“…The bioretention tank, as a rainwater treatment facility in urban rainwater low impact development technology (LID), can not only store rainwater through the adsorption capacity of internal structure and soil matrix materials, but also effectively attenuate the flood peak flow and runoff of rainwater, and improve rainwater quality through precipitation, filtration, microbial processes and vegetation absorption (Wong & Somes 1995;Liu & Davis 2014;Jiang et al 2018;Ashoori et al 2019). The conventional bioretention tanks can effectively remove total suspended solids (TSS), heavy metals/metals, pathogens and oils from rainwater (Wilcock et al 2012;Halaburka et al 2017;Osman et al 2019;Guerra & Kim 2020). More studies have shown that traditional biological retention tanks can remove 29% ∼ 99% TSS and 98% oil pollution, and can also effectively remove oil pollution with an annual average removal rate of heavy metals such as zinc, copper and lead reaching 98%,99 and 81%, respectively (Feng et al 2001;Li & Davis 2009;Li & Davis 2014;Wang et al 2015;Li et al 2016;Soleimanifar et al 2016;Zhang et al 2019).…”

The traditional bioretention systems possess a remarkably low nitrogen and phosphorus removal effect. The removal rate fluctuates greatly, and even appears as negative removal of nitrogen and phosphorus. The four simulated bioretention experimental columns with different bilayer media, packing composition and structure were constructed. Based on the traditional fillers, the modified composite fillers with hydroxy-aluminum and modified vermiculite sludge particle (HAVSP) were added. The traditional filler (C1) and the modified composite filler (C2) were added respectively, moreover the saturated zones were set up to enhance the effect of nitrogen and phosphorus removal. Removal of nutrients from experimental columns by simulated runoff efficiency was evaluated and compared. In addition, the effect of media depth on phosphorus retention and denitrifying enzyme activity in bioretention columns was also evaluated. The experimental column #2 filled with C2 had the optimum removal effect on total phosphorus (93.70%), however, the removal effect of total phosphorus by filling C1 experimental columns was insufficient (57.36%). Designed to remove nitrate (NO3−-N) and total nitrogen (TN), the experimental column #4 showed the best performance (83.54% and 92.15%, respectively). In this study, we propose a fold-flow bioretention system by filling HAVSP in combination with saturated zones. The runoff water quality can be effectively improved, and a new bioretention cell configuration can be provided for efficient stormwater treatment.

“…Field-based studies categorize LID systems into infiltration-and storage-type facilities and have evaluated the water cycle effect and the ability of these systems to reduce nonpoint sources [20][21][22]. Moreover, previous studies have established the flood control capability and nonpoint source reduction effect by element facilities such as permeable pavements [23,24], green roofs [25], vegetation-type facilities [26], and fine-media stormwater filtration systems [27].…”

A defining characteristic of the urbanization is the transformation of existing pervious areas into impervious areas during development. This leads to numerous hydrologic and environmental problems such as an increase in surface runoff due to excess rainfall, flooding, the deterioration of water quality, and an increase in nonpoint source pollution. Several studies propose supplementary measures on environmental change problems in development areas using the low impact development technique. This study investigated the reduction of nonpoint source pollutant loads and flooding in catchments through urban catchment rainfall–runoff management. For the quantitative assessment of flood disasters and water pollution problems, we propose a reliability evaluation technique. This technique refers to a series of analysis methods that determine the disaster prevention performance of the existing systems. As the two factors involve physical quantities of different dimensions, a reliability evaluation technique was developed using the distance measure method. Using the storm water management model, multiple scenarios based on synthetic rainfall in the catchment of the Daerim 2 rainwater pumping station in Seoul, South Korea, were examined. Our results indicate the need for efficient management of natural disaster risks that may occur in urban catchments. Moreover, this study can be used as a primary reference for setting a significant reduction target and facilitating accurate decision making concerning urban drainage system management.

“…In terms of green infrastructure, Yan et al studied the hydrology and pollutant removal performance of the LID (low impact development)/GI (green infrastructure) system in the arid and semi-arid areas in the United States (Jiang et al 2015). Heidi et al studied the soil permeability, compared the effects of high permeation soil and low permeation soil on the permeation rate and effective water-storage depth (Guerra & Kim 2020). Wei et al took Alar, Xinjiang as an example,combined with the actual situation of the region, the idea of GI network construction will be put forward in oasis cities in arid regions (Wei et al 2020).…”

In order to make the sponge city construction model more consistent with the inherent characteristics of the city, this paper constructs classification of the sponge city construction index system. We carry out multivariate statistical and cluster analysis based on GIS and classify the different regions of mainland China, put forward key points of construction for different types of regions. The results show that climatic factor, hydrological factor and soil factor are the main factors affecting sponge city construction, followed by city scale and level of urban economic development, the third is underlying surface type and geomorphological type. The cities are classified into ten clusters, and they present a continuously zonal or flaky distribution from northeast to southwest on the whole, more than 80% of cities obviously present a continuously zonal or flaky distribution. Each of the nine clusters has at least one pilot city, which can be used as a reference for construction.
