摘　　要：使用固定剂将颗粒状活性炭固定在盘片上,制成了一种新型生物转盘盘片———活性炭生物转盘盘片。采用一级微型生物转盘法处理模拟化工废水,对比了活性炭、石英砂、聚丙烯3种生物转盘的处理效果。实验结果表明,活性炭生物转盘对COD的去除效果好于其他两种转盘。在进水COD为600m g/L、水力停留时间为6h、盘片转速为4r/m in的条件下,活性炭生物转盘对COD的去除率可达71.3%。此外,活性炭生物转盘还有较强的耐有机负荷冲击能力。在废水处理过程中,活性炭仅在挂膜的前7天起吸附作用,挂膜成功后生物降解起主导作用。Active carbon biodisk, a new type of biodisk, was manufactured by fixing granular active carbon on the disk with fixative. Stimulated chemical wastewater was treated by a single stage biodisk process. The treatment effects by active carbon biodisk, quartzite biodisk and polypropylene biodisk were compared. The experimental results indicate that active carbon biodisk has better COD removal than the other two. Under the conditions of influent COD 600 mg/L, HRT 6 h and rotary speed 4 r/min,the COD removal rate by active carbon biodisk is 71.3%. In addition,active carbon biodisk also has a good shock load tolerance. In the process of wastewater treatment, active carbon has adsorptive action only during the first 7 d of biofilm-forming, the main effect is biodegradation after biofilm has been formed.
