浙江农村雨水利用技术研究

STUDY ON THE TECHNOLOGY OF RAINWATER UTILIZATION IN ZHEJIANG RURAL AREAS

浙江农村雨水排放现状基本没有收集系统,随地势、沟渠排放,排放到附近自然水体中。随着浙江五水共治及农村城镇化进程的加快,按现在的农村雨水排放形式,一方面会造成雨污合流,在暴雨期增加污水处理站的负担;另一方面随着农村道路硬化越来越普遍,农村抗涝能力也势必下降。雨水排放设计中采用国内外比较成熟的雨水利用技术,既治理了涝水,也美化农村环境,可谓一举多得。

There is no collection system for rainwater in the rural drainage of Zhejiang province, rainwater discharges into the natural water bodies nearly with terrain or ditch. As the process of ＂Five Water Work＂ and rural urbanization of Zhejiang are speeding up, current rural rainwater drainage systems would cause rainwater mixed with sewage, and increase the load of wastewater treatment station when there is heavy rain; on the other hand, with the hardened rural roads becoming more common, the rural flood-resistant ability will is bound to decrease. During the period of carrying out the ＂Five Water Work＂ and constructing the beautiful countryside, it has many advantages to design rainwater drainage by combining the advanced technology at home and abroad, for example, using the permeable pavement to discharge, plant fence, building the roof gardens and the rain gardens. These rainwater drainage systems not only govern the flood water, but also beautify the rural environment.
