  • 摘要: 填料是废气生物净化系统的核心组件，对净化性能有直接影响。以聚乙烯醇、海藻酸钠、腐熟植物纤维等为辅料，采用微包埋法制备出一种包埋恶臭假单胞菌复合填料，并将其装填于生物过滤塔中评价其对甲苯的净化性能。结果表明，制备的复合填料性能稳定、启动速度快、适宜微生物生长，对甲苯有较好的净化效果。生物过滤塔在空床停留时间47 s、进气负荷不高于42.00 g·(m3·h)-1的条件下，去除率可达90%以上。系统停运3 d和7 d，重新启动1 h后，去除率即可恢复至80%以上。动力学研究显示，与Michaelis-Menten模型相比，Haldane模型对使用该复合填料的生物净化过程拟合度较高。制备的复合填料理化性能好，对甲苯具有较高的净化效果，具有一定的应用前景。
    Abstract: Filler is one of the key components of the biological filtration system, which has a direct impact on its purification performance. A composite filler was prepared by the micro-embedding method with the Pseudomonas putida and other auxiliary materials of polyvinyl alcohol, sodium alginate, decomposed plant fiber etc. The performance of purifying toluene with this composite filler was evaluated in a biological filtration tower. The results show that the composite filler had a reliable property, fast start-up rate and was suitable for the microobial growth. A good purifying efficiency occurred for the biofilter packed with this composite filler, and it could reach over 90% when the empty bed residence time was 47 seconds and the influent load was not higher than 42.00 g·(m3·h)-1. The removal rate could restore to over 80% after 1 h restarting for the biofilter was out of service for 3 d and 7 d. Compared with the Michaelis-Menten model, the degradation dynamics in the biofilter could be better fitted with the Haldane model. The composite filler presented a good physicochemical property
