mesocyclops leukarti of zooplankton propagates excessively in eutrophic water body and it cannot be effectively inactivated by the conventional drinking water treatment process. In order to tackle this problem, a study of removal effect on Mesocylops leukarti with chlorine dioxide in a waterworks was performed. The results showed that mesocyclops leukarti could be effectively removed from water by 1.0 mg/L chlorine dioxide prcoxidation combined with the conventional drinking water treatment process. Higher oxidizability and molecular state of chlorine dioxide in water is the key to the inactivation of mesocyclops leukarti. The chlorite, disinfection by-products （DBPs） of chlorine dioxide, was stable at 0.45 mg/L, which is lower than that critical value of the USEPA. GC-MS examination showed that the quantity of organic substance in the water treated by chlorine dioxide obviously decreased. Ames test further revealed that the mutagenicity was reduced by chlorine dioxide with respect to prechlorine. The propagation ofmesocyclops leukorti can be inactivated effectively and safely by chlorine dioxide pre-oxidation.

mesocyclops leukarti of zooplankton propagates excessively in eutrophic water body and it can not be effectively inactivated by the conventional process in drinking waterworks for its special surface structure. In this paper, a study of removal efficiency on mesocyclops leukarti with chlorine dioxide in a drinking waterworks was performed. Bench scale results showed that chlorine dioxide is more effective against mesocyclops leukarti. And mesocyclops leukarti could be effectively removed from water by 1.0 mg/L chlorine dioxide preoxidation cooperated with the conventional process during the full scale study. The chlorite, *** of prechiorine dioxide, was constant at 0.45 mg/L after filtration, which was lower than the critical value of the USEPA. GC-MS examination and Ames test showed that the quantity of organics and the mutngenicity in the water treated by chlorine dioxide is obviously less than that of prechlorination.

Study of removal effect on mesocyclops leukarti with oxidants

Cyclops of zooplankton propagates prolifically in eutrophic waterbody and it cannot be exterminated by conventional disinfection process. The mutagenicity of mesocyclops leukarti and its extermination with oxidants in a drinking waterworks in China were studied. Among five oxidants for use in bench-scale, chlorine dioxide is the most effective and the potassium per-manganate is the weakest against mesocyclops leukarti under the same conditions. Full-scale results showed that mesocyclops leukarti could be effectively removed from water by 1.0 mg/L chlorine dioxide preoxidation combined with conventional removal physical process. After filtration, chlorite, a by-product of prechlorine dioxide, is stable at 0.45 mg/L, which is lower than the critical value of the USEPA. GC-MS examination and Ames test further showed that the quantity of organic substance and the mutagenicity in water treated by chlorine dioxide preoxidation are obviously less than those of prechlorination.

本研究在室内评价了在济宁采集的捕食性刘氏中剑水蚤单用及与球形芽孢杆菌(B.s.)或苏云金杆菌以色列变种(B.t.i.)合用对蚊幼虫的控制效果。在室内,刘氏中剑水蚤对白蚊伊蚊Ⅰ龄幼虫的捕食效果好于对中华按蚊和淡色库蚊幼虫的效果。蚊笼模拟试验表明,刘氏中剑水蚤可分别于9、10和7周内消灭淡色库蚊、中华按蚊和白蚊伊蚊的幼虫种群。该剑水蚤增长速率快,大量培养经济易行。现场试验证明,刘氏中剑水蚤虽可在蚊虫孳生地存活时间长于蚊虫季节,但单用该剑水蚤不能象化学杀虫剂一样快速完全地控制三种蚊虫。刘氏中剑水蚤与B.s.或B.t.i.合用,应用刘氏中剑水蚤的长持效和生物杀虫剂的速效,取得了高效、持久的防治效果。因此二者合用可用于蚊虫防治并可作为蚊虫综合防治的一个组成部分。
