摘　　要：以EM菌作为微生物来源,在相同条件下分别采用涤纶、维纶、未处理的炭纤维以及经电化学表面处理的炭纤维作为载体培养生物膜,通过废水中COD、TN、TP各指标的测定比较在不同时期各EM生物膜的除污效果。结果表明,炭纤维作为EM生物膜载体能明显优化除污效果,其中电化学处理后的炭纤维作为载体的EM生物膜系统稳定期对COD、TN、TP的平均去除率能够分别达到97.1%、92.5%、96.0%,相对有机高分子类载体系统提升5%～67%,且对外界环境的变化有很强的适应性。Biofilm carriers and effective microorganisms(EMs)are both important to improve the decontamination performance of biofilms for wastewater.The decontamination performance of biofilms using polyester(PET),polyvinyl alcohol(PVA),carbon fibers(CFs)and electrochemically-treated CFs as biofilm carriers for EMs were investigated by comparing the concentrations of the chemical oxygen demand(COD),total nitrogen(TN)and total phosphorus(TP)of wastewater at different stages of decontamination.The use of all carriers efficiently prevents the loss of mobile EMs.The use of CFs increases the decontamination efficiency.Electrochemically-treated CFs perform best,and the corresponding biofilm has a strong resistivity to the surrounding environment and achieves 97.1,92.5 and 96.0%removal rates for COD,TN and TP,respectively,which are 5%-67%higher than those obtained using PET and PVA as carriers.
