摘    要:研究了臭氧催化氧化与生物活性炭联用技术对氯化消毒副产物(DBPs)的控制效能。结果表明:常规工艺出水中分子质量为2000u左右的疏水性有机物是氯化消毒副产物的主要前质,其占DOC与UV254的比例分别为70%和80%,并与UV254有良好的线性相关性,故可用UV254作为DBPs前质的替代指标。臭氧催化氧化与生物活性炭联用对DBPs前质的去除效果显著,其中臭氧催化氧化可有效去除三卤甲烷(THMs)前质中的疏水性有机物及部分亲水性有机物,并提高了DBPs前质的可生化性,是给水深度处理中控制THMs前质的主要工艺环节。臭氧催化氧化/生物活性炭对UV254的控制是减少DBPs生成的一条有效途径。

关 键 词:臭氧催化氧化  生物活性炭  疏水性有机物  亲水性有机物

Abstract:An investigation of the combined process of catalytic ozonation and biological activated carbon for the removal of DBPs precursors was conducted. The results show that hydrophobic organic compounds with molecular weight of 2 000 u are the most reactive precursors of DBPs which account for 70% and 80% of DOC and UV254 respectively in the effluent of the conventional treatment process. There is a perfect linear correlation between UV254 and THMs and HAAs potentials. UV254 is an ideal surrogate parameter for determining DBPFP in the advanced treatment process. Catalytic ozonation combined with biological activated carbon process has absolute advantage in DBPFP removal. Catalytic ozonation process is the primary part in removing the precursors of THMs, which not only removes hydrophobic and hydrophilic organic compounds further, but also enhances the biodegradability of the precursors of DBPs. It is demonstrated that by controlling UV254, catalytic ozonation combined with the biological activated carbon process is a feasible way to control DBPs formation.
Keywords:HAAFP  THMFP  UV254
