ABSTRACT
The main ways of disposal of sewage sludge in the European Union and Ukraine are considered. The main problems of sludge utilization in Ukraine are identified. Research has been conducted on the possibility of using a substrate based on sewage sludge for biological reclamation of disturbed lands. Determined the quality of the sludge from Lviv WWTP. The best substrate composition for biological land reclamation is determined by using bioindication. It is established that the use of settled sludge observed inhibition of plant growth and development. Adding additional components to the substrate, in the form of sorbents, makes it possible to increase the content of sewage sludge. Positive changes in plant growth and development have been observed when using a soil-based substrate, sewage sludge and sorbent.
