【摘要】 本文介绍了从豆制品废水流经的底泥中筛选出的PSB“1”号菌株,用它和荚膜红假单胞菌混合后具有高效降解能力;提出了以这两个菌株为主的菌群来处理高浓度有机废水的新工艺;并从光合细菌动力学和基质降解动力学的角度分析了工艺的合理性。试验结果表明,经PSB三级处理后,废水的BOD去除率为97%以上。再经氧化槽处理,水质便达到排放标准。此外,从处理过的水中回收到的菌体富含蛋白质和维生素,这为光合细菌在生态工程中的综合利用开辟了广阔前景。更多还原

【Abstract】 Photosynthetic bacteria strain No.1 was obtained from the sludge sample at asoybean processing factory.The bacteria group composed of the strain and Rhodopseu-domonas capsulata can efficiently treat highly concentrated organic waste water.Thetechnological process of the waste water treatment by the bacteria group is describedand the test results are given.After treatment,the BOD and COD in the waste water aresignificantly reduced.The photosynthetic bacterium can not only be used to treat organic waste water ofhigh concentration but also widely applied in bionomic engineering.更多还原
