| 摘 要： | 为了构建生态平衡的海水水族缸闭合循环系统，笔者设置了4种海水水族缸挂膜实验缸，缸内分别加入虾肉（腐尸法）、虾肉和硝化细菌（综合法）、硝化细菌（生物制剂法）、自然海水（对照空白缸），定期测定缸内三态氮的含量，通过三态氮含量的变化来判断缸内生物膜的成熟程度．腐尸法和综合法在15d后就能达到氨氮含量稳定，但硝酸盐含量较高；硝化细菌法氨氮含量达到稳定需要28d，而空白对照缸氨氮达到稳定需要35d．在生物膜挂膜后，加入观赏鱼进行实验，发现硝化细菌法和自然海水法所构建的水族缸氨氮含量变化较小，而腐尸法处理的水族缸易引起藻类大量出现． |

| Abstract: | The change in nitrogen in marine aquarium was studied during the maturing procedure for biofilter with rotten meat method, nitrate bacteria method, the combined of formal two and the blank method, respectively. It took 15 days to stabilize the nitrate by the rotten meat method and the nitrate-N was keeping high; and it took 28 days to stabilization the nitrate by nitrate bacteria. It was almost the same with the combinations with the rotten meat method. It took 35 days for the blank method. With fish after the mature of marine aquarium, we found that the system with nitrate bacteria and blank was performing better and the nitrogen conversion changed little. However, algae were much apt to appear in the system with rotten meat method. |
| Keywords: | marine aquarium nitrogen conversion bio-film nitrate bacteria system |
