一种强碱性高浓度含砷有机废水的处置工艺研究
|
摘要
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,p H≈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 FeCl_3 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.
