树状管网对饮用水水质影响研究

Study on the influence of tree pipe network to the quality of drinking water

目的了解树状管网对饮用水水质的影响程度。方法对管径200mm以下管网进行配额抽样,研究不同材质、管龄和输送距离对饮用水水质的影响。结果和讨论研究的水质指标都不同程度地受到树状管网的材质、管龄和输送距离影响。结论要加快水网改造进度,尽量减少树状管网的使用范围。

objective： To study influence from tree pipe network to drinking water. Methods： Quota sampling the pipe network with a pipe diameter under 200mm , study on the influences from different pipe material, pipe age and transport distant. Results and discussions： Different pipe material, pipe age and transport distant of tree pipe network of- fered various degrees of influence to the studied water-quality indexes. Conclusion： We should speed up water network reconstruction and minimize the applying of tree pipe network.
