光合细菌净化有机废水的实验研究

Organic Wastewater Treatment by Photosynthetic Bacteria

目的:光合细菌(PSB)能降解多种有机污染物,其处理有机污水不带来二次污染且经济、简便。方法:Rhodopseudomonas palustris No.7在厌氧光照条件下能利用多种类型的有机碳源物质。文章对高浓度有机废水进行了动态处理。结果:接种量35 mL,COD去除率高。结论:本实验成功的实现了COD浓度的降低,为降解多种有机废水提供参考。

Objective: Photosynthetic bacteria(PSB) can degrade many kinds of organic contaminants,the treatment of organic wastewater was no secondary pollution and economy,simple.Method: Rhodopseudomonas palustris No.7 can make use of various types of organic carbon material in the light of anaerobic conditions.the dynamic treatment of high concentration organic wastewater by PSB were studied.Result: After treatment,wastewater's content of COD is decline,35 mL Rhodopseudomonas palustris No.7 obtained higher removal efficiency.Conclusion: Successful implementation of the COD reduction,which can provide reference to degrade many kinds of organic contaminant.
