Expluatation of enrichment operating stages with sodium cyanide, leads to toxic waste production in large volumes: wastewaters, gas emissions, solid cyanidation waste. As a result of incorrect environmental management on gold recovery plants, this negative impact leads to propagation of toxic pollutant substances. It could be the reason of nature widescale degradation in the gold factories affected area. In turn, the environment protection measures realesation needs to accounting of the contaminants properties and their migration conditions in the natural environment.
Any industrial agglomeration is a territory, not only with a high concentration of industrial facilities, but also with high population density. This, in turn, is an essential prerequisite to problems associated with the large volume of waste consumption. To solve these problems it is necessary not only to improve the technology for processing different kinds of waste, but also to establish a system by their rapid collection and transport.
The increase in household waste in St. Petersburg and Leningrad region inevitably leads to environmental degradation, but, unfortunately, the political priorities in the field of waste management are far from perfect and the prevailing non-interference policy leads to economic inefficiency of waste management.
At the current rate of urban growth, increasing amounts of municipal waste. The process of collecting and transporting the waste to organize specialized transport companies. In modern conditions it is necessary to modernize the process, which requires the use of advanced information technologies. Creating a management information system capable of increase the efficiency of transport companies, will help solve the problem of municipal waste, and, consequently, to improve sanitary and environmental conditions in cities.
Joint Stock Company «Apatit» is the world’s largest producer of phosphate raw materials for the production of mineral fertilizers. The processing of ore and obtaining of apatite and nepheline concentrates are carried out at the ore treatment factory ANOF-2. Nowadays there is an acute problem of additional wastewater treatment in concert with the presence of nitrites, fluorides, phosphates, aluminum and molybdenum in flows the concentrations of which exceed the established standards. Using the fine cleaning filters, the filter material of which is made of synthetic fibers, the quantity of waste substances dropped into the water can be reduced. The using of such filter system will allow decreasing the damage to the environment and reducing the enterprise payouts for the discharge of pollutants.
The work is devoted to the study of physicochemical parameters of urban sewage sludge and establishment of technical principles of utilization of industrial volumes of urban sewage sludge.
This work is focused on creating a technological option for joint processing of BOF, blast furnace and open-hearth dusts with subsequent involvement of semi-products in the main production of Severstal and similar enterprises.
