| 摘 要： | 针对污泥生态床系统冬季运行效果差的问题,自行培育、分离了四株耐冷菌,测试了其生理特性.实验表明,在0℃时,耐冷菌混合菌的比生长速率可达到0.058 h-1,而中温菌为零.加入耐冷菌后,污泥生态床的冬季运行效果显著提高,Zn的去除率比不加耐冷菌时提高了25倍.

| Abstract: | In the winter, the operating efficiency of ecological beds is not satisfied. Four psychrophilic bacteria were cultivated and separated, and their physiological characteristics were tested. The experimental result shows that the growth rate of the mixed psychrophilic bacteria can reach to 0.058 h~(-1), but that of the mesophilic bacteria is zero. The operating efficiency was greatly improved after adding some psychrophilic bacteria, and the removal ratio of Zn is 25 times than that adding no psychrophilic bacteria. |
