ENVIRONMENTALLY ACCEPTABLE NORMS OF MAN-MADE LOADS ON IRRIGATED LANDS DURING WASTEWATER DISPOSAL

Abstract

Nature management is a combination of various forms of exploitation of the natural resource potential of natural and man-made systems and measures to preserve it. Its most important component is not only conservation, but also reproduction, as well as rational change in the ecological balance of natural systems.It is from these positions that it seems necessary to determine environmentally acceptable norms of man-made loads on irrigated lands during the disposal of wastewater, widely used in the practice of water supply and sanitation. The use of wastewater from industrial and municipal facilities for irrigation of land is of fundamental importance from both ecological and economic positions. From the point of view of ecology, the use of wastewater in the presence of waste-free and safe technologies for their disposal in irrigation fields for irrigation of agricultural crops can serve as the basis for rational environmental management. At the same time, the ecological sustainability of landscapes is ensured, which makes possible the long-term exploitation of natural resources without their pollution and degradation.From an economic point of view, by creating agricultural landscapes in unproductive lands, using wastewater from industrial and municipal facilities, it is possible to ensure the production of a certain amount of agricultural products, provided that the damage caused to the natural system (S) will be less than the profit (S). Under these conditions, the object of wastewater disposal is the soil, which requires the need to determine a number of environmentally effective ways to optimize the soil-forming process, which would create, in an agroecological and economic sense, a perfect technology for their disposal, taking into account the laws of nature
