Tiivistelmä
Mining industry has a great impact on the environment including aquatic systems. Therefore, efficient water treatment is an important factor for sustainable development of every mining enterprise.
The study was done for the Finnish company Measurepolis Development Ltd. with the main aim to examine the current situation of water treatment and environmental impacts in Russian mining industry. The identification of the present needs and problems may help Measurepolis Development Ltd. to enter the Russian mining market with proper solutions and perspective technologies.
The Russian legislation controlling the environmental aspects of any activity is described. It includes the main procedure which must be conducted by every mining enterprise and a
number of permits which must be obtained by every company whose activity might have a negative impact on the environment. Moreover, there is information about changes in the permit system and transition to the complex environmental permit.
The theoretical part contains the description of standard waste water treatment methods that are used in Russian mining such as mechanical, physicochemical and biological.
The research concerns five mining plants located in the South and Central parts of the Russian Federation. Description of water treatment facilities and methods which are used by these mining companies is provided. The assessments of water quality of the water bodies located close to the mining sites and that might be affected by waste water discharge or in any other ways were also performed.
As a result of this study, a negative impact of the mining plant on the environment is identified. The amount of contaminants in waters does not conform to the official
requirements and exceeds the threshold limit values. Water treatment facilities and methods applied do not generally treat waters sufficiently because of their old conditions.
