摘要
选取大庆地表水系统中具有代表性的10个监测点,对水质的pH值、CODMn、BOD5、TP、NH3-N、悬浮物和石油烃类物质7项理化指标的监测数据进行因子和聚类分析。分析结果表明,大庆地表水系统中的主要饮用水源的水质环境尚清洁,渔业用水水源的水质已受到轻度污染,城市生活废水与有机工业污水可能是造成水质污染的主要原因。
10 representative monitoring points of surface water quality were chosen in Daqing region and 7 physical and chemical indicators including pH、CODMn、BOD5、TP、NH3-N、suspended solids and oil were picked up to make the factor analysis and cluster analysis.The research showed that in surface water quality of Daqing region,the water quality of drinking water sources was fine,but the water quality for fishery was polluted lightly.The pollution of water quality was mainly caused by municipal wastewater and organic industrial wastewater.
