Abstract: The operation parameter of ozone-granular activated carbon (O3-GAC) process for removing young Chironomid larvae form drinking water was studied. The results indicated that complete inactivation of young Chironomid larvae in filtrated water could be performed under the condition of 1.0mg/L of ozone with 11 min disposal. The removal efficiency of the Chironomid larvae can be further advanced O3-GAC combined process. The Chironomid larvae with low activity could be entirely eliminated in ozone-GAC process with the ozone dosage of 0.7mg/L at the condition of the Empty Bed Contact Time (EBCT) from 11min to 13.5min.

摘要： 研究了臭氧-活性炭工艺去除饮用水中摇蚊幼虫的运行参数。结果表明，臭氧氧化在1.0 mg/L投加量下对滤后水中低龄期摇蚊幼虫可以达到100%的杀灭率，臭氧-活性炭工艺协同作用能够进一步提高去除效果，在空床停留时间（EBCT）11～13.5 min条件下，仅需要0.7 mg/L臭氧投加量能够完全去除经臭氧氧化后活性降低的摇蚊幼虫。
