And a sewage drain is arranged at a position close to the outlet.

The pump 2 is added to pump out water in the water well 1, and the water is sent to the sand filter 3 for coarse filtration. Most of the solid particles will be filtered out. Then sent to a quartz sand filter 4 from the bottom to intercept organic matters, colloid particles, microorganisms and partial heavy metal ions in the water and reduce turbidity. From the bottom, a manganese sand filter 5 is then fed for further removal of suspended matter and also mixed solid particles. Then the waste water is sent into an activated carbon filter 6 from the bottom to adsorb ions, organic matters, pigments, peculiar smell and the like which cannot be removed before; then, the mixture is fed into an ion exchange device 7 from the bottom to adjust the hardness.

After that, according to the requirements of crops, a pH value adjusting device can be arranged behind the ion exchange device 7 to adjust the pH value of the purified water. After the ion exchange device 7, a water tank 8 may be added for temporarily storing the purified water, but the water tank 8 is not essential.
