摘要: 为了了解宿鸭湖水库的环境生态状况,根据其2009—2015年的水质监测资料和功能区水质要求,采用单因子水质标识指数法、综合污染指数法、有机污染指数法对其水环境质量予以评估。结果表明,TP、TN是该水库的主要污染因子,其次是COD、BOD5和石油类的影响,这几项因子的共同作用致使水库仅有4个月水质合格,有60个月为劣V类水,年均水质始终为污染状态。从综合污染角度,该水库只有15个月水质合格,其他月份则为污染状态,其中有28个月是重度污染,这导致其年均水质和水期绝大部分水质为污染甚至重度污染状态。从有机污染角度,水库有3个月为轻度有机污染,其他月份污染指数在2.0以下,这使得其年均和水期水质基本在较好与一般之间变化。

Abstract: Three methods were applied to water quality assessment for the Suyahu reservoir, including the single factor water quality identification index, comprehensive pollution index and organic pollution index methods. The assessment was based on water quality data from 2009 to 2015 in addition to water quality requirements. The results suggested that TP and TN were the main pollution factors and the effect of COD, BOD5 and oil class were secondly in the reservoir, it was the combination of the factors that caused the reservoir water quality only four months qualified, sixty months in bad class water and annual water quality always in pollution; From the perspective of comprehensive pollution, there was only fifteen months that water quality qualified, the rest period in pollution with twenty-eight months in severe polluted, which made its water quality of annual and most of water season was in pollution even severe pollution; From the perspective of organic pollution, there was three months in mild organic pollution for the reservoir and organic pollution index was less than 2.0 in other months, which resulted in its water quality of annual and water season changed between normal and better.

Key words: Suyahu reservoir, single factor water quality identification index, comprehensive pollution index, organic pollution index, assessment
