Abstract:
The surface water pollution is a serious problem.To master the water pollution source and control the total amount effectively is the technical base for achieving regulation of water pollution source. It also can provide the necessary technical support for the surface water pollution control.In this paper, the surface water pollution source methods are summarized both in China and abroad. The research and application progress of receptor model which is the more effective source apportionment model technology is discussed in detail,such as ratio method,fingerprint method,chemical mass balance method and multivariate statistical model. The existing problems and application prospect of surface water pollution source analysis technology are reviewed and prospected.It points out that the main problems of current source of water environment analytical technology is: The research objective of source parse pollutants are relatively limited; The lack of complete technical system and the limitations of existing technology limits the rationalization of the source parse result; The incompleting of pollution source component spectrum and the existing monitoring means restrict the deep of source analytical research. It also puts forward that the improvement and optimization for the existing technology as well as the multivariate analysis and coupling application are becoming a source of parsing technology development trend. The geographic information technology, engineering mathematics methods and the development of analysis monitoring technology will write a new page for water environment pollution source analytical research.
