A system and method for reducing sulfur dioxide-containing gas by a binary method. The system for reducing sulfur dioxide-containing gas by a binary method includes a gasifier, which is used for performing a gasification reaction of a carbon-based solid fuel and a gasifying agent, and is used for reducing SO2 in the sulfur dioxide-containing gas by a binary method using the coal gas and semicoke generated by the gasification reaction. The present invention innovatively uses the gasifier as a reduction reactor for sulfur dioxide-containing gas, and uses the two binary products, namely semicoke and coal gas, generated by gasifying the carbon-based fuel in the gasifier to perform binary reduction of SO2 in the sulfur dioxide-containing gas, strengthening the reduction effect and improving the SO2 conversion rate.
