摘要:
采用缺氧-动态膜生物反应器处理海水养殖废水,研究不同水力停留时间(HRT)下,其化学需氧量(CODMn)降解和反硝化过程.结果表明:当HRT为4 h,总氮(TN)的去除率为72%,CODMn的去除率为71%;当延长HRT到8 h,TN和CODMn去除率略有增加;当HRT大于10 h,CODMn的去除率保持稳定在87%;随着HRT的延长,减缓了膜污染的进程,当HRT达到10 h以上,膜反冲洗周期稳定在9 d.当HRT大于10 h,所处理的出水水质能够达到国家标准SC/T 9103-2007《海水养殖水排放要求》的二级排放标准.
Abstract:
An anoxic dynamic membrane bioreactor(anoxic-DMBR)was used to treat mariculture wastewater. The chemical oxygen demand chemical oxygen demand(CODMn )degradation and denitrifying process of anoxic-DMBR at different hydraulic retention time(HRT)were studied. The results showed that the removal rate of total nitrogen(TN)and CODMn were 72% and 71% respectively when the HRT was 4 h. The removal rate of TN and CODMn increased slightly with the increasing of HRT to 8 h. When the HRT was greater than 10 h, the removal rate of CODMn kept stable at 87%. An increase of HRT would reduce the phenomena of membrane fouling. When the HRT was greater than 10 h, the backwashing cycle kept stable at 9 d and the effluent quality of A-DMBR reached the second grade discharge standard of Requirement for Water Drainage Standard for Sea Water Mariculture(SC/T9103-2007).
