There are mainlytwokinds ofsludge in the municipal wastewater treatment plant, i.e., primaryand secondary sludges. They account for 0.3%-0.5% of the treatment wastewater quantity, if the water containing ratio of sludge is 97%. The studies on the fermentation of sludge in the literature mainly focus on the treatment of the primary or its mixture with excessive sludge. After hydrolysis and fermentation of the sludge, the VFAs that are needed for the enhancing biological dephosphorization are produced, and at the same time, the pollution of sludge to the environment is reduced. It specially makes sense that the technology of sludge acidogenesis applied to the southern municipal wastewater treatment plant where the quantity of the carbon source is low.
