The Application of conserved emissions of sulphurous gases for improvement of alkaline soils

Abstract

The aim of the study is to provide integrated solution of environmental problems by help of conservation emissions of sulphurous gases in form of sulphur or treated cement dust and their application for improvement of Alkaline Soils. New ameliorants for improvements of Alkaline soils under laboratory conditions were obtained: electro-treated mixture of sulphurous and sulphuric acids, treated cement dust containing sulphite and sulphate salts of Ca. Two electrochemical methods for production of sulphuric acid and mixture of sulphuric and hydrochloric acids from sulphurous acid were developed and the electric energy requirement for their production is calculated. The process of retention of sulphurous gases, by water solution of cement dust is studied. It is shown, that for conservation of 1 t of sulphurous gases 2 t of cement dust is required. The influence of newly-received ameliorants on physical and chemical properties of Alkaline soils during their chemical reclamation and leaching processes was studied. The most ameliorative effect, obtained in the variant, where electrochemical treated solution of the mixture of sulphurous and sulphuric acids were used.
