广州市住宅小区管道直饮水项目现状调查与分析

Investigation and Analysis for Current Status of Pipe Fine Drinking Water Project for Residential Areas in Guangzhou

通过调查问卷对广州市43个住宅小区管道直饮水项目的设计情况做了调查研究。数据表明,新颁布的《管道直饮水系统技术规程》(CJJ110—2006)在引导工程的科学设计方面发挥了较大作用。但调查中还发现,该规程与广州市的实际情况还存在一些出入,如最高日直饮水定额q0标准偏高、用水高峰时段延续时间内的用水量占最大时用水量的比例系数α偏低等,还有待于进一步完善。

The design of pipe fine drinking water project for 43 residential areas in Guangzhou was investigated by the questionnaires. The data show that the Technical Specification of Pipe System for Fine Drinking Water （CJJ 110-2006） exerts a greater role in guiding the scientific engineering design. But the investigation finds that there is some discrepancy between the specification and the urban practical situation. For example, the maximum daily drinking water ration （ qo ） is higher and the proportional parameter of water consumption during water consumption peak to maximum hourly water consumption （α） is lower, so the specification will be further perfected.
