GAO Xiang1,WANG Guang-hua1,LI Li1,LI Wen-bing1,ZUO Jian-ping2,HE Shui3(1.College of Chemical Engineering and Technology,Wuhan University of Scinece and Technology,Wuhan 430081,China;2.Fuel Gas Factory,Wuhan Steel Corporation Energy Power Company,Wuhan 430083,China;3.Wuhan Steel and Iron Group Coking Company,Wuhan 430083,China)  
This paper makes a compare with "Coal Gas Stripping and Adsorption Process" researched(ZL200610019372.4)and "Traditional Method of Ammonia Stripping with Water Steam" on the aspects of principle,technical process,the treatment effect,economic and environmental benefits of removing ammonia nitrogen.It is found that,comparing with the latter,the equipment of former is more simple;Coal gas as Stripping medium is closed circuit;the cost is lower;the efficiency on removing ammonia nitrogen is higher;NH3-N in the effluent can reach the national discharging standard two without biochemistry processing.It has the efficiency and environmental friendliness.
