The TREENET inlet is an emerging water-sensitive urban design technology that consists of a novel kerb side inlet coupled with a leaky well infiltration system. The inlets have been retrofitted to existing roads since 2006; however, there is currently little information available on the effectiveness of these inlet and leaky well systems. This study investigated the performance of the kerb side inlets and leaky well system for water quality improvement prior to infiltration to native soil. The leaky wells included four filter media types, namely gravel, water treatment solids, sandy loam and clay. To compare the performance of the four filter media types, batch and column studies were performed in the laboratory. The best performance was observed using the sandy loam as a filter media, followed by clay, water treatment solids and then gravel. The selection of effective media for removal of heavy metals is important as each media type has different pollutant removal capacity, infiltration and clogging performance.
TREENET 进水口是一种新兴的水敏城市设计技术,由一种新型的路边进水口与渗漏井渗透系统组成。自 2006 年以来,这些进水口已经被改装到现有道路上;然而,目前关于这些进水口和渗漏井系统的有效性的信息很少。本研究在渗透到原生土壤之前,调查了路边进水口和渗漏井系统对水质改善的性能。渗漏井包括四种过滤介质类型,即砾石、水处理固体、砂壤土和粘土。为了比较四种过滤介质类型的性能,在实验室进行了批量和柱研究。使用砂壤土作为过滤介质时观察到最佳性能,其次是粘土、水处理固体,然后是砾石。选择有效的重金属去除介质很重要,因为每种介质类型的污染物去除能力、渗透和堵塞性能都不同。
