1. A method for preparing a carbon source for wastewater treatment by using kitchen waste, comprising:
adding a complex microbial inoculant into the kitchen waste; and
phase-change degrading the kitchen waste into a phase-change liquid under aerobic fermentation of the complex microbial inoculant; wherein the phase-change liquid is the carbon source for wastewater treatment;
the complex microbial inoculant comprises: a microbial agent comprising aerobic bacteria; and an excipient comprising an Fe-based metal-organic framework (MOF) nanocomposite;
the Fe-based MOF nanocomposite is prepared by the following steps:
mixing an Fe-based metal-organic framework and graphene oxide, performing one-step solvothermal synthesis to obtain Fe-MOF@GO, and then mixing the Fe-MOF @GO with N-(n-butyl) thiophosphoric triamide and performing high-temperature treatment to obtain the Fe-based MOF nanocomposite.
