| 摘 要： | 现有的城市供水管网水质预测模型仅针对单一水质组分,不足以全面反映管网水的水质状况.为此,以天津市某高校的校园管网为研究对象,在结合水力分析的基础上,同时对余氯和浊度进行预测和模拟建模.在模型的求解上,经对多元回归、人工神经网络和支持向量机进行详细的分析后,选用了较为成熟的BP算法.结果表明,模型预测的相对误差平均为20%左右,能满足实际应用的要求. |

| Abstract: | The existing forecast models for water quality in water supply network are only for a single water quality parameter,which can not entirely reflect the water quality status of the whole water supply network.To overcome the above deficiency,taking a water supply network of an university in Tianjin as study object,a new mathematical model for simultaneous forecast and simulation of residual chlorine and turbidity was developed on the basis of the hydraulic analysis.For model solution,after a detailed analysis... |
