摘要
采用淀粉、丙烯酰胺等为主要原料制取了天然高分子有机絮凝剂 ST- AM,并重点研究 ST- AM与无机混凝剂Fe SO4 · 7H2 O复配使用对染料废水的处理 .实验结果表明 :ST- AM与 Fe SO4 · 7H2 O复配使用对染料废水具有优良的脱色性能 ,色度去除率达 70 %～ 99.9% ,CODcr去除率达 5 2 .8%～ 6 5 .6 % ,并且絮体的沉降速度加快 .
An organic high polymer flocculent ST AM is prepared with starch, acylamide, etc. The treatment of dye wastewater by FeSO 4·7H 2O matching with ST AM is studied. The result shows that the effect of FeSO 4·7H 2O matching with ST AM is excellent in treating dye waste water. The removal rate of color is above 70%,the removal rate of CODcr is above 52.8%, and the sedimentation is improved.The method provides a potential use in industry.
