Description
The amount of sewage sludge produced in municipal wastewater treatment plants in Japan is increased as the increasing population every year. Therefore, the introduction of the sludge solubilization is being hastened. A new process, in which subcritical water process was applied to hydrolyze and solubilize the excess sludge whereafter phosphorus and methane were recovered by MAP and UASB method respectively, was developed by our research group. It was confirmed resource recovery rate from the excess sludge by subcritical water process combined with MAP process and UASB process. A subcritical water process was applied as pilot plant installed in a sewage plant of Ube city, Yamaguchi prefecture. Solubilization rate was approximately 60% by the pilot scale plant. In addition, the phosphorus and methane were recovered by MAP process and UASB process from the solubilized sludge. According to the experiments results, it evaluated that phosphate recovery reached approximately 85% by MAP process. Moreover, it confirmed that COD removal rate reached approximately 50% by UASB process.
