Abstract

The heterogeneous UV/Fenton process with the appropriate amount of Fe-Mn-Cu-Y as catalyst was developed and various operation conditions for the degradation of phenol were evaluated. The results indicated that by using the heterogeneous UV/Fenton process, the COD(cr) removal rate reached almost 100% for wastewater containing phenol. Compared with the homogeneous process, the developed catalyst could be used at wider pH range in the UV/Fenton process. Comparison of various heterogeneous process showed that heterogeneous UV/Fenton process was best. The heterogeneous UV/Fenton process with Fe-Mn-Cu-Y catalyst is highly efficient in degrading various organic pollutants.

摘要

开发了以适量的铁-锰-铜-钇为催化剂的非均相紫外/芬顿工艺，并评估了苯酚降解的各种操作条件。结果表明，采用非均相紫外/芬顿工艺，含酚废水的化学需氧量（铬）去除率几乎达到100%。与均相工艺相比，所开发的催化剂在紫外/芬顿工艺中可在更宽的pH范围内使用。各种非均相工艺的比较表明，非均相紫外/芬顿工艺效果最佳。以铁-锰-铜-钇为催化剂的非均相紫外/芬顿工艺在降解各种有机污染物方面具有很高的效率。
