| 中文摘要 |
| 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。 |
| 英文摘要 |
| 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. |
