摘要: 以生物降解法处理阴离子表面活性剂(直链十二烷基苯磺酸钠,即LAS)废水.通过将TP-1号菌种固定在海藻酸钠载体上,采用正交试验法,以固定化细胞对LAS的降解率和降解寿命为试验指标,确定了适宜的固定化条件,并与游离细胞对LAS的降解效果做了对比试验.结果表明,固定化细胞对LAS的降解程数明显增加.

Abstract: This paper deals with the biodegradation of LAS.Taking the LAS degradation rate and the immobilized cell's degradation duration as experimental criteria, the optimal immobilization is determined by means of immobilizing bacterium TP-1 on the sodium alginate carrier and making cross-test. Meanwhile,the LAS degradation ability test is made with both the immobilized cell and free cell. The result indicates that the immobilized cell can obviously increase the degradation degree of LAS.
