- 摘要:
- 根据《北京市加快污水处理和再生水利用设施建设三年行动方案(2016—2019)》要求,垡头污水处理厂改扩建工程属于北京市中心城区批准立项建设的11项污水处理项目之一。该污水处理厂现状规模为2×104 m3/d,采用CASS工艺,占地为1.3 hm2。改扩建工程要求在不新征地、不停水情况下,处理规模扩建至10×104 m3/d,出水水质由目前的《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级B标准提高到北京市《城镇污水处理厂水污染物排放标准》(DB 11/890—2012)B级标准。这些要求为技术方案设计带来非常大的挑战,因此工程设计技术方案中应贯彻优化工艺、立体布局、分阶段实施的原则。通过论证,形成了采用MBR工艺及构(建)筑物之间层叠或镶嵌布局并分三个阶段实施的方案,以满足增大处理水量、提高出水水质、节省用地、运行中不停水的目标。
- Abstract:
- According to the requirements of the “Threeyear Action Plan for Accelerating the Construction of Wastewater Treatment and Reclaimed Water Utilization Facilities in Beijing (2016-2019)”, the expansion project of Fatou Wastewater Treatment Plant (FWTP) has been approved for the construction, which belongs to one of the 11 wastewater treatment projects of the central city of Beijing. The current treatment capacity of the FWTP is 20 000 m3/d, and the CASS process is adopted with area coverage of 1.3 hm2. The reconstruction and expansion project is required to reach the treatment capacity of 100 000 m3/d without new land acquisition or no water stoppage. The effluent water quality will be improved from the current first level B criteria of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002) to Beijing local standard grade B of Discharge Standard of Water Pollutants for Municipal Wastewater Treatment Plants(DB 11/890-2012). These requirements bring great challenges to the design of technical plan. Therefore, the principles of optimizing process, threedimensional layout and phased implementation should be implemented in the project design technical solution. Through the demonstration, a scheme was formed, which adopted the MBR process to construct the stacking or superimposing layout between structures (buildings), and was implemented them in three stages to meet the requirements of increasing the quantity of treated water, improving the effluent quality, saving land, and not stopping the water during operation.
