摘　　要：利用聚丁二酰亚胺对聚氨酯泡沫体进行化学改性处理,研究改性载体固定化微生物处理高氨氮模拟废水的效果。结果表明:当聚氨酯单元与聚丁二酰亚胺单元摩尔比为10∶1时,对泡沫进行改性后聚氨酯泡沫载体亲水性能良好,且具有较高的微生物负载量。改性后泡沫体上具有化学活性的官能团增加,有利于通过载体结合法固定化微生物细胞;,改性后的聚氨酯泡沫体作为微生物固定化载体用于模拟废水处理时,对主要污染指标呈现良好的污染物去除效果。Chemical treatment is carried out to modify polyurethane foams by polysuccinimide.The modified carrier is used to immobilize microorganism and thus to treat wastewater containg strong NH4＋-N.The results of treating effect show that the modified polyurethane foam carrier treated by poly succinimide with unit molar ratio of 10 ∶1 has better hydrophilic performance and a higher microbial load.The functional groups with chemical activities on the modified foam body have increased,which is helpful for the carrier to immobilize microorganism cells.The immobilized microorganisms are used for simulated wastewater treatment and present a good pollutant removal efficiency.
