摘要
对以H2O2为氧化剂,FeSO4.7H2O为催化剂的Fenton氧化法处理高浓度复杂焦化废水进行了系统研究,氧化处理后用氯化铁作为混凝剂,对COD、NH3-N、色度及浊度的去除率进行了考查。确定了氧化试验的影响因素和最佳混凝试验条件。结果表明:当pH值控制在3左右,反应时间为30 min,反应温度为80℃时,焦化废水COD,NH3-N,浊度和色度去除率分别达到了93.1%、96.2%、90.8%和90.2%。
Fenton-oxidation-sedimentation was used to treat coking wastewater. The removal of COD, NH3-N, turbidity and color was mainly studied. The infruence effects and conditions were investigated. The results show that the removar efficiency of COD, NH3-N,turbidity and corot can reach 93.1%, 96.2%, 90.8% and 90.2% under the conditions of pH=3. oxidation time 30 min and temperature 80℃ respectivery.
