Studies of oxygen mass transfer efficiency during wastewater aeration
Pavlov I.I., Dyagelev M.Y., Isakov V.G.


To date, in the processes of biological wastewater treatment the most common pneumatic aeration system, which involves the supply of oxygen-containing gas (air, technical oxygen) under a certain pressure through the main and air distribution pipelines to various kinds of dispersants installed at the appropriate points of aeration facilities to support the processes of life activity of activated sludge and mixing of waste water with activated sludge. All types of aerators are evaluated by such an integral indicator as the oxygen transfer efficiency of air. This parameter is the ratio of the amount of air consumed to oxidize the mass of pollutants entering the biological treatment facility to the total air flow to the facility, expressed as a percentage. In this work, the efficiency of oxygen mass transfer of air into water depending on the flow rate of air fed and the concentration of suspended solids in the water was investigated. Air was pumped into the developed experimental setup under normal conditions, the flow rate was regulated by the needle valve on the flow meter. The change in oxygen concentration in the water was measured with a Multi 340i sensor. Purified and calcined keramzite sand with a fraction size of 1 to 2 mm was used as suspended solids. In a series of experiments with an air flow rate of 1 l/min for the time of water saturation with air oxygen in tap water and in water with a suspended solids concentration of 0.25 g/l there is an increase in water aeration efficiency by 16.67 %. In the series of experiments with the air consumption of 5 l/min for the time of water saturation with air oxygen in tap water and in water with the concentration of suspended solids of 0.25, 0.75, 1.25 g/l the aeration efficiency increases by 25, 18.75 and 6.25 % respectively.

Adequacy of a road design model to a real object in the context of digital transformation
Timokhovetz V.D., Babich T.G.


The infrastructure of cities, especially the largest and largest in the modern world, is constantly developing. This fact entails many consequences, including in the transport sector. Therefore, in particular, the growth in the volume of motor transport (both transit and local) directly affects the condition of the road surface. This article discusses the problem of determining the wear of the pavement in its upper layers. The paper studies a wide range of factors affecting the amount of road surface wear, the main of which are investigated in more detail, namely: the type of climate, the materials of the pavement, the characteristics of the traffic flow (speed and composition of traffic). The relationship between the parameters for further research has been established. At this stage of the work, such factors as the type of climate, the strength of the stone material, the weight of the spike (wheels of cars on winter tires) and the speed of motor transport were selected for research and more detailed study. The provision of the regions of the Russian Federation with stone materials and the conditions of their applicability have been studied. Graphs of the dependence of the weight of a spike on winter tires on the speed of movement on the example of passenger cars have been developed, an analysis of mathematical models describing this relationship has been carried out and a function has been established that most accurately describes the collected data - cubic regression. The relationship between the speed of movement, the weight of the spike and the wear of the pavement, taking into account the strength of the stone material, is established. The adequacy of the developed equations is checked. In the future, it is planned to expand the data bank on road surface wear by studying the influence of the melting temperature / fragility of bitumen, traffic intensity, trucks.

Water permeability of sand and fine clay suspension mixtures - waste product of diamond ore concentration
Nevzorov A.L., Saenko Y.V., Shiranov A.M.


For the insulation of underground structures, the creation of protective screens in hydraulic structures and on waste storage tanks sand-bentonite mixtures are successfully used. Unlike natural clay soils they are characterized by homogeneity of composition, workability, high deformation and strength characteristics, lack of shrinkage, etc. As a rule, mixtures are prepared from dry ingredients. The purpose of this present research was to study the possibility of preparing and determining the properties of mixtures of sands with a saponite-containing suspension - a waste product of concentration of the diamond-bearing ore from the settling pond of the tailings of one of the enterprises in Arkhangelsk region. Saponite is a clay mineral belonging to the same group as montmorillonite, which predominates in the composition of bentonite. For the preparation of mixtures four types of sands of different composition and genesis were used. The studied mixtures in terms of water permeability turned out to be almost identical to sand-bentonite mixtures, for example, the introduction of 16 % saponite-containing waste ensured a decrease in the filtration coefficient of sands to (1.2…15.3) · 10-5, and 24 % - to (0.4…2.0) · 10-5 m/day. There were obtained experimental dependencies of the filtration coefficient k from effective or free porosity ne and degree of pore blocking in the sand matrix δ . The first value is found by excluding from the pore volume the volume of water sorbed by highly dispersed clay and dusty-clayey particles contained in the sand, and the second value is found as the ratio of the volume of clay, dusty particles and moisture sorbed by them to the volume of pores between sand particles. The use of the studied mixtures, for example, for the installation of screens on industrial and domestic waste storage tanks, will significantly reduce costs due to the use of industrial waste and sands from local quarries, as well as the absence of the need for preliminary drying of materials.

Plate load test. Prospects for development
Ter-Martirosjan A.Z., Filippov K.A.


Plate load testing occupies an important place in the cycle of engineering surveys for construction. This is caused by the fact that they most closely reflect the operation of shallow foundations under natural or artificially transformed soil conditions. In addition to working in the field of conditionally linear deformations the plot of settlement versus load obtained in the course of plate tests can characterize the plastic, strength and rheological properties of the base. However, in modern Russian practice, their results are mainly used exclusively to obtain the deformation modulus. The purpose of this work is to search the prospects for the development of the Russian practice of plate load testing. The world regulatory framework for conducting plate tests and applying their results as well as comparison of various standards has been examined in this paper. Also it is emphasized the main differences and outlined the development prospects for Russian practice: the use of direct design methods, the determination of strength parameters of soils, the determination of undrained strength, the determination of the bed coefficient. The authors of the paper also consider a number of tasks which need to be solved for the implementation of the outlined prospects, as well as the ways of their solution. The main tasks, according to the analysis, are closely connected with considering the large-scale effect in the transition from the parameters obtained during plate tests to the parameters used in the calculation of foundations. In order to take into account the scale effect in determining the strength parameters it is promising to use the method based on the influence of average stresses on the value of the internal friction angle and in determining the deformation parameters - the method of Y.K. Zaretsky, used in the practice of hydraulic engineering.

Analysis of the water saturation influence on the strength characteristics of eluvial soils
Akbuliakova E.N., Ponomaryov A.B.


The problem of influence of water saturation on values of strength characteristics of eluvial mudstone-like clays and sandstones has been considered in the article. During water saturation of such soils significant deterioration of their strength properties can be observed. This complicates the process of arranging foundations on such bases. The purpose of this work is to compare the values of the strength characteristics of mudstone-like clays and sandstones of Perm city at natural humidity and in a fully water-saturated state. To achieve this goal, the following tasks have been solved: 1) the analysis of the problem study has been carried out; 2) laboratory testing methodology has been developed; 3) the results of laboratory tests have been processed and compared with the available data of tests on the field section; 4) the conclusions of the study have been formulated. According to the results of laboratory tests on a single-plane section, a decrease in the angle of internal friction by 28 % for water-saturated mudstone-like clays and by 23 % for sandstones was revealed. The decrease in cohesion values as a result of water saturation was 29 % for mudstone-like clay and 33 % for sandstone. According to archival data from field tests of mudstone-like clay pillars, the angle of internal friction decreased by 24.2 %, and the specific adhesion decreased by 65.4 %. The results of field and laboratory tests showed a significant decrease in the strength characteristics of mudstone-like clays and sandstones when saturated with water. The authors recommend performing foundation calculations on highly weathered mudstone-like clays and sandstones of Perm taking into account the possible deterioration of the construction properties of these soils. Assessment of the stability of slopes composed of weathered mudstone-like clays and sandstones requires an integrated approach and taking into consideration possible changes in the properties of these soils during water saturation.

Processing of rice husk ash with production of popular silicate products
Ketov A.A., Krasnovskikh M.P., Ofrikhter V.G., Zhang N.


Rice husk is a multi-tonnage waste of all countries producing rice, and its disposal is still an unsolved problem. When burning rice husks, energy can be obtained, but a significant amount of ash is formed as a waste, which is an amorphous silicon oxide with various impurities. It is the presence of impurities of residual carbon and calcium and magnesium oxides that do not allow processing rice husk ash as pure silicon oxide to obtain the demanded silicate products. The article proposes and experimentally confirms the possibility of oxidation of residual carbon by nitrates with further dissolution of the resulting product with a sodium alkali at atmospheric pressure. The separate processing of the obtained solution and sediment with the production of marketable products - a solution of liquid glass and granular foam glass is justified. A waste-free complex technology for rice husk ash utilization is proposed in order to obtain valuable market products.
