Background

The in-situ groundwater pollution remediation effect mainly lies in the establishment of groundwater three-dimensional circulation, in the double-filter-layer groundwater, the positive circulation is pumped and injected upwards, the reverse circulation is pumped and injected downwards, and the water filter pipe is required to be unblocked for a long time without scaling. In the existing filter pipes, no filter pipe specially used for draining water to stratum exists.

The study and the experiment of scholars have proved that no matter what kind of water filter pipe is made, the water filter pipe can be scaled at the gap after a long time, the efficiency of the water filter pipe becomes low or even blocked, the water filter pipe must be cleaned frequently, the technology for treating underground pollutants in the underground water circulating well generally needs 3 months of circulation treatment to reach good treatment effect, so the water filter pipe must be ensured not to be scaled and blocked for a long time.

The prior art has verified that in the plugging mechanism of the strainer, the important aspect is that solid suspended matters in water are precipitated and consolidated in the slit holes, and gradually increase to thicken and plug the strainer.
