深圳市某产业园区雨水收集利用系统设计

Design of Rainwater Harvesting and Utilization System in an Industrial Park in Shenzhen

文章通过对雨水收集系统的设计、实施和效益进行研究,旨在探讨其在可持续城市发展和碳减排方面的作用。通过对深圳水情的分析评估了深圳市某产业园区内设置雨水收集回用系统的可行性,根据《城镇雨水调蓄工程技术规范》(GB 51174—2017)开展该项目的雨水收集利用工程规模及年用雨量设计并介绍了系统课可选用的主要部件,并对雨水收集系统的经济效益进行评估。计算结果表明,每年能够回收利用的雨水总量约为9 386.012 m^(3),投资该雨水收集系统在第12年即可回收全部投资。得出该工程建设雨水回收利用系统具有良好的经济效益,并对于园区雨水收集利用系统的后续改进提升进行了探索研究,为进一步完善和推广系统提出建议。

This paper examines the design,implementation and benefits of rainwater harvesting systems to explore their role in sustainable urban development and carbon reduction.By analyzing the water situation in Shenzhen,the feasibility of setting up a rainwater collection and reuse system in an industrial park in Shenzhen is evaluated.Then,according to the Technical Code for Urban Stormwater Detention and Retention Engineering(GB 51174-2017),and the main components of the system course are introduced.And the economic benefit of the rainwater collection system is evaluated.The calculation results show that the total amount of rainwater that can be recycled and reused each year is about 9386.012 m^(3).Investing in this rainwater collection system can fully recover the investment in the 12th year.It is concluded that the construction of a rainwater recycling and utilization system in this project has good economic benefits.The follow-up improvement of the rainwater collection and utilization system in the park is explored and studied,and suggestions are put forward for further improvement and promotion of the system.
