Title: Study on Microorganismal Screening of Lake Water Purification
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.
