采油废水缺氧处理体系细菌和古细菌丰度对比
DOI: 10.3724/SP.J.1145.2009.00519, PP. 519-522
Keywords: 采油废水,古细菌,荧光原位杂交,污水处理
Abstract:
建立缺氧的模拟生物处理体系经过物化预处理的采油废水，利用荧光原位杂交技术(fish)跟踪了废水处理系统启动和稳定过程中真细菌和古细菌相对丰度的变化.结果表明，系统稳定后的cod去除率在40%左右.细菌和古细菌在采油废水生物处理系统中都有很高的比例，并呈现不同的变化趋势.细菌丰度在启动和稳定后维持在15%左右；而古细菌在系统稳定过程中呈现逐渐增加的趋势，比例上升到21%.表明古细菌可以在活性污泥系统中稳定存在并发挥作用，说明古细菌在特定污水处理上具有一定的研究和应用价值.图4表2参14
