CA固定化亚硝化细菌氨氮去除能力的实验研究

Removing NH3-N Using Nitrite Bacteria Immobilized by CA

采用纳氏试剂分光光度法,在不同温度、pH值、葡萄糖浓度和锰离子浓度条件下,观察游离亚硝化细菌和CA固定的亚硝化细菌对亚硝化菌培养液中氨氮的去除效果。结果表明,CA固定的亚硝化细菌比游离亚硝化细菌有较强的氨氮去除能力,并且其氨氮去除能力还表现出一定的抗高温、抗酸、抗葡萄糖干扰和抗锰离子毒害的作用。

This paper relates to a laboratory investigation of NH3-N removing capability of nitrite bacteria when enwrapped by CA (sodium alginate cross-linked with calcium chloride). Result of the study shows the immobilized nitrite bacteria have a better capability of resistance against higher temperature, lower pH value, and unwanted disturbance of glucose and Mn2+.
