蓄水水库污染特征分析及污染风险预测研究

Analysis of Pollution Characteristics and Prediction of Pollution Risk in Water Storage Reservoirs

蓄水水库污染问题是阻碍其发展的关键因素之一,故提出蓄水水库污染特征分析及污染风险预测方法。在蓄水水库中布设多个监测点位,按照每月一次频率采集水样并监测污染数据,以此为基础,确定蓄水水库污染特征参数。采用单因子污染指数法与内梅罗综合污染指数法预测水体污染指数,应用地累积指数法预测沉积物污染风险指数,联合计算获取蓄水水库综合污染指数,并制定蓄水水库污染风险等级判定规则。实验数据显示:应用该方法获得的蓄水水库污染特征参数含量结果与实际数值保持一致,污染风险预测结果与实际结果相同。

The pollution of water storage reservoirs is one of the key factors hindering their development,so a method for analyzing the pollution characteristics of water storage reservoirs and predicting pollution risks is proposed.Multiple monitoring points are set up in the water storage reservoir,and water samples are collected monthly to monitor pollution data.Based on this,the pollution characteristic parameters of the water storage reservoi is analyzed using the single factor pollution index method and the Nemero comprehensive pollution index method to predict the water pollution index.The land accumulation index method is used to predict the sediment pollution risk index.The study jointly calculates the comprehensive pollution index of the storage reservoir,and formulates rules for determining the pollution risk level of the storage reservoir.The experimental data shows that the pollution characteristic parameter content obtained by applying this method is consistent with the actual values,and the pollution risk prediction results are consistent with the actual results.
