The purpose of this study is to search the optimal mixing ratio of medium and sewage sludge, and to produce hydrogen by anaerobic fermentation. Sewage sludge is pre-treatment by heating process(80 ℃, 30 min) and then culture on 3% glucose as the carbon source. Sludge and medium are culture, in the ratio of 5 to 1, 3 to 1, 2 to 1 and 1 to1, using batch reactor during 5 days. Experimental results indicated that the hydrogen production ability of mixing ratio affected pH and organic acid. Acetic acid and butyric acid were the main by-products from the glucose degradation.
