摘要：考察了低浓度葡萄糖、乙醇和生物激活剂对生物膜修复污染河水的影响。结果表明,3种药剂对生物膜去除污染河水的COD均有明显强化作用,葡萄糖的强化作用最为明显。在22～31℃,河水流量为10L/h、气水比为10∶1(V/V)时,与空白相比,加入4.5mg/L的葡萄糖可使COD去除率提高50.3%,河水COD可由地表水V类水质变为I类水质。加入5mg/L乙醇可使COD去除率提高18.5%。在16～20℃、其他条件不变时,加入3mg/L的生物激活剂可使COD去除率提高17.9%。但3种药剂对于氨氮的去除意义不大,加入4.5mg/L葡萄糖后氨氮的去除率只提高7.7%。加入5mg/L乙醇后氨氮的去除率略有下降,加入3mg/L生物激活剂后,氨氮去除率略有提高。
The effect of glucose, alcohol and biostimulant on the bioremediation of polluted river water by biofilm was inspected. The results show that the kinds of reagents play a positive role in augmenting COD removal rate. COD removal rate increased by 50.3% after adding 4.5 mg/L glucose under the conditions of 22～31 ℃, 10 L/h of water flux, ratio of gas to water 10∶1. COD of the river water can reach grade I just from grade V according to the national standard for surface water. Under the same conditions, COD removal rate increased by 18.5% after adding 5 mg/L alcohol to the river water. The mean removal rate of COD increased by 17.9% after adding 3 mg/L biostimulant (BO). The removal rate of nitrogenammonia increased by 7.7% after adding 4.5 mg/L glucose and somewhat increased after adding 3 mg/L BO. However it decreased after adding 5 mg/L alcohol.
