摘　　要：采用臭氧催化氧化-曝气生物滤池工艺对印染废水进行深度处理。在室温条件下,试验水样体积为2000 mL,分别使用负载催化剂的陶粒和普通陶粒进行臭氧氧化实验。在通O3时间为15 min,臭氧的投加量达90 mg/L时,废水COD由125 mg/L下降到62 mg/L,去除率达到51%。废水水样中含较多难生物降解的有机物,经过臭氧催化氧化预处理之后,废水的可生化性得到改善。催化陶粒相对于普通陶粒表现出了更加良好的催化效果。采用臭氧催化氧化-曝气生物滤池工艺深度处理印染废水,COD的去除率达到66%,处理效果良好。The catalytic ozonization-biological aerated filter processes were used to treat textile wastewater using ceramsite loaded by catalysts and general ceramsite as catalysts respectively. When the wastewater volume was 2000 mL, the oxidation time was 15 min, the 03 dosage was 90 mg/L, the results showed that the COD of the wastewater was removed from 125 mg/L to 62 mg/L, the removal efficiency of COD was 51%. The biodegradability of the wastewater is improved after ozone catalytic oxidation pretreatment. Compared with the ordinary ceramsite, catalytic ceramsite showed better catalytic effect. COD removal efficiency of catalytic ozonization-biological aerated filter process was more than 66 %.
