Fenton试剂氧化—原水调节出水pH法预处理碱性印染废水
Pretreatment of Alkaline Dyeing Wastewater by Fenton Reagent Oxidation-Effluent pH Adjustment with Raw Wastewater
摘要
Abstract
Dyeing wastewater was pretreated by the process of Fenton reagent oxidation-effluent pH adjustment with raw wastewater. The factors affecting the COD removal rate and wastewater pH were studied. Under the optimum conditions of raw wastewater COD 986 mg/L, raw wastewater pH 9.31, Fe2+ dosage 12 mmol/L, n(H2O2) : n(Fe2+)=2, reaction time 30 min and volume ratio of raw wastewater to oxidation effluent 2, the COD removal rate is 26.9% and the effluent pH is 6.60. Compared with normal Fenton oxidation process, the cost for reagent is decreased by 70%.关键词
