- 摘要:
- 利用对湖水净化能力较强的枯草芽孢杆菌、贫营养菌、硝化细菌、乳酸菌、光合细菌，采用L1873正交实验设计优化复合菌剂配比，对湖水净化微生物进行了筛选研究。结果表明：各菌的最佳配比为枯草芽孢杆菌8 g/L；光合细菌6 g/L；乳酸菌0.4 g/L；硝化细菌10.2 g/L；硝化细菌20.6 g/L；贫营养菌0.2 g/L，此配比条件下，湖水经30 d净化，总磷含量降低85.71%，总氮含量降低75.69%，COD值降低74.68%，表明该比例复合菌剂能够有效的降低湖水中的总磷、总氮、COD值，对湖水净化效果良好。
- Abstract:
- Taking Bacillus subtilis，Oligotrophic Bacteria，Nitrifying bacteria，Lactic acid bacteria and Photosynthetic bacteria which had higher purification ability as materials，the screening of purification microorganisms in lake water were studied，and the optimum proportion of the composite bacterial strains through orthogonal experiment.The results showed that 8 g/L Bacillus subtilis，6 g/L Photosynthetic bacteria，0.4 g/L Lactic acid bacteria，0.2 g/L Nitrifying bacteria No.1，0.6 g/L Nitrifying bacteria ?No.2,0.2 g/L Oligotrophic Bacteria was the best proportioning.Under these conditions，the results of lake water purification showed that total phosphorus，total nitrogen and COD decreased 85.71%，75.69% and 74.68% in 30 days，respectively.The composite bacterial strains could purify water obviously.
