Background: The development and implementation of new methods of environmental monitoring is an urgent problem due to the technogenic pollution of the Earth's biosphere. The remote control of the gas composition of the surface atmosphere layer in industrial zones of modern metropolis is important for determining penalties for enterprises whose emissions of pollutants exceed established norms. Objectives: Development of an ecological Spontaneous Raman Scattering (SRS) lidar for monitoring the gas composition in the air basin of large megacities. Theoretical verification of the lidar effectiveness for problem solving. Materials and methods: The developed lidar for environmental monitoring of the atmospheric surface layer is based on the SRS method which allows remote monitoring of the atmospheric gas composition at distances up to several kilometers with a fairly high resolution (up to 1 meter). The absolute concentration of detected polluting gases is determined by comparing the intensities of the satellite pollutant and nitrogen lines in the recorded SRS spectra. Results: The choice of the SRS method for remote laser monitoring of the atmosphere ground layer in large industrial centers is substantiated. The block diagram and the main technical characteristics of the developed SRS lidar are presented. Preliminary estimates of the lidar efficiency for the environmental monitoring were carried out. Conclusions: The simulation results have shown that the specifications of the SRS lidar allow detecting of following polluting gases: CO, NO2, SO2, CH4, H2S, C6H6 at distances up to 200 m with the maximum permissible concentration level. The simulation results were obtained when accumulation time varied from 10 s to 4 min. The specification of the SRS lidar allow its using for remote monitoring of air conditions in the cities and near industrial enterprises.

In Ukraine, the condition of surface water near industrial enterprises is extremely critical. The operation of enterprises leads to intensive water pollution with industrial and domestic wastewater. Therefore, improving the quality of treatment facilities through the introduction of automated control systems is an urgent problem. For the operation of automated control systems for typical cleaning processes, a software package is required, which is developed on the basis of appropriate algorithmic software and mathematical models of processes. To obtain them, methods of mathematical and simulation modeling and block diagram method of algorithmization were used. In order to assess the quality of the developed algorithm for controlling the process of buffer wastewater neutralization during operation, a comparison of control system operation based on this algorithm with the most successful foreign variants of neutralization control systems was made. Simulation for the average values of operating parameters Q = 75 m3 / h, CP = 75 g / l, and Ck = 2 g / l at minimum b = 0.02 g / l pH and maximum buffer value b = 0.47 g / l pH, and also with  unidirectional extreme combination of parameters Q = 50 m3 / h, CP = 100 g / l, b = 0,02 g / l pH and Q = 100 m3 / h, CP= 50 g / l, for minimum b = 0.02 g / l pH and maximum buffering value  b = 0.47 g / l pH shows that the best quality of transient processes is for the control system operating on the basis of the developed algorithm. For any combination of parameters, the transients for this control system provide better quality transients. Studies have shown that the control system based on the developed algorithm in comparison with the previously proposed systems provides better process control by reducing the time of transients and reducing the dynamic deviation of the output parameters, which improves the quality of wastewater treatment. Given the non-stationary process and high requirements for the cleaning parameters, manual control of this process is beyond the power of even an experienced operator. The developed mathematical model describing the dynamics of the wastewater neutralization reactor with buffer properties and the process control algorithm made it possible to proceed to the development of the control system software, which is necessary for the automated control of this process.

The Impact

The Arctic zone of the Russian Federation (AZRF) is characterized by the fragility of the ecosystem, the slightest violation of which can lead to catastrophic negative consequences on a global scale. Due to the availability of production facilities of various scales and environmental safety classes within the territorial and aquatic Arctic, the risk of negative impact on the environment is very significant. In order to prevent possible environmental damage within the AZRF, it is advisable to carry out activities related to the implementation of continuous monitoring of the environment aimed at detecting sources that pose a potential threat to the ecosystem. Taking into account the harsh Arctic climate, the lack of the possibility of year-round land access to industrial facilities located in the Russian Arctic, the scale and peculiarities of the implementation of Arctic offshore projects for the extraction and processing of hydrocarbons, the length and congestion of the used logistic artery - the Northern Sea Route, the choice of means, which are used for monitoring the ecological situation is justified by their mobility and efficiency. In particular, such means include technologies that allow remote monitoring of the environmental situation of industrial facilities. The article outlines the role of remote methods of environmental monitoring and control in the system of environmental protection measures of the Russian Arctic, presents methods for assessing the impact of industrial facilities of the oil and gas complex (OGC) on the environment of the Russian Arctic, presents the results of assessing the effectiveness of using remote methods of environmental monitoring of industrial facilities for the production and processing of hydrocarbons (HC) in the AZRF. The scientific novelty of the study lies in the substantiation of the ecological and economic feasibility of using the methods of remote monitoring of the ecological situation in the Arctic.

The Relationship

Condenser water from the discharge channel PJB Paiton discharged to the sea has the potential mechanical energy, because the flow rate of 7.6 m3 / s (if both discharge PJB Paiton function) and the discharge channel reaches a height of 4m. This paper will describe the design of hydro power (in the form of a block diagram) by using Kaplan turbine driven by utilizing the wastewater condenser. Kaplan turbine performance represented in the form of the relationship between the incoming water flow and the pitch angle (the angle between the propellers with a hub) to the torque generated. The simulation results indicate that the turbine torque is proportional to the mechanical power turbine. The greater the torque, the greater the mechanical power, and vice versa.

At present much attention is paid to the investigation of the indicative features of organisms on the whole and vegetative objects in particular. However, it should be noted that sources of toxic elements distributed unevenly on the territories and having various character and intensity in the form of the enterprises and constructions create rather motley picture of environmental pollution both by structure of pollutants, and by their concentration. Therefore an important scientific problem is the examination not only of changes in conditions of technogenic influence in general, but the research of dependence of intensity of morphological plants parameters change on structure and concentration of chemical pollutants in the environment, and also the assessment of possible consequences of pollutants accumulation in vegetative objects. This was the aim of this work. To perform the work used landscape-geochemical analysis include, extending the definition of the emission factor load, characteristic technogene sources of pollution in the form of industrial plants, evaluation of storage medium (vegetation). Vegetation condition was assessed by determining morphological parameters - the length and width of the leaf blade. The article presents a comparative assessment of the anthropogenic impact level of the largest industrial enterprises on the air state in the city of Gomel. Enterprises of western and southern industrial zone have proved to make the greatest contribution to the urban air pollution. The value of the standard deviation was used to assess the degree of anthropogenic impact of industrial enterprises on morphological parameters of woody plants. This index increased in the western and southern industrial zones in the direction from the enterprises with the large volume of pollutant emissions to the enterprises with the small volume of emissions. This trend is caused by stabilizing selection action due to the environmental stress in the form of emissions of the industrial enterprises in these zones. It is also revealed that in western and southern industrial zones the formation of the leaf blade length and width depends more on the level of anthropogenic impact of the chemical plant, combined heat and power plant, JSC «Centrolit» and JSC «Gomeldrev» compared with other companies, that should be considered when further improvement of environmental activities. The results are generally characterized by scientific novelty of the research and can be used for the purpose of indexing the level of anthropogenic impact on urban areas and further improve the methods of monitoring the state of the urban environment. Next it is planned to evaluate the morphological parameters of the leaf blade of woody plants growing in the area of two large industrial enterprises of the Gomel region – JSC «Mozyr Oil Refinery» (Mozyr), JSC «Belarusian Metallurgical Plant» (Zhlobin) and in city parklands. Then the further testing of the heavy metals content will be carried out in the samples of woody plants, grasses and soil from the territory of the industrial enterprises and parklands of the city of Gomel, Mozyr, and Zhlobin.
