一、夏季新鲜冷水与热水供应方式(参见下图): 由上图可以看出,屋面上的雨水通过落水管引入雨水贮水池(其容积最大为8m~3),再利用水泵将水从该池输送到慢滤池(砂滤床)中,水在滤池中进行机械生物净化,滤池中必须经常保持一定的水量,否则净化水所需要的微生物就会死亡。为此,在干旱季节需要从城市公共供水管网向滤池中补充一些新鲜水。过滤后的清水送入水池。
First, the summer fresh cold water and hot water supply (see below): As can be seen from the above figure, the rainwater on the roof is introduced into the rainwater storage tank (the maximum volume is 8m~3) through the downspout, and then the water is pumped from the water pump. The pool is transported to a slow filter (sand filter bed) where the water is mechanically purified in the filter tank. The filter must always maintain a certain amount of water, otherwise the microorganisms needed to purify the water will die. For this reason, in the dry season, some fresh water needs to be added to the filter pool from the public water supply network in the city. The filtered fresh water is sent to the pool.
