摘要:
建筑垃圾产生量的持续攀升给城市环境带来了严重危害，因而迫切需要寻求针对建筑垃圾回收处理并再生利用的解决途径。建筑垃圾再生骨料作为一种低成本、大体量的再生材料，在水处理领域具有一定的应用潜力。选取再生砖骨料（RBA）与再生混凝土骨料（RCA）应用于透水铺装，通过搭建5种系统，分析在不同进水浓度、降雨重现期、雨前干燥期的条件下，其对径流中典型重金属 Zn2+和Cu2+的去除效果和净化机制。结果表明，RCA在透水铺装系统中表现出更好的重金属去除效果，而RBA作为基层使用时去除效果较好。随着进水浓度、降雨重现期的增加，各透水铺装系统对Zn2+、Cu2+的去除率降低。而随着雨前干燥期的增加，各系统对Zn2+和Cu2+的去除率出现了小幅升高的现象。各系统对Cu2+的去除率均最高，始终保持在80%以上。两种再生骨料在透水铺装系统中均展现出一定的应用价值与使用前景。
Abstract:
The continuous increase of construction waste has brought serious harm to the urban environment, so it is urgent to seek solutions for its recycling and reuse. As a low cost and large volume recycled material, construction waste recycled aggregate has certain application potential in the field of water treatment. Recycled brick aggregate (RBA) and recycled concrete aggregate (RCA) were selected and used in the permeable pavement system. Five systems were built to analyze the removal efficiencies and purification mechanisms of Zn2+ and Cu2+ from runoff under different influent concentrations, rainfall return periods and antecedent dry periods. RCA showed better removal performances of heavy metals in the permeable pavement system, while RBA showed better removal performances when used as the subgrade. With the increase of influent concentration and rainfall return period, the removal rates of Zn2+ and Cu2+ by the permeable pavement system decreased. However, the removal rates of Zn2+ and Cu2+ increased slightly with the increase of the antecedent dry period. The removal rates of Cu2+ by all the systems were the highest, which were always above 80%. The two kinds of recycled aggregates showed certain application potential and prospect in the permeable pavement system.
