固定化微生物细胞降解邻苯二甲酸二丁酯

The biodegradation of di-n-butyl phthalate （DBP） using immobilized microbial cells was carded out in an internal airlift loop reactor with ceramic honeycomb supports. A strain that is capable of degrading DBP was isolated from the activated sludge and identified as Bacillus sp. using 16S rDNA sequential analysis. Bacillus sp. could be rapidly attached onto the ceramic honeycomb supports. The immobilized cells could effectively degrade DBP in batch and continuous experiments. When the influent concentration of DBP was 50mg·L^-1, the effluent DBP reached less than lmg.L i with 6h hydraulic retention time （HRT） in continuous experiment. The immobilized microbial cells could grow and accumulate through the biodegradation of DBP, and the rate of degradation is accordingly increased. The possible pathway of DBP biodegradation using immobilized cells was tentatively proposed.

迪恩涡编织型中空纤维膜分离黏土悬浮液研究

研究了一种新型编织中空纤维超滤膜，分析了这种膜对纯水和黏土悬浮液的分离效果，比较了同类型中直线型超滤膜的性能差别，对不同浓度黏土悬浮液渗透通量衰减性能、渗透回收率和能量消耗进行了对比试验、结果表明，由于迪恩涡的强化传质作用，编织型中空纤维膜过滤黏土悬浮液时极限渗透流量比线性中空纤维膜高40％～110％，而单位渗透流量的能耗只有线性中空纤维膜的50％～70%，且随污染物浓度升高，极限渗透流量的改善和单位渗透流量的能耗降低效果更明显．

固定化微生物细胞降解邻苯二甲酸二丁酯

The biodegradation of di-n-butyl phthalate (DBF) using immobilized microbial cells was carried out in an internal airlift loop reactor with ceramic honeycomb supports. A strain that is capable of degrading DBF was isolated from the activated sludge and identified as Bacillus sp. using 16S rDNA sequential analysis. Bacillus sp. could be rapidly attached onto the ceramic honeycomb supports. The immobilized cells could effectively degrade DBF in batch and continuous experiments. When the influent concentration of DBF was 50mg·L-1, the effluent DBF reached less than 1mg·L-1 with 6h hydraulic retention time (HRT) in continuous experiment. The immobilized microbial cells could grow and accumulate through the biodegradation of DBF, and the rate of degradation is accordingly increased. The possible pathway of DBF biodegradation using immobilized cells was tentatively proposed.
