This article describes a method of burning fuel without spraying through the nozzle due to the conversion of the liquid fraction in the vapor phase in vortex flow. When this occurs the flammable liquid in the vortex zone is carried out not through a calibrated orifice (nozzle), and the tube having a diameter of several tens of times larger than the nozzle diameter. This principle is equally effective can be burned as fuel commodity and pitched liquid combustible waste without fine purification.

In work various options of use of ejectors as the mixer of reagents with the purified water are considered. The ejector functioning as the jet pump allows to dose and mix reagent with waste water. At the same time hashing of reagents with water promoted by vials of podsasyvayemy air. Other option – the use of ejectors with magnetic elements. The effect of an intensification of hashing under the influence of magnetic field of various liquid mixes, one of which is conductive, was open by the author earlier for mixture of various liquid mixes. The essence of effect consists in what at the movement of electrolyte in magnetic field in solution influences ions induced electric weeding that promotes an intensification of molecular diffusion.

Presents the result of testing a hybrid wastewater treatment method with contaminants of organic nature, in particular, effluents of pharmaceutical enterprises. The method combines reagent-membrane concentration of aqueous solutions and the subsequent oxidation of organic components at supercritical water parameters. Primary concentration is based on the introduction into solution of sorption materials of organic nature and microfiltration of the resulting suspension using ceramic membranes. It is shown that supercritical water oxidation of concentrates reduces their COD to the level acceptable for discharge.

Prospects of use of flowing vortex acoustic technologies at oil pumping stations, for the purpose of an intensification of processes of cleaning of drains in comparison with traditional technologies of gravitational upholding and Archimedean flotation are proved.

Considered the possibilities of drill cuttings involvement in the processes of ecosystem functioning as parent material and soil-like materials (organolithostrates, constructozems). Model experiments were carried out with drilling waste and model mixtures that included sand, kieselgur, peat, phosphogypsum, cement and crude oil. To assess the properties of mixtures and their possible impact on the components of the environment, a water migration index was used. We revealed that optimal ratio of components in the construction design of soil-like materials was: drill cuttings (not more than 7 %), sand (not less than 20 %), kieselgur (not less than 4 %) with content of total petroleum hydrocarbon not more than 50 g/kg. Optimization of drill cutting properties let us design soil-like ground that could be organically integrate and function in the ecosystem. Restrictions on the use of newly formed substrates are the content of highly soluble salts – chlorides, which are not amenable to regulation and are not standardized in soils and grounds today.

Presents the results of research on the creation of effective technical preparations – flocculants based on polyacrylamide, modified by the physical action of microwaves with frequency 4.5 GHz on their solid phase. The change in the basic physical properties of the working solutions of flocculants was established (dissolution rate, shear stress values, efficiency and sedimentation rate). Mechanisms of microwave solid phase modification and features of dissolution of pretreated batches of solid polyelectrolyte fractions are proposed. On the basis of rheological studies of prepared working solutions of flocculants and test experiments on the flocculation of suspension a comparative evaluation of effectiveness of the action of microwaves on polyectrolyte during its preliminary preparation using solid phase and liquid phase modifications.

The possibility of utilization of silica containing mining waste is substantiated. Optimal conditions were established and the compositions were determined to obtain foam silicates based on the by-product of acid processing of eudialyte ores. Methods have been developed to improve the performance characteristics of foam silicates by improving their structure. Studied the effect of mineral additives on the technical properties of foam silicates. It is shown that the introduction of diopside and vermiculite waste into the composition leads to an increase in strength and a decrease of water absorption of foam materials.

Describes the process of creating a simple and effective tool for predicting the quality of air and water bodies. Artificial neural networks are an effective tool for predicting the concentrations of suspended particles of heavy metals. The correct choice of input and output data with a clear relationship between them is necessary to obtain reliable results. Emphasis is placed on predictions of heavy metals due to permissible level of these pollutants, which often was exceeded in Tula. For given conditions, the best results are obtained using a single-layer perception with a back propagation algorithm.

The article is devoted to the assessment of current trends in water use in Russia. The statistical poly-scale approach revealed that as a result of a significant reduction in water consumption during the crisis of the 1990s, Russia ranked among developed countries in terms of water intensity. However, the rate of decline slowed down, and industrial water consumption was reduced the least. That determines regional proportions and regional dynamics. In most regions of Russia the specific water consumption decreases. Unstable trends are observed in two polar types of regions: oil and gas regions and the republics of the North Caucasus, largely due to the low share of circulating water supply. Cities are more efficient than regions. For large cities, there is an inverse relationship between per capita water consumption and the population of the city.

Methods for assessing the state of landfills for municipal solid waste (MSW) at various stages of the life cycle and their impact on the environment are considered. The results of a study assessing the degree of stability of waste of different periods of disposal according to physicochemical, biochemical, thermal parameters are presented. Based on the results of physicochemical and biochemical parameters, the stages of biodegradation and the degree of decomposition of the waste are determined relative to the disposal period of the waste. It was proposed to assess the stability of waste in an array of landfill by a number of thermal parameters of waste: the magnitude of thermal effects, the temperature of heat generation peaks, the rate of mass loss, the ratio of specific enthalpies of dry matter (DM) and organic dry matter (ODS). A method for integrated assessment of the stability of MSW in an array of landfill was developed, including the establishment of waste stability classes, boundary values of stability indicators and periods of their achievement. The method is intended for geoecological assessment of the condition of disposal of MSW and justify the choice of technical measures to reduce emissions.

It is shown that satellite monitoring can not only successfully help to control the marine environment, but also to detect dangerous natural processes caused by exploration and production of oil and gas.

The article discusses current issues of environmental inequality in monotowns (single-industry cities), the industrial infrastructure associated with it, relating to the quality of life of the population. The nature and specificity of the impact of environmental indicators in monotowns on the socio-ecological well-being of the population, healthy lifestyle and longevity, as well as their well-being and satisfaction with life are discussed. As a research method, data from a sociological survey conducted by the authors in Norilsk in 2018 are presented. An important role in the study is assigned to such a component as the ecological situation in environmental problems. Among the most important environmental problems of the regions were identified health problems, air pollution, water bodies, poor quality food, an increase in landfills. The results showed a close relationship between environmental problems associated with industrial infrastructure and the quality of life of the population.
