摘要：

过纯种分离获得LAS优势降解菌, 以活性炭纤维为载体挂膜形成强化吸附性生物膜进行洗浴废水处理实验研究;并在动态实验条件下, 与单纯活性炭吸附和普通吸附性生物膜处理工艺进行了对比。实验结果表明:在相同的反应条件下, 强化吸附性生物膜对LAS、COD的去除率比普通吸附性生物膜高7.63%和4.2%;当进水流量为1.5 L/h, HRT为4 h, 曝气量为1.5 mg/L时, 其对洗浴废水中LAS、COD和NH₃-N的去除率分别为87.14%、85.87%和74.89%。

Abstract:

LAS predominant strains has been obtained by purebred separation process. Experimental research on the treatment of bathing sewage are to be accomplished by using ACF as carrier, so as to form enhanced adsorptive biomembrane. And under dynamic experimental conditions, the process has been compared with single activated carbon adsorption and ordinary adsorptive biomembrane treatment technology. The results show that under similar reaction conditions, the removing rates of LAS and COD by using enhanced adsorptive biomembrane are 7.63% and 4.2% higher, respectively, than that of ordinary adsorptive biomembrane. When the influent flux is l.5 L/h, HRT 4 h, and aeration capacity 1.5 mg/L, the removing rates of LAS, COD and NH₃-N from the bathing sewage by using enhanced adsorptive biomembrance are 87.14%, 85.87% and 74.89%, respectively.

Key words: bathing sewage, LAS predominant strains, activated carbon fiber, immobilized biomembrane
