Complex enzyme preparation capable of degrading kitchen waste and preparation method and application thereof

The invention belongs to the technical field of kitchen waste treatment, and particularly relates to a complex enzyme preparation capable of degrading kitchen waste and a preparation method and application thereof. According to the invention, the complex enzyme preparation is obtained by forming a complex enzyme by a lipolytic enzyme, a cellulose hydrolase and a proteolytic enzyme and carrying out embedding treatment on the complex enzyme by using sodium alginate grafted N-(2-aminophenyl)-N-phenylthiourea and polyvinyl alcohol; macromolecular organic matter in the kitchen waste can be quickly degraded; the defect that the water vapor condition is difficult to control in the kitchen waste fermentation process is avoided; no anaerobic bacteria exist and the degradation effect is avoided; the water vapor condition does not need to be adjusted; odor cannot be generated; organic matter in the waste can be rapidly and efficiently degraded at the normal temperature; the treatment effect is good; degradation products
