Experimental simulation of a system of swamp biogeocenoses to improve the efficiency of quarry water treatment

Article preview

Mining activities were producing large quantities of wastewater contaminated with nitrogen compounds and metals. With insufficient treatment, these pollutants are released into the environment and have a toxic effect on living organisms. Constructed wetlands are now widely adopted as wastewater treatment systems because of the combination of physical, chemical and biological processes for the removal of contaminants. In this study, an experimental system was modeled to improve the efficiency of the quarry wastewater treatment of a mining enterprise by sharing the higher aquatic vegetation: broad-leaved cattail (Typha latifolia L.), common water-plantain (Alisma plantago-aquatica L.), jointed rush (Juncus articulatus L.) and lower aquatic vegetation (Chlorella sp.). Concentrations of nitrogen compounds and metal were analyzed both in the model and in the treated solution of quarry wastewater for calculation of treatment efficiency. Concentrations of the pollutants in the tissues of the higher aquatic vegetation were analyzed to assess the accumulation capacity and efficiency of translocation of the pollutants. The results of the experimental study showed the practical applicability of the constructed integrated treatment system to reduce the concentration of pollutants in quarry wastewater, as well as increasing the efficiency of treatment by introducing lower aquatic vegetation into the system

Ecological security and sustainability

Article preview

In 2015, UN Member States adopted the 2030 Agenda for Sustainable Development, aimed at balancing initiatives by the world community and individual countries in the environmental, social, and economic spheres. The global sustainable development goals are to promote the well-being of the world population, preserve the planet’s resources, and maintain ecological security, which is vital in the age of the rapid industrial growth and ever-increasing anthropogenic pressure on the environment. For the successful achievement of sustainability goals in the manufacturing sector, integrated measures should be undertaken for monitoring and assessing the technogenic impact of industrial facilities. Additionally, it is necessary to develop environmentally-friendly technologies in the fields of gas and water treatment, land reclamation, and waste disposal. Therefore, fundamental and applied research in these related spheres is of particular importance. Currently, environmental monitoring of all components of the environment, along with anthropogenic objects and processes, receives considerable attention, which is determined by the vector of development in science and technology. In this regard, the latest innovations in green technology in this area are becoming increasingly significant.

Environmental damage from the storage of sulfide ore tailings

Article preview

The mining industry is one of the most challenging in ensuring environmental safety. During the last century, the Karabash Copper Smelting Plant was processing sulfide ores and depositing the tailings into storage facilities that now occupy an area of more than 50 hectares. To date, abandoned tailings are a significant source of natural water, air, and soil pollution in the Karabash city district. The article comprehensively examines the environmental impact of the Karabashmed copper smelter, one of the oldest metallurgical enterprises in Russia. The effects of seepage from the two Karabashmed tailings facilities on water resources were assessed. We revealed that even outside the area of the direct impact of processing waste, the pH of natural water decreases to values 4-5. Further downstream, the infiltration water from the tailings pond No. 4 reduces the pH of river water to 3.0-3.5. The presented results of environmental engineering surveys are derived from sampling water and bottom sediments of the Ryzhiy Stream and the Sak-Elga River, sample preparation, and quantitative chemical analysis. The study revealed significant exceedances of the maximum permissible concentrations for a number of chemical elements in the impact zone of the copper ore processing tailings.

Methodology for thermal desorption treatment of local soil pollution by oil products at the facilities of the mineral resource industry

Article preview

The analysis of the main environmental consequences of leaks and local spills of petroleum products at the enterprises of the mineral resource complex is presented. It is established that the problem of soil contamination with petroleum products at the facilities of the mineral resource complex and enterprises of other industries is caused by significant volumes of consumption of the main types of oil products. Based on the results of the author's previous field research, a series of experiments was carried out, consisting in modeling artificial soil pollution with petroleum products such as gasoline, diesel fuel, highly refined oil, motor oil, and transmission oil, followed by their purification by heat treatment at temperatures of 150, 200, and 250 °C. The 250 °C limit of the heating temperature was set due to the need to partially preserve the structure and quality of the soil after heat treatment to preserve its fertility. When the processing temperature rises to 450 °C, all humates are completely burned out and, as a result, productivity is lost. Confirmation is provided by the results of experiments to determine the humus content in uncontaminated soil and soil treated at different temperatures. It was found that at a maximum processing temperature of 250 °C, about 50 % of the initial organic carbon content is preserved. According to the results of the conducted experimental studies, the dependences of the required processing temperature on the concentration of petroleum products to reduce the concentration of petroleum products to an acceptable level have been established. The methodology of thermal desorption cleaning of soils with varying degrees of contamination at enterprises of the mineral resource complex is presented.

Biogeochemical assessment of soils and plants in industrial, residential and recreational areas of Saint Petersburg

Article preview

Soils and plants of Saint Petersburg are under the constant technogenic stress caused by human activity in industrial, residential, and recreational landscapes of the city. To assess the transformed landscapes of various functional zones, we studied utility, housing, and park districts with a total area of over 7,000 hectares in the southern part of the city during the summer seasons of 2016-2018. Throughout the fieldwork period, 796 individual pairs of soil and plant samples were collected. A complex of consequent laboratory studies performed in an accredited laboratory allowed the characterization of key biogeochemical patterns of urban regolith specimens and herbage samples of various grasses. Chemical analyses provided information on the concentrations of polluting metals in soils and plants of different land use zones. Data interpretation and calculation of element accumulation factors revealed areas with the most unfavorable environmental conditions. We believe that a high pollution level in southern city districts has led to a significant degree of physical, chemical, and biological degradation of the soil and vegetation cover. As of today, approximately 10 % of the Technosols in the study area have completely lost the ability to biological self-revitalization, which results in ecosystem malfunction and the urgent need for land remediation.

LIGNIN SLUDGE APPLICATION FOR FOREST LAND RECLAMATION: FEASIBILITY ASSESSMENT

Article preview

The article analyses waste generation of pulp and paper industry in North-Western Russia. The environmental impact of waste storage facilities of the pulp and paper mill was assessed, the need for utilization of lignin sludge was justified. In North-Western Russia, 1.21 million hectares of disturbed areas are in need for reclamation; they are abandoned quarries and lands alienated for pipeline and road construction. The suitability of lignin sludge for preparation of artificial fertile soils for reclamation purposes is estimated. For this purpose, experiments were carried out to create an artificial mixture with different ratios of lignin sludge and soil, to detect the maldevelopment of several plant species grown on various compositions of lignin sludge and soils. It was revealed that lignin sludge as an organic additive to soils is not toxic to vegetation and living organisms, allowing improving fertility of artificial soils.

Management of ecological and economic risk of negative impact of wastes of mining and metallurgical production

Article preview

Russian and foreign models of environmental safety management at various industrial facilities are analyzed. It is established that either individual or social risks of human mortality are taken as hazard indicators, or expert assessment of potential risks is carried out without quantitative economic evaluation. Technogenic arrays are classified by degree of ecological hazard on the basis of modeled results of total costs of environmentally safe waste disposal depending on the degree of their ecological hazard. For each class of arrays the optimal strategy of ecological safety management is developed.

Environmental monitoring of sulfide-containing technogenic massifs

Article preview

To date, the total amount of rock mass displaced on the planet exceeds 100 billion tons. The result of such impact is the formation of man-made massifs - geological structures, composed of rocks or sediments of anthropogenic genesis, which differ in their composition (chemical, granulometric, bacteriological) and properties (physical, mechanical, filtration, sorption, etc.) from the host rocks. Shapes and sizes of man-made massifs are determined mainly by technological processes. In areas of sulfide-containing technogenic massifs, due to waste in an oxidizing environment, the formation of acidic drainage water occurs, the processes of formation of which are complex and nonstationary, which greatly complicates the monitoring of the state of the massifs. Development and application of a new method of acid-alkaline balance, consisting in determining and comparing the acid potential and neutralization potential, formed by rock or waste, allows with high expressiveness and accuracy to monitor the situation in areas of sulfide-bearing man-made massifs, significantly reduces the time for laboratory research.

Assessment of the risk of acidic water formation in the impact areas of mining and metallurgical enterprises

Article preview

The technogenic load of enterprises of mining and mining and processing industries causing pollution of land and water resources and atmospheric air is assessed. Mining enterprises account for up to 80 percent of the volume of stockpiled wastes of all production complexes. Development of methods to assess the risk of impact of technogenic arrays on the environment is a very urgent problem, since it allows preventing or reducing the negative impact of technogenic arrays by targeted selection of the type and design of storage facilities for projected and existing enterprises, development of a set of measures to improve and rehabilitate disturbed lands. The analysis of landscape-geochemical situation formed under the influence of intensive technogenic load in the areas of waste storing was carried out, the processes of formation of halos and pollution flows were studied; the method of ecological hazard assessment of technogenic massifs was created, the method of economically expedient and safe storing of waste was developed.

Environmental monitoring of water and air migration of polluting components from the territory of sulfide-containing waste storage sites

Article preview

Mining and mining-processing enterprises are one of the most intensive sources of environmental pollution by solid wastes, which make up more than 90% of the volume of mined mineral raw materials. The result of such impact is the formation of technogenic massifs. Comparative analysis of the results of monitoring of technogenic massifs has allowed us to identify a number of regularities of their impact on the natural environment: The technogenic array is a lithochemical halo of pollution; The result of dust and gas emission from the surface of the anthropogenic massif is the formation of atmochemical and redeposited lithochemical pollution halos, pollution of vegetation and near-surface sediments; Temporary and permanent flows from the anthropogenic massif carry out and re-deposited rocks, which causes the formation of hydro- and lithochemical pollution flows; Infiltration of natural waters through technogenic sediments leads to the formation of hydrogeochemical halos and pollution flows.

Assessment of environmental hazard of technogenic massifs of mining and metallurgical production

Article preview

An assessment of the man-caused impact of mining and mineral processing enterprises on the soil and water reservoirs, the atmosphere and, as a consequence, an increase in the morbidity of the population is given. The greatest pollution and disturbance of the environment is associated with the storage sites of solid and liquid waste, which occupy more than 120 hectares in the Russian Federation. The problem of creating a classification of waste storage facilities, their thorough characterization and environmental risk assessment is very pressing. Solving this problem will help to prevent or reduce environmental impact of storage places by means of justified choice of type and design of waste storage for projectable enterprises and development of a package plan for environmental sanitation and reclamation of the territories under the impact. It will also help to cut down construction, operation and environmental expenses. Implementation of land reform requires strengthening state supervision of land and water use and conservation based on large-scale implementation of modern means of monitoring land and water conditions, as well as development of environmentally safe norms and requirements for land and water use. The results of the development and implementation of new methods of rapid assessment of the impact of solid waste on land and water reservoirs are presented. A new complete classification of technogenic tracts, based on the principle of their formation, their multivariate impact on the environment and methodological approach to the ecological and economic risk assessment of the impact of technogenic tracts on the environment is given.
