摘    要:采用酸性洗涤塔、生物滤塔和生物曝气池的组合工艺处理NH3、H2S恶臭混合气体,研究表明,该组合工艺对NH3和H2S有很好的去除效果,在进气流量为35 L/min,喷淋量45 L/h时,NH3进气浓度50.15~525.4 mg/m3,H2S进气浓度10.23~110.36 mg/m3时,NH3单一进气去除率稳定在99%以上,H2S单一进气去除率90%以上。混合进气后,NH3去除率几乎为100%,H2S的去除率提高至98%以上。在一定的浓度范围内,NH3和H2S之间的相互作用对两者的去除效果没有明显的影响,而且起到了相互促进降解的作用。同时,进气流量和填料层高度都会影响NH3、H2S的去除率。系统对进气容积负荷变化的缓冲能力强,在偶尔超负荷条件下运行并不能使系统崩溃,并且微生物对高负荷逐渐表现出适应性。大部分溶于水的氨由生物曝气池去除,去除率达到96.9%。

关 键 词:生物滤塔组合工艺  氨气  硫化氢  去除率  生物除臭

Abstract:A novel combined biofitter, which is composed of acidic scrubber, biofilter and biological aeration basin,was used to treat the odors mixed by NH3 and H2S. The results indicated that the removal rate of NH3 and H2S were over 99% and 90%, respectively with the odors entering singly,when the flow rate of odor was 35 L/h, the fitting spraying quantity of nutriend fluids was 45 L/h, the mass concentration of NH3 was 50.15~525.4 mg/m3 and H2S was 10.23~110.36 mg/m3. The removal rate of NH3 and H2S increased to 100% and 99%, respectively when the odors intaked mixed. In a certain concentration range, the interaction between NH3 and H2S had little influence on their removal efficiency, but promoted the degradation mutually. The removal rate of NH3 and H2S also could be affected by the flow rate and the packing layer height. The combined biofilter had a wide buffering capacity and could recover quickly in a short time of shock loading. And the microorganism in the system would adapt to the high intake volume load gradually. The ammonia solubled in liquid could be removed 96.9% by the biological aeration basin.
Keywords:combined biofilter  ammonia  hydrogen sulfide  removal rate  biological deodorization
