Remediation of Municipal Waste Water Biocolloid Solids Contaminated by Heavy Mеtals

The study is devoted to the experimental substantiation for technology of heavy metals removal from contaminated municipal wastewater sludge by enhancing the activity of autochtonous biocenoses with formation of metabolites binding metals into stable water soluble complexes. We compare the efficiency of heavy metals removal from sludge of biological treatment of municipal wastewaters in bioleaching process with heterotrophic and chemotrophic biocenoses and chemical leaching. Moreover, we demonstrate the advantages of metals bioleaching process at acidogeneous heterotrophic metabolism.
