Anaerobic digestion process has been utilized for aerobic sludge reduction and stabilization in wastewater treatment plants in Europe, United States and Japan, for which knowledge on inorganic dissolution/precipitation has not been enough to simulate or control the situations such as the mechanical failure caused by unexpected solid precipitation and the phosphorous adsorption onto solid phase. This research project has developed the inorganic dissolution/precipitation model that predicted the aqueous/solid compositions of anaerobic digestion liquor, and also proposed an inhibitory measure against the unwanted solid precipitation in wastewater treatment plants.

厌氧消化工艺在欧美日污水处理厂中已被用于好氧污泥减量和稳定化，但对无机溶解/沉淀的认识还不足以模拟或控制诸如意外固体沉淀引起的机械故障和磷吸附到固相上等情况。本研究发展了无机溶解/沉淀模型，预测厌氧消化液的水/固体组成，并提出了抑制污水处理厂不必要的固体沉淀的措施。
