Ecological engineering in the process of gas treatment from dust and prospects for its use in agriculture

In this paper it is shown that the implementation of technological measures of ecological engineering in the sintering technology of alumina production allows reducing emissions of polluted gases into the atmosphere. The conducted industrial testing of the additional stage of wet gas treatment on sintering furnaces confirmed its high efficiency of gas treatment from fine-disperse dust. Physical chemical and morphological dust properties of gas treatment facilities of alumina production are investigated. The characteristic of the chemical dust composition of various technological equipment of gas treatment is given. The dust application of electrofilters in the alumina production as ameliorants for deoxidation of gray forest soils of the Western districts of the Krasnoyarsk territory. This will improve soil fertility and crop productivity through the absorption of soil cations calcium-containing waste and the sustainable functioning of the agrocenosis. (paper)
