摘要
污泥作为建筑材料原料既能为城市建设提供建材,又能减少城市污泥污染。污泥作为建材原料需解决重金属高温挥发以及有机污染物形成的关键技术问题,利用重金属稳定技术以及水泥等建材生产过程中的高温条件(1 450℃),解决了重金属挥发和二恶英生成的问题,可实现污泥的无害化、资源化利用。
Wastewater sludge can be used as raw materials of building with economic and social benefits.But the key technical problems of the sludge to be used as raw materials of building should be solved,such as the heavy metal evaporation and the forming of organic pollutions.The heavy metal stabilization technology can be used to inhibit the evaporation,and the dioxin problem can be solved through the high temperature（1 450 ℃） in the cement rotary kiln.This method can make the sewage sludge harmless and so realize the resourceful utilization.
