【 摘 要 】

The article deals with the project and implementation of ecological engineering technological measures in practice. As a result, the impact of sub-sludge waters, flooding and pollution of the surrounding area to the sludge storage of alumina plant decreased. Commissioning of a new sludge map with waterproofing screen has reduced the pollution of groundwater and surface water sources. The construction of an interception system of filtration water around the sludge storage reduced the groundwater level by more than 1m and provided conditions for the restoration of disturbed lands. Technological solutions for the restoration of disturbed lands using substrates made of non-toxic technogenic materials have been developed. It was found that the use of a neutralizer (ammonium sulfate) and sludge from treatment facilities as the main component of the soil substrate leads to a change in the pH value from 9.8 to 7.5 pH. In this case, there was a transition from the strongly alkaline reaction to almost neutral. The use of natural and technogenic sources for recultivation will ensure the creation of an artificial agroecosystem in the area of the existing industrial enterprise and reduce the anthropogenic impact of production on biota.
