摘要
给出了对某工厂高含盐量废水出流在一天然河流形成的全盐量浓度场进行的现场测量的结果 ,并采用深度平均的紊流数学模型对测量工况下的流场和浓度场进行了计算 ,得到的计算结果与实测值具有较好的一致性 ,说明采用的数学模型对类似的问题具有较好的适用性 ,可以用于宽浅型河流岸边排放浓度场的预测。现场实测资料对于水质模型的验证和率定具有重要价值。
Field measurement of the salt concentration distribution of a natural river reach created by the wastewater of a plant is carried out and presented in this paper. The flow field and salt concentration field in this river reach is then solved using the depth averaged k-ε model. Comparison of numerical results with measured data shows that the depth averaged k-ε model is suitable for prediction of concentration field of side discharge into natural river with large width to depth ratio. The field measurement data is valuable for verification and calibration of water quality models.
