    Abstract The article deals with the development of new eco-innovative technologies, evaluation of their effectiveness and the widest possible awareness of those categories of people who could effectively use the proposed technologies. It was found that the personal position of economic entities is the core of the structural organization of psychological readiness for ecologically oriented innovation and is manifested in the forms of free ecologically oriented will. The paper discusses the main methods of removal of nutrients from wastewater, presents promising technologies and techniques. It contains recommendations for optimal conditions for the precipitation of ammonia nitrogen from an ion exchange regenerator for further use as an ammonium fertilizer. The maximum efficiency of ammonium nitrogen removal has been established According to the results of the best options, the deposition of real ion exchange concentrates was carried out. The humidity level was set during the drying of mineral fertilizers. The moisture content determined the content of sediment, which is close to the number of water molecules to the formula of the fertilizer MgNH4PO4 ∙ 5H2O. Complex phosphate fertilizer struvit is characterized. A comparative agronomic evaluation of synthetic struvite was performed. The influence of struvite on the processes of germination of cultivated plants is carried out. The results show that the method of obtaining struvite does not significantly affect the processes of wheat germination, and the determining factor in the effectiveness of fertilizers is the method of its application and dosage.

    Abstract One of the approaches to reduce the level of anthropogenic pressure on natural ecosystems is to form a network of protected habitats in areas that are intensively used by humans. An attempt was made to determine the abundance of flora and fauna and environmental efficiency in the context of intensive agricultural development in the small Podillya reserve «Ivankivskyi». The flora and fauna of the territory on the outskirts of the village Ivanky of Vinnytsia district (Lypovets territorial community) were studied with the help of generally accepted and modified methods. It was conducted to determine the environmental value of the territory, the possibility of functioning within its protected area and at the same time preserving the forms of traditional use by the locals. The birds of the territory as the largest structural component of its fauna are studied in the most detail. The factual material was collected during field research for all the seasons of 2019-2021. Materials of scientific publications, professional literature, oral reports of specialists, etc. were processed. For all species of birds, the nature of the stay on the territory, belonging to different ecological and faunal groups were established: by nesting place and dominant food spectrum. The flora and fauna of this territory have not been studied yet, as well as its environmental value has not been determined. Animal species that are protected by the Red Book of Ukraine, international protection conventions are identified. The results of the study testify to the fact that a specific floral and faunal complex was formed within the studied area, which includes 105 species of higher vascular plants belonging to 75 genera, 26 families and 3 divisions: division Equisetophyta (1 species), Pinophyta (2 species), Magnoliophyta (102 species); 82 species of animals of the Chordata type: class Amphibia (2 species), Reptilia (1 species), Aves (68 species), Mammalia (11 species). The results presented in this publication can be the basis for the organization ...

    Abstract In work the exchange capacity and the selectivity of different ion-exchange products regarding the ammonium ions in purification processes were measured; the regenerative preparation compounds influence on efficiency of conduction of ion-exchange products regeneration was learnt. The adsorption processes were adapted to known technological schemes of sewage and polluted surface water purification that was polluted with ammonium ions. There were measured the technological aspects of water purification by using adsorption on natural dispersed sorbents. The technological schemes of drain water purification from ammonium ions were developed. The method of simultaneous removal of highly concentrated nitrogen and phosphorus was analyzed by physical and chemical precipitation, forming struvite, a by-product of magnesium ammonium orthophosphate hexahydrate. The analyses were done at various molar ratios of magnesium and phosphate ions and at various pH values. The comparative thermal analysis of chemical precipitation products and pure struvite was performed. The optimal conditions were identified to experience the maximum efficiency of simultaneous removal of ammonium nitrogen and phosphate ions from wastewater, forming MgNH4PO4·6H2O.

    Abstract The article deals with the main methods of nutrient removal from wastewater, as well as presents promising technologies and techniques. Struvite was characterized by a complex phosphorus fertilizer. The influence of struvite on the processes of germination of cultivated plants was investigated. The possibility of creating a growth substrate as an inexpensive and effective alternative to the disposal of the man-made wastes that contain an organic component was identified. The composition of the growth substrate was selected to ensure its functional properties. The growth substrate was tested by bioindication. Subsequently, the modification of the substrate by adding natural sorbents.

    Abstract This work is dedicated to development of scientific technologies of wastewater purification of different industrial enterprises from chrome ion by the way of adsorption with the help of bentonite from Cherkasy field in dynamic conditions. Perspective and efficacy of bentonite clays application for wastewater purification are confirmed by their advantages over other sorbents, that is: they win in accessibility, cost, and possibility of regeneration and multiple usages. The level of wastewater purification during adsorption with a stationary sorbent layer under static conditions and under conditions of perfect mixing at different concentrations of chromium ions (III) and quantities of the dosed sorbent was determined. The significant difference in the purification level ranges from 70÷87 % and is more dependent on the stock concentration of chromium ions. It has been found that the purification time of the same volumes of solutions for low concentrations is almost two times shorter under constant stirring, and of the same level at the stock concentrations of 1500mg/dm3. The technological schemes of wastewater purification from heavy metal ions contamination were developed.
