摘要

本研究的目的是描述一个住宅集水区的雨水径流特征，评估目前蓄水池对不同污染物的去除效率，并评估如何通过控制蓄水池雨水滞留时间来提高其效率。分析的污染物为总悬浮固体(TSS)、总金属和氨。径流污染物浓度与文献研究结果一致。原始池塘的设计使得大多数分析污染物的滞留时间较短，导致与类似类型的池塘相比，去除效率低于预期。池塘的改造包括在出水口增加一个闸门，以便长时间保留雨水。改造后，TSS、NH3-N和锌的去除率分别从39%提高到90%、10%提高到84%和20%提高到42%。

Pollutant removal efficiency of a retrofitted stormwater detention pond

The objectives of this study were to characterize the stormwater runoff for a residential catchment, evaluate the present detention pond removal efficiency for different pollutants, and evaluate how its efficiency can be increased by controlling the pond stormwater retention time. The analysed pollutants were total suspended solids (TSS), total metals and ammonia. Runoff pollutant concentrations were generally found to agree with literature for the small residential catchment. The design of the original pond was such that low retention times of most analysed pollutants occurred, causing a lower than expected removal efficiency when compared to similar types of ponds. The retrofitting of the pond consisted of adding a sluice gate at the outlet in order to retain stormwater for longer periods of time. The retrofit allowed drastic improvement of the removal efficiency for TSS, NH3-N and zinc, from 39 to 90%, 10 to 84%, and 20 to 42%, respectively.

期刊介绍： The Water Quality Research Journal publishes peer-reviewed, scholarly articles on the following general subject areas: Impact of current and emerging contaminants on aquatic ecosystems Aquatic ecology (ecohydrology and ecohydraulics, invasive species, biodiversity, and aquatic species at risk) Conservation and protection of aquatic environments Responsible resource development and water quality (mining, forestry, hydropower, oil and gas) Drinking water, wastewater and stormwater treatment technologies and strategies Impacts and solutions of diffuse pollution (urban and agricultural run-off) on water quality Industrial water quality Used water: Reuse and resource recovery Groundwater quality (management, remediation, fracking, legacy contaminants) Assessment of surface and subsurface water quality Regulations, economics, strategies and policies related to water quality Social science issues in relation to water quality Water quality in remote areas Water quality in cold climates The Water Quality Research Journal is a quarterly publication. It is a forum for original research dealing with the aquatic environment, and should report new and significant findings that advance the understanding of the field. Critical review articles are especially encouraged.
