摘要 基于目前城市绿地采用饮用水地面喷灌技术,造成绿地喷灌用水量不均匀且极大地浪费饮用水资源等问题,探讨了应用于城市绿地微灌的再生水处理工艺、处理后再生利用的水质标准及其微灌系统设计技术。通过对再生水绿地微灌系统的设计参数、首部枢纽、管网布置、灌水器的喷洒方式及控制系统等的设计介绍,归纳了城市绿地再生水微灌系统的一般规划设计方法,并对再生水微灌技术应用于城市绿地的经济与社会效益进行了初步分析。经探讨分析认为,再生水微灌技术在城市污水再生利用、降低水环境负荷和推广先进的绿地灌溉节水技术等方面找到了新的结合点,并且对污(废)水再生利用、保护水环境、节约水资源、城市生态景观绿化等技术结合方面的研究与应用起到了较大的推动作用。 Concerning the problem of non-uniform irrigation, huge extravagation of water resource, and using drinking water as ground water irrigation for urban grassland, the application of the regeneration water technology, reuse of treated water quality standards, and micro-irrigation system design technology are discussed. In addition, design parameters, key water pivot, piping network and sprinkling patterns of ground water irrigation techniques of urban grassland are summarized. Finally, a general design procedure is presented. The technology can be used for city sewage regeneration, reducing the environment load and promoting the green space irrigation.
