摘　　要：为筛选出有效、安全、经济的杀灭红虫药剂,以保证居民饮用水安全,研究了氯胺、二氧化氯、次氯酸钠和过氧化氢,在20℃、无光照条件下对该种红虫单一和联合的杀灭效果。结果表明,所用消毒剂在一定剂量下(次氯酸钠4.0mg/L、氯胺>4.0mg/L、二氧化氯8.0mg/L和过氧化氢0.01%)都能在短时间内(2h)取得较好的杀灭效果。次氯酸钠、二氧化氯和过氧化氢之间对红虫的杀灭存在拮抗作用。从保证居民饮用水质量和实际的可操作性角度出发,认为二氧化氯是一种较理想的杀虫药剂。Disinfectants such as chloramines, chlorine dioxide, sodium hypochlorite and hydrogen peroxide were used respectively for annihilate Chironomus larva in drinking water treatment. Additionally, two of those disinfectants in different dosages were applied together to test the synergetic efficacy but antagonism existed between any two of sodium hypochlorite, chlorine dioxide and hydrogen peroxide. It is concluded that in view of effectiveness, safety and easiness of operation, chlorine dioxide is the best one of the disinfectants.
