摘要:
对松花江流域黑龙江控制区段13个监测断面不同水期的水质指标进行主成分分析，以鉴别主要的污染源，进而提出有针对性的水污染控制对策。结果表明，BOD5、COD、TP、TN为主要污染指标，合计贡献率为49.529%，首要污染源为生活污水与农业废水。第二大污染指标主要为石油类、阴离子表面活性剂、氰化物，主要来源于工业废水。总污染最严重的主要是阿什河口内平水期与龙安桥平水期。龙安桥平水期等对应的河流区段受生活污水及农业废水污染较为严重,苗家平水期等对应的河流区段受工业污染较为严重。
Abstract:
Principal component analysis of the water quality indicators of 13 monitoring sections in Heilongjiang control section of the Songhua River Basin in different water periods was carried out to identify the main pollution sources, and then targeted water pollution control countermeasures were proposed. The results showed that BOD5, COD, TP and TN were the main pollution indicators, with a total contribution rate of 49.529%. The primary pollution sources were domestic sewage and agricultural sewage. The second largest pollution indexes were petroleum, anionic surfactants and cyanide from industrial wastewater. The most serious pollution was mainly in Ash River Estuary and Longan Bridge during normal water period. Longan Bridge during normal water period was seriously polluted by domestic sewage and agricultural sewage. Miaojia during normal water period was seriously polluted by industrial wastewater.
