微电解-Fenton氧化法去除垃圾渗滤液中有机物
Removal of organic pollutants in landfill leachate by microelectrolysis-Fenton process
摘要
Abstract
Iron-carbon microelectrolysis and its Fenton process were used to treat landfill leachate. The factors, such as pH, reagent dosage, reagent ratio, and reaction time were investigated. The landfill leachate COD decreased to 5 960 mg/L and COD removal reached 51.8% after iron-carbon microelectrolysis under the optimal conditions of initial pH value of 3, iron to carbon mass ratio of 4, iron-carbon dosage of 0. 6 g/L, and reaction time of 60 min. The optimal operating conditions of iron-carbon microelec-trolysis-Fenton process were H2O2 dosage of 11 mL/L and the reaction time of 100 min after iron-carbon microelectrolysis. The landfill leachate COD after iron-carbon microelectrolysis-Fenton process decreased to 4 480 mg/L and COD removal reached 63. 8%. Humic matters of large molecule were removed and decomposed into small molecular compounds after iron-carbon microelectrolysis and its Fenton process. Fenton process had stronger destruction performance for humic matters than iron-carbon microelectrolysis.关键词
