活性炭催化剂对臭氧氧化污水深度处理中nbsCOD的研究

Study on the Removal Efficiency of Ozonation with Activated Carbon Catalysts on nbsCOD in the Advanced Sewage Treatment

研究以活性炭(AC)为基材的催化剂对臭氧氧化可溶性难降解有机物(nbs COD)的去除效果。以可溶性行难降解有机物苯胺(C_6H_5NH_2)、苯酚(C_6H_5OH)为研究对象,通过试验研究得到:反应60 min时,催化臭氧氧化对C_6H_5NH_2、C_6H_5OH和污水厂滤后水的COD去除率均可达到80%以上,效果显著,比单独臭氧氧化效率提高50%以上,且具有普遍适用性。

Analyzing the removal efficiency of Ozonation with activated carboncatalystson nbsCOD in Sewage Treatment. Using soluble and refractory organics, aniline and phenol, as the study object to do the tests. According to the results, when the reaction time is 60min, the removal rate of the Ozonation treatment with catalysts on aniline and phenol, and on COD in the filtered water from the sewage treatment plant can he up to above 80 %, which shows a remarkable effect. Compared with using the Ozonation treatment only, Ozonation treatment with catalysts improves the ozonation rate up to above 50 %, and is of more general applicability.
