The study of the dynamic model of the distribution of labor resources by region in conflict interaction

The introduced models turn out to be the development of forces and resources allocation in municipal economy branches if a lot of interests appear in a competitive case. The models combine the reasonable level of adequacy with the practical application in solving the problems. The plans of labour force allocation can be complied on their basis.

Developing efficient methods of mixing during chemical treatment of wastewater suspension

Проблема утилизации осадка сточных вод в последние годы становится все более актуальной для коммунального хозяйства. Приведены результаты исследования процесса суспендирования осадка известьсодержащим реагентом Дезолак, определены размеры твердых включений, что позволило рассчитать необходимую скорость вращения перемешивающего устройства: средний заутеровский диаметр частиц составил 55 мкм, плотность твердой фазы – 2211 кг/м3. Для эффективного суспендирования реагента необходимо обеспечить угловую скорость мешалки не менее 0,03 м/с. Исследованы основные критерии подобия для масштабирования аппаратов, определено, что при выборе мешалки следует учитывать критерий Фруда Fr, так как именно этот показатель для трех исследованных реакторов практически постоянен. На основании проделанной работы определено, что отношение мощности к объему перемешиваемой жидкости не может являться критерием для расчета аппаратов, оснащенных перемешивающими устройствами GMS: для данных мешалок справедливо снижение мощности на перемешивание с увеличением размеров аппарата. In recent years the problem of wastewater sludge disposal has become more and more urgent for the municipal economy. The results of a study of the process of sludge suspending with Dezolak, a lime-containing agent, are presented; the size of solid inclusions is determined to provide for calculating the required rotation speed of the mixing device: the average Sauter particle diameter was 55 μm, the density of the solid phase was 2211 kg/m3. For effective chemical suspending the angular velocity of the mixer should be more than 0.03 m/s. The main similarity criteria for scaling the apparatus were investigated; it was determined that while choosing a mixer, the Froude criterion Fr should be taken into account, since that very indicator was practically constant for the three investigated reactors. Based on the work done, it was determined that the ratio of power to the volume of the mixed liquid cannot be a criterion for calculating devices equipped with GMS mixing devices: for these mixers, a decrease in the mixing power with an increase in the size of the device is valid.

Improvement of a plant for recycling polyethylene and polypropylene waste

This article deals with the problem of recycling polymer waste. It is global in nature and is associated primarily with the steady growth of industrial production, which is accompanied by an increase in the amount of solid household and industrial waste. This is due to the possibility of combined production, as well as products and services required in the municipal economy of the city. This article presents the ways to improve the installation for recycling waste polyethylene and polypropylene.

The article examines small and medium-sized businesses in the system of regional and mu-nicipal government. Particular attention is paid to entrepreneurship as one of the main factors in accelerating the pace of economic growth through innovative transformation of production. This type of activity is of partic-ular importance in ensuring sustainable development of the regional and municipal economy.

New Approach to the Development of Closed Nuclear Cities

The trends of the socio-economic development of closed administrative-territorial entities of the nuclear industry of Russia are determined. The impact of the diversification of the activities of the State Atomic Energy Corporation ROSATOM to diversify the economy of closed nuclear cities is revealed. A new approach to the development of closed administrative-territorial entities, based on the strengthening of participation of the State Corporation in it, measures to diversify the municipal economy in the framework of this approach are proposed. The need to use this approach in the development of strategic documents by local self-government and State Corporation is designated
