Harsh continental climate of Orenburg region is characterized by extremely low rates of precipitation at vegetation period, so the cultivation of flowers with protected root system has wide usage and is highly developed. The search for the optimal combined artificial soil in terms of physico-chemical composition is of great scientific and practical importance. In the short-term model experiment, variants of artificial soils are under exploration, with differing ratios of basic fillers that cover the physiological needs of flower crops when grown with a closed root system in greenhouse complexes. The results of laboratory study of artificially constructed soils based on essential materials (peat, coconut filler, river sand) and agricultural waste (horse manure, sunflower seed husk, raw fawl dung) are also presented. Combined soils are developed for the purpose of growing gerbera on “Bounty” soil and garden chrysanthemum on “Elysium” soil. These soils take into account the bioecological and agrotechnological features of greenhouse cultivation of these types of flower plants. The studied flower crops respond quite well to the physico-chemical composition of soils, showing stable growth of vegetative and generative organs.

“…With the help of this plant, most of the biogenic elements can be extracted from wastewater, such as organic carbon, nitrogen, phosphorus, potassium, calcium, magnesium, as well as phenols, sulfates, petroleum products, synthetic surfactants (surfactants). Positive examples of the use of a new aquatic plant allow us to recommend it for improving the efficiency of treatment facilities [19][20][21][22][23][24][25]. It is possible to accelerate the launch of phytostructures with higher aquatic vegetation with the help of hinged mesh modules using new plant species.…”

The development of a large city regions has a noticeable dependence of a local ecological situation. To motivate their stable growth and to create human-friendly environment the technologies of nature regeneration is needed. One of the approaches available is the implementation of hinged water modular systems containing a filtering higher plants. Among the practical consequences of this method – the prevention of water flowering that is especially useful for in-city reservoirs. The paper presented is devoted to investigation of a stepped mesh structure of this type that holds a plantings of water hyacinth. The macromorphological characteristics of the colonies attached to the assessment of nitrogen-transforming biocenosis according to the total index of species diversity were studied. The results show that the redox capacity reserves of phytostructure biomodules are more than 40% while the nitrification efficiency is about 90%. In addition to plant adsorption effect the increased formation of activated sludge takes place. The concept allows to start an effective exploitation immediately after the placement and leads to significant financial economy after the first year of using. In general, the approach presented is easily adaptable and can be used for most of the existing in-city water reservoirs.

“…A number of studies have been devoted to the design of devices for biological wastewater treatment with the creation of anaerobic conditions for the most efficient removal of organic matter at high load, while reducing the amount of air and significantly reducing the amount of sediment formed [5][6][7][8][9][10][11][12]. Most of the works are devoted to the development of multi-stage wastewater treatment systems, where biological treatment is included in the composition [13][14][15][16][17][18][19][20].…”

Biological activity of sludge systems at microscale level is extensively used for effective wastewater treatment. The creation of nature-like artificial ecosystems with a large species diversity is a key point for biocenosis adjusting ability in the municipal wastewater treatment structures. The aim of the study presented is to model at the laboratory scale and to study a stability of active sludge mixed biocenosis physiological state during its aging. The measurements performed using the flow model of aeration tank-mixer with built-in sump.
