细菌与真菌复合作用处理臭味气体的试验研究

针对臭味气体中发臭物质的特性, 开发了一种新型的复合式生物除臭反应器.该生物反应器由2个生物反应区构成, 并分别接种不同的微生物,细菌和真菌.利用该复合式生物反应器对臭味气体的处理进行了连续运行的试验研究.试验废气中主要污染物乙酸、氨、苯乙烯、硫化氢、乙硫醇、乙硫醚的去除率分别达到97.1%, 96.7%, 96.6%, 92.1%, 78%和83%.研究结果表明, 反应器中的细菌与真菌微生物具有协同作用, 因此该生物反应器能够有效地去除废气中亲水性和疏水性污染物质.并且,不同性质的发臭物质在2个反应区内的去除效果是不相同的.

Study on Odors Treatment by the Combination of Bacteria and Fungi

The aim of this study was to establish a novel combined bioreactor for the treatment of odors. The combined bioreactor consists of two zones, one bacteria zone and one fungi zone. An experiment for the odor treatment was carried out, and the removal efficiency of acetic acid, ammonia, styrene, hydrogen sulfide,ethyl mercaptan and diethylsulfide which were main material in this experimental odor were 97 1%, 96 7%, 96 6%, 92 1%, 78% and 83%, respectively.The experimental results clearly showed that bacteria and fungi in the combined bioreactor had a synergistic reaction, therefore, the hydrophilic and hydrophobic compounds can be efficiently removed in this combined bioreactor.The monitor results indicated that the removals of the compounds with varying water solubility were different in the two zones of the bioreactor.
