介绍了一种强碱性高浓度含砷有机废水的处置工艺.废水经“絮凝、氧化沉砷、微电解+芬顿、三氯化铁除砷”等组合工艺处置后,出水:COD＜1 000 mg/L,As＜0.5 mg/L,pH≈6～9,符合《污水综合排放标准》(GB8978-2002)标准要求.“,”The paper will make a research of disposition technology of strongly alkaline organic wastewater with a high concentration of As.In order to dispose the wastewater,we use flocculation and Oxidization to sink As with micro electrolysis + Fenton and FeCl3 to remove As.After these technologies,we think the quality of yielding water will meet the standards of《 Integrated Wastewater Discharge Standard》,COD ＜ 1 000 mg/L、As ＜0.5 mg/L,pH≈6 ～9.
