摘要
研究了餐厨垃圾与污水污泥在不同混合比例、不同污泥停留时间条件下的共消化产酸效果。试验结果表明:当餐厨垃圾与污水污泥TS比为1∶3时,SRT=1 d的反应器酸化效率最高,且乙酸含量占优,产酸效果较佳;当TS之比为1∶1时,各反应器产酸量普遍高于1∶3时,其中SRT=5 d产酸反应器,最高酸化效率达5.94,产酸量最大,且乙酸含量占优,运行效果最佳。
Under the condition of the different mixing ratios and different sludge retention time,the acid production of co-digestion of food waste and sewage sludge was investigated. The results showed that when TS ratio of the food waste and sewage sludge were 1∶3,the reactor with SRT = 1 d the highest acidification efficiency was got,and acetic acid was dominant,which meant its acid production effect was better; When TS ratio was 1∶1,acid production of every reactor was higher than that of 1∶3. The reactor with SRT = 5 d ran the best,whose acidification efficiency was as high as 5. 94,and the acetic acid was dominant.
