Abstract

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+><x>(OH)<2>]<x+>[(x / 2)(SO<4><2->)]<x->, 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.

Description

technical field

[0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a composite catalyst and its preparation method and application. Background technique

[0002] Food waste refers to food residues and food processing waste, non-edible animal and vegetable oils and various oil-water mixtures. The chemical composition of food waste is complex, mainly including water, inorganic salts, organic acids, and various macromolecular organic compounds such as protein, starch, cellulose, heteropolysaccharides, and fat. If the food waste is not handled properly, it may lead to the spread of diseases, and even produce dioxin and other substances to pollute the environment. Therefore, the use of scientific and reasonable methods to deal with kitchen waste can not only prevent environmental pollution and eliminate the threat to the health of residents, but also enable the recycling of valuable organic resources and transform them into usa...
