Abstract: Taking the 40 t/d kitchen waste collaborative disposal project in a suburb of East China as an example, the collaborative disposal application of kitchen waste and domestic waste incineration was introduced. The kitchen waste was co-processed by domestic waste incineration plant after pre-treatment of “mechanical sorting + crushing and pulping + heating and sand removal + three-phase separation”, which realized the goal of reduction, harmlessness and resource utilization of kitchen waste treatment, overcame a series of problems faced by conventional kitchen waste treatment projects, such as large area occupied, complex process, high investment as well as operation and maintenance costs. The design parameters, operation cost and operation effect were introduced detailed,with the aim of providing reference for small and medium-sized kitchen waste treatment in counties and other areas.

Key words: kitchen waste, domestic waste incineration, pretreatment, odor treatment； collaborative disposal
