%X The experiments of the effect of the ClO2 dosage,initial algal concentration,pH,organic matter and ammonia nitrogen concentration on killing Chlorella in water from reservoir with chlorine dioxide were carried out.The Chlorella removal effect by combining chlorine dioxide oxidation with coagulation was investigated,and the process conditions were optimized.The results showed that the efficiency of killing Chlorella was 71.93% after 10 minutes when chlorine dioxide dosage was 1.1 mg/L.The efficiency of killing Chlorella rose with the increase of chlorine dioxide dosage and initial algal concentration,but decreased remarkably with the increase of organic matter concentration.Ammonia nitrogen had little effect on killing Chlorella.In acidity and basicity conditions,the efficiency of killing Chlorella sharp declined with the increase of pH,but descended slowly from neutral to weak base.For the raw water from reservoir which Chlorella was the advantage alga,the removal efficiency of algae was 98.47% when chlorine dioxide oxidation was combined with coagulation.The best process conditions were that the dosages of ClO2 and aluminium polychlorid were 0.5 mg/L and 5 mg/L,respectively,adding ClO2 and PAC simultaneously.
