Title: Research on Treatment of Micro-polluted Yellow River Raw Water by O_3
Abstract: [Objective] The aim of the study was to seek an efficient treatment process of micro-polluted raw drinking water.[Method] The impacts of pollutant such as chromaticity、CODMn、UV254、NO2-N and NH4+-N under the conditions of different ozone dosages and different ozone adding time was analyzed.[Result] Under this Process,The reductions of CODMn and UV254 were respectively 10% and 58%.And the amount of pollutants such as organic materials was greatly reduced and the drinking water quality was greatly improved.The optimum reaction time was 2 min;the best O3 dose was 2.7 mg/L.[Conclusion] The process of ozone pre-oxidation was found to be efficient in treatment of the micro-polluted source water from the Yellow River.
