Item Obtaining and Using Substrates with Sewage Sludge(Видавництво Львівської політехніки, 2022-03-01) Malovanyy, Myroslav; Storoshchuk, Uliana; Lviv Polytechnic National UniversityThe article is devoted to the study of the prospects of using compost with sewage sludge in the raw material for the recultivation of disturbed lands. A special installation was used for bio-composting, which allowed controlling of the process parameters. The results of bio-indication of composts obtained under different conditions of compositions of the raw material mixture are given. Based on the analysis of the results of bioindication, the optimal composition of the raw material mixture using “fresh” and “old” sewage sludge is established. An analysis of the parameters of the bio-indication process was carried out for this compost of optimal composition, which makes it possible to develop recommendations for the implementation of the process in industrial conditions.Item The use of bioindication to determine the possibility of sludge recovery after biological treatment of wastewater(Lviv Politechnic Publishing House, 2018-02-26) Shkvirko, Oksana; Tymchuk, Ivan; Malovanyy, Myroslav; Lviv Polytechnic National UniversityThese studies were conducted to test the hypothesis that sewage sludge from Lviv municipal wastewater treatment plants (LMWWTP) facilities can be used to create a substrate that can be used for biological reclamation. The qualitative composition of sewage sludge from Lviv municipal wastewater treatment plants is determined. The study of bioindication of a mixture of sludge with dark gray soil was carried out in two stages, which showed a significant difference between fresh and settled sludge. Possible conditions for the use of sludge in the substrate are presented.
