PHOTO-CATALYSIS DEGRADATION OF MICROPOLLUTANTS IN AQUATIC SYSTEMS

摘要: 以珠江官洲河段的水样为研究对象，采用Fenton法和UV-Fenton法对水样中有机微污染的降解效果进行研究.研究表明，在室温条件下，Fenton法和UV-Fenton法对微污染水样均具有较好的降解能力，60min内TOC降解效率分别超过40％和80％，研究确定了Fenton试剂H2O2和FeSO4的最佳投加量为10.0mL/L和4.0mL/L，而UV-Fenton最佳照射时间为30min.

Abstract: The study is based on the photocatalysis oxidation in Aquatic Systems. The Fenton and Photo-Fenton were applied in order to degrade the micro-pollutants in Pearl River raw water. The following conclusions were obtained: both Fenton and Photo-Fenton had effect on the degradation of the environmental micro-pollutants.The TOC removal rate of Fenton and Photo-Fenton were over 40% and 80% respectively, and the Photo-Fenton has higher efficiency obviously. The optimal conditions of degradation of the environmental micro-pollutants by Photo-Fenton were found: The optimal dosage of H2O2 and FeSO4 were 90 mmol/L and 0.4mmol/L respectively, and the optimal irradiation time of Photo-Fenton was 30 min.
