Abstract
This paper gives a review of established and emerging technologies for the treatment of wastes and soils contaminated by Persistent Toxic Substances which include the Persistent Organic Pollutants. The technologies are classified as biological, physico-chemical, and thermal treatments, describing main unit operations and comparing technical, social and environmental limitations, including some potential risks and environmental impacts. Estimated overall costs, cleanup times, reliability, and maintenance levels are also presented in order to assess advantages and limitations of each technology.Ovaj članak donosi pregled postojećih i novonastajućih tehnologija obrade otpada i tla onečišćenog perzistentnim otrovnim tvarima uključujući i perzistentna organska onečišćivala (engl. persistent organic pollutants). Autor dijeli tehnologije obrade na biološke, fizikalno-kemijske i termalne te opisuje rad osnovnih uređaja i uspoređuje tehnička, društvena i ekološka ograničenja, uključujući moguće rizike i učinke na okoliš. Članak također razmatra ukupne procijenjene troškove, vrijeme potrebno za čišćenje te razine odgovornosti i održavanja dajući na uvid prednosti i ograničenja svake tehnologije zasebno
