摘要/Abstract

摘要： 采用Fe(Ⅱ)(EDTA)/O₃工艺处理含聚废水，研究EDTA浓度、Fe²⁺浓度、水力停留时间（HTR）、初始pH对聚丙烯酰胺（PAM）去除率和COD降解效能的影响，探讨了Fe(Ⅱ)络合催化臭氧反应动力学特征及其机理。结果表明：当EDTA浓度为0.050mmol/L、Fe²⁺浓度为0.050mmol/L和HRT为120min时，PAM去除率为75%；增加水样初始pH有利于提高PAM去除率，同时水样pH随HRT增加缓慢下降；废水COD值在HRT为30min内逐渐增至最大，随后逐渐减小并达到稳定。Fe(II)(EDTA)/O₃工艺处理含聚废水的反应符合二级动力学反应，初始PAM质量浓度在50~100mg/L范围内，二级反应速率常数为2.35×10^-4~3.35×10^-4L/(mg·min)。

Abstract: The Fe(II)(EDTA)/O₃process was used to degrade polymer-contained wastewater. The effects of influencing factors such as EDTA concentration,Fe²⁺ concentration,hydraulic retention time (HRT) and initial pH on removal rate of polyacrylamide (PAM) and degradation efficiency of COD were studied. Moreover,the kinetic characteristics and mechanism of Fe (Ⅱ) complexing and catalysis reaction of ozone were discussed. Results showed that the PAM removal rate reached at 75% when the EDTA concentration was 0.050mmol/L,Fe²⁺ concentration was 0.050mmol/L and HRT was 120min. The increase of initial pH was in favor of PAM removal rate. At the same time,the pH of the wastewater decreased slowly along with the HRT. In addition,the COD values of the wastewater gradually increased to maximum when the HRT was during 30min and then decreased with the time gradually to a stable value. Furthermore,the degradation of polymer-contained wastewater conformed to the second-order kinetics whose rate constant was 2.35×10^-4—3.35×10^-4L/(mg·min) when the initial PAM concentration was 50—100mg/L.
