摘要
根据2018年9月至2019年8月东风渠流入七里河处水质监测数据,建立东风渠水环境质量模糊综合评价模型,结果显示,受污染轻重程度的季节依次为:冬季<春季<夏季<秋季.通过计算评价因子的权重值得知,溶解氧(DO)、化学需氧量(COD)对水质的影响程度相对较大.这也是导致东风渠水体污染的主要污染物.
According to the monitoring data of water quality at the place where Dongfeng canal flows into Qili River from September 2018 to August 2019, the fuzzy comprehensive evaluation model of water environment quality of Dongfeng canal is established. The results show that the seasons of the degree of pollution are: Winter < Spring < Summer < Autumn. By calculating the weight of evaluation factors, it is known that DO and COD have a relatively large impact on water quality, which is also the case The main pollutants that cause water pollution in Dongfeng canal.
