摘　　要：为筛选出合适的滴水湖补充水的处理工艺,开展了“生物接触氧化+气浮”(工艺1)和“生物滤池+沉淀”(工艺2)两种组合工艺处理地表源水的中试研究(规模为20 m3/h)。结果表明,生物接触氧化池对藻类、叶绿素a和氨氮的去除效果比生物滤池好,但二者对浊度、总磷、CODMn的去除效果相差不大;工艺1去除浊度、藻类、叶绿素a、总磷、氨氮和CODMn的效果较工艺2好,且对污染物的去除效果受混凝剂投加量的影响较小。To select suitable supplementary water treatment process for Dishui Lake, pilot-scale test using biological contact oxidation/air flotation process and biological filter/inclined-tube sedimentation process with influx of 20 m^3/h to treat surface water was ca,Tied out. The results show that the biological contact oxidation, whose efficiency in the removing of turbidity, TP and CODM. is similar to biological filter＇ s, has advantage over biological filter in the removing of algae, chlorophyll-a and NH3 - N. Biological contact oxidation/air flotation process has advantage over biological filter/inclined-tube sedimentation process in the removing of turbidity, algae, chlorophyll-a, TP , NH3 - N and CODMn. In addition, the effect of flocculation agent dosage on the biological contact oxidation/air flotation process is relatively less.
