集雨水质净化方法及应用

Water Treatment Methods for Rainwater Harvesting

在对集雨水质特点进行简要分析的基础上,结合现有集雨水质净化处理的各种传统方法,重点介绍了初期雨水弃流技术、雨水粗滤处理技术、窖水慢滤净化技术、窖水终端过滤净化技术等几种集雨水质处理的新型实用技术,同时对其应用效果和特点给予分析。本文可为集雨利用地区选择集雨水质净化方法提供借鉴。

This paper briefly analyzes the water quality problems and the existing methods to improve the water quality of water cellars of rainfall catchment for rural water supply.Several newly developed easy-to-use water treatment technologies for rainwater harvesting,including initial rain-off discarded and coarse sand filter device for roof rainwater harvesting,coarse sand filtration,slow sand filter device integrated with water cellar,and multi-filtration technology before tap,are introduced and their application effects are presented,which would be helpful for selecting and applying the proper water treatment method for rainwater harvesting system.
