淮河淮南段水污染状况及水质分析

Water Pollution Condition and Water Quality Analysis in Huainan Part of Huaihe River

采用综合污染指数法,选择了对淮河淮南段水质影响较大的溶解氧、高锰酸盐指数、生物需氧量等指标评价了淮河水质。结果表明,淮河淮南段枯水期水污染指数要明显高于丰水期和平水期,主要污染指标为氨氮、高锰酸盐指数、溶解氧,水质类型为Ⅳ类水到劣Ⅴ类水。在分析了污染物来源的基础上,提出了治理水污染的对策。

Water quality in Huainan part of Huaihe river is evaluated by comprehensive pollution index method according dissolved oxygen ete indexes. The resuhes indicate that water quality of low water period is worse than high - water period＇s.
