TREATMENT METHOD ON REUSING OF CONSTRUCTION WASTE FOR ACQUIRING OF HIGH QUALITY RECYCLING AGGREGATE AND COMBUSTIBLE MATERIAL

摘要

PURPOSE: An environmentally-friendly construction waste recycling method is provided to treat one or more of dust containing air, washing water, and sludge from construction waste treatment processes using various materials containing carbon dioxide. CONSTITUTION: An environmentally-friendly construction waste recycling method includes the following: one or more materials of dust containing air(6), washing water(7), and sludge(8) are treated using various materials containing carbon dioxide. A plurality of reactions is implemented. Recycled aggregate, combustible materials, and recycling materials of high quality are obtained. The alkalinity and the heavy metal contents of the recycled aggregate, the combustible materials, and the recycling materials are reduced.
