关于辐流式二沉池设计计算方法的探讨

Discussion on Design and Calculation Methods of Radial Flow Secondary Sedimentation Tank

摘要:

针对辐流式二沉池设计资料中存在的相关问题，从平面设计要点和竖向设计要点两方面分别对辐流式二沉池中设计流量的选定、沉淀池表面积计算、进出水口、污泥区容积计算，以及有效水深、池边水深和总池高计算等进行了探讨，并对刮（吸）泥设备和配水井的设计要点进行了相关说明。同时结合工程实践，优化平面设计参数和竖向设计参数，合理选择刮（吸）泥设备和配水井等辅助设施，能为相关技术人员提供一定的参考和借鉴意义。

Abstract:

Aiming at the relative problems existing in the design information of radial flow secondary sedimentation tank, the selection of design flow, the calculation of surface area, the calculation of inlet, outlet and sludge area volume, and the calculation of effective water depth, tank-side water depth and total tank height of the radial flow secondary sedimentation tank are discussed from two aspects of the plane design and vertical design essentials. The design essentials of sludge scraping and absorbing equipment and the design essentials of distribution well are explained. At the same time combined with the engineering practices, the plane design parameters and the vertical design parameters are optimized. The auxiliary equipment for the sludge scraping absorbing equipment and the distribution well is reasonably selected. A certain reference can be provided for the relevant technical members.
