宾馆酒店是水资源消费大户。通过对天津市的 11家宾馆酒店进行抽样调查, 分析其用水结构并对其中 6 家宾 馆的水平衡测试报告进行了数据分析。通过主成分分析和相关性分析两种方法找出宾馆酒店的主要用水影响因素, 运用数理统计方法中的简单平均法、 加权平均法、 二次平均法和概率测算法, 计算得到不同水平下宾馆酒店的基础用 水定额。考虑到不同类型宾馆酒店的用水差异, 计算得到不同类型宾馆酒店的调节系数。为保证用水定额管理的有 效实施, 且使各宾馆酒店的满足率达到 70%, 建议当前宾馆酒店行业的用水定额值取 500 L/( 床# d), 调节系数取 013~ 1 1 6。与现行用水定额进行比较, 可以看出编制的用水定额值具有合理性、 先进性并在全国处于领先水平。

Water resources consumption of hotels is very large. Based on the sample investigation of 11 hotels in Tianjin, the structure of water utilization and water balance test reports of 6 hotels were analyzed. The main factors affecting water con2 sumption in hotels were identified through the principal component analysis and correlation analysis. T he basal water use quotas of hotels with different levels were calculated using the statistical analysis methods, including simple average method, weighted 2 average method, secondary average method, and probabilistic evaluation method. According to the differences of water consump2 tion in different types of hotels, the accommodation coefficients for different types of hotels were introduced and obtained from scientific calculations. In order to guarantee the effective implementation of water quota management and achieve the satisfaction rate of 70% for each hotel, the basal water use quota was suggested as 500 L/( bed# d) for hotels in Tianjin, and the accommo2 dation coefficient was suggested between 0. 3 and 1. 6. Compared with the existing water use quotas, the suggested water use quota is rational and advanced.
