Title: Treatment of waste water containing ammonia
Inventor: KIYOTAKI KAZUHIRO
IPC: C02F1/58
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To efficiently separate ammonia from waste water containing ammonia. SOLUTION: In the method for separating an ammonia-containing waste water into ammonia gas and water by subjecting ammonia-containing waste water to a stripping process in an atomization tank, ammonia-containing waster water in a raw water tank 1 is pressurized by a high pressure pump 2 and sprayed through a spraying nozzle 3A into the atomization tank 3 under a high pressure of >=100 kg/cm<2> thereby separating into ammonia gas and water. When pH of the ammonia-containing waste-water is excessively low, separation in gaseous phase is impossible because ammonia is ionized, in this case, therefore, it is preferable that an alkaline chemical agent such as caustic soda, calcium hydroxide is added so as to adjust the pH to be approx. 11 (about pH 10.5 to 11.5).
