Abstract:Comparative experiments on the inactivation of the first instar larvae of chironomid in distilled water by chlorine and chlorine dioxide were conducted. In addition, inactivation effects of chlorine dioxide on the first instar larvae of chironomid in artificial water and raw water were evaluated. And batch experiments were performed in order to analyze the influence of pH value and temperature on the inactivation efficiency of chironomid larvae with chlorine dioxide. Chlorine dioxide possessed better inactivation effect than chlorine and complete inactivation of chironomid larvae was obtained at dose of 1.5mg/L of chlorine dioxide with 30min disposal. The pH value in range of 5.5~8.1 did not affect the inactivation efficiency of chlorine dioxide. The inactivation efficiency of chironomid larvae decreased as TOC concentration increased. With regard to the temperature, the inactivation efficiency of chironomid larvae was significantly improved with the temperature increasing within the range of 15~30℃. The inactivation rate was reduced to 84.5% when temperature reduced from 30℃ to 15℃.
