- ДокументAir-liquid microtube carbon dioxide capture system(2022) Popivchak, B.; Koval, S.Our approach lies in using an already effective and performant mechanism of the human respiratory system repurposed to filter and transform carbon dioxide instead of oxygen. This concept effectively divides posed problem into three separate tasks: capturing of CO2 (taking analogy from alveoli to increase contact area), transportation of CO2 through-out the system (optimized substance analogous to blood to provide minimum losses of gas), and utilization system (inspired by cells functionality we combine CO2 with industrial waste to produce carbonates). What is unique in our approach is the choice of materials and substances that enable us to create efficient and performant system.
- ДокументWastewater treatment by biological methods(2022) Iliv, V.; Donald, Ch.Purpose of the work is to analyze existing wetland systems, biotechnologies on using hydrobionts and aerated lagoons in wastewater treatment systems. Task of the work is to elaborate experimental wastewater plant unites based on its function characteristics for suggesting improved models. Relevancy of the work is the increasing environmental pollution caused by wastewaters and urgent need for improved implemented wastewater treatment systems. Study methods used in the work included general scientific methods as system analysis, induction, deduction. Obtained results of experimental studied concluded the following: the efficiency of different pollutants removal is higher in hybrid constructed wetlands than in one-stage systems; hybrid constructed wetlands not only resolve ecological problems about wastewater management but can also provide landscape and educational profits because of their interesting shapes and innovative methods used; long term research on the operation of constructed wetland systems in Poland indicate that these systems can be used with great success on rural areas, especially in protected areas and valuable landscapes in Ukraine; cyanobacteria biomass, released from cultural medium, can be used for production of small tonnage valuable products with unique properties, large tonnage biomass of natural origin can be used for fuel production (biomethane, bioethanol, biodiesel); suggested two-stage purification scheme of landfill infiltrates enables to purify infiltrates effectively with primary purification under conditions of aerobic lagoon on the territory of landfill, transporting of infiltrate with the help of pipeline «landfill – municipal PCF», dissolving it with municipal sewerage effluents and pretreatment on municipal PCF.
- ДокументThe impact of the combat on the environment: the experience of the world and Ukraine(2022) Bohach, N.; Labadze, N.Despite all the achievements of progress, war remains an important means of resolving the contradictions of mankind. Moreover, the growth of the world's population and the large-scale level of industrialization have led to the fact that since the last century, wars have begun to cause significant damage to the environment. Despite the efforts of environmental scientists, the issue of environmental protection is still not given enough attention, while the issue of environmental security in the armed conflict is becoming increasingly important. The purpose of this work is to comprehensively assess the impact of wars and armed conflicts on the environment, both globally and in the context of the war caused by Russia’s armed aggression against Ukraine. This work assessed the environmental impact of all modern wars and armed conflicts since the beginning of the XXI century, as well as a detailed analysis of the environmental aspects of the war that has been going on in the East of Ukraine since 2014 caused by Russia’s armed aggression against our state. The study also provides a predictive assessment of the further nature of changes in the impact of wars on the environment and provides recommendations on ways to minimize them, both in Ukraine and internationally.
- ДокументBiological treatment of leachate landfill filtrates(2022) Kononenko, P.; Krachunov, G.Actuality of the work. Existing landfills of Ukraine today turned into powerful sources of environmental danger. The problem is specifically hectic for Ukraine since there are many landfills from Municipal solid wastes (MSW) in Ukraine that have been in a need for closing for a long time already. Same problem exists in other countries. For solution of this problem it is suggested a two-stage purification for infiltrates on landfills in Ukraine and reduction of environmental danger from their accumulation (that is observed on the example of Hrybovytske landfill). Aim and tasks of the work. Aim of the work is to increase a level of environmental safety of hydrosphere with the help of two-stage purification of infiltrates from landfills in aerobic lagoons and municipal sewerage pollution control facilities (PCF). For achievement of the set aim the following tasks should be solved: -to conduct analysis of environmental danger sources of hydrosphere on the territory of Hrybovytske landfill; -to study process of biological purification of infiltrates in aerobic lagoon in static regime; -to set optimum conditions for biological purification of infiltrates in aerobic lagoon in dynamic regime; -to set technological peculiarities of implementing a stage of pretreatment of infiltrates on landfills in aerobic lagoon; -to set stability of parameters for tertiary treatment of infiltrates on municipal PCF; Scientific part of the work lays in: 1. Setting impact of parameters in implementation process (time of delay of infiltrates in aerobic lagoon, temperature, periodicity of it) on effectiveness of infiltrates` purification in aerobic lagoon that would give opportunity to optimize purification process. 2. Studied peculiarities of biocenosis development of aerobic lagoon that enabled to prognosticate a development of biological process of infiltrates` purification. Result of the work is: setting optimum conditions for implementation of two-stage technology of landfills infiltrates purification.
