HAZARDOUS DISCHARGE IMPACT ON THE ENVIRONMENT OF AMUR REGION

The Amur region’s environmental conditions have been characterized as satisfactory over the past few decades due to a decrease in the perceived risk associated with historical and current economic activities. In fact, the local population is under tremendous threat as a result of the tense and conflicting atmosphere. Both permanent stationary sources and diverse means of mobility emit a wide range of suspended particles with unknown compositions, as well as liquid and gaseous chemicals like benzo(a)pyrene, formaldehyde, and heavy metals into the atmosphere and surface water.

Bacterial soil pollution, forest fires, and the disposal of consumer and industrial waste have all had a negative impact on wild animal populations. Natural hazards in this region include catastrophic floods, forest fires, strong winds, ice, patchy permafrost, and more. The risks linked with anthropogenic activity in the region stem from the implementation of major development projects such as the Vostochny Cosmodrome, the Amur Nasochemical Complex, and the Amur Gas Processing Plant. During the Project’s commissioning stages, risks and consequences on public health and safety are principally linked with issues such as production facility operation, general noise and air pollutants. The impact of dredging in rivers is given special attention, and the places of the most potential petroleum product and chemical leaks are initially studied.

In this paper, we report the first findings of a new case study in which modern technologies are used to construct multi-stage cleaning processes, reducing water intake from the river and almost eliminating wastewater output, with excess water released only after heavy rainfall. Rainwater from non-production plant roofs is purified before reaching fisheries parameters. Using “dry” gradients in the cooling system of technical equipment reduces natural water intake, saving 14 million cubic meters of water per year. Additionally, efforts are underway to optimize waste levels by using low-waste production designs that meet international requirements. This includes using highly efficient catalysts to reduce by-product formation, absorbents and catalysts for raw material purification with regenerative capabilities, and repurposing production by-products as secondary resources for heat and steam recovery, extending their service life by at least four years.
