Summary of Flue Gas Purification and Treatment Technology for Domestic Waste Incineration

Abstract

Incineration technology is widely used in the world as a domestic waste treatment technology. The reason is that the incineration technology can reduce the weight of the treated domestic waste by 80% and the capacity by more than 90%, which is of great significance to the realization of the management goal of domestic waste treatment. However, the problem of flue gas pollution will occur when the waste incineration technology is used to treat the waste. The main harmful substances in the flue gas generated by waste incineration include: smoke, dioxin, SO2, NOx, heavy metal and other pollutants. Therefore, the flue gas can only be discharged into the atmosphere after proper technical treatment and meeting the national emission standards. This paper summarizes the domestic and foreign technologies of waste incineration flue gas purification and treatment, and puts forward suggestions for the development of domestic waste incineration flue gas purification and treatment technology.
