摘　　要：广州市黄埔区某水质净化厂二期工程需要在不规则的用地形状、复杂的场地周边环境、较低的建设用地指标及地上高水平建设开发的预期下,实现规模为5万m^(3)/d地下式污水处理厂的设计工作。工艺设计上通过采用“厌氧-缺氧-好氧+膜生物反应器(AAO+MBR)”工艺提升节地效率;结构设计上通过处理单元构筑物的共壁、错层实现“地尽其用”;平面设计上通过优化池体上部建(构)筑物布局、设施设备设置、交通物流规划、管线综合排布来提高操作空间的使用率。本工程项目用地负荷率比同类项目提高了36%,工程直接费用的建设单位成本低于广州市同等规模同类型项目8.5%的情况下,实现了工程设计目标,为同类项目的设计提供了良好示范。The second phase of a water purification plant in Huangpu District,Guangzhou City needs to realize the design of an underground wastewater treatment plant(WWTP)with a scale of 50000 m^(3)/d under the expectation of irregular land shape,complex surrounding environment,low construction land index and high-level above-ground construction and development.In the process design,the"anaerobic-anoxic-oxic+membrane bio-reactor(AAO+MBR)"is adopted to improve the efficiency of land saving.In structural design,the common wall and staggered floor of the unit structures are treated to make the best use of the land.In the graphic design,the utilization rate of the operation space is improved by optimizing the layout of the upper buildings,facilities and equipment,transportation and logistics planning.The land load rate of this project is increased by 36%compared with similar projects,and the cost of direct project construction is lower than 8.5%of the same scale and projects of the similar type in Guangzhou City,which achieves the engineering design target and provides a good demonstration for the design of similar projects.
