摘要
某金矿废水氰化物在尾矿坝、环保坝及河流中的自然降解规律可以用负指数方程描述 .废水进入河流 A、河流 C后浓度降低的主导因素是河水的稀释作用 .通过计算研究 ,该金矿废水氰化物基本不对国际河流 F造成影响 .控制该金矿废水对 A、C2河污染的有效途径是增加循环用水量、降低环保坝水位以便减少废水渗水量 .
The degradation regularity of cyanide from a goldmine wastewater conform to negative exponential function in its tailing dam,regulation pond and the rivers.The main reason of cyanide decrease in streams A and C receiving the goldmine wastewater is dilution.The cyanide from the goldmine wastewater should not affect the international river F.Available way of decreasing the cyanide pollution on the streams is to increase the rate of circulating water so that lower the wastewater level in the regulating pond and decrease the amount of leakage of the wastewater.
