| titleOfInvention | Method for treating ammonia desulfurization waste liquid by oxidation method |
| abstract | The invention provides a method for treating ammonia desulfurization waste liquid by an oxidation method, and belongs to the technical field of desulfurization waste liquid treatment. According to the method, oxidation reaction is conducted by blowing air or oxygen into the ammonia desulfurization waste liquid; ammonium thiosulfate in the desulfurization waste liquid is oxidized into ammonium sulfate in the oxidation reaction process; ammonium thiocyanate is not oxidized, but continues to be reserved in the desulfurization waste liquid; and then ammonium thiocyanate is extracted through evaporation and secondary crystallization. The method is suitable for treating desulfurization waste liquid generated in a gas desulfurization and decyanation technological process by a catalytic oxidation method, and suitable for waste liquid treatment in the desulfurization technology field of hydrogen sulfide such as coke oven gas, natural gas, coalbed methane and refinery gas. With the adoption of the method, ammonium thiosulfate salt in the waste liquid can be converted to ammonium sulfate salt, ammonium thiocyanate salt can be protected, and ammonium sulfate salt and ammonium thiocyanate salt can be separated and purified from the waste liquid into a product. |
