Abstract:
A quantifiable assessment system and method were developed to clarify the technical characteristics and advantages of chlorine/UV process. Based on the pilot test platform of a water supply plant in Mudanjiang area of Songhua River basin, 12 schemes were obtained through different combinations of chlorine to nitrogen ratio and UV dose in the chlorine/UV process. A comprehensive performance assessment model of the chlorine/UV process was constructed by the improved analytic hierarchy process (AHP), and the quantitative assessment was carried out to obtain the optimal operating parameter ranges of the process aiming at controlling ammonia nitrogen. The optimal parameters were as follows: the ratio of chlorine to nitrogen was 5-6, and the UV dose was 33.5-48.0 mJ/cm2.
