威立雅将为瑞典布罗斯设计并建造未来污水处理厂!
威立雅水务技术通过其子公司VA-Ingenjörerna and Krüger赢得一份价值4亿瑞典克朗（约合4250万欧元）合同，将在瑞典布罗斯设计并建造一座全新的大型污水处理厂。着眼于环境及效率，新处理厂将展示集团在可持续污水处理领域所取得的最新进展。
布罗斯是瑞典西部第二大城市，自1960年代以来一直致力于可持续发展和低碳足迹。授予威立雅该合同的Borås Energi och Miljö´s (BEM)公司为布罗斯市提供区域供热、供冷、沼气、废弃物管理、供水与污水处理、能源及废弃物服务，也通过热电联产和水力发电厂进行发电。BEM公司运用其独特的回收再生模式，旨在将城市废物流中蕴含的能量转化为可再生能源，从而建立一座无需化石燃料的城市。
新污水处理厂将与当地电厂一同落户布罗斯南部的新能源环境中心，处理能力达21万人口当量并将以更有效的方式达到排放要求。该处理厂的移交时间定于2018年11月。
威立雅将呈现污水处理系统结合了集团众多的先进技术：从现代化预处理及生物处理，例如活性污泥工艺，到将可靠的Actiflo® 和 Hydrotech™ Discfilters工艺相结合的化学和雨水处理；之后采用Anita™ Mox高效脱氮工艺进一步处理高负荷氨氮。
污水处理厂的设计将采用节能技术，力求产生的污泥在附近沼气厂尽可能多地转化为能量。通过生物处理可回收磷资源。整座处理厂将由STAR™精确控制系统提供先进的控制监测。该系统借助在线监控，持续保证环境限制、能耗以及成本的最优运行状态，同时使得污水处理厂能够更加灵活地应对外界条件变化，特别是气候变化。
“威立雅所表现出的决心、积极性与发展意愿，确保了布罗斯污水处理厂将会符合最严格的环保标准。”BEM公司首席执行官Gunnar Peters先生表示。
威立雅水务技术执行副总裁Pierre Ribaute先生表示：“威立雅与布罗斯之间的合作已开展多年，致力于帮助城市减少其碳足迹。作为资源优化管理领域的全球领导者，威立雅非常适合帮助市政及工业客户制定水、废弃物和能源管理一体化战略。
该项目建立在威立雅和布罗斯10年以上长期合作的基础之上。依托威立雅供热及供冷管网的专业技术，布罗斯建成了一个37000立方米的储热池，如同巨大真空瓶用于储存生物质电厂在低功耗期间由所产生的热量，以满足高峰需求。通过平稳度过需求高峰，威立雅的解决方案可减少城市对化石燃料的依赖及其碳足迹。该系统是威立雅“智能供热网络”概念的绝佳范例，体现了集团优化指定地区能源效率的发展战略。
Veolia Water Technologies, through its subsidiaries VA-Ingenjörerna and Krüger, has won a SEK 400 million (approximately EUR 42.5 million) contract to design and build a new and ambitious wastewater treatment plant in Borås, Sweden. Focusing on environmental aspects and efficiency, the new facility will showcase the latest advancements in sustainable wastewater treatment.
Borås, the second largest city in Western Sweden, has been committed to sustainable development and low carbon footprint since the 1960’s. The Borås Energi och Miljö´s (BEM), who attributed this contract to Veolia, provides the city of Borås with district heating, district cooling, biogas, waste management, water and sewage treatment and energy and waste services. They also produce electricity in a combined heat and power plant and hydro power stations. By using their unique recycling model, they aim to convert the energy of the city´s waste streams into renewable valuables, and create a city free from fossil fuels.
The new wastewater treatment plant will be co-located with the local power plant at the new Energy and Environmental Center south from Borås. The new facility will have a 210,000 Population Equivalent capacity and will meet the emission requirements in a much more efficient way. Hand-over of the plant is scheduled for November 2018.
Cutting-edge Veolia technologies will provide a complete wastewater treatment cycle, from modern pretreatment and biological treatment, including a flexible activated sludge process, to chemical treatment and sewer overflow treatment with the proven Actiflo® process combined with Hydrotech™ Discfilters. The reject water will go through the Anita™ Mox process, particularly suited for streams highly loaded with ammonia.
The treatment plant is designed with the most energy-efficient technologies and with the aim to produce sludge with the highest possible potential to generate energy in the nearby biogas plant. Phosphorous will be recovered mainly through biological treatment which allows this essential resource to be reused as fertilizer.
Advanced control and monitoring will be provided throughout the plant by STAR™ Utility Solutions. This system is based on online surveys, continuously ensuring optimized operation in regards to environmental conditions, energy consumption and costs. It also provides a lot of flexibility, allowing the plant to be adapted to changing conditions caused by climate variations, for instance.
“The commitment, motivation and the will for development that Veolia has shown ensure that Borås will get a wastewater treatment plant of the highest environmental standards”, says Gunnar Peters, CEO of Borås Energi och Miljö.
Pierre Ribaute, Executive Vice President of Veolia Water Technologies, said: “Veolia has been working with the city of Borås for several years to help it reach its goal of reducing its carbon footprint. Being the global leader in environmental resource management, Veolia is uniquely suited to help municipalities and industries put in place a global strategy to manage their water, waste and energy. We are very proud to have been selected to design and build Borås’ new, sustainable wastewater treatment plant and look forward to continuing on a great partnership”.
This project follows on a long running collaboration between Veolia and Boras which started over 10 years ago. Relying on Veolia’s expertise in heat and cooling networks, Boras built a 37,000 cubic meter tank that, like a massive vacuum flask, stores the heat produced by a biomass plant during periods of low consumption and use it to cover peak demand. By smoothing peak consumption, Veolia’s solution reduces the need to use fossil fuels and in turn the city's carbon footprint. The system is an excellent example of Veolia's strategy of developing a "smart heat grid" concept, the aim of which is to optimize energy efficiency for a given area.
