| 摘要： | Currently, wastewater sludge for the U.S. Forces, Korea (USFK) and the Eighth U.S. Army (EUSA) is disposed at landfills by Korean contractors. In the United States, CFR 40, Part 503 regulations encourage the beneficial use of biosolids. However, beneficial use of sludge is not practiced in Korea. This report discusses the different regulatory frameworks in the United States and Korea, the current status of USEK/EUSA sludge management at four Directorates of Public Works (DPWs) and improved sludge management systems. Technical alternatives for improving sludge management include mobile mechanical dewatering, alkaline stabilization, composting, reed bed use, and autothermal thermophilic aerobic digestion (ATAD). Technologies were chosen for review based on their ability to comply with both U.S. and Korean regulations and to achieve long-term improvement, and their availability in Korea. The study recommended: (1) Use of mobile mechanical dewatering followed by either aerated static pile composting, windrow composting or alkaline stabilization for the Western Corridor DPW (2) Discontinuation of the current secondary treatment at the Yongsan DPW (3) Conversion of the Camp Humphreys' current sand-drying beds to reed beds (4) Establishment of a long term goal to convert Camp Casey's aerobic digester to ATAD and using the biosolids as a soil supplement at Camp Casey. |
