| 摘 要： | 采用动态膜生物反应器(DMBR)处理养殖废水,考察盐度为0～3 000mg·L-1时动态膜生物反应器的脱氮效能.结果表明:DMBR对养殖废水的CODMn和NH3-N的去除效果保持稳定,分别为93%,87%左右;在盐度提高到1 000mg·L-1后,DMBR内反硝化速率明显提高,对NO3-N的去除率提高到97%,总氮去除率也达到94%.在盐度为0～3 000mg·L-1下,DMBR处理养殖废水的出水水质达到SC/T 9101-2007《淡水池塘养殖水排放要求》中的一级排放标准.

| Abstract: | CODMn and nitrogen removal efficiency from salt-bearing aquaculture wastewater were investigated at different salinity varying from 0 to 3 000 mg·L-1 using dynamic membrane bioreactor(DMBR).The experimental results show that the removal rates of CODMn and NH3-N in DMBR kept stable,which are 91% and 87% respectively.When salinity is 1 000 mg·L-1,the denitrification rate is improved obviously,the removal rate of NO-3-N increases to 97% and total nitrogen removal rate reaches 94%.The effluent quality meet the first grade discharge standard of requirement for water discharge from freshwater aquaculture pond(SC/T 9101-2007). |
