| 中文摘要 |
| 利用H2SO4-HCl混酸溶解轧钢废钢渣的溶出液作原料,制成一种新型无机高分子絮凝剂聚合氯硫酸铁(简称PFCS).试验了它的絮凝性能,并与聚合硫酸铁(简称PFS)的絮凝效果进行了比较。实验结果表明:PFCS在pH=6-9的范围内具有良好的絮凝去浊性能;絮凝条件相同,将浊度为425度的黄河水样处理至5度以下,PFCS的投用量仅需10mg/L,而PFS的投用量至少需25mg/L.PFCS的絮凝沉降效果较PFS要好。 |
| 英文摘要 |
| New inorganic polymeric flocculant poly sulfuric chloride ferriferous(PFCS) has been prepared by using dissolving rolling waste steel residue with mixing acid H2SO4-HCl as raw material.The flocculating effect of PFCS has been tested and compared with that of poly sulfuric ferriferous(PFS).The experimental results showed that the flocculating effect and removing tubidity are very good in pH range of 6-9.The quantity of PFCS was only 10 mg/L when Yellow River water was treated from 425 tubidity degree to below 5 degree,but the least quantity of PFS was 25 ml/L at the same flocculating conditions.The flocculating effect of PFCS is much better than that of PFS at the same conditions. |
