摘　　要：以高氨氮高有机物污染河网原水为研究对象,考察集生物预处理、常规处理、深度处理于一体的组合处理工艺对于原水特征污染物的去除效能.试验发现,生物预处理和生物活性炭对氨氮去除贡献较大,温度是影响氨氮去除效果的一个重要因素;对于有机物,组合处理工艺对CODMn的去除率比TOC高,混凝沉淀和生物活性炭是主要的去除单元;混凝沉淀对浊度和铁的平均去除率大于95%,具有良好的去除效果,对于锰的平均去除率达到50.9%.A full scale study was conducted to evaluate the removal efficiency of combined treatment process,which consists of biological pretreatment,conventional treatment and advanced treatment,on contaminated raw water with high ammonia nitrogen and high organic pollutants.It was found that the ammonia nitrogen was mostly removed by biological pretreatment and biological activated carbon,and the temperature of water was an important factor.The removal efficiency of combined treatment process on CODMn was higher than TOC.Sedimentation and biological activated carbon were two important processes for the removal of organic pollutants.Turbidity and iron ion were removed effectively by sedimentation,and the average removal rates were larger than 95%.The removal rate of manganese ion by sedimentation was 50.9%.
