为解决我国人均水资源不足、水资源时空分布不均以及水污染日趋严重的矛盾，水资源管理需要新思路、新策略。即控制水的需求，强调节水优先；加强源头控制，切实防治污染；多渠道开发水源，特别重视开发非传统水资源。

A quinoline-biodegrading microorganism was isolated from activated sludge of coke-wven wastewater treatment plant using quinoline as sole carbon and nitrogen source. It is a gram negative, rod-shaped and aerobic strain, which was identified as Burkholderia pickettii, The biodegradation of quinoline was carried out with this isolated strin. Analysis by high performance liquid chromatography and gas chromatography/mass spectrum (GC/MG) revealed that 2-hydroxyquinoline (2-OH-Q) was the first intermediate in the course of quinoline biodegradation, A novel immlbilization carrier, that is, polyvinyl alcohol (PVA)-gauze hybrid carrier, was developed. The isolated strain was immobilized by tow different immobilizing techniques and used for the quinoline degradation, It was found that biodegradation rate of quinoline by the microorganisms immobilized on PVA-gauze hybrid carrier was faster than that by the microorganisms immobilized in PVA gel beads. Kinetics of quinoline biodegradation by cells of Burkholderia pickettii immobilized on PVA-gauze hybrid carrier was investigated. The results demonstrate that quinoline degradation could be described by zero-order reaction rate equation when the initial quinoline concentration was in the range of 50-500mg1-1.

用生物流化床反应器和气提式接触氧化生物反应器处理啤酒废水时，分别从废水COD的隆解速率和去除率考察了有、无内循环时，对啤酒废水降解效率的影响，结果表明，增加内循环装置，可以强化气-液传质，明显地提高啤酒废水处理的效率。
