贵州松桃县某水库锰污染现状及成因分析

Analysis on Manganese Pollution Status and Cause of a Reservoir in Songtao County,Guizhou Province

松桃县某水库于2016年10月建成蓄水,2019年4月发现水库底层水体锰含量超标。通过对比分析水库上、下游及库区内不同位置水体、底泥的锰含量数据,查明了水库的锰污染现状:重污染水体和底泥分布在水库中下游15m以深的中央条状地带。探讨了该水库锰污染的原因,分析认为导致水库被污染的原因是东北部电解锰尾渣库渗滤液泄漏所致。

A reservoir in Songtao county was built to store water in October 2016,it was found that the manganese content in the water body at the bottom of the reservoir exceeded the standard in april 2019.Through the contrast analysis on the manganese content data of water body and sediment in the upstream and downstream and different locations in the reservoir area of a reservoir.The current situation of manganese pollution in the reservoir is found out:the heavily polluted water body and sediment are distributed in the central strip more than 15m deep in the middle and lower reaches of the reservoir.The causes of manganese pollution in reservoir are discussed:the reason for the pollution of the reservoir is the leakage of leachate from the Electrolytic Manganese Tailings Reservoir in the northeast.
