The Spread And Movement Of Pollutants In The Groundwater And The Harness

The harness and resume of the polluted groundwater had undergone a long time from the identification resume in 1970s to the predicative prevention in 1980s, till the present harness and resume based on the risk evaluation. Even now, the groundwater still couldn't be harnessed and resumed by the definite means. Systematic research on the spread and movement of pollutants in the groundwater will do help a lot in the harness of the pollution.This thesis intends to give a systematic and classified research on the basis of the representative reactions produced by several different kinds of pollutants, derive the movements of all kinds of pollutants through dispersion equation, provide both the quantitative and qualitative equations, and the means of the selection of parameter. Different harnesses to different pollutants are present including reconstructive technologies based on the pull-out, the monitor of natural decay, and the restoration of the original place which includes osmosis reaction reconstruction technology and air injection reconstruction technology, and, meanwhile, both the merits and flaws of these reconstructive technologies are compared synthetically.This thesis targets to make the complex pollution and harness of the groundwater formulaic, simplified and theoretic in order to assist common technicians and scholars to infer. This thesis is expected to afford the theoretic support to both protection and harness of the groundwater and benefit the researches of the groundwater inland.
