摘要：

A lot of alum sludge (AS) and iron sludge (IS) produce in China from the drinking-water treatment works everyday. In this study, a series of batch experiments were conducted to investigate the phosphorus adsorption characteristics of alum sludge and iron sludge collected from two drinking-water treatment works in Zhengzhou, Henan, China using artificial Prich wastewater. The results indicated that the Langmuir adsorption isotherm is fit for the description of the phosphorus adsorption on the two kinds of sludges (R-2=0.9956 for AS, R-2=0.9975 for IS). Many factors including reaction temperature, initial pH and phosphorus concentration of artificial wastewater have effect on phosphorus adsorption processes; high temperature, acid environment and low phosphorus concentration are favorable for the enhanced phosphorus adsorption.
