The use of bioindication to determine the possibility of sludge recovery after biological treatment of wastewater / Oksana Shkvirko, Ivan Tymchuk, Myroslav Malovanyy // Environmental problems. — Lviv : Lviv Politechnic Publishing House, 2018. — Vol 3. — No 4. — P. 258–264.https://ena.lpnu.ua/handle/ntb/46005These 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.258-264ensewage sludgesubstrateLMWWTPsbioindicationspent active sludgeArticle© Національний університет “Львівська політехніка”, 2018© Shkvirko O., Tymchuk I., Malovanyy M., 20187Shkvirko O.
