| 摘要 |
The present invention relates to a process for removal of ammonium from an ammonium-containing aqueous solution obtained by regenerating an ammonium-loaded ion exchange material with an eluant liquid comprising a chloride-containing salt, said process comprising the step of feeding said ammonium-containing aqueous solution or an ammonia-containing condensate obtained by stripping said ammonium-containing aqueous solution and removing ammonia from the stripping gas by condensation, and a separate aqueous solution of an alkali metal hypochlorite into a reactor for converting the ammonium/ammonia to nitrogen gas and for producing an essentially ammonium-free effluent stream, a portion of said effluent stream from the reactor being returned as the eluant liquid to the regeneration of the ammonium-loaded ion exchange material. |
