【摘要】：采用Fenton氧化法處理石化含油廢水生化出水,通過正交實驗和單因素實驗優(yōu)化了反應(yīng)工藝條件。正交實驗得到各因素對COD去除率的影響大小順序為:溶液初始pHH_2O_2投加量n(H_2O_2)∶n(Fe~(2+))反應(yīng)溫度。實驗最佳工藝條件為:初始溶液pH 4.0,H_2O_2投加量3.00 mL/L,n(H_2O_2)∶n(Fe~(2+))=10,反應(yīng)溫度35℃,反應(yīng)時間60 min。在此最佳工藝條件下COD可降至60.33 mg/L,COD去除率達(dá)61.33%。在最佳工藝條件下,分別采用超聲(US)-Fenton氧化和紫外光(UV)-Fenton氧化技術(shù)處理含油廢水生化出水,COD去除率分別達(dá)76.77%和80.23%。但單一Fenton氧化、US-Fenton氧化和UV-Fenton氧化工藝對NH_3-N的去除效果均并不明顯。
[Abstract]:The biochemical effluent from petrochemical wastewater was treated by Fenton oxidation process. The reaction conditions were optimized by orthogonal experiment and single factor experiment. The orthogonal experiment shows that the order of influence of each factor on COD removal efficiency is as follows: the initial pH of the solution is: the dosage of nh _ 2O _ 2 / s _ 2 is n _ H _ 2O _ 2 / s _ 2 ~ (2) the temperature of the reaction is as follows: (1) the temperature of the reaction. The optimum technological conditions are as follows: initial solution pH 4.0 ~ H _ 2O _ 2 added 3.00 mL 路L ~ (-1) / L ~ (-1) H _ 2O _ 2 / T _ (2) T _ (2) O ~ (2 +) H _ 2O _ 2, reaction temperature = 35 鈩，
