摘　　要：将生物接触氧化工艺应用于山东省小沙河污染河道的治理,采用人工接种闷曝法挂膜启动,经过高、中污染物含量进水驯化培养的生物膜,应用于处理低污染物含量的河道污水。结果表明,人工接种生物接触氧化法处理低含量河道污水是可行的,而且COD、氨氮、TP的去除率分别可达到57.4%、50.8%、85.7%,远远高于对照试验,说明在处理河道污水时,生物膜起决定作用。Biological contact oxidation process was employed for biofilm treatment of a polluted river way in Jining,Shandong.Using artificial inoculation biofilm growing method started experiment.The biomembrane which domesticated in environment of high concentrations of water and medial concentration of water treatmented low concentrations river wastewater.The results of experiment indicated that artificial inoculation biofilm growing method treatmented low concentrations river wastewater was feasible.The removal rates for COD,NH3-N,TP were 57.4%,50.8% and 85.7%,being far above than control experiment.It showed that biofilm played a decisive role.
