| 摘 要： | 以污泥与垃圾焚烧厂渗滤液为原料，通过小瓶批式试验，考察了垃圾渗滤液的添加量以及渗滤液初始pH对联合厌氧消化产氢的影响。结果表明:未添加污泥的渗滤液本身也可以在厌氧发酵过程中产氢。而污泥与垃圾渗滤液联合厌氧发酵，当渗滤液初始pH为5.20时，添加90%的渗滤液体系产氢量最大，为201.58 mL，最大产氢速率也最高，为9.56 mL/h；当初始渗滤液pH为4.47时，最大产氢量出现在渗滤液添加剂量为60%的样品，为57.73 mL，随后减小，但最大产氢速率在添加40%的渗滤液达到峰值，为5.11 mL/h。

| Abstract: | In this paper, sludge and incineration plant leachate were used as feedstocks for anaerobic hydrogen fermentation by vial batch test, and influences of feedstock proportion and pH of leachate on stability of co-anaerobic fermentation and hydrogen production performance were investigated. The results showed that the sole leachate without adding sludge could also produce hydrogen during anaerobic fermentation. While, when the initial pH of leachate was 5.20, the maximum hydrogen production performance and maximum hydrogen production rate were obtained in co-anaerobic fermentation tests, with the addition proportion of leachate at 90%, and the corresponding peak values were 201.58 mL and 9.56 mL/h, respectively; when the initial pH of leachate was 4.47, the maximum hydrogen production performance occurred at the leachate adding proportion of 60% (57.73 mL) and then declined, while the maximum hydrogen production rate reached the peak value with the addition of 40% leachate, which was 5.11 mL/h. |
