威立雅將為瑞典布羅斯設(shè)計并建造未來污水處理廠!
威立雅水務(wù)技術(shù)通過其子公司VA-Ingenjörerna and Krüger贏得一份價值4億瑞典克朗（約合4250萬歐元）合同，將在瑞典布羅斯設(shè)計并建造一座全新的大型污水處理廠。著眼于環(huán)境及效率，新處理廠將展示集團在可持續(xù)污水處理領(lǐng)域所取得的最新進展。
布羅斯是瑞典西部第二大城市，自1960年代以來一直致力于可持續(xù)發(fā)展和低碳足跡。授予威立雅該合同的Borås Energi och Miljö´s (BEM)公司為布羅斯市提供區(qū)域供熱、供冷、沼氣、廢棄物管理、供水與污水處理、能源及廢棄物服務(wù)，也通過熱電聯(lián)產(chǎn)和水力發(fā)電廠進行發(fā)電。BEM公司運用其獨特的回收再生模式，旨在將城市廢物流中蘊含的能量轉(zhuǎn)化為可再生能源，從而建立一座無需化石燃料的城市。
新污水處理廠將與當(dāng)?shù)仉姀S一同落戶布羅斯南部的新能源環(huán)境中心，處理能力達21萬人口當(dāng)量并將以更有效的方式達到排放要求。該處理廠的移交時間定于2018年11月。
威立雅將呈現(xiàn)污水處理系統(tǒng)結(jié)合了集團眾多的先進技術(shù)：從現(xiàn)代化預(yù)處理及生物處理，例如活性污泥工藝，到將可靠的Actiflo® 和 Hydrotech™ Discfilters工藝相結(jié)合的化學(xué)和雨水處理；之后采用Anita™ Mox高效脫氮工藝進一步處理高負荷氨氮。
污水處理廠的設(shè)計將采用節(jié)能技術(shù)，力求產(chǎn)生的污泥在附近沼氣廠盡可能多地轉(zhuǎn)化為能量。通過生物處理可回收磷資源。整座處理廠將由STAR™精確控制系統(tǒng)提供先進的控制監(jiān)測。該系統(tǒng)借助在線監(jiān)控，持續(xù)保證環(huán)境限制、能耗以及成本的最優(yōu)運行狀態(tài)，同時使得污水處理廠能夠更加靈活地應(yīng)對外界條件變化，特別是氣候變化。
“威立雅所表現(xiàn)出的決心、積極性與發(fā)展意愿，確保了布羅斯污水處理廠將會符合最嚴(yán)格的環(huán)保標(biāo)準(zhǔn)。”BEM公司首席執(zhí)行官Gunnar Peters先生表示。
威立雅水務(wù)技術(shù)執(zhí)行副總裁Pierre Ribaute先生表示：“威立雅與布羅斯之間的合作已開展多年，致力于幫助城市減少其碳足跡。作為資源優(yōu)化管理領(lǐng)域的全球領(lǐng)導(dǎo)者，威立雅非常適合幫助市政及工業(yè)客戶制定水、廢棄物和能源管理一體化戰(zhàn)略。
該項目建立在威立雅和布羅斯10年以上長期合作的基礎(chǔ)之上。依托威立雅供熱及供冷管網(wǎng)的專業(yè)技術(shù)，布羅斯建成了一個37000立方米的儲熱池，如同巨大真空瓶用于儲存生物質(zhì)電廠在低功耗期間由所產(chǎn)生的熱量，以滿足高峰需求。通過平穩(wěn)度過需求高峰，威立雅的解決方案可減少城市對化石燃料的依賴及其碳足跡。該系統(tǒng)是威立雅“智能供熱網(wǎng)絡(luò)”概念的絕佳范例，體現(xiàn)了集團優(yōu)化指定地區(qū)能源效率的發(fā)展戰(zhàn)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.
