在一些缺水地区,人们很早就发明了用水窖储水。传统的水窖制作过程非常复杂,需要很多步骤,每一个步骤都有复杂的工艺,制作工期也较长。现在,很少有人花那么多时间费那么大力气来制造这种水窖,早已开始采用“现代工艺”制作水泥窖。即挖了洞之后,在内壁和底部涂满水泥混凝土,防止渗漏,用投放消毒剂的方法来净化水质。但是,看起来费力又古老的传统水窖能自我净化水质,存放时间越
In some water-scarce regions, people have long invented water storage in cisterns. The traditional cellar production process is very complex, requires many steps, each step has a complex process, the production period is longer. Now, very few people spend so much time and energy to make such cellars so much, and have started to use “modern technology” to make cement cellars. After digging the hole, the inner wall and the bottom are covered with cement concrete to prevent leakage, and the disinfectant is used to purify the water quality. However, the seemingly laborious and ancient traditional cellar can self-purify water and store it for longer
