Combined treatment system for cyanogen-containing waste liquid and waste gas

The utility model discloses a combined treatment system for cyanogen-containing waste liquid and waste gas. The combined treatment system comprises a waste liquid treatment tank and a waste gas absorption tank; the waste liquid treatment tank is used for containing cyanogen-containing waste liquid; the waste gas absorption tank is used for containing waste gas absorption liquid; the waste liquid treatment tank is communicated with the waste gas absorption tank through a pipeline; one end of the pipeline extends into the bottom of the waste gas absorption tank; and the tank cover of the waste liquid treatment tank is connected with a ventilation pipeline for introducing compressed air. According to the combined treatment system for the cyanogen-containing waste liquid and the waste gas, the cyanogen-containing waste liquid and the waste gas can be subjected to closed and combined reaction treatment, so that the toxic waste liquid and the waste gas meet the national emission standard after being treated; the hu
