| 摘 要： | 以硝化细菌和枯草芽孢杆菌为实验菌种,研究其对养殖水体的调控作用。结果表明,实验组养殖污水水质明显优于对照组(P0.05),实验组DO均低于对照组,硝化细菌处理组NH3-N、NO2--N降低率分别为75.41%和92.22%,对COD影响不明显。枯草芽孢杆菌能降低COD,NH3-N、NO2--N的降低率分别为77.82%和87.60%。硝化细菌和枯草芽孢杆菌联合处理组对水质的调控效果优于单菌处理组,NH3-N、NO2--N降低率分别为82.16%和94.62%。

| Abstract: | The controlling effects on aquaculture water qualities were studied by the experimental materials of nitrifying bacteria and Bacillus subtilis. The results show that water qualities of the experimental groups were better than the blank（P＆lt;0.05）. In nitrifying bacteria group, the removal rate of ammonia and nitrite reached 75.41%, 92.22%, respectively, butCOD had no significant change. Bacillus subtilis could removeCOD effectively, with the removal rate up to 77.82%,87.60%, respectively. The united group got the best effect, with the removal rate up to 82.16% and 94.62%, respectively. |
