More Information
Summary:This invention aims to obtain high concentration ammonium sulfate solution in a process of removing ammonia from an ammonia-containing drainage water by using a gas-liquid separating membrane so as to recover ammonium sulfate solution. The processing device 1 of ammonia-containing drainage water comprises: an ammonia removing device 16 which includes a gas-liquid separating membrane 26, a first liquid chamber 24a provided adjacent to the surface on one side of the gas-liquid separating membrane 26, and a second liquid chamber 24b provided adjacent to the surface on the other side of the gas-liquid separating membrane 26, ammonia-containing drainage water being passed through the first liquid chamber 24a to remove the ammonia, and sulfuric acid solution being passed through the second liquid chamber 24b opposing to the flow of the ammonia-containing drainage water and being in contact with the removed ammonia so as to recover the produced ammonium sulfate solution; an inlet side valve 56 for opening and shutti
