【Abstract】 Rainwater is often collected into cisterns (pits or tanks) for household using as drinking water source in the rural areas of the northwest and the southeast coast in China, where no enough fresh water resource is available. However, the total number of bacteria and coliforms in the cisterns water was higher than the standard of that in drinking water. In order to ensure the safety for drinking, the effectiveness, conditions of treatment and cost for such disinfection methods compared with solar radiation, ultraviolet (UV), chloridation, micro filteration and KDF were studied in 10 households in Cixi of Zhejiang Province and Weiyuan of Gansu Provinces. respectively. The micro filteration is more compatible for bacteria removal in the tanks, while chloridation more for disinfection in the underground pits.更多还原
