摘要
距离平果铝赤泥堆场淋洗水收集池下游约600 m的S36地下河流动天窗地下水中出现了与赤泥回水pH、强碱等水质敏感因子含量超标情况,文章通过分析赤泥堆场与其回水池建设、运营情况,以及回水池区域地质与水文地质、回水池地勘资料,判定渗漏点在回水池,通过对回水池的赤泥回水进行抽干排查,发现了疑似漏点,采用在线自动监测荧光示踪仪(GGUN-FL30)进行示踪试验,验证了回水池疑似漏点为引起S36水点水质超标的渗漏点。对渗漏点进行试堵处理后,S36水点的pH等水质敏感因子回到了本底值,从而进一步验证了该渗漏点为回水池目前存在的发生渗漏的点。
The content of water quality sensitive factors such as pH and strong alkali in the groundwater of S36 underground river flowing skylight,which is about 600 m away from the downstream of the leaching water collection tank of Pingguo aluminum plant red mud yard exceeds the standard.By analyzing the construction and operation of the red mud yard and its water recycling tank,as well as the geological and hydrogeological data of the water recycling tank area and the geological survey data of the water recycling tank,it is determined that the leakage point is in the water recycling tank.Through the drainage and investigation of the red mud recycling water in the water recycling tank,the suspected leakage point is found,and the on-line automatic monitoring fluorescence tracer(GGUN-FL30)is used for tracer test.It is verified that the suspected leakage point in the water recycling tank is the leakage point that causes the water quality of S36 water point to exceed the standard.After the trial plugging treatment of the leakage point,the water quality sensitive factors such as pH of the S36 water point returned to the background value,which further verified that the leakage point is the current leakage point in the water recycling tank.
