| 摘 要： | 以水产饲料企业生产废气中的H2S、NH3和三甲胺为处理对象,研究了生物填料塔净化恶臭废气的性能,考察了进气浓度、流量、循环液喷淋密度对恶臭净化率的影响.采用单负荷、双负荷（H2S、NH3）、三负荷3种方式进气,探讨了恶臭组分之间的相互作用.结果表明：对H2S的净化率保持在100%;对NH,的净化率随进气浓度或气体流量的增加而降低,且H2S的存在有利于NH3的去除,而三甲胺的存在则对NH3的净化表现出竞争抑制作用;对三甲胺的净化效果较好,且H,S和NH3的存在对其净化无明显影响.

| Abstract: | By selecting major components of odors(hydrogen sulfide,ammonia and trimethylamine) from feeding factories as targets,the purification characteristics of using biological packed columns were studied.The effects of inlet concentration,gas flux and recycled sprayed liquid density on the odor removal efficiency were investigated.The interaction of different components of the odor was researched by supplying a single,double-mixed(hydrogen sulfide,ammonia) or triple-mixed gas.The results show that: the hydrogen sulfide removal efficiency is 100%;ammonia purification efficiency decreases when the gas flux or inlet concentration increases;hydrogen sulfide contributes to ammonia removal,but trimethylamine has competitive inhibition of ammonia elimination.The biological removal of trimethylamine is effective;hydrogen sulfide and ammonia can hardly affect the trimethylamine removal. |
