白水中主要成分:一是固悬物如纤维、填料;一是溶解性盐基如松香胶、硫酸铝等。由于固悬物的存在,不能直接用去洗网洗毛布。必须除去悬浮物(SS)后才能回用。天津使用回收装置有两类:即斜板沉淀法和气浮法。现在已有93％机台有回收设备,生产证明效果显着。单位水耗降低50％以上,平均SS去除率90～92％,COD去除率75％;平 The main components of white water: First, solid suspended solids such as fiber, filler; First, soluble salts such as rosin gum, aluminum sulfate. Due to the presence of solid suspended solids can not be directly used to wash the net wash wool. Must remove the suspended solids (SS) before reuse. There are two types of recycling facilities in Tianjin: that is, inclined plate precipitation and flotation method. Now 93% of the machines have recycling equipment, the production proved effective. Unit water consumption reduced by 50% or more, the average removal rate of SS 90 ~ 92%, COD removal rate of 75%;
