投加优势菌强化降解液相油烟污染物的动力学研究

以桂林市雁山镇污水处理厂取回的活性污泥作为降解模拟餐饮油烟的洗涤液，采用富集驯化的方法，从中筛选出一株能高效降解油烟污染物的真菌ZJ01并对其进行分子生物学鉴定。通过投加两种优势菌（黑曲霉和白腐菌）协同强化洗涤液生物降解油烟污染物以双曲线速度模型进行动力学研究，结果表明：ZJ01为枝孢霉（Cladosporium halotolerans），空白、投加黑曲霉、投加白腐菌洗涤液降解油烟污染物的动力学模型分别是u=（0.0109c）/（228.12+c）、u=（0.0249c）/（491.71+c）、u=（0.0124c）/（247.79+c）。真菌类饱和常数大小关系为投加黑曲霉 > 投加白腐菌 > 空白，最佳投加真菌菌株为黑曲霉。

Study on kinetics for strengthen the degradation of liquid fume pollutant by dosing predominant strains

We used the activated sludge that obtained Guilin Yanshanzhen sewage treatment plant as washing liquid to degrade cooking fume pollutants. A bacterial strain named ZJ01 with high oil-degrading efficiency was isolated from the washing liquid and identified by molecular biological methods. We added two kinds of predominant strains (Aspergillus niger, white-rot fungus) to the washings to enhance the ability to biodegrade fume pollutants, and a hyperbolic model was used to study the degradation kinetics. The results revealed that ZJ01 is Cladosporium halotolerans. The dynamic model of experiments "blank," "added A. niger," and "added white-rot fungi" was u=(0.0109c)/(228.12+c), u=(0.0249c)/(491.71+c), and u=(0.0124c)/(247.79+c), respectively. The highest fungal-saturation constant size was observed for A. niger followed by white-rot fungi and the blank;the best additive dominant strain was also observed for A. niger.
