农村饮用水净化模式的选择

由于我国农村水源状况不同、供水设施规模不同、水质条件不同,因此采用的净水模式也不相同.粗滤和慢滤两种工艺组合对农村小型水厂建设具有推广价值,原水经过处理、消毒后可作为饮用水.起混凝作用的药剂分凝聚剂、絮凝剂和助凝剂,混凝剂的制备和投配要求十分严格,原水要与药剂充分融合.消毒是净水工艺中重要环节,凡生活饮用水必须进行消毒,消毒剂也应根据原水水质状况的不同,投放量和方法也不相同.

Selection of drinking water purification methods in rural areas

Due to the variety of water sources, scale of water supply utilities as well as water quality conditions in the rural areas, purification methods used are different. Combined with coarse filter and slow filter is viable for small water plants in rural areas, as source water is drinkable after treated and disinfected. Coagulant, flocculant and cougulant are applied for coagulation. Strict requirements are applied to the preparation and distribution. Source water and agents should be mixed thoroughly. Disinfection is the key part of purification technology. All domestic drinking water should be disinfected. Injected quantity and method of the agents should be varied according to the quality of source water.
