摘要:
采用静态实验,考察微电解-Fenton法预处理制革废水中各种工艺参数对处理效果的影响.确定最优条件:微电解进水pH值为3,反应时间为1 h,Fe和C的体积比为1∶1,铁屑的投加量为200 g; Fenton反应的H2O2的投加量为3 mL,反应时间为50 min.在此条件下,制革废水经微电解-Fenton法预处理,化学需氧量去除率能达到80%左右,出水水质得到较大改善,为后继生物处理提供必要的条件.
Abstract:
The effect of various reaction conditions and process parameters on pretreatment efficiency of tannery wastewater by micro-electrolysis and Fenton reagent was investigated,and the optimum operation parameters were obtained by batch experiments.The results indicated that under optimal condition when the reaction time for micro-electrolysis was 1 h,pH value of wastewater was 2,the ratio of Fe to C volume was 1∶1,the dosage of scrap iron was 200 g·L-1,as well as when the dosage of H2O2(30%) for Fenton oxidation process was 3 mL and the reaction time was 50 min,the removal efficiency of CODCr was raised to approximately 80% in raw wastewater.The quality of tannery wastewater has been improved dramatically by the combined technology of micro-electrolysis and Fenton reagent,which makes the wastewater more favorable for biological treatment.
