The invention discloses a method for removing SO2 by utilizing soda ash waste liquid and carbide waste slag. CaCl2 in the soda ash waste liquid is utilized to react with the SO2 in flue gas, white CaSO3 settlement is generated, HCl is released and dissolved in water to form hydrochloric acid with very low concentration; Ca(OH)2 in the carbide waste slag is used for neutralizing HCl and generating CaCl2 and water, and CaCl2 is recycled. The desulphurization process mainly consumes Ca(OH)2 in the carbide waste slag. If no local soda ash waste liquid, calcium chloride dehydrate (CaCl2*2HO) produced by the soda ash waste liquid can be purchased for preparing CaCl2 solution. The carbide waste slag can be replaced by lime. The process is characterized by one high, two low and three points of environmental protection. The process firstly has high desulphurization rate, secondly has low fixed-asset investment and low running costs and thirdly utilizes the waste liquid and the waste slag to reduce the environmental pollution. Compared with all prior desulphurization processes, the process has great advantages.
