“…Использование углей на базе отходов ОСМ и ДЖД характеризует эффективность очистки в 71.1 и 50.0% при близких величинах С ОУ , составляющих 84.0 и 90.0 мг/дм 3 на 8-й и 10-й минутах контакта фаз соответственно. Последующий их контакт с образцами сточной воды вызывает рост показателя С ОУ , обусловленный явлениями вытеснительной сорбции [18]. Углеродминеральный адсорбент на базе РШ демонстрирует высокую (практически 100%-ную) эффективность очистки при обработке стока с С ОУ =42 мг/дм 3 и наиболее длительную (наименее интенсивную) кинетику процесса.…”

The sorption capacity of modified activated carbon is investigated; the possibility of creating a sorbent for iron (II, III) in water bodies with a purified water yield of up to 0.01 mg/l is shown. A sulfogroup was used as a modifier and a complexing agent. To date, thousands of sorbents are produced with various matrix materials, functional groupings, ways of fixing them, containers, mechanical properties, granulation and other characteristics. The choice of the optimal sorbent depends on the task assigned to the researcher. To a large extent, the choice of a sorbent is determined by the nature of the micro–component - the form of existence of this component in solution, the size and charge of an ion or molecule, the ability of this form to react with functional groups or directly with the surface of the sorbent. When choosing a sorbent, it is necessary to take into account the concentration mode. Thus, after sorption extraction under static conditions, the sorbent concentrate should be easily separated from the mother liquor; when used in dynamic mode, it is undesirable to use strongly swelling sorbents, as well as too small fractions of sorbents. In combined techniques, where the first step is concentration, and the second is quality control of purified water, spectroscopic methods such as spectrophotometry, atomic absorption spectroscopy (AAS), atomic emission spectroscopy with inductively coupled plasma (NPP-ISP), mass spectrometry with inductively coupled plasma (MS-ISP) can act, the possibility of rapid and quantitative elution of elements. The development of express and simple methods of water purification from heavy metals, in particular, from the widespread iron (II, III) cation in natural and drinking waters is an important task of analytical chemistry. This is due to the high prevalence of iron in environmental objects and the biomedical effect of an excess of its ions on the human body.

It has been shown that with air transportation rise it is necessary to increase the efficiency of storm and wastewater purification from the territory of the airports and other air enterprises. It is suggested to use higher aquatic vegetation to protect the environment from airborne pollutants into natural water reservoirs. For further step of final cleanup it is proposed to use aquatic hyacinth – Eichornia. The rationalization for the plant selection is provided, its essential characteristics and the way for extracting pollutants out of the aquatic environment during the metabolism process are described. The technique of experiments on determining the effectiveness of biological wastewater purification within the conditions of the central part of the country is discussed in terms of Moscow region. The measurement results of suspended materials and petrochemicals concentrations in water before and after purification in sediment ponds are presented. The effectiveness of biological purification is shown. The possibility of using water hyacinth for purification of some superficial water reservoirs is also outlined. It is recommended all the year round to use protecting constructions (covers) in open purification plants, then under protected conditions metabolism processes can proceed in the rhizome, stems and foliage of the vegetation even in the autumn-winter period. It is proposed to recycle the used biomass for commercial purposes as a livestock fodder additive under the certain conditions that have been defined. The algorithm of preserving seedlings in the cold season and their subsequent planting in water reservoirs in spring is discussed. It is economically feasible to use biological final purification by aquatic hyacinth but observing the unusual environmental safety measures that have been formulated is required. Practicability of further prospective work on producing specialized ecosystems involving higher aquatic vegetation for nature-like integrated purification of certain types of wastewater was underlined.
