山东农村居民生活用水量及变化系数研究

Study on residential water consumption and variation coefficient in rural of Shandong province

对山东省不同地域、不同经济发展水平的10处农村供水工程的用水量情况进行调研分析。统计结果表明:经济水平是影响农村居民生活用水量的主要因素,建议经济发达、经济发展一般和欠发达的农村居民最高日用水定额分别取70L/(人·d)、50L/(人·d)、35L/(人·d)左右。当农村供水人口规模在10万人以下时,日变化系数取值1.4～1.7;供水人口规模在10万人以上时,日变化系数取值1.1～1.4,当农村居民生活用水定额较高时日变化系数取低值。另外该文对不同规模全日制供水工程及定时供水工程的时变化系数提出取值建议。

Based on the investigation data of water consumption of water supply systems in 10 different rural areas of economic developing level , the data was calculated and studied. It can be concluded that the residential water consumption was affected by the level of economic development： the values of the most residential water consumption in rural areas are approximately 70L / （cap. d）, 50L / （cap. d） and 35 L / （cap. d） in economically developed rural areas, economically developing rural areas and economically less-developed rural areas respectively. For the population of rural areas less than 0.1 million, the coefficient of variation by days is approximately 1.4-1.7;and for the population of rural areas more than 0.1 million, the coefficient of variation by days is approximately 1.1-1.4.The coefficient of variation by hours about full-time and regular water supply is suggested in the paper.
