KEYWORDS
ABSTRACT
In the mining area of Sardinia, many years after the end of industrial activity, a lot of tailing basins result as abandoned and constitute dangerous sources of contamination for groundwater and soils. Aimed at avoiding the diffusion of contaminants, electroosmotic technique can be used to realise low permeability barriers both at the basin bottom and along its perimeter. The paper describes the experimental activity carried out for evaluating the effectiveness of the electroosmotic technique and its applicability to a specific case of tailing dam remediation.

Zapewnienie nieprzepuszczalności niecek odpadowych techniką elektroosmozy
zapora odpadowa, elektroosmoza, wyciek, przepuszczalność
Na górniczych terenach Sardynii, wiele lat po zakończeniu działalności technologicznej, powstało wiele niecek odpadowych, które stanowią niebezpieczne źródła skażenia wód gruntowych i gleb. Aby nie dopuścić do dyfuzji substancji skażających, zastosować można technikę elektroosmozy do tworzenia barier niskiej przepuszczalności na dnie niecek i wzdłuż ich obwodu. Opracowanie opisuje eksperymenty prowadzone dla oceny efektywności techniki elektroosmozy i możliwość jej zastosowania w konkretnym przypadku zapobiegania przez powstanie zapory odpadowej.
