A SURFACE RUNOFF CLEANING PLANT FOR THE TERRITORY OF THE NOVOROSSIYSK SEA PORT
DescriptionThe article considers scheme of sewage treatment plants AG-STOK of Novorossiysk trading sea port, designed to clean the surface runoff from the territory of industrial sites and residential areas to the norms of discharge in the drainage network. The installation includes a well-separator, a storage tank, mechanical cleaning of solids on a mechanical filter, filtration through a filter with granular loading and filtration through a filter with sorption loading. The treated runoff, which corresponds to the conditions of discharge into the urban drainage network, accumulates in a tank of clean water and is diverted to the storm sewer network. There are: the scheme of treatment facilities, the explication of equipment, a photo of a mechanical filter, a filter with a granular load and a filter with a sorption load. The indicators of surface runoff correspond to the norms of the maximum permissible discharge

IMPROVING THE PHOTOELECTRON SEPARATOR WHEN SEPARATING SUNFLOWER SEEDS
DescriptionTraditional processing technology of piles of sunflower seeds in agriculture requires consecutive through the whole set seed-cleaning machines installed in seed-cleaning complex or aggregate, for each stage of which are organic impurity, broken seeds, shriveled and milled seeds. The seeds of the main culture are subjected to long-time effects of the working bodies, leading to their injury and the necessity of manning the production line machines the same performance that is not rational. One of the ways to enhance the process of separating the seed material in seed-cleaning complex is its fractionation by applying photoelectron separator at the final stage of seed treatment. Qualitative performance of photoelectron separator on fractional technology showed that the purity of the seeds varied from 99.80 up to 99.98% depending on their size Ø7–Ø8 mm Ø8–Ø9 mm, respectively. The content of seeds of the main culture in the waste ranged from 65.60 % (fraction Ø7–Ø8 mm) to 68.83 % (fraction Ø8–Ø9мм). The weight of 1000 seeds ranged from 117 g (fraction Ø7–Ø8 mm) to 146 g (fraction Ø8–Ø9мм). Seeds obtained in fractions and existing technology (without fractionation) meet the requirements of GOST. The output of treated seeds in the fractionation varied from 93.20 % (fraction Ø7–Ø8 mm) to 92,90 % (fraction Ø8–Ø9 mm). Comparative tests of photoelectron separator F 5.1 in seed-cleaning complex by the division of sunflower seeds on the existing and fraction technology showed that in the photoelectron separator it is necessary to use fractional technology. So, as it allows reducing the content in waste of seeds of the main culture and increase the qualities of seeds depending on their size fractions

HARDENING AND SOFTENING OF CLAY SOIL
DescriptionHardening of clay soil manifests in the form of increase of the resistance of sample to shear deformation. The shear tests of normally compacted and overcompacted soils give values of peak strength at small strains and long-term strength at high. A shear test with constant strain rate of deformation (CRD) with continuous recording of resistance encounters uneven resistance change and the cyclical rate of change of resistance (RCR). The identification of cycles of the SIS allowed us to divide the deformation in each cycle for elastic and inelastic, corresponding to the ascending and descending branches of cycle. On an interval of the total resistance, the increases of the increment of inelastic strain are positive up to some critical value of the total deformation of the sample at which their sum reaches a maximum. This maximum is adopted as a measure of hardening. With further shearing of the sample, inelastic increments are negative, and their sum is monotonously decreases and reaches negative values for the total destruction of the sample. This value is taken as the softening. A symptom of total failure of the sample is the decline of absolute values of inelastic increments of resistance to zero. In general, the trend of the increments of inelastic and elastic increments of the resistance of the sample indicates the development of the destruction of the soil sample on the sliding surfaces and, in particular, yielding of the total surface. The sum of elastic increments of the resistance monotonically increases throughout the shear

CONTROL OF TECHNOLOGICAL PROCESSES BASED ON SCADA
DescriptionSCADA is modern information technologies. The monitoring and control of various technological processes in industry and in agriculture are possible thanks to these technologies. The training complex is created to study features of SCADA systems. The domestic SCADA Trace Mode The domestic SCADA Trace Mode is used in this complex. Students study the abilities of this system on the example of the heating process. Trace Mode controls humidity and regulates temperature in a closed space. Its advantage consists in creation of automatical workstation. There are a device for accurate temperature measurement; Video, which repeats the work of the heater on the screen of the workstation. There is also a trend with graphs of humidity, of temperature; there is an alarm report with information on the magnitude and timing of the process failure. Among them, there is a device for accurate temperature measurement; video, which repeats the work of the heater. There is the picture with graphs of humidity, of temperature and of the target on a temperature also, there is a report of the alarms about information on the magnitude and timing of the failure the process. A distinctive feature of the developed this complex is to provide students opportunities for acquiring skills of design and operation training of the automated control system of technological process of heating with the holding of tests in real time. After studying one SCADA system, students are easily transferred to work in another system, for example, Master SCADA, domestic producer InSAT
