张贵庄污水处理厂项目位于天津东丽区,总投资达30亿元,占地达45万平方米,是天津市首个采用PPP模式运营的存量污水处理项目,也是中国铁建首个投建营一体的市政污水处理厂。

中铁十四局承建的污水处理区域主要包含初沉池、生物池及污泥泵房等33个单体,引入自动化控制系统和智慧水务平台,具有安全可靠、节能环保、绿色经济的特点,能够保证污水稳定达标处理,使尾水水质达到最高标准一级A标排放。

为保证施工精度,项目部严格按照施工方案作业,加强施工过程中的实时监测和协调,克服了混凝土浇筑困难、软弱土层沉井下沉速率控制要求严格等难题。施工中,采用无粘结预应力施工技术,提高了结构的耐久性和抗裂性能,延长了使用寿命,?提高了可维护性。

此外,该污水处理厂注重资源回收利用,能够将污泥转化为生物质能源或有机肥料;将出水回用于农业灌溉、工业循环、城市景观等领域;将余热回收利用于供暖或制冷等方面,还与城市环境相融,构建生态、生活、生产三生共融、服务社会与自然的城市新型空间。

Zhangguizhuang Sewage Treatment Plant project is located in Dongli District, Tianjin, with a total investment of 3 billion yuan, covering an area of 450,000 square meters, is the first stock sewage treatment project operated by PPP mode in Tianjin, and is also the first municipal sewage treatment plant integrated by China Railway Construction.

The sewage treatment area constructed by the 14th Bureau of China Railway mainly includes 33 individual units such as primary sedimentation tank, biological tank and sludge pump room. The introduction of automatic control system and intelligent water platform has the characteristics of safety and reliability, energy saving and environmental protection, and green economy, which can ensure the stable treatment of sewage and make the water quality of the tailings reach the highest standard A standard discharge.

In order to ensure the construction accuracy, the project department works strictly in accordance with the construction plan, strengthens the real-time monitoring and coordination during the construction process, and overcomes the difficulties of concrete pouring and strict control requirements for the sinking rate of caisson in soft soil. In construction, the non-bonded prestressed construction technology is used to improve the durability and crack resistance of the structure and extend the service life. Improved maintainability.

In addition, the sewage treatment plant focuses on resource recycling and can convert sludge into biomass energy or organic fertilizer; Reuse the water for agricultural irrigation, industrial recycling, urban landscape and other fields; The waste heat is recycled for heating or cooling, and it is also integrated with the urban environment to build a new urban space that integrates ecology, life and production, and serves society and nature.
