摘要
垃圾焚化底渣係指垃圾焚化廠以焚燒方式處理都市固體廢棄物(Municipal Solid Waste, MSW)後所殘餘之灰渣,又稱焚化底渣。底渣具有比重輕、吸水率高、具有多種重金屬(如如銅、鉛、鉻、鎘、鋅等)、高鹼性、高氯離子含量等特性。
有鑑於國外對於底渣資源再利用之技術已成熟且已有諸多地工方面之實務應用,本文主要彙整國內近年來對於底渣再利用之相關研究成果,包括底渣取代天然材料應用於道路基底層與路堤回填料以及CLSM等應用。希望藉由本文之介紹,能有效利用底渣此種再生資源,進而減少天然資料之消耗,達到資源永續經營的目的。
英文摘要
Combustion bottom ash is a residue produced by the mean of incinerating municipal solid waste at trash incineration. The municipal waste bottom ash has several characteristics, such as light specific gravity, high absorptivity, heavy metal, including copper, lead, chromium, and zinc, etc., high basicity, and high concentration of chloride, and so on. In consideration of sophisticated technology of bottom ash recycling and practical applications of geotechnical engineering in Taiwan, recent studies of bottom ash recycling are collected in this paper including that bottom ash replaces for natural materials in base layer of road and application of CLSM. Hopefully, due to this introduction of bottom ash recycling, a decrease in loss of natural materials and perpetual operation of natural resources could be achieved.
