(57) [Summary] [Purpose] The river water, which is the raw water for tap water, is often contaminated with ammonia recently. In order to remove ammonia from high-concentration ammonia-containing water such as factory effluent, which is one of the causes of this pollution, the pH has conventionally been adjusted to free ammonia, which is then contacted with air and separated into air before being discharged. However, it is harmful to the human body and causes pollution, so we will improve it. [Structure] The raw waste water is pressurized with a pump, jetted downward from the top of the separation tower, and contacted with an upward air stream to separate ammonia into air, and this ammonia-containing air contains hypobromite ions Ammonia was decomposed or absorbed by contact with a solution or sulfuric acid. |
