【摘要】 为给深层排水隧道等大口径排水系统规划和工程设计提供计算支撑,以代表性典型河涌为研究对象,根据河涌水体功能对入河污染总量控制的限值要求,通过对不同类型降雨过程中典型排口溢流污染浓度变化过程监测及典型年连续降雨研究分析,基于排水模型计算分析结果,提出广州市中心城区雨天溢流污染削减率及截流调蓄标准。更多还原

【Abstract】 In order to provide support for the planning and design of large aperture drainage system such as deep drainage tunnel,with the typical river as the research object,according to the functional requirements of river water body for the limits of total quantity of pollutants,the discharge port overflow pollution concentration variation in different types of typical rainfall process was monitored,and typical annual continuous rainfall data were researched and analyzed. Based on the calculation results of the drainage model,rainy river overflow pollution reduction rate and interception storage standard for Guangzhou City were proposed.更多还原
