Urban water-supply system based on big data, and water-supply method

The invention relates to an urban water-supply system based on big data, and a water-supply method. The water-supply system comprises a water-supply high-pressure tank and a main water-supply pipelineand further comprises a circulating water pipeline and a manhole; a plurality of branch water-supply pipelines are connected to the main water-supply pipeline, water in the water-supply pipes can keep flowing through the circulating water pipeline and a circulating water recycle pool to avoid long-term staying and depositing and water quality deteriorating, the water flow and the water quality are monitored in real time through the manhole, the water flow is convenient to adjust in time, sewage is convenient to treat in time, the water-supply method can deal with various emergencies, and various ways can be adopted to guarantee water supply. 本发明涉及一种基于大数据的城市供水系统及供水方法，供水系统包括供水高压罐、主供水管道、包括循环水管道、检修井，所述主供水管道上连接若干个分支供水管道，能够利用循环水管道和循环水回收池使供水管道中的水能够保持流动，避免长期停留沉积、水质变坏，利用检修井实时监测水流量和水质，便于及时调整水流量和处理污水，本发明的供水方法能够应对多种突发情况，可以采中
