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.
