  • Abstract

    The possibility of using urban sewage sludge from the silt areas of the sewage treatment facilities of the left bank of Irkutsk as a substratum in microbial fuel cells (MFС) was studied. The characteristics of voltage and current intensity generated by the microbiological preparation "Doctor Robik 109" in MFC without taking into account and taking into account the resistance of the external electric circuit are obtained. It is shown that sewage sludge with the addition of peptone and acetate (without the introduction of microorganisms-bioagents) is also capable of generating electricity. Presumably, this is due to the presence in the sewage sludge of a large number of microorganisms and their spores. An increase in the total microbial number in the investigated wastewater sediments supports the above hypothesis. The carried out researches testify to the prospects of using MFC for municipal sewage sludge utilization.
