The invention provides a carbon disulfide removal method based on a low-temperature plasma reactor and a coupling catalyst. The carbon disulfide removal method comprises the steps of modified powder preparation, modified powder spraying, coupling catalyst preparation and low-temperature plasma treatment. According to the invention, by adopting the carbon disulfide removal method to treat waste gas, the carbon disulfide removal rate can reach 99.5-99.8%, the energy efficiency is high, and the energy efficiency of the method is improved by 6-11 times compared with an existing low-temperature plasma carbon disulfide removal method; the catalyst has no attenuation on the carbon disulfide removal effect within 200-350 h, and is lasting in catalytic effect and stable in catalytic performance; the dosage of the catalyst required for treating unit volume of waste gas is reduced by 9-14%; carbon disulfide waste gas can be completely decomposed into CO2, H2O, N2 and other pollution-free substances, so that up-to-standa
