摘要
湖光污水处理厂为湛江市重要市政基础设施之一,设计近期规模2.5×10^(4)m^(3)/d,远期规模5.0×10^(4)m^(3)/d,采用AAO+AO/双侧堰周进周出辐流二沉池/深度处理工艺。双侧堰周进周出辐流二沉池作为一种特殊形式的辐流二沉池,具有表面负荷高、水力停留时间长、利于固液分离、用地节约等特点,介绍了其主要设计参数及总体布置形式、上下游衔接方式、双侧堰出水方式等,该池布水均匀、运行稳定。本工程用地面积为建设标准的77%,实现了节约土地和节省投资的目标。
Huguang sewage treatment plant is one of the importantmunicipal infrastructures of Zhanjiang city,with a design of the short-term scale of 2.5×10^(4)m^(3)/d and the long-term scale of 5.0×10^(4)m^(3)/d,using AAO+AO/double side-weir inlet and outlet circular secondary clarifier/advanced treatment.As a special form of circular secondary clarifier,double side-weir inlet and outlet circular secondary clarifier has the following features:high surface load,long hydraulic stay time,conducive to solid-liquid separation,land saving.This paper introduces themain design parameters and general layout,upstreamand downstreamcohesion,bilateral weir outletmode,etc.,the water distribution of the clarifier is uniform,and the operation is stable.The land area of this project is77%of the construction standard,which realizes the goal of land saving and investment.
