摘　　要：考察了不同的预处理方式对剩余污泥水解及厌氧消化产甲烷过程的影响。研究结果表明:低温热碱预处理对污泥的水解效果最好,剩余污泥中SCOD及可溶性总糖、蛋白质溶出效果大幅提升,SCOD溶出率达到16.6%;执行三种方式预处理后,后续厌氧消化的效率得到明显改善,剩余污泥经碱处理、低温热水解和低温热碱处理后,厌氧消化的产气量较未预处理污泥分别提高了75.6%、72.9%和83.7%。The hydrolysis and biogas production through anaerobic digestion of excess sludge was investigated using various pretreatment methods. The results showed that thermal-alkaline pretreatment had the highest efficiency. The concentrations of SCOD,total soluble sugar and protein increased significantly,with the SCOD dissolution rate of 16. 6%. Meanwhile,the efficiency of anaerobic digestion improved significantly after alkali treatment,low temperature thermal pretreatment and thermal-alkaline pretreatment. The accumulative gas production increased by 75. 6% 、72. 9% and 83. 7%,respectively,compared with the untreated excess sludge.
