Abstract
The work is devoted to the study of environmental problems associated with the impact of sewage sludge on environmental components and the problems of recycling a mixture of sludge on the territory of the STP. Sewage sludge can be harmful to the environment if we do not take proper steps to dispose and treat it. The main impact on the soil during the accumulation of sewage sludge on sludge deposits of sewage treatment plants is exerted by such heavy metals as copper, cadmium, nickel, manganese, lead, zinc. Heavy metals, coming from the soil into plants and transmitted through food chains, have a toxic effect on plants, animals and humans. Therefore, it is necessary to introduce modern technologies and equipment for effective wastewater treatment in order to reduce the amount of sludge formation and methods of its treatment to reduce the negative impact on the environment and human health. The purpose of the work is to analyze the processes of waste treatment “a mixture of sludge from mechanical and biological treatment of domestic and mixed wastewater” at a sewerage treatment plants in order to minimize the negative impact on the environment, using the example of Irkutsk. An analysis of literature sources was carried out as part of a study related to the problem of wastewater disposal. Possible methods of disposal in Russia include: burial, pyrolysis, incineration, use in construction and use as fertilizer. As a result of the analysis of sewage sludge treatment at the Irkutsk STP, it can be concluded that the current method of sludge treatment using sludge cards is ineffective and has a negative impact on the environment. Based on the considered methods of treating sewage sludge, the vitrification method can be accepted as optimal, which can solve the problem of treating sewage sludge at the Irkutsk STP.
