【摘要】 通过自制的光催化剂对某厂焦化废水进行了处理。通过实验,论述了光催化剂的制取过程,并对其处理性能进行了评价,在低成本下,取得了比较好的效果。实验表明,通过混凝沉降预处理后,在紫外光照射下,加入适量H2O2,能够大大提升光催化剂的处理效率,通过40-60 min反应,可使COD去除率达到94%以上,基本达到相关的排放标准。更多还原

【Abstract】 This paper discusses the treatment for coking wastewater of one plant with selfmade photo catalyst.In the experiment,the making process of the photo catalyst is described,the treatment performance is evaluated and satisfactory results can be got with low cost.Experiments show that,through flocculation pretreatment and under UV illumination,the treatment efficiency of photo catalyst can be greatly enhanced when adding suitable H2O2;40-60 mins of reaction can make COD removal rate reach above 94%,meeting the requirements of the related emission standards.更多还原
