摘　　要：污泥石灰稳定干化技术是近年来研究应用较多的一项城市污水污泥处理技术,该技术在方庄城市污水处理厂的成功应用实现了方庄污水处理厂污泥的减量化、稳定化和无害化。石灰稳定干化后,污泥含水率迅速降低到40%,污泥堆置8d后,含水率降低到5%;干化污泥有机物含量由45.58%降低到8.27%;堆置5d后,大肠杆菌和粪大肠杆菌未检出。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 successfully. 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. The organic material of sludge can decrease from 45.58 % to 8.27 % after sludge drying. Both coliform and fecal coliform are totally removed after 5 day＇s storage in the open air.
