新寨河流域矿井水对环境污染影响及其治理

Impact of Mine Water on Environmental Pollution in Xinzhai River Basin and Its Treatment

新寨河长期受到煤矿废水污染,污染源主要是开采煤矿和关闭的无主矿井等产生的污水,无主矿井酸性废水长期肆意流淌,成为新寨河的主要污染源之一。近年来,新寨河还受其源头下山镇土壤障碍层“含煤岩系”地层污染、小城镇生活污染以及农村面源污染等各种因素影响,河道水质污染严重,水体内观察不到有生命的物种,沿河寸草不生,整体呈黄色,出现了“锈水”“黄水”景象,河床沉积有黄褐色物质。本文主要研究新寨河流域酸性废水对环境污染的影响并提出治理方案。

Xinzhai River has been polluted by coal mine wastewater for a long time. The source of pollution is mainly the sewage produced by mining coal mines and closed ownerless mines. The acid wastewater of ownerless mines has been flowing freely for a long time, and it has become one of the main pollution sources of Xinzhai River. In recent years, the new village river also its source under the hills soil barriers “coal” formation pollution, small towns life pollution and rural non-point source pollution factors, river water pollution, water body observe the living species, no grass along the river, the whole yellow, the “rust” “yellow”, river bed deposition with tan material. This paper mainly studies the influence of acidic wastewater on environmental pollution and puts forward the treatment scheme.
