In actual use, the bottle washing water that needs to be purified is first introduced into the water collection tank 1 for precipitation to remove part of the precipitated impurities. Through the coarse filtration of the coarse filter device 2, impurities such as paper dust and glass in the bottle washing water are removed. Then, it is pumped into the fine filtration device 4 through the booster pump 3. Generally, a 0.2µ ultrafiltration membrane filtration device can be selected as a fine filtration device, because the 0.2µ ultrafiltration membrane filtration device has a higher interception efficiency. The ultrafiltration membrane performs high-efficiency liquid/solid separation with a separation accuracy of 0.2 µm and a clarity that reaches the standard of tap water. Next, the bottle-washing water enters the sterilization device 5 for sterilization. In general, a stepless ultraviolet light sterilization device can be selected, because the stepless ultraviolet light sterilization device can quickly and effectively eliminate bacteria and realize sterile water production. And it will not cause other pollution to the water and surroundings. Finally, the water discharged from the sterilizing device 5 flows to the terminal water tank 6, which realizes the recycling of the bottle washing water after recovery.

In addition, in order to prevent the reverse flow of the water flow, a one-way valve 43 can be selected between the booster water pump 3 and the fine filter device 4, and the flow direction of the one-way valve 43 is to flow from the booster water pump 3 to the fine filter device 4 . By controlling the direction of water flow, the purification process of bottle washing water can be made more efficient and controllable.

While the bottle washing water is recycled and purified, it is also necessary to monitor the bottle washing water. Once the water quality is found to be unqualified, the circulating water with unqualified water quality should be drained, and new tap water should be injected to recycle and purify to ensure the bottle washing. water quality.
