EMPIRICAL RESEARCH OF WATER QUALITY AND QUANTITY CONTROL EFFECT OF SPONGE CITY CONSTRUCTION: A CASE STUDY OF HEBI PILOT AREA
-
摘要: 首批国家海绵城市试点建设已经完成,有关海绵城市规划与模型模拟的研究也层出不穷,但是对于海绵建设区开展持续监测并进行深入分析的研究较为缺乏,而对于海绵城市实际建设区的水质水量研究是规划建设理论与实践效果差别的唯一检测器,是优化未来海绵城市规划和建设的关键。以河南省鹤壁市国家海绵城市建设试点区为研究对象,开展试点区地表水体与雨水管网的水质水量多年持续监测研究,分析海绵城市建设对地表水主要水质指标和雨水年径流总量控制率的实践作用效果。采用人工监测与设备在线监测相结合的方式,于2015-08—2018-09在海绵城市试点区地表水体10个采样点进行了16次人工采样,共计获得109个地表水样并测定了常规水质。利用试点区内20个雨水管道出口处的流量在线监测设备获得2018-01—12的分钟级流量数据。结果表明:研究区域内波动较大的水质指标为NH3-N、TN和DO,波动较小的为pH。与海绵城市建设前相比,研究区域的地表水系水质得到改善,试点区该年度的雨水径流总量控制率达到85.7%,满足规划建设要求指标70%。但当实际场次降雨量低于设计雨量23 mm时,仍有雨水外排。不同地块的径流控制率差异明显。以上结果丰富了海绵城市建设的实践研究,可为优化海绵城市的规划与设计建设提供参考。Abstract: After the first batch of pilot cities construction completed, studies on sponge city planning and simulation increased obliviously. However, studies on continuous monitoring and in-depth analysis of sponge construction were still scarce, which were just the key to optimize the future planning and construction of sponge city. This study selected Hebi in Henan Province as the research area to analyze the characteristics of water quality and runoff reduction rate, before and after the sponge city construction. The purpose was to evaluate the effectiveness of sponge city construction on surface water quality and quantity. Manual monitoring and auto-detecting measures were used to monitor water quality and quantity in study area. From August in 2015 to September in 2018, 10 sample sites were monitored by 16 batches and 109 samples were finally analyzed. Meanwhile, flow data collected by the flowmeters of 20 rainwater discharge pipelines in 2018 were analyzed. The results were as follows: three water quality indexes, NH3-N,TN and DO had higher variation scopes, while pH had a lower variation scope. With the construction of sponge city, water quality had been improved. The runoff reduction rate of 2018 was as high as 85.7%, meeting the expected requirements. However, rainwater was discharged into pipelines when rainfall depth was less than 23 mm. The runoff reduction rate of different parts in study area was significantly different. This study enriched the practical data for sponge city and provided support for its construction and maintenance.
