摘　　要：以洗衣粉废水中的LAS为处理对象,研究了PVA-硼酸化法固定化微生物细胞的物理特性、废水处理特性及相关特性。其多孔结构、高机械稳定性、良好的贮藏性和活性可恢复性、污泥产量少及固定化增殖细胞的性质等说明PVA是有开发实用价值的廉价包埋剂。Using the entrapped immobilized cells for treating wastewater is a new technique of biological treatment, but the entrapping agents are so expensive that application of them will be limited. The authors have developed polyvinyl alcohol (PVA) as an entrapping agent with PVA-boric acid method, and have prepared porous PVA-pellets for treating detergent wastewater. The results show that the PVA-pellets have high mechanical stability, good preservative ability, good recovery of activity, nearly no sludge produced, and viability of entrapped sells.
