[0002] Geothermal water refers to groundwater whose surrounding rock temperature is higher than the observation depth. The temperature at which water starts to boil under a certain pressure is called the saturation temperature. The deeper the geothermal water is buried, the higher the static pressure it is subjected to, and the higher the corresponding saturation temperature. Geothermal tail water often contains impurities, particulate matter and other harmful substances. If it is discharged directly, it will cause pollution to the environment. Therefore, the geothermal tail water needs to be filtered before reinjection.

[0003] However, there are still some problems when using the existing geothermal tail water recharge filtration device:
