微波诱导氧化连续化处理皂化废水的研究

摘要

Epichlorohydrin saponification wastewater which has many problems, such as high alkalinity and high salinity, is difficult to treat.Saponification wastewater continuous treatment was studied based on the optimal conditions:microwave radiation time was 25 min, radiation power was 850 W, pH was 13, wastewater:activated carbon:slag=20:1:1.The treatment efficiency of NaOH and flocculent was compared.The effective factors, such as height of bed layer, velocity of flow, were studied.%生产环氧氯丙烷产生的皂化废水，碱度高，属于高盐有机废水，处理难度大。本文在已经确定的活性炭／钢渣吸附－微波诱导氧化最佳工艺：废水砄活性炭砄钢渣用量固液比为20砄1砄1，微波辐射功率为850 W，加热温度为100℃，加热时间为25 min， pH值为13。在此基础上对皂化废水进行连续处理，比较了NaOH和凝絮剂处理废水的效果，考查了最佳条件下床层高度和流速对处理效果的影响。
