近年来,在我国南方部分省地下水除铁一般采用淋水曝气氧化法或锰砂过滤等方法。因受设备造价高,周期长,不宜维修等条件限制,不能适应农村分散式给水的供需要求。因此,我们优选石灰碱化处理,应用淀份凝聚作用进行饮水除铁的探讨。 称取16.0克生石灰(CaO)加水至5升制成
In recent years, in some provinces in southern China groundwater iron removal methods commonly used water spray aeration oxidation or manganese sand filtration. Because of the high cost of equipment, long cycle, not suitable for maintenance conditions, can not meet the rural decentralized water supply and demand requirements. Therefore, we prefer the lime alkalization, the application of the role of starch coagulation of drinking water to explore iron. Weigh 16.0 grams of lime (CaO) water to 5 liters made
