摘要: The effect of temperature on the simultaneous sewage sludge digestion and metal leaching process was studied in laboratory bioreactors 20 l working volume. results thus obtained showed that can be employed efficiently for solubilization, elimination indicator microorganisms stabilization at temperatures between 10°C 30°C. Rates pH reduction, sulfur oxidation, growth thiobacilli, solids degradation were found to decrease with temperature. Low solubilization efficiency observed 10°C; however, metals solubilized below recommended level. organic matter nutritive elements (N, P K) not significantly affected by variation fertilizer value after did change remained same irrespective *** DIRECT SUPPORT AG903078 00005
