| 摘 要： | 本文探讨了温度变化对高浓度焦化废水厌氧分解的影响。当温度较低时(9.2℃～11.2℃),低温耐冷菌驯化污泥较常温污泥COD_(Cr)日降解率(Da)高出2～3倍。因此,当温度下降至低温时,可通过增补耐冷菌来提高系统的降解效率。

| Abstract: | This paper discusses the temperature changes affecting the anaerobic decomposition of eoking wastewater with high concentration. When the temperature is low （9.2℃- 11.2℃）, the CODcr degradation rate of the sludge acclimated by psychrotrophs is 2 or 3 times than normal sludge. Therefore, when the temperature drops, the system degradation efficiency can be improved by supplement of psychrotrophs. |
