Abstract
Pollution of surface water bodies poses a threat to the environment and human health. After improper wastewater treatment at municipal enterprises, mineral and organic pollutants gradually accumulate in water bodies, which in turn worsens the ecological situation and leads to outbreaks of infectious diseases. The reason for periodic violations of the operation of treatment plants is the imperfection of the technological regime. Therefore, there is an urgent need to improve the efficiency of existing biological treatment facilities by means of measures that ensure compliance with environmental requirements for urban wastewater treatment. Chlorine or its compounds are used as disinfectants: chlorine dioxide, sodium hypochlorite, calcium hypochlorite and others. Methods of wastewater disinfection using chlorine dioxide and sodium hypochlorite are considered in the work. The main advantages and problems of using these methods in comparison with the traditional use of chlorine are highlighted.
