[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.
