Description

These pollutants not only affect water quality, but may also enter the human body through the food chain, causing health problems and have a negative impact on the ecological balance of the soil. Moreover, commonly used groundwater resources are usually connected to surface water sources.

The bottom of the first filter cartridge 11 and the bottom of the second filter cartridge 13 are both connected with a sealing ring 24, and the diameter of the sealing ring 24 is greater than the diameter of the filter screen 10. It should be noted that when the first filter cartridge 11 and the second filter cartridge 13 move up and down, the guide sleeve 23 can guide them to prevent them from running off, and through the setting of the sealing ring 24, the gap between the first filter cartridge 11 and the second filter cartridge 13 can be sealed when they are against the reciprocating plate 903, so as to prevent sewage from leaking during the filtration process.
