摘　　要：针对中小型河流突发性水体污染,以突发氨氮污染为例,探究水体污染应急处理技术。结果表明,氨氮浓度为10 mg/L左右时,平均自然降解系数KN为0.009 d-1;同一工况下,不同工艺对水中氨氮的去除能力表现为活性炭吸附>自然曝气+沸石>自然曝气。但在实际工程操作过程中,综合考虑工程的经济及可行性,在处理突发性氨氮污染时,建议主要采用自然曝气+沸石法去除氨氮,活性炭作为辅助吸附剂,从而提高氨氮的整体去除效果。According to the small and medium-sized rivers of sudden water pollution,water contamination in ammonia nitrogen pollution,for example,to explore the emergency treatment technology. The results showed that the concentration of ammonia nitrogen was about 10 mg / L,average natural degradation coefficient KN= 0. 009 d- 1,the removal of ammonia nitrogen in water capacity under the same condition,respectively was： activated carbon adsorption〉 natural aeration ＋ zeolite〉 natural aeration. But in the actual project operation process,to comprehensively consider the economy and feasibility of engineering,in the event of a sudden the ammonia nitrogen pollution in processing,recommend using natural aeration ＋ zeolite method as main ammonia nitrogen removal method,active carbon as auxiliary adsorbent,thus improve the ammonia nitrogen removal efficiency as a whole.
