【摘要】 通过一系列实验，选出一种高效、无毒的絮凝剂——氯化铁，并确定了最适宜的回收工艺条件：原料液等电点的ｐＨ值为３５，它与１ ｍ ｏｌ／Ｌ氯化铁溶液的适宜体积比约为（８０～１３０）∶１。同时讨论了温度对絮凝效果的影响。通过与自然沉降法进行比较，说明本方法对粗蛋白的回收效果显著。更多还原

【Abstract】 Through a series of experiments,the ferric chloride —— a high efficiency and non toxic flocculant was selected and the optimal process conditions of recovery were chosen:the pH value of the waste water on its isoelectric point is 3.5,and the volume ratio of the waste water to l mol/L FeCl 3 is (80～130)∶1.The flocculating effect influenced by temperature was also discussed.Compared with the natural settling,this method has a much better recovery effect.更多还原
