| Summary: | The paper considers characteristics of the activated sludge in the local wastewater treatment plant (LWTP) and
its ability to purify fully domestic sewage water in the Far North. Biochemical process of destruction of organic
pollutants is influenced by a microbial complex functioning in aeration tanks. Taking into account climatic
conditions of the region where the organic matter degradation processes are slowed, and lack of control over the
operation, efficiency and occupational safety of LWTPs, it seems to be important to study the physiological
characteristics of the bacteria used in bioremediation, and their ability to maximize the purifying domestic
sewage in the Arctic region. Undue intervention in the biosphere systems leads to disruption of the balance of
internal and external ecosystems communications. The goal of research is studying structural determination and
functioning of activated sludge bacteriocenosis of LWTP TOPAS-5 (GK "Topol-ECO") in certain physical and
chemical conditions of the habitat, and establishing completeness of cleaning process in this treatment plant. The
paper considers the structure (quantitative and qualitative composition) and function of LWTP activated sludge
bacteriocenosis functioning in the Arctic region. The estimation of the activated sludge of full waste water
treatment process of the LWTP has been given. The research's results have allowed to identify and determine the
bacterial count of physiological groups of microorganisms purified domestic sewage; to isolate from activated
sludge the bioflocculant-producing microorganisms' on the experimental medium; to evaluate efficiency of
LWTP work in the Arctic region |
