基于精准处置的施工和装修废弃物分类分选技术研究

大规模的城市开发建设及快速的城市更新产生了大量的施工和装修废弃物。有限的消纳场容量满足不了目前以填埋为主的处置需求，施工和装修废弃物的排放和处置出现困难，亟须加强其回收与再利用。精准的分类分选是施工和装修废弃物综合利用的关键技术，而其成分复杂性及有毒有害特性对分选提出更高的要求。为此，梳理施工和装修废弃物的处置现状，基于成分及产量特性分析施工和装修废弃物的分类处置需求，提出基于精准处置的施工和装修废弃物分选技术流程，为施工和装修废弃物精准分选提供参考和借鉴，促进施工和装修废弃物的资源化利用。

Research on Classification and Sorting Technology of Engineering and Decoration Waste Based on Precision Disposal

Massive urban construction and rapid urban renewal generate large amounts of engineering and decoration waste. Limited accommodation capacity cannot meet the current landfill-based disposal needs. The emission and disposal of engineering and decoration waste are complicated, and it is urgent to strengthen its recycling and reuse. Accurate sorting is the critical technology of comprehensive utilization of engineering and decoration waste, and its composition complexity and harmful characteristics propose higher requirements for sorting. Therefore,?the disposal status of engineering and decoration waste is studied . The classification and disposal requirements of engineering and decoration waste are analyzed based on composition and characteristics. The technical process of engineering and decoration waste sorting based on precision disposal is proposed, which provides a reference for the precise sorting of engineering and decoration waste. The resource utilization is promoted of engineering and decoration waste.
