  • Mô tả: The aims of this research focus on accumulation and transportation of selected heavy metals in thermophilic anearobic co-digestion municipal sewage sludge and organic waste on the laboratory scale. Organic waste was collected from market and sewage sludge was collected from Kim Nguu River in Hanoi city. Organic waste and sewage sludge were mixed on optimal anaerobic digestion ratio. The influent substrate was put into experimental equipment. During experiment, some parameters such as pH, EC were measured daily, others parameters such as COD, heavy metals concentration were measured after 3 to 5 days. The heavy metals content in influent substrates and effluent substrates were paid more attention in this research. This research discoved that the selected heavy metals content in effluent substrate which were increased with order Cd>Pb>Ni>Cr>Cu>Zn. The heavy metal content is lower in influent subtrate and higher in effluent substrate. The heavy metals were easily bleached in to eluted solution in 18 fust days of themophilic anaerobic co-digestion process with order Ni>Cd>Cu>Cr>Zn. The results of research provided data to help readers understand clearly about characteristics of municipal sewage sludge in Hanoi. Base on results of this research to develop sewage sludge troatment methods. Product after treatment could be used as fertilize for soil amendment.
