| 内容記述 | Anaerobic microbial degradation of organics proceeds through acidification, and then reaches to methane formation. In this research, the acidification characteristics of sewage sludge were studied with emphasis on solubilization of heavy metals. The experimental conditions employed are the temperature of 35 or 55℃, hydraulic retention time (HRT) of 1.5 or 3.0 days, and pressure of 0.1 or 0.6 MPa. The highest sludge destruction was obtained at 55℃, 3.0 days HRT and 0.1 MPa. At the normal operating pressure of 0.1 MPa, methane formation was not eliminated, leading to the pH of above 6. At the operating pressure of 0.6 MPa, on the other hand, the pH was decreased to below 6, due to the higher partial pressure of carbon dioxide. The zinc concentration in the supernatant was proportional to the SS concentration therein. The higher SS and lower pH for the pressurized conditions appear to promote the solubilization of zinc most. | |||||
