Kotelchuk A. Substantiation of technology preparation of domestic sewage for their use in systems of an irrigation

The dissertation is devoted to a scientific substantiation and development of new more perfect technology of additional cleaning and disinfecting of domestic sewage before their release in reservoirs or for use in systems of irrigation. The technology of additional cleaning of domestic sewage on bioreactors with concentric fibrous and polyethylene environments and contact defecation filters which is characterized by high efficiency and profitability of work is developed. More exact mathematical models of processes of water-preparation on such constructions are constructed, and on the basis of experimental and theoretical researches more expedient constructive and technological parameters of these constructions are determined and the technique of engineering calculations for them is developed. The land-reclamation estimation of the cleared and disinfected domestic sewage is executed and the opportunity and expediency of their use in systems of an irrigation that provides increase of productivity of agricultural crops in 2-4 times and a recoupment of station of additional cleaning of sewage for 4-5 years is confirmed.
