Ecological and climatic features of recycling in the Arctic zone of Russia

The ecological safety of the population and the natural environment of urbanization territories largely depends on the functioning of water disposal systems. The climatic features of the Arctic zone of the Russian Federation, namely a steady increase in air temperature with a low degree of precipitation, indicate the prospects of using solar energy to optimize the functioning of drying beds. The main specificity of these structures is a direct dependence of the waste treatment process on the cumulative effect of air temperature and precipitation (climate coefficient CC (μ)). The paper analyzes the regulatory requirements for the CC (μ) ranking for the territories of the Russian Arctic. The dynamics of CC (μ) was studied according to the data of weather stations deposited in the YOD archives Web Aisori-M VNIIGMI-WDC for the periods of action of regulatory documentation, i.e. 1958–1985 and 1986–2012. An increase in the mean annual air temperature between these periods was 0,3 to 2,0 °C. The range of values corresponded to the standard step of the CC (μ) ranking. The dynamics of the average annual precipitation changed significantly, which became a dominant factor, the influence of which changed the CC (μ) value and its territorial zoning in 1958–1985 compared to 1986–2012. Within the single zone of the normative CC (μ) corresponding to 0,7–0,8, the increase in CC (μ) for the territories of Vorkuta, Salekhard, Naryan-Mar and Turukhansk varied from 0,7 to 0,9. An increase up to 1,0 was recorded for the territories of Arkhangelsk and Murmansk located in the western part of the Russian Arctic within the zone of 0,8–0,9 standard CC (μ). The effect caused by decreasing amount of precipitation can be used by community services to increase the input of sludge mixture (higher load and lower operating costs) or to reduce the area of drying beds.
