摘要
以TiO2为催化剂,H2O2为氧化剂,在紫外光照射下采用多相光催化氧化法对焦化废水进行处理,对COD去除率的各种影响因素进行了研究探讨,从而得出其较佳工艺条件.结果表明该法可使焦化厂二沉池废水COD从348.3mg/L降至52.1mg/L,COD的去除率可达85.0%以上.
In this text TiO_2 as the catalyst,and H_2O_2 the oxidant,the heterogeneous mere catalysis is adopted to oxidize the law to deal with the coking waste water under the circumstances that the ultraviolet ray shines.Inorder to obtain its best process conditions, a research was conducted on various factors influencing removal efficiency of COD.The result indicates this law can make Coking and Chemistry Plant two sink pool waste water COD drop,from 348.3mg/L to 52.1mg/L and the removal rate up to 85.0%.
