摘　　要：以三相生物流化床处理焦化废水工程中污泥为研究对象,对各工艺段中污泥进行了红外光谱分析、粒径分析和扫描电镜分析。研究发现,好氧工艺段污泥粒径普遍比厌氧或者水解工艺段粒径大,缺氧段污泥表面更加粗糙,有利于污染物的吸附。In three-phase biological fluidized bed sludge treatment of coking wastewater, the sludge in the process was investigated by laser particle sizer,scanning electron microscopy analysis and infrared spectroscopy. The study found that the sludge particle of the aerobic process is larger than that of the anaerobic and hydrolysis process. The surface of the hydrolysis sludge is advantageous to the adsorption of pollutants because of the rough surface.
