The invention belongs to the technical field of garbage treatment, and discloses a composite catalyst as well as a preparation method and application thereof. The composite catalyst comprises polyferric aluminum chloride and green rust, the molecular formula of the green rust is [Fe<2+><1-x>Fe<3+>(OH) ]<x+>[(x/2)(SO <2->)], and x is equal to 0.4-0.5. The composite catalyst provided by the invention comprises the polyferric aluminum chloride and the green rust which have a synergistic effect, so that the composite catalyst has good catalytic degradation activity on carbohydrates, fat, proteins and the like in the kitchen wastes, can effectively treat the kitchen wastes in various complex forms, and is high in degradation efficiency and short in degradation time; and no secondary pollution is generated before and after treatment, and the treatment process is simple and easy to operate. The preparation method of the composite catalyst is simple, raw materials are easy to obtain, and the cost is low. 本发明属于垃圾处理技术领
