Background
As cyanide is a very toxic substance, the very small amount of cyanide can kill people and livestock in a short time, the allowable discharge concentration is 0.5mg/L, and once the cyanide enters water or soil, the harm of aquatic organism poisoning, crop yield reduction and the like can be caused. The high-concentration cyanide-containing waste liquid can not be treated by a biochemical method, and the high-concentration cyanide can be treated by high-temperature incineration or heating hydrolysis, but the high-concentration cyanide-containing waste liquid consumes a large amount of energy, and has the disadvantages of many supporting facilities, complex operation and high operation cost; in addition, the treatment can be carried out by adopting a chlorine oxidation mode, but the chlorine needs to be hydrolyzed in water and has poor oxidation capability, so that the treatment time is long for the high-concentration cyanogen-containing waste liquid, the consumption of the chlorine is high, and the reaction effect is very easily influenced by the pH value and the ammonia nitrogen concentration in the water. Therefore, the cyanide is thoroughly decomposed and removed by selecting a proper treatment technology, and the method has important practical significance.

The method has the advantages of thorough cyanogen breaking, small occupied area and small sludge amount, and CN-can be reduced to be below 0.1 mg/L. The method has the disadvantages that cyanide is very easily entrained in nitrogen and hydrogen discharged in the electrolytic process, the cyanide entrained in the gas is usually treated by a spray mode by using an absorption tower, but the gas with the cyanide is less obstructed in the absorption tower, so that the retention time of the gas with the cyanide in the absorption tower is short, and the treatment effect of the cyanide is influenced.
