Modified graphene oxide immobilized microbial composite material as well as preparation method and application thereof

The invention discloses a modified graphene oxide immobilized microbial composite material as well as a preparation method and application thereof, and belongs to the technical field of sewage treatment. Graphene oxide is subjected to specific chemical modification treatment to be modified into a material with good biocompatibility, and the modified graphene oxide is adopted to fix functional microorganisms to overcome activity inhibition of the functional microorganisms, so that the biomass of nitrogen and phosphorus removal bacteria in a treatment reactor is greatly improved, and the nitrogen and phosphorus removal effect is improved. The efficient and synchronous nitrogen and phosphorus removal treatment on the landfill leachate is realized. 本发明公开了一种改性氧化石墨烯固定化微生物复合材料及其制备方法与应用，属于污水处理技术领域。本发明通过对氧化石墨烯进行特定的化学改性处理，将其修饰为具有良好生物相容性的材料，并且采用改性氧化石墨烯固定功能微生物，克服其对功能微生物的活性抑制，从而大幅提高处理反应器内脱氮除磷菌的生物量，实现对垃圾渗滤液的高效同步脱氮除磷处理。
