  • On determination of aerodynamic parameters of drying dispersed waste materials in a filter-fluidized bed apparatus

    he article is devoted to the question of selection of aerodynamic parameters of drying in the apparatus of the filtered-fluidized bed of dispersed particles – carbon-black containing wastes materials and granules of sodium salts in solution of modeling problems. The design of the studied gas pressure distribution grid fluidized bed of dispersed materials of the tray kind provides the possibility to efficiently fulfill the drying process at relatively low speeds of the drying agent. It is allowed to reduce the removal of particles of material from the bed and its exhaust into the atmosphere. The average flow rate of gas motion and the number of fluidization for the main stages of the filtered-fluidized bed of the studied materials and aerodynamic parameters (drop pressure losses) are determined. It was found the fluidization number in the range 1.25-1.5 and the bed height was about 0.25 m. The total aerodynamic drop pressure losses of the dispersed materials’ bed and had acceptable meanings within range from 90 to 130 kg / m2. For the recommended range the coefficient was equal 30-45. Data were obtained on the phases of fluidization, the values of the aerodynamic parameters of drying, and the areas of operating conditions that provide a fairly uniform circulation of the material in the layer and reliable operation of the apparatus.

  • The study of the fine dust particles distribution in the working area of ​​construction processes

    This article deals with the study of the characteristics of fine dust particles released on the construction site during the production of works using the lognormal distribution in the calculations. Particles of fine dust, less than 10 microns, represent the greatest risk when inhaled, as they can penetrate into the lungs. The study of the granular composition of the dust released in the air of the working area is approximately expressed as a function of the normal distribution curve, when the diameter of the particles is calculated logarithmically. The presented calculations in the article allow us to determine the distribution of dust on the territory of the construction site and identify the boundaries of the sanitary protection zone, when the value of dust at the border of it will correspond to the maximum permissible emissions.

  • The study of unconventional methods industrial wastewater treatment

    Of the existing methods of treating industrial wastewater (mechanical, chemical, physico-chemical and biological), it is the biological method that is of interest today, due to the fact that it is based on the ability of microorganisms and higher aquatic plants to use a variety of pollutants as a power source in the process of life, which ultimately leads to the purification of contaminated water. In the practice of wastewater treatment by the biological method, a floating plant — eichornia (water hyacinth) —was best established on the surface of the roots of which selective microbiocenoses are formed, which contribute to active biodegradation and absorption of both organic and mineral substances. The paper shows the possibility of echornia absorption of pollutants in an indoor environment and proved the possibility of purifying contaminated water with aqueous hyacinth in an indoor environment.

  • Environmental assessment of recreational facilities in Rostov-on-Don

    The environmental performance of recreational facilities in Rostov-on-Don was assessed. The object of the study were 15 parks and gardens of the city. Depending on the structure of the territory (the share of the green area, the density of tree planting), the parks were grouped into three groups. The influence of parks and gardens on microclimate parameters was studied - air and surfaces temperatures, air humidity. The greatest reclamation effect on the microclimate is possessed by parks with dense plantations (planting density of trees above 400 pcs / ha). Green spaces have the strongest influence on surfaces temperature, decreasing it by 11.4 - 13.8 ° С. The smallest changes are recorded for air temperature, which decreases on average by 1.9 - 2.3 ° C. Humidity increases by 2.7%. The presence of the effect plantations of trees at parks on microclimate parameters is proved by statistical methods.
