摘　　要：针对劣质水贫困地区解决饮水安全存在的集雨水窖材质对水质影响研究薄弱的问题,通过对不同材质的水泥砂浆抹面水窖、固化土水窖、橡塑水窖3种水窖贮存雨水的浊度、pH值、COD等指标的变化过程进行分析,研究了雨水集蓄生活型水窖水水质变化趋势。结果表明:贮存雨水初期水质各指标波动较大水质难确定,而后在长期贮存中水质各指标逐渐趋于稳定平衡。浊度、COD、微生物指标之间互相关,收集低浊度的雨水对水的自净、微生物生长的限制及消毒有重要作用,建议应加强集流面管理,或通过过滤池实施应用,将浊度降低在初期。不同材质水窖对雨水水质净化各有优劣,基本能满足饮用水标准,实际采用时应因地制宜。Be aimed at safety of drinking water in poor-quality water poverty-stricken areas existing weak study on cellar material impact on water quality issues,the different materials of cement mortar plastering cellar、solidified soil cellar and rubber-plastic cellar were conducted to study the trends of water quality of rainwater harvesting life-form cellar,and the changes of the turbidity,pH value,COD and other indicators of storage rainwater have been analyzed. The results indicated that storage rainwater fluctuated greatly in early time,while in long-term storage period,water quality indexes become stable equilibrium gradually. Turbidity,COD,microbiology indicators correlated each other,low turbidity of pre-collection of rainwater had played significance role on the water purification,limiting the growth of micro-organisms and disinfection,thus it was necessary to strengthen catchment area management and to implement pool filters,etc.,it can reduce turbidity in the initial stage. Different materials cellars had their own advantages and disadvantages,and all can basically meet the standards of drinking water,so practical application should be adapted to local conditions.
