In order to solve the problem of low storage safety limit of conventional hazardous waste storage methods, the application research of industrial modular technology in hazardous waste temporary storage warehouse was proposed. According to the source and generation principle of hazardous waste, the production and emission characteristics of hazardous waste were analyzed, the production and emission coefficients of pollutants in hazardous waste were obtained by calculating the output coefficients of pollutants in hazardous waste, the storage index system of hazardous waste was established combined with the structural level of temporary storage warehouse of hazardous waste, the comprehensive weight of each index was obtained, and the functional modules of temporary storage warehouse were decomposed. The storage module unit and skid unit of hazardous waste temporary storage warehouse were designed by using modular technology, and the method was applied to the design of a hazardous waste temporary storage warehouse. The results show that this method can effectively improve the storage safety limit of hazardous waste.
