Construction and demolition (C&D) waste generated in the process of urban development has rapidly increased in recent years around the world in large quantities without proper reuse, resulting in negative environmental impact. Adsorption experiments were carried out by using red brick, burn-free brick and concrete brick, respectively. Results indicated that the hydraulic conductivity was influenced by the waste bricks type. And phosphorus removal increased with increasing initial aqueous phosphorus concentrations and the contacting time. While it decreased with co-exist anions (such as SO₄^2-, Cl⁻, NO₃⁻ and HCO₃⁻), and no evident variation was found for the adsorption capacity of phosphorus for the three kinds of waste bricks while the solution pH ranged from 5 to 9. Thus, we can conclude that demolition waste bricks showed a great application potential as infiltration system geomedia in terms of hydraulic conductivity and phosphorus adsorption.

近年来，在全球范围内，城市发展过程中产生的拆建废物迅速大量增加，而没有得到适当的再利用，对环境造成了负面影响。分别使用红砖，免烧砖和混凝土砖进行吸附实验。结果表明，水力传导率受废砖类型的影响。随着初始含水磷浓度和接触时间的增加，除磷量也增加。虽然它与共存阴离子降低（如SO ₄ ^2-，氯^-，NO ₃ ^-和HCO ₃ ^-），当溶液的pH值在5至9之间时，三种废砖对磷的吸附能力均未见明显变化。因此，我们可以得出的结论是，拆除的废砖作为渗透系统土工料具有很大的应用潜力。在水力传导率和磷吸附方面。
