摘要

用壳聚糖和海藻酸钠作为载体

包埋固定化硝化细菌

制备固定化小球

处理养殖水体中的氨氮

寻找了固定化硝化细菌小球的最佳工艺条件.结果表明

当壳聚糖的质量分数为1.5%~1.7%

海藻酸钠的质量分数为3%

氯化钙的质量分数为4.6%~5%

戊二醛的质量分数为1.1%~1.3%

包菌量为5~5.3 mL时

氨氮去除率达到94%以上.

Abstract

This paper is to find out the best condition of the immobilized microbial beads to treat NH+4-N in fishery wastewater

which is made from entrapping nitrobacteria with chitosan and alginate as entrapment carriers.The experiment results show that when the chitosan mass percent is 1.5%～1.7%

alginate mass percent 3%

CaCl2 mass percent 4.6%～5%

glutaradehyde mass percent 1.1%～1.3%

nitrobacteria 5～5.3 mL

the NH+4-N removal efficiency of fishery wastewater is above 94%.
