RATIONALE OF VARIANT OF BIOLOGICAL WASTEWATER TREATMENT FOR THE CONDITIONS OF YAKUTIA

The paper presents a theoretical rationale for organizing wastewater treatment suitable for the conditions of Yakutia. The presented topic is relevant due to the fact that the development of urbanized city areas significantly affects the anthropogenic load on natural ecosystems, primarily on aquatic ecosystems. In this regard, approaches to wastewater treatment and efficient waste disposal are being developed and improved. Presented is variant according to which wastewater treatment is represented by three stages: mechanical, biological and waste processing. The presented activities can serve as a rationale for choosing a method of wastewater treatment to obtain fertilizers for plants. Composting technology is proposed for the production of fertilizers; this technological stage of production allows for the efficient utilization of the solid fraction of waste.
