Sludge heat treatment after treatment of drainage wastewater from municipal solid waste landfills

The process of calcium oxide regeneration from the sludge left after treating landfill drainage wastewater was studied. It was found that calcium oxide can be regenerated from sludge by means of heat treatment in electric furnaces within three hours at 700°C and 1.5 kW power consumption per 1 kg of...

Zusammenfassung:	The process of calcium oxide regeneration from the sludge left after treating landfill drainage wastewater was studied. It was found that calcium oxide can be regenerated from sludge by means of heat treatment in electric furnaces within three hours at 700°C and 1.5 kW power consumption per 1 kg of sludge. It was shown that calcium oxide regenerated from sludge was not inferior in quality to commercial one and may be reused in technological process.
