(一)現有处理設备概况铁路给水服务的主要对象是生产用水和生活用水兩部分。目前主要是解决生产用水(尤其是供给蒸汽机车用水)。生活用水的比例较小,一般说来约佔整个供水量的10～15％左右。因此,許多处理設备都是以处理生产用水为主来考虑的。一般說来,铁路给水的特点是“水量少”“規模小”主要的設备多为取水口、一次平流沉淀池、加药混合反应池、二次平流沉淀池、或由取水口直接送入立式沉淀池。所有这些类型的处理构筑物都不能适应高浊度水的要求,完成处
(I) Overview of existing processing equipment The main objects of railway water supply services are the two parts of production water and domestic water. At present, it mainly deals with production water (especially for steam locomotives). The proportion of domestic water is relatively small, which generally accounts for about 10 to 15% of the total water supply. Therefore, many processing equipments are mainly considered for processing production water. In general, the characteristics of railway water supply are “low water volume” and “small scale”. The main equipments are mostly water intakes, an advection sedimentation tank, dosing mixed reaction tanks, secondary advection sedimentation tanks, or direct water intakes. Vertical sedimentation tank. All these types of treatment structures cannot meet the requirements of high turbidity water.
