Abstract:Hazardous waste causes great damage to the human health and ecological environment, and its harmful components except heavy metals can be fully eliminated by incineration. And the compatibility of hazardous waste is a necessary process to ensure sustainable, stable and economical operation of the incineration system. Based on the multi-objective optimization method and weighted solution algorithm, a compatibility model has been established in consideration of the largest comprehensive disposal capacity and optimal economic benefits. And the compatibility schemes of all target functions under different weights are solved, which not only guarantee the maximum operation capacity of hazardous waste incineration disposal system but also accommodate the largest economic benefits of hazardous waste disposal companies, providing a basis for the companies’compatibility schemes under different production loads and different market environment.
