▎ 摘　　要

NOVELTY - Preparing carbon source for wastewater treatment by using kitchen waste comprises food waste undergoes a phase change and degrading into a phase change liquid by the aerobic fermentation of the microbial compound bacterial agent, and obtaining the carbon source for wastewater treatment, The microbial composite bacterial agent comprises microbial bacterial agent, and said microbial bacterial agent comprises aerobic bacteria, and auxiliary material. The auxiliary material comprises iron-based Metal-organic frameworks (MOF) nanocomposite material. The iron-based MOF nanocomposite material is prepared by first obtaining iron-MOF-graphene oxide(GO) from iron-based metal-organic framework and graphene oxide through a one-step solvothermal synthesis method, and then mixing it with n-butyl triamine thiophosphate through high-temperature treatment. USE - The method is useful for preparing carbon source for wastewater treatment by using kitchen waste, which is useful in improving the efficiency of sewage treatment in sewage plants, in the preparation of microbial composite bacterial agents for the degradation of kitchen waste, and wastewater treatment, and used as high quality carbon source of microorganism in sewage treatment. ADVANTAGE - The method enables to prepare carbon source for waste water treatment by using kitchen waste, which has better biodegradability, and enhances the wastewater treatment effect, denitrification and dephosphorization effect of sewage treatment, and promotes the growth of microorganism in the active sludge, improves the processing efficiency of the waste water, and provides theoretical basis and basis for realizing kitchen waste resource utilization. The carbon source exhibits complex water quality component, organic matter rich content and containing ammonia nitrogen and so on inorganic salt, the degradation process substantially does not include the path for generating biogas, ammonia oxidation reaction and denitrogen process nitrogen consumption is more complete, the carbon content of the carbon source is higher. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for carbon source prepared by the method of utilizing kitchen waste to prepare a carbon source for wastewater treatment useful in improving the efficiency of sewage treatment in sewage plants
