摘要
采用多元线性拟合的方法,结合南宁市竹排冲河道水质监测断面数据,选取CODCr,DO,NH3-N有机污染指标与Fe,Mn无机污染指标,建立了适合南宁市竹排冲河道水体黑臭的评价模型:I=0.050 3[CODCr]+0.257 6[NH3-N]-2.304 9[DO]+1.239 4[Fe]+2.770 0[Mn]+14.407 8,并对模型进行校验,结果表明:该模型适用于南宁市竹排冲河道水体黑臭程度的评价,为建立南宁市河道黑臭预警系统提供理论依据.
In this paper,several major parameters（such as CODCr,DO,NH3-N,Fe and Mn etc.） in Nanning Zhupai Creek were used to correlate with the black-odour index.The results showed that CODCr,NH3-N,DO,Fe,Mn were the major factors to affect the black-odour index.Based on a set of data,a predict model for the black-odour index in Zhupai Creek was developed,i.e., I=0.050 3＋0.257 6-2.304 9＋1.239 4＋2.770 0＋14.407 8.The above model provides not only a good evaluation tool for the black-odour level in Zhupai Creek,but also the theoretical basis for building early warning monitoring system in the black-odor in Nanninig urban rivers.
