Glucose was fermented in a chemostat under anaerobic condition inoculated by mixture of two kinds of sludges and rumen from sheep.

以两种厌氧污泥和一种绵羊胃液的混合物为接种物，对葡萄糖进行厌氧发酵。

Detailed discussions are made from the design point of view on the questions with DAT-IAT process and A／DAT-IAT process (a DAT-IAT process with pre-anaerobic reactor),such as settling／decanting time,volume of anaerobic reactor,reflux ratio,pH value,temperature,selection of decanters and namber of reactor, etc..

从设计的角度出发，详细论述了DAT-IAT工艺及前置厌氧反应器的DAT-IAT工艺(简称A／DAT-IAT)中沉淀／滗水时间、厌氧反应器体积、回流比、pH值、温度、滗水器选择及反应池数量等方面的问题。

For the two digestions of material proportion 83∶17 and 62∶38）with pH adjustment to 7.2 at the acidification stage, the stable pHs for methane production were 7.4~8.0, total VFA concentrations were 500~900 mg·L-1, propionic acid concentrations were 100~550 mg·L-1, and no ethanol production was detected.

实验结果表明，与单独利用食物垃圾以及未调节酸化阶段pH的厌氧消化相比，调节酸化阶段pH=7.2的食物垃圾与废纸联合厌氧消化能够避免挥发性脂肪酸抑制、保证消化稳定性并提高消化性能。

This result explored a new idea to solve the problem of requiring large quantity inoculums, created a favorable condition for the application of anaerobic reactor, and it was also an important inspiration for organic wastes treatment.
