Irrigation Security of Reclaimed Water Based on Water Quality in Beijing
Reclaimed water is the valid approach to solve the problem of water resource scarcity and prevent secondary pollution. Based on the case study of Gaobeidian sewage treatment plant of Beijing, the security of agricultural environment of reclaimed water irrigation was studied by statistic analysis of water quality and irrigation experiment. With the case study of Gaobeidian Sewage Treatment Plant of Beijing, qualities of reclaimed water and the rules of change were studied. The method of principal component analysis (PCA) was used to extract the main indices that can delegate the change of water quality. It was proved that coliform group, total salt, total N, LAS and heavy metal affect the irrigation security mainly and the water quality indexes was affected diversely by the factor of season.
