| 摘 要： | 随着农村社会经济的发展，农村用水量和废水量日益增加。为有效处理废水，使其稳定达到排放标准，从当地生活垃圾和废水中筛选功能菌株来强化当地的A/O废水处理系统。筛选得到了高效COD去除菌2株和除氮菌2株，将其用于二级A/O废水处理系统。试验结果表明，COD去除率平均增加6.5%，总氮的去除率增加11.6%，氨基氮和硝基氮的去除率增加33.0%和26.8%。

| Abstract: | With development of rural society and economy，rural water consumption and waste water volume are increasing day by day.In order to effectively treat waste water and make it reach discharge standard stably，selection of functional strains from local domestic waste and waste water to strengthen local A/O waste water treatment system were studied.Two highly efficient COD removal bacteria and two nitrogen removal bacteria were screened from local samples and the bacteria were used in secondary A/O wastewater treatment system.Results showed that COD removal rate increased by 6.5% on average，total nitrogen removal rate increased by 11.6%，and amino nitrogen and nitro nitrogen removal rates increased by 33.0% and 26.8%. |
