| 摘 要： | 研究了温度和反冲洗对生物滤池的影响.试验结果表明,生物活性和生物量随温度的降低而下降,有机物的去除率和去除量受温度影响不明显,温度对氨氮和亚硝酸盐氮的去除率和去除量有一定影响;反冲洗使生物量减少,同时提高了生物活性,有机物、氨氮的去除率在反冲洗2 h后基本恢复到反冲洗前的水平. |
| 关 键 词： | 饮用水 生物滤池 温度 反冲洗 生物量 生物活性 去除率 |

| Abstract: | This paper studied the influences of temperature and backwashing on bio-filter.The test results showed:the biological activity and quantity decreased with the decrease of temperature;temperature had weak influences on the efficiency and quantity of the organic matter removal,but it had some influence on the ammonia nitrogen and nitrite nitrogen removal efficiency and quantity;backwashing could decrease the biomass and improve biological activity;the organic matter and ammonia nitrogen removal efficiency wou... |
| Keywords: | Drinking water Bio-filter Temperature Backwashing Biomass Biological activity Removal efficiency |
