| 摘 要： | 采用缺氧动态膜生物反应器（Anoxic-DMBR）处理淡水和海水养殖废水。结果表明：缺氧动态膜生物反应器对淡水养殖废水和海水养殖废水的CODMn去除率分别为89.5%和75.5%；出水总氮浓度分别为1.42 mg/L和3.50 mg/L，污泥浓度分别为3850 mg/L和3550 mg/L。由于盐度对反硝化菌的酶产生一定的抑制作用，在海水条件下反硝化效率降低了16%。淡水和海水养殖废水的NO3－-N的降解速率常数分别为5.02×10－4 h－1和4.48×10－4 h－1，海水反硝化过程的反应速率低于淡水条件。

| Abstract: | An anoxic dynamic membrane bioreactor(Anoxic-DMBR) was used to treat aquaculture/mariculture wastewater.The results showed that the CODMn removal rates by A-DMBR for treating aquaculture and mariculture wastewater were 89.5% and 75.5%.The TN concentrations of effluent were about 1.42 mg/L and 3.50 mg/L.And the sludge concentrations were 3850mg/L and 3550 mg/L respectively.Because of the inhibition effect of salt on denitrification enzyme,the denitrification efficiency decreased by 16%.The constants of NO3--... |
