| Résumé : |
Some of the basic properties of tannery sludge were examined by using GC-MS, atomic absorption spectrophotometry and other methods. The effect of enzyme pre-treatment for tannery sludge was studied. The results showed that the alkaline protease 2709 and neutral protease As.1398 can effectively prompte the soluble chemical oxygen demand of tannery sludge.
Alkaline protease 2709 enzymatic pre-treatment can promote anaerobic digestion of tannery sludge. It can increase the rate of decomposition of organic matter by 23.01 %, and increase methane gas production by 144.89 %. Used together with ultrasound pre-treatment alkaline protease 2709 and can promote anaerobic digestion and increase the rate of decomposition of organic matter by 65.63 % and gas production by 425 %. |
