The deep well infusion techniques of deep well submersible pumps are extremely harmful to human health and the environment, and may minimize the risk of harm, as compared with other disposal technologies such as surface landfill, storage tank or incineration. Because it has the following advantages: Perfusion liquid stored in the deep geological layer, to avoid pollutants into the biosphere circulatory system; can reduce the atmospheric, water and shallow stratospheric environmental pressure; can replace the surface environmental capacity; when the environmental capacity is highly scarce And high processing costs, can reduce the cost of pollutant treatment; expand the scope of pollutant control technology selection. In all cases envisioned by the risk analysis, the risk of deep well infiltration is between one and one millionth of a million, and the safety factor is much higher than other waste disposal techniques.
