雨水排放费制度是一种控制降雨径流排放的有效经济管理手段。在城市内涝、面源污染等问题亟待解决及海绵城市建设的大背景下,研究一种具有区域适用性的雨水排放费分区量化征收办法具有重要的现实意义。选择北京市东城区面积为1. 934 km~2的某区域为研究对象,按用地类型将其划分为4种功能分区,依据各功能分区下垫面特征及污染本底情况提出了一套适用于建成区降雨径流水量排放的费用计算公式。通过建立城市排水管网模型模拟研究区不同重现期设计降雨情景下的排口出流量,计算不同功能分区在不同重现期场次降雨情景下的水量费用,以此验证雨水排放费用计算方法及分区量化征收办法的合理性和适用性。结果表明,对于居民住宅区、商业区/商务行政办公区,不同重现期单场次降雨人均水量费用均值分别为0. 25、0. 81元/人,计算结果合理,对鼓励人们进行雨水资源化利用、参与海绵城市建设可起到积极的推动作用。 相似文献

A清洁城市:雨水利用 一举多得
德国:作为世界上雨水利用最先进的国家之一,雨水用途广泛。首要用途就是建造水景观和清洁改善环境。德国联邦及各州有关法律规定,新建或改建开发区必须考虑雨水利用系统,若无雨水利用措施,政府将征收开发商雨水排放设施费和雨水排放费。 相似文献

Urban stormwater runoff is both a significant pollution source and a potentially valuable resource. This study compares stormwater management in two cities: Singapore and Berlin, Germany. In comparing the strategies for stormwater management, we illustrate how differences in geography (e.g., land and water availability), urban infrastructure, regulatory regimes, legislation and intensives between the two cities have led to different solutions for stormwater management. Singapore, faced with a serious issue of water scarcity, has placed an increasing emphasis on stormwater management through developing a comprehensive network of drains and canals, mainly with the aim of controlling flooding and potable water supply. In contrast, in Berlin, concerns for the protection of surface water quality and non-potable water supply in the urban areas have resulted in a shift in management goals towards a low impact solution based on source control. The cost analysis indicated that the decentralized rainwater harvesting as practiced in Berlin leads to a higher economic efficiency where potable water can be substituted by stormwater, compared to the centralized drainage system in Singapore. Additionally, green roofs result in energy savings by serving as mitigation strategies against the effect of urban heat islands and global warming. In the near future, it is envisioned that a combination of both conventional and decentralized urban stormwater management will prove to be the most practical solution for most cities. 相似文献

Integrated Urban Water Management (IUWM) approach is an important strategy for urban water utilities to improve water security and system resilience. This study proposes a novel approach to combine recycled water and stormwater. This novel mixing method of capturing and treating stormwater at various locations along the recycled water pipeline and injecting treated stormwater in to the recycled water pipe line is unknown to have been practiced anywhere in the world. Water quality control of combined water is a vital factor for the safe use, as mixing percentage of stormwater is decided based on availability. A method to determine the water quality before mixing is required. Therefore, this paper investigates the appropriateness of the mass balance method to compute combined water quality and proposes a guideline for water quality of combined water. 相似文献

Stormwater runoff poses a great challenge to the scientific assessment of the effects of diffuse pollution sources on receiving waters. In this study, a self-organizing map (SOM), a research tool for analyzing specific patterns in a large array of data, was applied to the monitoring data obtained from a stormwater monitoring survey to acquire new insights into stream water quality profiles under different rainfall conditions. The components of the input data vectors used by the SOM included concentrations of 10 metal elements, river discharge, and rainfall amount which were collected at the inlet and endpoint of an urban segment of the Yeongsan River, Korea. From the study, it was found that the SOM displayed significant variability in trace metal concentrations for different monitoring sites and rainfall events, with a greater impact of stormwater runoff on stream water quality at the upstream site than at the downstream site, except under low rainfall conditions (≤4 mm). In addition, the SOM clearly determined the water quality characteristics for “non-storm” and “storm” data, where the parameters nickel and arsenic and the parameters chromium, cadmium, and lead played an important role in reflecting the spatial and temporal water quality, respectively. When the SOM was used to examine the efficacy of stormwater quality monitoring programs, between 34 and 64% of the sample size in the current data set was shown to be sufficient for estimating the stormwater pollutant loads. The observed errors were small, generally being below 10, 6, and 20% for load estimation, map resolution, and clustering accuracy, respectively. Thus, the method recommended may be used to minimize monitoring costs if both the efficiency and accuracy are further determined by examining a large existing data set. 相似文献
