Description
In the article, we have given the recommendations for using of the theory developed by us for the synthesis of technical systems (TS) of the process of choice knowledge from the area of knowledge. The developed methodology for the research of the real system (RS) and the synthesis of TS can be used in the development of the scientific direction - the artificial intelligence (AI). Also, for the solution of problems where you want to automate the process of choosing the desired knowledge of specific area of knowledge. The developed theory for obtaining a binary tree of nodes of the system of questions and answers will help synthesize any TS where there is a choice of knowledge of a given area of knowledge. This theory will be developed further with the self-development of TS as part of the AI system

Description
In the context of implementing programs on reducing budget expenditures for the social sphere utilities, it is urgent to intrude renewable energy sources into the practice of their energy supply. However, despite all their diversity, not all constructions based on renewable energy sources can be used under conditions of urban development. Besides, the mutable nature of the solar radiation coming on the Earth's surface requires specific forecasts and calculations of its intensity. Accurate estimation of the area solar energy potential of the generating plant proposed location allows not only to justify its parameters at the design stage, but also to predict its operating mode and to evaluate its technical and economic efficiency. The purpose of the article is to estimate the level of solar radiation for Volzhsky, Volgograd Region, at the initial stage of designing and justifying the implementation of power plants transforming renewable solar energy in urban areas. In the article, it is proposed to apply method for estimating the solar energy potential of at a specific geographic point, based on a combination of the calculation method for determining the solar radiation characteristics and actinometric measurements. Volzhsky of the Volgograd Region, like most settlements in the Lower Volga region, has a high solar energy potential: 1228.8 kWh / m² for the horizontal surface of the southern orientation of the receiving surface of power plants, which can be increased by 16.2% at its optimal orientation relative to the horizon and the sides of the world. However, the expansion of the utilization of the solar energy potential of the district may be limited to the location of the existing buildings and structures at which power plants may be located in urban development conditions

TECHNOLOGY FOR THE PREPARATION OF LIVESTOCK WASTEWATER FOR IRRIGATION OF AGRICULTURAL CROPS
DescriptionIn the article the authors propose various techniques for the preparation of livestock waste for agricultural use, particularly for irrigation. We have considered resource-saving environmentally safe technology for processing livestock waste pig farms based on the use of the reagent preparation phosphogypsum – residuals of phosphoric acid and fertilizers. The technology was tested and endorsed at the operating company LLC "Aksai field" of the Rostov region. Also based on this technology, we have offered the following technical solution: livestock wastewater is exposed to the vortex field with movable ferromagnetic particles, which contributes to more complete disinfecting effect. Further improvement of the technological scheme of training for livestock waste allowed to get more modern technical solution, including sewage treatment acidifying reagent is a suspension of phosphogypsum and slightly basic by oxychloride brand Aqua-Aurat. With the aim of reducing the cost and simplifying the technology of training we offered using a reagent, obtained from natural raw materials - silica-coagulant on the basis of nepheline instead of the low-base oxychloride brand Aqua-AuraTM. Aluminosilicate coagulant on the basis of nepheline may be used at high values of COD up to 2000 mg O/l and TBOD to 1500 mg O/l, which is a limitation for the use of such coagulants in the preparation of livestock wastewater pig farms. All the proposed technologies are based on the positions of resource and energy efficiency and environmental safety
