“…Опубліковані дані [9][10][11], що стосуються очищення промислових стічних вод, дають змогу стверджувати, що цим питанням приділяється мало уваги як із теоретичного, так і з практичного боку. Тому вивчення проблеми очищення згаданих стоків (а саме м'ясопереробних комбінатів) є надзвичайно важливим і актуальним у наш час, а розробки в даному напрямку є перспективними і заслуговують детального вивчення.…”

“…The equipment used at many oilproduction facilities is quite outdated, causing an increased level of environmental contamination affecting air, water and soils. In the context of water contamination, it should be understood that any oil production facility generates a wide range of contamination agents at all technological stages [3][4][5][6]. The suspended tissues of sunflower seeds and oil emulsions are the main water pollution agents generated at such factories.…”

“…Moreover, it does not control the release of environmentally dangerous volatile decay products into the atmosphere. Simple filtration, adsorption, electrofiltration, forced oxidation and some other technologies are tested and used widely to increase the efficiency of the oil-production wastewater treatment [4][5][6][7][8][9]. It should be emphasized that some porous wastes or byproducts of the coal refinery are considered as promising adsorbents for such technologies [5,7].…”

“…Based on the nature and properties of the water pollution agents present in this type of wastewater, it is expected that adsorbents with hydrophobic or mosaic surface structure should exhibit a comparatively high pollution extraction activity. It is known that coal-like materials are among such adsorbents [5][6][7]10], and therefore, their adsorption performance should be investigated to address the above mentioned issue. In this paper, the results of the oilproduction wastewater treatment by anthracite are reported.…”

The efficiency of anthracite treatment of the wastewaters formed at the sunflower oil production is investigated and discussed in comparison with other water cleaning technologies. It is found that a comparatively small amount of anthracite (10-15 % of the wastewater mass) ensures efficient decontamination and eliminates up to 70 % of the wastewater pollutants. This method does not require any extensive changes in the production technology and can easily be incorporated at the existing production facilities. This efficiency is based on the double-nature structure of the anthracite surface, consisting of the hydrophilic and hydrophobic areas. The former ones ensure a high wettability of the adsorbent and the release of some inorganic ions that provide coagulation of the emulsified contaminants. The latter ones ensure adsorption and extraction of the dissolved and emulsified organic pollutants of the wastewater. The used adsorbent can be filtered out after the extraction and then disposed of in an environmentally safe way through incineration as an admixture to the regular coal fuel.

Current environmental and socio-economic problems related to unsatisfactory quality of sewage treatment have been investigated in the paper. It is noted that the search for optimal ways of neutralization of negative consequences of economic activity is an integral component of the strategy of life support development. The characteristic of the current state of the wastewater of Ukraine and Kharkiv region is given. The economic feasibility of using water-soluble environmentally friendly sorbent at the physical-chemical purification of sewage from ions of heavy metals is calculated. It has been proved that it is possible to receive a complexing agent with a much lower cost in comparison to synthetic analogueues on the basis of brown coal the significant reserves of which Ukraine obtains. It is demonstrated that application of the combined method of ultrafiltration with complexation combining when using complexing agents based on humic substances of lignite allows to increase the degree of purification from heavy metal ions significantly. It has been established that the level of coordinated innovations in industry, as well as the volume of capital investments for the extraction of brown coal of Ukraine and the development of water protection activities is insufficient. The importance of its increase is justified. The economic efficiency of the humic substances obtained from the lignite of the Oleksandriiske deposit usage for the binding of heavy metal ions using the complexation-ultrafiltration method was determined. It was noted that organization of a new modern production of effective reagents based on brown coal will lead to creation of additional jobs and will ensure compliance with drinking water quality standards, as well as to improve the ecological state of natural water sources. A new production will have a beneficial effect on development of brown coal mining regions infrastructure.
