Improper disposal of food waste results in pollution of land and water. The efficient treatment of kitchen waste has gradually become a hot topic due to the garbage classification policy. During the process of disposal and transportation of kitchen waste, viscosity is a considerable and necessary factor. It may directly affect the model selection of key equipment and the determination of technological parameters. The study on determination of viscosity of kitchen waste is introduced into physical chemistry experiment as a practical application case. Combining with the engineering practice, the viscosity of kitchen wastes with different composition, different solid content and stirrer speeds were investigated. The results and influencing factors were analyzed. We aim to provide some theoretical basis and suggestion for the model selection of equipment and the parameters of the engineering design of kitchen waste an aerobic digestion. The improved experiment can enhance students’ awareness of applying what they have learned in real application, enhance their understanding of the comprehensiveness and complexity of engineering problems. In this process, inspire the students to think about the most efficient treatment of kitchen waste as a potential resource utilization, cultivate students’ innovate disciplinary literacy based on carbon peak and green environmental protection, and strengthen social responsibility.
