Features of the water treatment technology of fish breeding plants in the southern region of the Russian Federation using agricultural waste

Abstract

One of the main reasons for the decline in fish numbers is the insufficient quality of water used in hatcheries. The degree of purification of recycled water does not meet the requirements for water in pools. Thus, in order to reduce pollution concentrations, it is necessary to develop new technologies for the treatment of recycled water from fish farming plants, including through the integration of a lighting and aeration plant into them, as well as a sorption unit using agricultural waste, namely rice straw

Influence of Mechanochemical Activation of Concrete Components on the Properties of Vibro-Centrifugated Heavy Concrete

“…To determine the role of our research in the system of new knowledge in the field of construction, it is necessary to explain and interpret the results of our research by comparing them with the results of previous research by other authors [11,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]33].…”

“…There Studying the phenomenon of activation, the authors considered the technology of vibration in previous works [11,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]33]. Concrete, as an object of research, was studied by varying composition and technological factors during manufacture.…”

“…At the same time, it should be noted that in the works [11,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]33], the investigations were devoted to studying the influence of one type of activation effect on the properties of concrete.…”

“…The comprehensive effect of double activation, that is, the chemical and mechanical of two different components, that is, the mixing agent and the binder, is investigated in this article. Thus, the synergistic effect is achieved because the optimal processing of such Studying the phenomenon of activation, the authors considered the technology of vibration in previous works [11,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]33]. Concrete, as an object of research, was studied by varying composition and technological factors during manufacture.…”

“…The water was activated by purifying it, which consisted in filtering through a sorbent-activated biochar from the waste of the agro-industrial complex-rice straw. The technology for obtaining activated water was followed in strict accordance with the methodology [33].…”
