Abstract
Sludge thickening contains gravity thickening,air flotation thickening and mechanical thickening.At present,mechanical thickening is the main process in China's municipal wastewater treatment plant.The development trend of sludge thickening is to gradually replace the gravity concentration with air flotation thickening and mechanical thickening,improve integrated equipment for sludge thickening and sludge dewatering,and develop low concentration sludge thickening process.
