Abstract: The governance process of urban and rural garbage in China in the past 40 years was summarized， and the development status of garbage treatment technology in the past 20 years at home and abroad was combed. The iterative technology of urban and rural garbage treatment in China was actively explored. Meanwhile， the innovative model of using garbage classification complex to solve urban and rural garbage in China was put forward. Several core technology cases related to garbage mechanical sorting， wet garbage co-fermentation and dry garbage pyrolysis gasification has been successfully researched， which are the concrete implementation and enrichment of the national garbage classification policy and building the environmental protection industry into a strategic new pillar industry. Environmental protection， new energy， organic fertilizer and healthy diet problems can be effectively solved through the implementation of this model.
