目前,水质混凝沉淀方法颇多。多数采用明矾、羟基氯化铝等做混凝剂。但都存有沉淀慢、干扰因素多、难掌握用量等缺点,不适合部队野战条件下应用。为探讨改进明矾在水质混凝上的应用,加速混凝沉淀,缩短水质净化时间,我们用芋头作明矾的助凝剂进行水质净化试验,收到较好效果,现将方法介绍如下。试验方法 1.试验水样:我们采用2克/升的混浊水样做试验,即在1升水中加入2克土,搅
At present, there are many methods of water quality coagulation and sedimentation. The majority of alum, hydroxy aluminum chloride coagulant. However, there are slow sedimentation, interference factors, difficult to grasp the amount and other shortcomings, is not suitable for military applications field conditions. In order to explore the application of alum in improving water coagulation, speed up the coagulation and sedimentation and shorten the water purification time, we use taro as coagulant for alum to purify the water quality and receive good results. The methods are introduced as follows. Test methods 1. Test water samples: We use 2 g / l turbid water samples for testing, that is, 1 liter of water by adding 2 grams of soil, stirring
