| 摘 要： | 通过对暗纹东方Tun水槽中硝化细菌对NH4^ -N转化率的测定,定量了解了硝化细菌的硝化率。结果表明：过滤水槽的沙粒中硝化细菌数量平均比水中要高21倍,高出对照组10倍;沙粒的硝化率为水体的100倍;影响硝化细菌对NH4^-N转化的主要因素为温度、溶解氧和细菌数量。说明了过滤水槽的装置可以大大加强养鱼池的自净能力。

| Abstract: | The measurement on the conversion rate of nitrifying bacteria to NH 4 N were determined in the filtering trouphs of Takingfugu obscurus. The nitrifying rate of nitrifying bacteria was understood quantitatively. The results showed that the quantity of the nitrifying bacteria in the sands of the filtering trouph was 21 times greater than that in the normal water, 10 times greater than that in the controlled group. The nitrifying rate of the sands was 100 times greater than the normal water. The major factors affecting the nitrifying bacteria to NH 4 N are temperature, DO and biomass bacteria. Therefore, it is indicated that filtering trouphs can effectively self purify the fish pond environment. |
