摘　　要：城市杂用水在城市综合生活用水中占有重要地位,合理构建杂用水系统对缓解水资源紧张具有重要意义.海绵城市作为一种新的城市发展方式,为杂用水系统设计提供了新的思路,也提出了更高的要求.以广州科教城为例,其杂用水系统采用市政中水供水与各校区雨水调蓄利用供水并行的情况,存在功能重复、投资大、收益有限、用户接受度低等问题.对广州科教城杂用水系统进行分析与研究,对比不同水源的供水方式,探究合理的杂用水供水方式,提出基于海绵城市视角的杂用水系统设计思路,强调自然入渗、自然积存、自然渗透.以广州铁职院为模板开展杂用水系统优化设计,进行水量平衡计算,以景观水体为核心,构建集雨水汇集、贮存、利用、净化多功能为一体的设计方案,实现雨水对于杂用水需求的全覆盖.Urban miscellaneous water plays an important role in urban comprehensive domestic water consumption,and it is of great significance to construct a reasonable miscellaneous water system to alleviate water resource stress.Sponge city,as a new concept of urban development.provides a new idea for the design of miscellaneous water system,but also puts forward higher requirements.Taking Guangzhou Science and Education city as an example,its miscellaneous water system uses municipal reclaimed water to supply water in parallel with rainwater storage and utilization of each campus,which has problems such as repeated functions,large investment,limited income and low user acceptance.This paper analyzes and studies the miscellaneous water system of Guangzhou Science and Education City,compares the water supply methods of different water sources,explores the reasonable miscellaneous water supply methods,and puts forward the design idea of miscellaneous water system based on the concept of sponge city,emphasizing natural infiltration,natural accumulation and natural penetration.With Guangzhou Railway Vocational Institute as the template,the optimization design of miscellaneous water system was carried out,and the water balance calculation was carried out.With landscape water body as the core,the design scheme integrating rainwater collection,storage,utilization and purification was constructed,so as to achieve the full coverage of rainwater for miscellaneous water demand.
