The waste emissions of biomedical laboratories are rising, and affected by the limited capacity of disposal and the management policies, wanton emissions not only pollute the environment, but also cause potential harm. In this paper, the solid waste of biomedical laboratory is used as raw material for gasification and heat treatment of oxygen control, so as to achieve high energy efficiency of waste. The results show that the conversion power of solid waste is related to the type of waste with oxygen concentration. With the increase of oxygen concentration, the specific surface area and total pore volume of solid waste increase. According to the two-stage moving bed solid waste oxygen-controlled heat conversion reaction system, the thermochemical process can be divided into dry section, pyrolysis gasification section and Coke Burnout section, and the overall temperature of the gasification chamber decreases gradually with the change of excess air coefficient.
