摘　　要：粉煤灰在降水淋滤的作用下可产生含氮量较高的淋滤水并进入地下,对地下水环境产生危害。为了研究粉煤灰在淋滤作用下污染物的释放规律,设计了一套粉煤灰淋溶实验装置。通过对收集的淋溶液进行测验,分析了淋滤水中NO-3-N、NO-2-N、NH+4-N的浓度随时间变化规律,并计算了累积释放量。根据实验结果,分析了实际情况下粉煤灰渗滤液对地下水环境的影响。研究结果对保护地下水资源有一定意义。Under the leaching action of rainfall, fly - ash can produce high N - content leachate entering underground and pol- lute water environment. In order to study the pollutant release law of fly - ash under the leaching action, a showering experiment device tor fly - ash was designed. Through measurement of the collected leaching solution, the variation law of NO3 - N ,NOr - N, NH4＇ - N concentration in the leaching solution was analyzed and the accumulated release volume was calculated. According to the experiment results, the influence of fly -ash on water environment in practical condition was analyzed. The analysis result has important significances to underground water protection.
