摘要:
针对目前城市路面径流水量水质雨水口原位监测存在的径流漫汇流、雨水口空间狭小、环境干扰大和降雨时空随机性等问题，研发了一种基于机械双稳态翻斗结构、结合紫外-可见光光谱的城市路面径流水量水质雨水口原位自动监测系统，实现了雨水口原位水量水质连续自动监测。率定及评估结果表明，该监测系统可操作性强、空间适应性高，可获取逐分钟雨水口原位水量水质数据，满足径流量为1~200 L/min的监测需求，修正后翻斗动态计量相对误差小于5%，可适用于不同类型降雨径流监测，为城市路面径流雨水口原位监测和径流污染研究提供技术参考。
Abstract:
This paper developed an automatic monitoring system for urban pavement runoff quantity and quality at gutter inlets based on a mechanical bistable tip-bucket structure combined with UV-visible light spectrum, which realized continuous automatic monitoring of runoff quantity and quality in-situ at gutter inlets, so as to solve the existing challenges such as runoff confluence, limited space of gutter inlet, significant environmental disturbance and spatio-temporal variability of rainfall. The calibration and evaluation results demonstrated that the monitoring system exhibited robust operability and high spatial adaptability. It was capable of acquiring in-situ runoff quantity and quality data from the gutter inlets every minute, meeting the monitoring requirements for runoff flows ranging from 1 L/min to 200 L/min. The relative error of the modified tipping bucket dynamic measurement was less than 5%, rendering it suitable for monitoring various types of rainfall runoff. The system provided valuable technical guidance for in-situ monitoring of urban pavement runoff at gutter inlets and controlling runoff pollution.
