Treatment of leachate from a domestic solid waste sanitary landfill by an electrolysis system.
This study deals with the characteristisation and the treatability of leachates from the new municipal domestic waste (DW) landfill site in Athens, Greece, using an electrolysis system. This site has been in operation since July 1998. The leachate from this site has mean COD and BOD5 values of 53300 and 30300 mg l(-1), respectively, and constitutes a major environmental problem that must be taken into serious consideration. An electrolysis system, using Ti/Pt electrode in alkaline conditions was used to treat the leachate. The study showed, that the COD was reduced by 84%, and that VSS, N-NH4 and Total Phosphorus were reduced by 100% within one hour of electolysis and at pH 9. The efficiency of electrolysis went up to 32 g COD removed (CODr)/h-A-m2 and the energy consumption was 12.6 kWh kg(-1)CODr.
