摘　　要：传统雨水利用模式存在着占地面积大、造价高、施工周期长和资源流失等特征.雨水利用一体化技术将雨水储存、净化、清淤排泥、加压供水各项功能集于一体,实现雨水资源回收利用,符合节能环保理念.文章在分析某研发基地雨水径流水质及雨水可利用量的基础上,进行了雨水利用一体化方案设计,并将处理后的雨水用于该园区杂用水,在6～9月,雨水代替率在60％以上;经处理后的雨水水质稳定,CODCr含量为30 mg/L,SS含量为18 mg/L,符合GB/T 18920-2002《城市污水再生利用城市杂用水水质》的规定.经估算：该雨水利用系统每年可节约用水约为19915 m3,每年可节约自来水费约为8.8万元.The traditional rainwater utilization pattern has the characteristics of large floor area, high cost, long construction period, resource loss and so on. Various functions such as rainwater storage, purification, dredging mud, pressurized water supply can be got together in the integration facility of rainwater utilization, which can realize rainwater resource recycling in accordance with energy conservation and environmental protection concept. Based on the analysis of runoff rainwater quality and availability of a research and development base, a design of rainwater integration scheme is proceeded. The rainwater after treatment is used for miscellaneous water, and the rainwater replace rate is more than 60% from June to September. The quality of rainwater after treatment is stable, the CODcr content is 30 mg/L, and the SS content is 18 mg/L, meeting the ＂Urban Miscellaneous Water Quality Standard ＂ （ GB/T 18920--2002 ）. By estimating the rainwater utilization system, it can save 19915 m3 water per year and retrench water-rate 88000 Yuan per year.
