Discussion of Sewage Sludge Co-incineration based on Dioxin Emission Numerical Simulation Model for Municipal Solid Waste Incineration Process

Co-incineration is one of the best ways to treat sewage sludge (SS) and municipal solid waste (MSW), but it is very important to understand its combustion and gas reaction in the grate to control the emission of pollutants. In this paper, the discussion of SS co-incineration based on the dioxin emission numerical simulation model for the MSW incineration (MSWI) process is proposed. Firstly, the numerical simulation model of DXN emission for the MSWI process is established in ASPEN Plus software by using collected sample data in an MSWI plant in Beijing. Then, the SS and MSW co-incineration numerical simulation model is constructed. Finally, based on SS data in reference, the discussion and analysis are made. These research results provide support for the future research on co-incineration of SS and MSW in Beijing.
