生态环保视域下煤矿区水环境污染治理技术研究

Study on water environment pollution treatment technology in coal mine area from the perspective of ecological environmental protection

煤矿开采给社会带来经济效益的同时对其周边水环境也造成严重破坏,为改善此问题,提出针对性的污染治理技术。首先,通过矿井水成分划分污染类型,利用水动力—化学—生物耦合策略明确水环境污染成因;然后,分析煤矿区水环境总容量,计算二维浅水水流与对流—扩散方程的守恒公式,使用过程线趋势差值法获取水环境污染通量,呈现煤矿区水环境污染水平;最后,就待治理区域实际情况,设计物理处理、水动力控制、原位处理与抽出处理4种技术,实现高质量水环境污染整治目标。实验分析表明,所提技术能有效改善煤矿区整体水质,具备极强的适用性与可靠性。

Coal mining has brought economic benefits to society,and has also caused serious damage to the surrounding water environment.In order to improve this problem,targeted pollution control technologies were proposed based on the perspective of ecological and environmental protection.Firstly,the pollution types were classified by the composition of mine water,and the causes of water environment pollution were determined by the hydrodynamic-chemical-biological coupling strategy;then,the total capacity of water environment in the coal mine area was analyzed,the conservation formula of two-dimensional shallow water flow and convection diffusion equation was calculated,and the process line trend difference method was used to obtain the water environment pollution flux,showing the water environment pollution level in the coal mine area;finally,according to the actual situation of the area to be treated,four technologies,namely physical treatment,hydrodynamic control,in-situ treatment and extraction treatment,were designed to achieve the goal of high quality water environmental pollution treatment.The experimental analysis shows that the proposed technology can effectively improve the overall water quality in the coal mine area,and has strong applicability and reliability.
