摘要
针对小城镇给水规划中用水量确定不舍理的现象，对10个区域典型小城镇群1998-2004年用水量进行了实地调查,统计结果表明小城镇生活用水日变化系数宜取1．4-2．5．对于室内设有给水排水卫生器具，但无淋浴设备的居民住宅，时变化系数建议取值为2．1-2．6；设有给水排水卫生器具井有淋浴设备的住宅，建议取值1，4-1．8；设有给水排水卫生器具井有淋浴设备和集中热水供应的住宅，建议取值1.3-1.5，居民住宅室内给排水卫生设施条件不完善的取高值，居民住宅室内给排水卫生设施条件完善的取低值。
For correcting water demand in water supply planning of towns, based on the actual investigation data of water consumption of typical town groups in 10 areas from 1998 to 2004, the result shows that daily variation coefficient of domestic water consumption about towns is 1.4 - 2.5. For the dwelling houses which are equipped with the sanitary establishment but without shower, 2.1 - 2.6 is suggested. For the houses which are equipped with the sanitary and shower establishment, 1.4 - 1.8 is suggested. For the houses which are equipped with the sanitary, shower and centralized hot water supply establishment, 1.3 - 1.5 is suggested. The coefficient can be higher when the sanitary establishment is not perfect, and it can be lower when the sanitary establishment is perfect.
