Development of the beneficial utilisation of urban sewage sludge using modern analysis methods

Abstract

Abstract The article presents Russian and foreign experience in the recycling of sludge of urban sewage wastewater with the prospect of the beneficial use of both the direct waste and the products of its processing. Special attention is also paid to the problem of recycling of ashes of sewage sludge incineration. The article also considers the possibility of applying modern methods of analysis (such as X-ray fluorescence analysis, spectroscopy, biotesting) to develop a composition of the ash-based soil mixture. The study is realized on the laboratory and experimental base of the accredited Center for the collective use of high-tech equipment of Saint-Petersburg Mining University (as a part of state task for 2018-2019 year).
