中文摘要:
      MOFs作为一种新型催化材料正成为环境领域的研究热点。本论文选取MOFs中MIL-100(Fe)、MIL-100(Fe)@MIP活化过硫酸钠(PS)产生硫酸根自由基(SO4- .)深度处理造纸废水二级生化出水,研究常温下初始pH值、催化剂用量和PS投加量等因素对废水COD去除率的影响,并采用响应曲面法分析多因素对COD氧化降解效果的影响。结果表明MOFs活化PS高级氧化体系深度处理造纸废水最佳的活化条件为:PS:COD=12:1、催化剂用量2 g/L、体系的pH值为6,可以实现32%的COD去除率,响应曲面分析实验表明各影响因素对于降解效果的贡献顺序是:PS投加量>pH值> MIL-100(Fe)用量。
英文摘要:
      MOFs as a new type of catalytic materials, is becoming a research hotspot in the field of the environment. The paper selects MIL-100(Fe),MIL-100(Fe)@MIP of MOFs and Fe2+ activated persulfate (PS) for the oxidation of the wastewater after secondary treatment was studied through batch experiments.The effect of initial pH, catalyst dosage and PS dosage on the degradation efficiency of wastewater were examined, also multiple factors in removing COD from the effluent were evaluated using response surface methodology. The highest COD removal rate was 32%, obtaining under the optimum activation condition of the PS: COD=12:1 and 2g/L catalyst dosage at pH=6. The response surface methodology experiments showed that the order in COD removal efficiency was PS dosage >pH >MIL-100(Fe) dosage.
