摘要
针对点容量计算中混合区限制的要求，采用了动量积分法、经验公式法和有限差分法，分别对污水排放后可能引起的近区、过渡区和远区的污水浓度变化进行了模拟预测，并就一定的限制性条件对容量点近区、高浓度混合区及容量点远区影响范围进行了分析。在大亚湾水容量计算及污水排海规划中的应用表明，该法具有计算机时较省、精度相对较高等优点。
ased on the demand of the mixing zone limitation for allowable load in a planned discharge area (ALPDA),this paper employs the near-field plume model which can represent any pipeline marine disposal, transition-field model and the far-field two-dimension realtime model, and use them to predict the near-field transition-field and far-field concentration which are caused by waste water discharge. Thus, the method can not only control the mixing zones for the ALPDA,but also make the whole system not be influenced by the allowable loads. Practical application of the method exhibits successfully an example for the ALPDA computing and waste marine disposal in Daya Bay.
