In the present study,the functional ceramsite medium(FCM) was prepared by supplementation with tourmaline to compare the effect of tourmaline in the two filter media,FCM and CM,on the growth of nitrifying bacteria,and on the formation and maturation of bioflim by d.
结果表明:添加电气石的培养基中的亚硝化细菌和硝化细菌数量明显高于未添加电气石的对照组;FCM上的生物膜熟化过程对氨氮的去除率在第14 d趋于稳定,硝酸盐氮含量从第12 d逐渐升高,分别比CM早7 d和6 d,能较早发挥生物硝化功能。
If the maturation of the polymer mother liquor can be realized in the pipeline,it will greatly reduce the investment of surface engineering,so the maturation experiments of polymer mother liquor are made in the pipeline.
利用输送管道完成聚合物母液的熟化,将大大降低地面工程的投资。
