| titleOfInvention | A method for deep arsenic removal from ammonium sulfate solution based on modified nano-iron |
| abstract | The invention relates to a method for deep arsenic removal from ammonium sulfate solution based on nano-iron, and belongs to the technical field of environmental engineering. The invention overcomes the problems of a large amount of ammonia volatilization, long process flow, long reaction time and high investment cost caused by the iron salt aeration device in the existing method for removing arsenic from ammonium sulfate solution. The arsenic removal rate is over 95%, and the final output of solid ammonium sulfate contains arsenic ≤0.00005%, which meets the requirements of DB53/T 340‑2011 "Smelting sulfur dioxide flue gas to produce ammonium sulfate" as an excellent ammonium sulfate product. At the same time, the invention has a short process flow, The reaction time is short, the adaptability is strong, the operation is simple and convenient, and it is easy to implement in production. |
