Wastewater treatment and disposal of individual residential buildings in agriculture

In the conditions of limited possibilities of traditional regulation of production processes in bioagrocenoses it is necessary to find ways to increase their potential yield due to excessive man-made resources such as sludge from recycled wastewater. Ecological technologies of waste-free production, including the sludge sediment utilization as bio-fertilizer on agricultural fields, are a very promising direction of stabilizing the degradation processes of reducing soil fertility as well as increasing the moisture capacity, which is especially important for arid regions of the world. With the growth of suburban settlements the problem of high-quality wastewater treatment of individual buildings and, accordingly, the ecological well-being of these areas has become so urgent that it requires the development and creation of modern compact bio-cleaning modules, which should provide deep destruction of biogenic elements and possibility of secondary use of man-made resources without restructuring existing septic tanks and periodically exporting wastewater. In particular, it is a possibility to use purified water for irrigation of household plots or other technical needs, and to use sludge as a biofertilizer enriched with macro- and microelements. Ecological technologies of waste-free production, including the utilization of sludge from biological stations on agricultural fields as a bio-fertilizer, are very promising ways of stabilizing the degradation processes of reducing soil fertility in addition to increasing their water-holding capacity. Studies on the impact of various doses of the bio-fertilizer on the water-physical properties and the degree of soil contamination, as well as on the quality and yield of potato tubers cultivated for seed in the arid climate of the Lower Volga region confirmed its high efficiency and environmental friendliness. © 2019 Latvia University of Agriculture.
