摘要/Abstract

摘要： 将一株反硝化细菌与一株光合细菌以不同比例混合后，用海藻酸钠固定，加入到滤料基质为生物陶瓷的净化单元中，对实验室养殖海水进行封闭循环式净化，用硝酸盐、亚硝酸盐、铵盐作为净化指标，观察其净化效果。结果表明，光合细菌的添加量为反硝化细菌的75%时，对铵盐的净化效果达到了79.72%，硝酸盐的去除率为90.61%，亚硝酸盐的去除率为77.06%。且在氨氮浓度负荷较低时也可以有较好的净化速率。

Abstract: To determine the optimum proportion(R/ H ratio)of two bacterial strains, the Rhodovulum sulfidophilum and the Halomonas alimentaria were immobilized with sodium alginate and added to purifying bio-ceramic units in different proportions. The purification effects was tested in the recirculation aquaculture seawater system by observing the removal rate of nitrate, nitrite and ammonia as the purification index. The results showed that a highest removal rate of nitrate and ammonia at a R/ H ratio of 75%, even in the water conditions with lower ammonia concentration. At the R/ H ratio, the removal rates of ammonia, nitrate and nitrite were 79.72%, 90.61% and 77.06%, respectively.
