Geology treatment method for groundwater pollution at upstream of groundwater system
The invention discloses a geoscience treatment method for groundwater pollution on the upstream of a groundwater system. The geoscience treatment method comprises the steps that S1, pollution investigation is conducted, specifically, the groundwater flow direction at a pollution source, the position of a waterproof bottom plate and the lateral boundary of a pollution plume are investigated; s2, curtain construction is conducted, specifically, an interception curtain is built on the downstream of the flowing direction of underground water; s3, pump drainage well construction, wherein a sewage pump drainage well is built between the pollution source and the interception curtain; and S4, sewage pumping and drainage, wherein the polluted underground water in the pumping and drainage well is pumped out through a pumping system to be treated. The purpose of intercepting and closing polluted underground water is achieved by building an intercepting curtain at the position, close to a pollution source, of the underground water flowing downstream, the water level in a pumping and draining well can be continuously increased along with increase of the closed polluted underground water amount, sewage stored in the pumping and draining well is pumped out for treatment, the pollutant concentration of a downstream pollution acceptor is practically reduced, and the pollution of the downstream pollution acceptor is reduced. The problem of expensive and continuous water treatment investment at the tail end can be effectively reduced or even eliminated, and the burden of environmental governance is practically relieved.
本发明公开了一种地下水系统上游的地下水污染地学治理方法，其包括：S1、污染调查：调查污染源处的地下水流向、隔水底板的位置以及污染羽的侧向边界；S2、帷幕施工：在地下水的流向下游，建设拦截帷幕；S3、抽排井施工：在污染源和拦截帷幕之间建设污水抽排井；S4、污水抽排：将抽排井内的污染地下水通过抽水系统抽出进行处理。通过在地下水流向下游且靠近污染源的位置建设拦截帷幕，达到拦截封闭污染地下水的目的，随着封闭污染地下水水量的增加，抽排井内的水位也会不断上升，通过将抽排井内蓄存的污水抽出处理，以切实减轻下游污染受体的污染物浓度，其能够有效减小甚至清除末端高昂持续的水处理投入问题，切实减轻环境治理的负担。
