生化后的丙烯酸及酯废水COD为550 mg/L，需进行深度处理才能达标排放。研究了活性炭强化的臭氧氧化工艺对该废水的处理效能，考察了废水碱度、活性炭装填高度、臭氧浓度和废水柱外循环流量对COD去除率的影响。实验结果表明，在最佳条件下反应2 h，废水COD可降至35 mg/L，达到《污水综合排放标准》（GB 8978—1996）中的一级标准要求。

The COD of bio-chemically treated acrylic acid and ester wastewater is 550 mg/L. It is necessary for the wastewater to have advanced treatment,so as to reach the discharge standard. The treatment efficiency of activated carbon enhanced ozone oxidation process used for the wastewater has been studied. The effects of wastewater alka-linity,activated carbon filling height,concentration of ozone and wastewater extra column circulating flow rate on the COD removing rate are investigated. The experimental results show that,under optimal condition,the reaction goes on for two hours,the wastewater COD can be reduced to 35 mg/L,meeting the first class requirements of the Inte-grated Wastewater Discharge Standard(GB 8978—1996).
