentrate are treated together by the primary reverse osmosis system 30, instead of directly discharging the secondary reverse osmosis concentrate, thereby effectively improving the utilization rate of water resources. By mixing the EDI concentrate produced by the EDI system 50 with the first-stage reverse osmosis concentrate, the EDI concentrate and the first-stage reverse osmosis concentrate are treated together by the second-stage reverse osmosis system 40, instead of directly discharging the EDI concentrate, thereby effectively improving the utilization rate of water resources and greatly reducing the waste of water resources.
As shown in fig. 2, the reclaimed water system for the pure water production system further comprises a plurality of connecting pipes 60, one side of the connecting pipe 60 has a water inlet end 61, and the other side of the connecting pipe 60 has a water outlet end 62 and a water return end 63.

After the EDI concentrated water flows back to the first-stage reverse osmosis water tank 31 from the water return end 63, the EDI concentrated water can be mixed with the first-stage reverse osmosis produced water in the first-stage reverse osmosis water tank 31 and then enters the second-stage reverse osmosis system 40.
Optionally, a valve assembly 70 is provided on the connecting line 60, the valve assembly 70 being disposed between the water inlet end 61 and the water outlet end 62.

Specifically, the reclaimed water system for the pure water preparation system further comprises a pump station spray water tank 80, and the ultrafiltration system 20 is connected with the pump station spray water tank 80, so that ultrafiltration concentrated water flows into the pump station spray water tank 80, and the ultrafiltration concentrated water is reclaimed to the reclaimed water tank 80 for pump station spray water tank 80 with low water quality requirements, so that the reclaimed water can be used for subsequent production and spray.
Specifically, the secondary reverse osmosis system 40 includes a secondary reverse osmosis water tank 41, and secondary reverse osmosis produced water enters the EDI system 50 from the secondary reverse osmosis water tank 41. The EDI system 50 includes an EDI water tank 51 to contain EDI-produced water.
Of course, the primary reverse osmosis system 30 may also be connected to the pump station spray water tank 80 such that the primary reverse osmosis concentrate water is utilized in the pump station spray water tank 80.
When the ultrafiltration system 20 is used to treat raw water, only visible impurities, particulate matters, and the like are treated, and the conductivity of raw water is not changed. And after passing through the primary reverse osmosis system 30, the conductivity of the primary reverse osmosis produced water is drastically reduced compared with that of the raw water, and the primary reverse osmosis concentrated water conductivity is higher than that of the raw water. The concentrated water produced by the ultrafiltration system 20 and the first stage reverse osmosis system 30 is not suitable for recycling to raw water, so that the pump station spray water tank 80 with low requirements on water quality can be recycled.
The conductivity of the primary reverse osmosis produced water is below 10% of that of the raw water, and after the primary reverse osmosis produced water passes through the secondary reverse osmosis system 40, the conductivity of the secondary reverse osmosis concentrated water is far lower than that of the raw water. The primary reverse osmosis produced water directly enters the ultrafiltration water tank 21. After the second-stage reverse osmosis concentrated water returns to the ultrafiltration water tank 21, the second-stage reverse osmosis concentrated water is mixed with ultrafiltration produced water, so that the quality of the ultrafiltration produced water is improved, and the recovery rate of water resources is improved. The same principle applies to the return of the EDI concentrate to the primary reverse osmosis water tank 31. Meanwhile, for convenience in maintenance, a concentrated water discharge function is reserved.
In one embodiment shown in fig. 1, the method has the advantages that the redundant storage device is not added, the operation is simple and convenient, the water quality is improved on the original basis, the service life of the water making equipment is prolonged, the recovery rate of water resources is improved under the condition of guaranteeing the water quality of produced water, and the water resources are not wasted. The trend of the concentrated water can be determined according to the opening and closing of the valve assembly 70, so that the link of the concentrated water discharge is reserved for the convenience of maintenance.
It should be noted that, to recover the concentrate of the corresponding system, it is first confirmed that the conductivity of the second-stage reverse osmosis concentrate is lower than that of the raw water and the ultrafiltration product water, and that the conductivity of the EDI concentrate is lower than that of the first-stage reverse osmosis product water; finally, it is determined how the ultrafiltration concentrate and the first stage reverse osmosis concentrate reach the pump station spray water tank 80, and how the second stage reverse osmosis concentrate returns to the ultrafiltration water tank 21 and how the EDI concentrate returns to the first stage reverse osmosis water tank 31. In the running process, the concentrated water has certain pressure, so the concentrated water can automatically return to the corresponding water tank without adding a pump.
From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:
1. the secondary reverse osmosis concentrated water produced by the secondary reverse osmosis system 40 is mixed with the ultrafiltration concentrated water, so that the secondary reverse osmosis concentrated water and the ultrafiltration concentrated water are treated by the primary reverse osmosis system 30 together, and the secondary reverse osmosis concentrated water is not directly discharged, thereby effectively improving the utilization rate of water resources.
2. The EDI concentrate produced by the EDI system 50 is mixed with the first-stage reverse osmosis concentrate, so that the EDI concentrate and the first-stage reverse osmosis concentrate are treated together by the second-stage reverse osmosis system 40, instead of directly discharging the EDI concentrate, the utilization rate of water resources is effectively improved, and the water resource waste is greatly reduced.
