Abstract The technology of sludge lime drying is researched and applied widely. It is used as the sludge treatment process in Fang
Zhuang Wastewater Treatment Plant essfully. The advantage of Lime Drying Process is that it makes the sludge meet the
requirement. The moisture content of sludge can decrease to 40 % after sludge drying, then decrease to 5 % after 8 day ’s storage in
the open air. anic material of sludge can decrease from % to % after sludge drying. Both coliform and fecal
coliform are totally rem
