| 摘 要： | 针对西安金盆水库2017年汛期出现的锰浓度超标问题,对水库上游至主库区沿程多个监测点垂向锰浓度及其赋存形态进行监测,研究暴雨径流对水中锰含量的影响以及径流中锰的形态,估算单次典型暴雨径流过程水库水体锰的汇入、输出与沉积量,根据实测数据与计算结果,从运行调度角度提出了暴雨时期高浊、高负荷径流入库的规避方案.结果表明,强降雨过程引起的高浊径流汇入显著增加了西安金盆水库水体总锰浓度,导致水库水质严重恶化,2017年10月12日至2017年10月14日单次降雨径流总锰的输入负荷为9. 11 t,泄洪和出水输出的总锰为6. 22 t,净沉积量(锰)为1. 47 t.水库上游沿程水体锰含量及形态变化表明,连续降雨过程对土壤的冲刷和侵蚀作用导致大量颗粒态污染物随径流汇入水体,占水体中总锰的质量分数大于70%,铁锰氧化物结合态为其主要形态.通过与不同粒径范围的颗粒进行相关性分析,颗粒态锰粒径约为2～20μm.暴雨径流入库时期采取泄洪排浊的措施可以有效减小锰的污染负荷,降低供水安全风险.
