摘要： A bioretention unit (BRU) or cell is a green infrastructurepractice that is widely used as a low impact development (LID) techniquefor urban stormwater management. Bioretention is considered a goodfit for use in China’s sponge city construction projects. However,studies on bioretention design, which incorporates site-specific environmentaland social-economic conditions in China are still very much needed.In this study, an experimental BRU, consisted of two cells plantedwith and ,was tested with eighteen synthesizedstorm events. Three levels (high, median, low) of flows and concentrationsof pollutants (TN, TP and COD) were fed to the BRU and the performanceof which was examined. The results showed that the BRU not only delayedand lowered the peak flows but also removed TN, TP and COD in variousways and to different extents. Under the high, medium and low inflowrate conditions, the outflow peaks were delayed for at least 13 minutesand lowered at least 52%. The two cells stored a maximum of 231 mmand 265 mm for turf grass and respectively. For both cells the total depth available for storagewas 1,220 mm, including a maximum 110 mm deep ponding area. The largestinfiltrate rate was 206 mm/h for both cells with different plants.For the eighteen events, TP and COD were removed at least 60% and42% by mean concentration, and 65% and 49% by total load, respectively.In the reservoir layer, the efficiency ratio of removal of TN, TPand COD were 52%, 8% and 38%, respectively, within 5 days after runoffevents stopped. Furthermore, the engineering implication of the hydrologicaland water quality performances in sponge city construction projectsis discussed.

Hydrologic experiments and modeling of two laboratory bioretention systems under different boundary conditions

Ruifen Liu, Elizabeth Fassman-Beck

《环境科学与工程前沿（英文）》 2017年 第11卷 第4期 doi: 10.1007/s11783-017-0951-5

摘要： Hydrologic performance of bioretention systems is significantly influenced by the media composition and underdrain configuration. This research measured hydrologic performance of column-scale bioretention systems during a synthetic design storm of 25.9 mm, assuming a system area:catchment area ratio of 5%. The laboratory experiments involved two different engineered media and two different drainage configurations. Results show that the two engineered media with different sand aggregates were able to retain about 36% of the inflow volume with free drainage configuration. However, the medium with marine sand is better at delaying the occurrence of drainage than the one with pumice sand, denoting the better detention ability of the former. For both engineered media, an underdrain configuration with internal water storage (IWS) zone lowered drainage volume and peak drainage rate as well as delayed the occurrence of drainage and peak drainage rate, as compared to a free drainage configuration. The USEPA SWMM v5.1.11 model was applied for the free drainage configuration case, and there is a reasonable fit between observed and modeled drainage-rates when media-specific characteristics are available. For the IWS drainage configuration case, air entrapment was observed to occur in the engineered medium with marine sand. Filling of an IWS zone is most likely to be influenced by many factors, such as the structure of the bioretention system, medium physical and hydraulic properties, and inflow characteristics. More research is needed on the analysis and modeling of hydrologic process in bioretention with IWS drainage configuration.

A critical literature review of bioretention research for stormwater management in cold climate and future

Hannah Kratky, Zhan Li, Yijun Chen, Chengjin Wang, Xiangfei Li, Tong Yu

《环境科学与工程前沿（英文）》 2017年 第11卷 第4期 doi: 10.1007/s11783-017-0982-y

摘要： Bioretention is a popular best management practice of low impact development that effectively restores urban hydrologic characteristics to those of predevelopment and improves water quality prior to conveyance to surface waters. This is achieved by utilizing an engineered system containing a surface layer of mulch, a thick soil media often amended with a variety of materials to improve water quality, a variety of vegetation, and underdrains, depending on the surrounding soil characteristics. Bioretention systems have been studied quite extensively for warm climate applications, but data strongly supporting their long-term efficacy and application in cold climates is sparse. Although it is apparent that bioretention is an effective stormwater management system, its design in cold climate needs further research. Existing cold climate research has shown that coarser media is required to prevent concrete frost from forming. For spring, summer and fall seasons, if sufficient permeability exists to drain the system prior to freezing, peak flow and volume reduction can be maintained. Additionally, contaminants that are removed via filtration are also not impacted by cold climates. In contrary, dissolved contaminants, nutrients, and organics are significantly more variable in their ability to be removed or degraded via bioretention in colder temperatures. Winter road maintenance salts have been shown to negatively impact the removal of some contaminants and positively impact others, while their effects on properly selected vegetation or bacteria health are also not very well understood. Research in these water quality aspects has been inconsistent and therefore requires further study.

摘要： Green infrastructures such as rain gardens can benefit onsite reduction of stormwater runoff, leading to reduced combined sewer overflows. A pilot project was conducted to evaluate the impact of rain gardens on the water quality and volume reduction of storm runoff from urban streets in a combined sewer area. The study took place in a six-block area on South Grand Boulevard in St. Louis, Missouri. The impact was assessed through a comparison between the pre-construction (2011/2012) and the post-construction (2014) phases. Shortly after the rain gardens were installed, the levels of total suspended solids, chloride, total nitrogen, total phosphorous, zinc, and copper increased. The level of mercury was lower than the detection level in both phases. was the only parameter that showed statistically significant decrease following the installation of rain gardens. The likely reason for initial increase in monitored water quality parameters is that the post-construction sampling began after the rain gardens were constructed but before planting, resulted from soil erosion and wash-out from the mulch. However, the levels of most of water quality parameters decreased in the following time period during the post-construction phase. The study found 76% volume reduction of stormwater runoff following the installation of rain gardens at one of studied sites. Statistical analysis is essential on collected data because of the encountered high variability of measured flows resulted from low flow conditions in studied sewers.

摘要： Hybrid system of LID technologies and conventional system was examined. Bioretention areas, rainwater harvesting, and xeriscaping were considered. Technology feasibility was simulated for land use and population density. Synergistic effects of technologies were quantified in defined zones. Uncertainty test was conducted with pedigree matrix and Monte Carlo analysis. Low-impact development (LID) technologies, such as bioretention areas, rooftop rainwater harvesting, and xeriscaping can control stormwater runoff, supply non-potable water, and landscape open space. This study examines a hybrid system (HS) that combines LID technologies with a centralized water system to lessen the burden on a conventional system (CS). CS is defined as the stormwater collection and water supply infrastructure, and the conventional landscaping choices in the City of Atlanta. The study scope is limited to five single-family residential zones (SFZs), classified R-1 through R-5, and four multi-family residential zones (MFZs), classified RG-2 through RG-5. Population density increases from 0.4 (R-1) to 62.2 (RG-5) persons per 1,000 m . We performed a life cycle assessment (LCA) comparison of CS and HS using TRACI 2.1 to simulate impacts on the ecosystem, human health, and natural resources. We quantified the impact of freshwater consumption using the freshwater ecosystem impact (FEI) indicator. Test results indicate that HS has a higher LCA single score than CS in zones with a low population density; however, the difference becomes negligible as population density increases. Incorporating LID in SFZs and MFZs can reduce potable water use by an average of 50% and 25%, respectively; however, water savings are negligible in zones with high population density (i.e., RG-5) due to the diminished surface area per capita available for LID technologies. The results demonstrate that LID technologies effectively reduce outdoor water demand and therefore would be a good choice to decrease the water consumption impact in the City of Atlanta.

摘要：

水是一种有限而宝贵的资源。新加坡的国家水源有4种补给方式，其中之一是自然降水。雨水径流会收集污染物，并将其富集到排水系统和水库中。在当地雨水径流中发现的主要富营养污染物包括硝酸盐和磷酸盐，这些富营养污染物可能导致富营养化。在有植物存在的情况下，生物滞留系统可以有效去除这些污染物。本文探讨了植物特性对雨水径流中营养性污染物的植物修复作用，并将其应用于生物防护系统中。所研究的植物物种在叶绿素含量、叶片绿色的浓度、生物量的产生以及硝酸盐和磷酸盐去除方面表现出了差异。一般而言，干生物量与硝酸盐和磷酸盐的去除程度相关（r = 0.339~0.501）。本地树种的根、叶和总干生物量显示出与硝酸盐去除程度之间的中等至强相关性（r 分别为0.811、0.657和0.727）。速生植物的叶片干生物量与两种污染物的去除程度也显示出中等至强相关性（r 分别为0.707和0.609）。低生长植株的根系生物量与磷的去除有很强的相关性（r = 0.707），但与硝酸盐去除的相关性较弱（r = 0.557）。这些结果对于选择用于生物滞留系统的植物是有价值的。
