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COD_Mn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 COD_Mn 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^－-N reduction rate were 5.02×10^－4h^－1 and 4.48×10^－4h^{－1 in freshwater and seawater respectively. The reaction rate of the denitrification process in seawater was lower than that in freshwater.}
