中文摘要：

为了寻求高效的剩余污泥处理方法,通过不同的预处理方式或者添加餐厨垃圾的方法,考察了主动错流式MBR工艺所产生剩余污泥的厌氧发酵产甲烷效率。研究发现,低温热水解预处理剩余污泥的厌氧发酵产甲烷的最优条件是90℃热水解加热30 min,产甲烷量大概为原来的1.5倍,效率提高了50%。臭氧曝气预处理剩余污泥厌氧发酵产甲烷的最优条件是臭氧曝气时间为0.001 4 g O3/g VS,产甲烷量大概为原来的5倍,效率提高了5倍。加入餐厨垃圾对产甲烷有一定促进作用,同时对产氢有着极大的促进作用。

英文摘要：

To seek for effective excess sludge treatment method, the experiment examined the anaerobic fermentation, s efficiency of excess sludge which produced by the active cross-flow membrane bioreactor process through different ways of pretreatment method or adding kitchen waste. The study found that the optimal conditions of low temperature thermal hydrolysis process was 90 丈 h e a t hydrolysis heating 30 min,about 1.5 times of the original methane production,efficiency increased by 50%. The optimal conditions of ozone aeration pretreatment was 0.001 4 g O 3 /g VS , a b o u t 5 t i m e s o f t h e o r i g i n a l methane p r o d u c t i o n,e f f i c i e n c y i n c r e a s e d b y 500%. The addition of kitchen wastes played a role in promoting methane production, a great role in promoting hydrogen production as well.
