Abstract:

以二级出水为处理对象,研究了活性炭(Activated Carbon,AC)吸附,生物活性炭(Biological Activated Carbon,BAC)过滤,臭氧(Ozone,O3)氧化对超滤膜污染的缓解作用及其对水中有机物的去除效果。具体考察了AC投加量和吸附时间,BAC的空床停留时间(Empty Bed Contact Time,EBCT),以及臭氧投加量等因素产生的影响。结果表明,这三种预处理方式可有效去除有机物,使水中DOC与UV254值明显降低。AC投加量由0.5 g/L增加至5 g/L,吸附时间由5min延长至8h,膜污染未得到缓解。BAC预处理随EBCT由30min延长至6...
