苏伊士中标中国西南地区规模最大污泥独立焚烧项目
9月27日，苏伊士中标为成都市第一城市污水污泥处理厂三期工程提供Thermylis®专利设备供货合同，并通过其技术服务为成都中心城区污泥的安全处置提供可靠的保证，协助当地实现其“十四五”生态环保目标，持续提升当地的生态环境治理能力。
成都地处长江上游，并已成为继重庆、上海、北京之后，中国第四个常住人口超过2000万的城市，对保护长江流域生态环境起到重要作用。在成都，每天全市数百万吨的污水在处理过程中，会产生约2200吨污泥，其中成都市第一城市污水污泥处理厂一、二期每天能处理污泥600吨。为妥善处置日益增长的污泥，该污水污泥处理厂进行污泥处理规模达800吨/天的三期工程建设。
该项目针对中国污泥低热值的特点，利用Thermylis®焚烧设施进行处理，项目建成后将成为中国西南地区规模最大的污泥独立焚烧项目。Thermylis®技术（预干化——高温流化床焚烧技术）已成功应用在集团于全球的40多个高温流化床污泥焚烧厂。该工艺实现污泥的稳定化、减量化和无害化处置，并收集污泥焚烧产生的蒸汽并回用于预干化系统，最大程度地实现能量回收利用，降低能源消耗，从而帮助客户减少碳排放并节约运行成本。该处理系统将通过清洁生产、超净排放的技术降低对环境的影响，节省填埋空间，将有效防止污泥对环境造成的二次污染。
在中国，苏伊士在提供污泥的消化、干化及焚烧处理等多种技术解决方案的同时，更在重庆、苏州工业园及相城区、扬州和上海建设及运营五座污泥处理厂。其中，位于苏州工业园的污泥处置及资源化利用项目凭借其有利于环境的设计获得中国及国际社会的认可，获评为法中委员会“气候变化解决方案”大奖、中国“环境污染第三方治理典型案例”及“江苏省循环经济示范项目”。
苏伊士亚洲地区首席执行官郭仕达表示：“苏伊士与成都合作伙伴缔结长期合作伙伴关系已十载，我们携手参与并见证了成都生态环境质量的持续改善。今天在成都能为体量如此之大的污泥处置项目提供服务是客户对我们的信任，令人深受鼓舞，也彰显了苏伊士通过富有韧性和创新性的解决方案为客户提供水务服务的能力。”

SUEZ Awarded the Largest Single Sludge Incineration Facility in Southwest China
On 27 September, SUEZ was awarded a contract to supply a Thermylis® sludge incinerator for Phase III of Chengdu No. 1 Municipal Wastewater and Sludge Treatment Plant. SUEZ technology will provide reliable and safe disposal of sludge for downtown Chengdu, help the city achieve its ecological and environmental goals under the 14th Five-Year Plan, and continuously improve the local capacity for ecological and environmental management.
Located in the upper reaches of the Yangtze River, Chengdu is the fourth city in China with a residential population of more than 20 million, after Chongqing, Shanghai, and Beijing. The city plays a pivotal role in the protection of the Yangtze River basin’s ecological environment. In Chengdu, every day millions of tonnes of municipal wastewater are treated, generating approximately 2,200 tonnes of sludge, of which, 600 tonnes are already treated by Phase I and Phase II facilities of the Chengdu Plant. To ensure appropriate treatment of the growing amounts of sludge, the wastewater and sludge treatment plant is undergoing a Phase III expansion that will add another 800 tonnes/day in sludge treatment capacity.
This additional load will be treated by the Thermylis® incinerator, suited to treat the low calorific value sludge in China. The plant is set to become the largest single sludge incineration facility of its kind in southwest China. This process has been successfully applied in more than 40 high-temperature fluidized bed sludge incineration plants worldwide. It stabilizes, reduces, and disposes of sludge harmlessly, and also recovers steam generated from sludge incineration and reuses it in the pre-drying system to maximize energy recovery and reduce energy consumption, helping customer to reduce its carbon footprint and save on operating costs. The treatment system will reduce the plant’s environmental impact through clean production and ultra-clean emission technology, save landfill space, and effectively prevent secondary pollution from sludge.
In China, SUEZ has been providing sludge digestion, drying and incineration solutions and has built and operates five sludge treatment plants in Chongqing, Suzhou Industrial Park and Xiangcheng District, Yangzhou and Shanghai. Among them, the sludge disposal and waste-to-energy project in the Suzhou Industrial Park has achieved national and international recognition for its environmentally beneficial design. The project received the Climate Change Solutions Innovation Award from the France-China Committee, as well as recognition as one of the “replicable case studies of third-party environmental treatment in industrial parks” in China and a Jiangsu Province Circular Economy Demonstration Project.
Steve Clark, CEO of SUEZ Asia, said, “SUEZ has maintained a decade-long partnership with the city of Chengdu. Together, we have witnessed and contributed to the continuous improvement of the city’s ecology and environment. Today, we are deeply encouraged by the trust placed in us by our customer to provide services for such a large sludge disposal project in Chengdu. This highlights SUEZ’s ability to provide access to water services with resilient and innovative solutions. ”
