关键技术攻关助力多水源格局下的从源头到龙头的供水安全

2014年12月南水北调中线工程通水后,京津冀区域,特别是京津特大城市群,形成了"南水北调来水和本地水资源互联互调"的多水源供水新格局.南水北调中线工程在一定程度上缓解了京津冀区域严重缺水的局面.与此同时,其供水安全保障也面临了巨大挑战.2017年国家水体污染控制与治理科技重大专项(简称"水专项")设置了"多水源格局下城市供水安全保障技术体系构建"科研项目,以保障北京市多水源格局下的安全供水为核心,优化、集成既有水专项相关研究成果.探明丹江口水源超长距离输送过程中水质变化规律,突破南水北调中线原水水质预警技术、生态型水源地保护管理技术.以多水源水质水量变化和水厂工艺适应性为约束条件,形成基于水源-水厂-管网联动的水质安全保障集成技术;以智慧供水建设为切入点,建设多层次、全方位预警决策和风险管控平台,构建基于在线监测和智能决策的大型管网节水节能、水质提升的优化调度技术,进而全面提升北京市供水安全保障.     

“引江济太”新建工程对梅梁湾总磷总氮分布的影响

2016年以来,太湖水体总磷(TP)浓度上升且在2017年暴发大面积蓝藻,严重威胁了太湖水环境安全。2020年“引江济太”新建工程———新孟河延伸拓浚工程和新沟河延伸拓浚工程正式启用,将在已投入使用的望虞河引水工程基础上进一步提高进出太湖水量,为改善太湖水环境提供新的解决方案。文中通过建立太湖二维水动力-水质模型,模拟并分析“引江济太”新建工程中,太湖梅梁湾在不同季节盛行风下TP和总氮(TN)的迁移扩散规律。模拟结果表明,在夏半季与冬半季盛行风向作用下,不同引排量水对梅梁湾水域TP和TN的浓度影响与分布趋势存在差异性,当引排水量增加时,区域水体水质提升。     

Introducing total water cycle management in Sydney: a Kogarah Council initiative

Away from traditional supply option of building dams, we need to adopt new supply options that can be incorporated into urban development and at household-level technology, including rainwater harvesting and wastewater reclamation. While technological advancements have made them possible, economic arguments and to larger extent a lack of political leadership have been keeping these options at pilot stage. The Kogarah Council is amongst a few NSW municipalities who have embarked on a comprehensive review of its water management practices. This journey has resulted in changing the Council's focus from traditional drainage pits and pipes to a much broader approach to water cycle management. In 2003 the Kogarah Council became the first one in Sydney to adopt TWCM principles into its Sustainability Management Plan. “Reduction in per capita water demand in Kogarah” was identified as a key sustainability indicator in the plan. At the same time, the Council recognised that while it had a statutory responsibility for managing stormwater, a successful partnership with the Sydney Water Corporation (responsible for water and wastewater) was vital to bringing together data, resources, and knowledge to develop and implement TWCM projects. The project developed a TWCM strategy for the Beverley Park catchment to identify priority projects in the catchment that produce the most cost-effective water savings. The Council has since endorsed the strategy and is committed to three priority projects identified for implementation in 2004/05: participation in Sydney Waters “Every Drop Counts” Business Program, the Beverley Park Water Reclamation Project, and the Rainwater Tanks in Schools Project. The first project will enhance the on-going water efficiency roll-outs from the Sydney Water Corporation, and the other two projects focus on creating new water sources. By 2005/06, the implementation of these projects will save up to 150 ML of drinking water every year in Kogarah. This paper presents an insight into this innovative project and provides the current status of the three priority projects.

黄浦江上游水源地水质污染分析与突发性水污染事件分级

对2007-2010年黄浦江上游水源地水质调查数据进行分析后认为：NH3-N和CODMn污染主要来自其上游的淀山湖及省界来水,淀山湖、拦路港斜塘及黄浦江上游主干水质污染程度有逐年降低趋势,淀山湖尤为明显,黄浦江几大支流依据污染程度排序为大泖港〉园泄泾〉斜塘〉太浦河;黄浦江原水中的NH3-N和CODMn可以通过臭氧＋生物活性炭的深度处理工艺有效降低,使出厂水水质达标;移动源污染（船舶）已成为黄浦江水源地最难以控制的污染源之一,并成为原水供应最主要的风险;建议将黄浦江上游水源地区域内外发生的突发性水污染事件分为四级,并提出相应的分级标准。     

Achieving sustainable recycled water initiatives through public participation

Sustainability or “Development that meets the needs of the present without compromising the ability of future generations to meet their own needs” [1] remains a relatively new concept for the water industry. The challenge is to develop sustainable recycled water projects that meet the needs of a water business as the responsible service authority, while at the same time meeting the individual needs of a particular community. The community consultation model that has been adopted by Grampians Wimmera Mallee Water to assist in the implementation of our urban Water Quality Improvement Program is widely considered to be a water industry benchmark. The integration of this tried and tested consultation model with our recently adopted Recycled Water Strategy is now providing us with a framework for informing and educating local communities and other key stakeholders about recycled water. The model also encourages local stakeholders to play a major role in identifying and evaluating opportunities for potential sustainable recycled water projects to meet the needs of their particular community. The successful elements of the model that have been further developed include community newsletters, information packages and public workshops. Initial newsletters and an information workshop seek local community input into identifying potential projects. Subsequent information packages and workshop(s) provide further information for interested individuals and/or organisations in the development of project proposals. Local community input into prioritising the criteria used to assess project proposals are also sought, usually through these workshop(s). Grampians Wimmera Mallee Water has challenged the perceived ‘we know what's best for you’ culture by providing key stakeholders with the opportunity to have informed input during the decision making process. This is allowing us to develop sustainable recycled water projects that take into consideration the needs of individual communities and key stakeholders. It is also assisting us to build strong relationships with our customers through educated and informed communities.

Ozone Application for Arsenic and Manganese Treatment at the City of White Rock,BC, Canada

The City of White Rock purchased the water utility on October 30, 2015, from EPCOR Utilities Inc. The City of White Rock‘s water utility provides safe and clean drinking water to its residents. The drinking water is obtained from the Sunnyside Uplands Aquifer. To ensure water supplied is of the highest quality, the City collaborated with the RES‘EAU-WaterNET, to conduct research to evaluate and identify technologies that are capable of providing a significant reduction of arsenic and manganese, to improve water quality. The City submitted a grant application to the Clean Water and Wastewater Fund (CWWF) for the construction of a water treatment plant to reduce arsenic and manganese in drinking water. The Government of Canada and the Province of British Columbia provided funding from the Clean Water and Wastewater Fund (CWWF) to the City of White Rock for the “Arsenic and Manganese Water Treatment Project. The City awarded a contract for the Design Build for a Water Treatment Plant to provide a major reduction in arsenic and manganese in drinking water. The Design Build project utilized the scientific findings from the research conducted. The construction of the plant started in March 2018, and the project is expected to be completed by March 2019.
