Actual ecologically friendly solving of problem of municipal sludge / Kira Kalinichenko, Galina Nikovskaya, Zoya Ulberg // Litteris et Artibus : proceedings of the 6th International youth science forum, November 24–26, 2016, Lviv, Ukraine / Lviv Polytechnic National University. – Lviv : Lviv Polytechnic Publishing House, 2016. – P. 494–497. – Bibliography: 15 titles.https://ena.lpnu.ua/handle/ntb/41167A new eco-friendly process for rational utilization of toxic municipal sludge wastes by their transformation into fertilizer for land application has been developed. It includes promotion of alkaline vector of heterotrophic microbial metabolism in high stable biocolloidal sludge system by adding special nutrients, heavy metals leaching and sludge suspension separating under the action of microbial metabolites. Each of the phases (sediment and bioextract) can serve as a fertilizer after procedure of additional stabilization. The fertilizers obtained satisfy the EU limits for the materials of agricultural utilization. The vegetation experiments have shown that the fertilizer application results in tenfold increase of plant harvest and provides high quality of target product.ensludge solidssewage sludgesutilizationagriculturalbioleachingheavy metalsConference Abstract494-497
