摘　　要：PVA凝胶小球是一种亲水性好、具有良好细菌栖息性的新型微生物固定化载体。以PVA凝胶小球为载体,分析研究其在废水厌氧、好氧及脱氮生物处理工艺中的应用现状,指出PVA生物处理系统具有微生物富集量高、系统启动快、容积负荷高、CODCr及TN去除率高等明显的技术优势。针对不同类型废水开展PVA生物处理工艺基础试验研究以及工程化实践,是一个值得关注的发展趋势。PVA-gel beads are novel efficient hydrophilic immobilized carriers of microorganisms owing to its excellent biocompatibility. The application status of PVA -gel beads in biological treatment processes of wastewater including anaerobic, aerobic and denitrification was studied and analyzed, it was pointed out that, PVA biological processes have obvious technical advantages of high enrichment of microorganisms, fast system start-up, high volume loading, and high removal rates of CODCr and TN. Therefore, carrying out basic experimental research and engineering practice of PVA biological treatment processes treating different kinds of wastewater is a development trend which deserves attention greatly.
