[The wastewater treatment significance in the control sanitarian and epidemiological state of environment].
The municipal wastewater consist of organic, inorganic and biological contaminations. The most of human and animals pathogens are found in municipal wastewater responsible for water-borne and waterwashed diseases. Wastewater biological treatment is effective methods to reduce the transmission route of this pathogens. Different kind of methods (microfiltration/coagulation) and technology (aerobic/anaerobic stabilization) treated municipal wastewater, secondary effluent, primary and excess sludge are used to inactivation viruses, bacteria and protozoan. Chemical disinfection with CaO significantly affects inactivation of helminthes eggs during the hygienization of sludge. However the efficiency of pathogens disinfection particularly depend on contact time and concentration of disinfectants.
