摘要
高浓度丙烯酸及酯废水成分复杂，毒性高，处理难度较大。利用内循环UASB-好氧接触氧化工艺对高浓度丙烯酸及酯废水进行处理。在进水COD约为10000mg／L的条件下．UASB反应器出水挥发性脂肪酸质量浓度均处于200mg/L以下，pH维持在7．0左右，COD去除率为70％-80％，说明UASB反应器运行良好；好氧接触氧化出水COD达到500mg／L以下，COD去除率达到92％～96％，且运行稳定。
The highly concentrated acrylic acid and ester wastewater is difficult to be treated because it has complex composition and high toxicity. The internal circulating UASB-aerobic-contact oxidation process has been used for treating the wastewater with highly concentrated acrylic acid and ester. The results show that when the influent COD is about 10 000 mg/L, the mass concentrations of the effluent volatile fatty acids from UASB reactor are all lower than 200 mg/L,its pH keeps at around 7.0, and the COD removing rate is 70%-80%. It indicates that the UASB reactor runs well. The final effluent COD of aerobic-contact oxidation is lower than 500 mg/L. The removing rate of COD can reach 92% to 96%, and runs stably.
