| 摘 要： | 无机混凝剂硫酸铝，硫酸铁分别与有机絮凝剂聚丙烯酰胺配合使用处理糖精钠废水，并进行处理效果比较，结果表明，硫酸铝和聚丙烯酰胺配合使用的处理效果好，当硫酸铝投加量为３．２ｇ／Ｌ，聚丙烯酰胺投加量为８ｍｇ／Ｌ，ｐＨ为６时，废水ＣＯＤｃｒ可从４１３００ｍｇ／Ｌ减小到１６８００ｍｇ／Ｌ，去除率达６１％；Ｃｕ＾２＋浓度从３２．７３ｍｇ／Ｌ降至３．１７ｍｇ／Ｌ，去除率达９０．３％，且提高了ＢＯＤ５／ＣＯＤｃｒ值

| Abstract: | Wastewater containing saccharin sodium was treated by coagulation with inorganic coagulants, Al2 (SO4)3, Fe2 (SO4) 3, and in combination with organic coagulant PAM. The results showed that the treatment efficiency was higher by co-coagulant of Ah(SO4)3 and PAM than that by Fe2(SO4)3 and PAM. When the amount of Al2(SO4) 3 and PAM used were 3.2g/L and 8mg/L,and under the condition of pH6, CODcr in wastewater were reduced from 41 300mg/L to 16800mg/L, and concentration of Cu2+ ion was decreased from 32.73mg/L to 3.17mg/L. Their removal efficiencies were up to 61% and 90.3% respectively. The value of BOD5/CODcr was increased, and biode-gradation was improved. |
