摘要
随着工业园区数量的增加,园区内各类污染负荷汇集到径流雨水中,对周边水体造成严重污染,需采取措施进行治理。以湖北省荆州市某工业园区为研究对象,建立SWMM模型,围绕研究区域概化、模型参数确定和率定等方面验证模型的可靠性。根据园区地理位置建立初期雨水截流调蓄池概化模型,选用智能一体化截流提升井收集初期雨水;采用湖北省沙市暴雨强度公式和芝加哥雨型,合成不同重现期下的设计降雨过程线,并计算不同重现期下的初期雨水截流调蓄池容积。研究结果表明,各重现期下初期雨水截流效率均达到了40%以上,说明初期雨水截流调蓄池功效良好。
With the increase of industrial parks, various pollution loads are collected into the rainwater runoff. Serious pollution to the surrounding water bodies need be controlled.Taking an industrial park in Jingzhou City, Hubei Province as the researched object, the SWMM model was established. The reliability of the model was verified from the aspects of generalization of the study area, determination of model parameters and calibration. According to the geographical location of the park, a generalized model of the initial rainwater storage tank was established. The initial rainwater was collected by the intelligent integrated interception lifting well;By the rainstorm intensity formula of Shashi City, Hubei Province and Chicago rain pattern, the designed rainfall hydrographs in different return periods were synthesized, and the volume of the storage tank were calculated.The research results show that the initial rainwater interception efficiency in each return period has reached more than 40%, indicating that the initial rainwater storage tank has a good effect.
