Abstract

The phenomenon of carbon resource insufficiency is a common problem in municipal wastewater. In this study, primary sludge which came from primary sediment was used for generating carbon resource by anaerobic hydrolysis acidification process. In the condition of 35°C, HRT=28 h and SRT=3 d, ρ(SCOD) and ρ(VFA) of effluents reached the peak value at 975.8 mg/L and 516.4 mg/L during the operation time. When the alkalinity was 725 mg/L and pH was 7.12, hydrolysis acidification process could keep the stable state of hydrolysis acidification efficiency. Appropriate alkalinity and pH value were the key parameters of hydrolysis acidification process for stable operation. When the hydrolysis acidification process was fluctuated, the changes of ρ(SCOD) and VFA were previous to the alkalinity and pH value.
