横山桥镇农村供水管网水质模型构建及应用

Establishment and Application of Water Quality Model in Villages Water Distribution System of Hengshanqiao Town

针对农村供水管网水质现场实测的局限性和模糊性,采用EPANET构建余氯和三卤甲烷的水质模型进行实时模拟,将熵权理论应用于水质模糊评价,并以横山桥镇农村供水管网为实例展开研究,及时发现了供水管网中评价点4处水质不合要求,采取措施改善水质。结果表明该模型对确保供水安全具有一定的应用价值。

In view of the field measurement limitation and the fuzziness of water quality in water supply net- work, water quality model of residual chlorine and trihalomethanes is established by EPANET ,and water quality is real-time simulated . The entropy weight theory is applied in the fuzzy evaluation of water quali- ty. By studying the rural water supply network of Hengshanqiao town,4 points in the network were found unable to meet the water supply requirement, and measures were taken to improve the water quality. The result indicates the model has the value for ensuring the safety of drinking water supply.
