Abstract

The releasing characteristics of VFAs, organic substances, nitrogen and phosphorus during the hydrolysis process of excess sludge, with the conditions of alkaline, presence of lysozyme and coupling lysozyme and alkaline, were investigated respectively. The results showed that more VFAs, carbohydrate and protein were released under the coupling of lysozyme and alkaline condition. The production of VFAs during 36 hours hydrolysis was 682.6 mgL ^-1 which was 4.4 times of that of the blank group, which was 155.8 mgL ^-1.
