摘要
以含有苯系物的废水为研究对象,在启动和运行SBR反应器的基础上,加入复合菌剂M4,比较生物强化前后及持续运行期间SBR去除COD、苯、甲苯、乙苯的效能.结果表明:生物强化后,COD、苯、甲苯和乙苯的降解率分别提高了17.5%,16.5%,15.1%和19%;持续运行期间,COD去除率提高了0.8%,苯,甲苯和乙苯的平均去除率下降了4.7%,2.6%和1.8%,说明M4有着较好的稳定性及可持续性,该研究为M4生物菌剂的开发及生物强化技术的工程应用奠定基础.
The waste water containing benzene series was studied,on the basis of starting and running SBR reactor,the efficiency of the removal of COD,benzene,toluene and ethyl benzene in SBR was compared by adding the compound bacterium M4.The results show that：the degradation rate of COD,benzene,toluene and ethyl benzene increased by 17.5%,16.5%and 15.1%and 19%respectively,and the removal rate of COD increased by 0.8%,the average removal rate of benzene,toluene and ethyl benzene decreased by 4.7%,2.6% and 1.8% during the continuous operation.And the results show that M4 has good stability and sustainability,which lays a foundation for the development of M4 and the engineering application of bio-strengthening technology.
