采用一体式光催化氧化与生物降解反应器,在波长为254 nm的紫外辐射条件下进行生物降解苯酚与2,4,6-三氯酚(2,4,6-TCP)混合液.分别比较了分步耦合与同步耦合对苯酚降解速率的影响,同时还比较了间歇和连续条件下苯酚与2,4,6-TCP混合液在单独光催化、单独生物降解以及光催化与生物降解共同作用下的降解规律.实验结果表明:采用光/生物联合方法对混合溶液进行降解时,混合溶液中苯酚和2,4,6-TCP的降解速率为最快,相应COD的平均去除率也最高.
Integrated photocatalytic and biological reactor was used for biodegradation of phenol and 2,4,6-trichlorophenol(TCP) under UV illumination with 254 nm of wavelength together with biofilm.Intimately coupled photocatalysis and biodegradation(P&B) was compared with sequential coupled photocatalysis and biodegradation to investigate phenol and TCP removal rate.The phenol and TCP removal regularities,respectively by photocatalysis alone(P),biodegradation alone(B) and intimately coupled photocatalysis and biodeg...
