| 中文摘要 |
| 为了探讨从煤矸石中浸出铝铁的原理和工艺,利用透射电镜、红外光谱和X-射线衍射分析技术对PAFC的结构进行了表征,试验了PAFC处理实际工业废水的效果。结果表明,用煤矸石制取PAFC是可行的;制备出的PAFC是聚合铝铁的复合产物;用PAFC处理煤矿矿井废水及油田含油污水,PAFC投量为40mg/L时,COD去除率,SS的去除率以及除油率分别为80%,90%和90%左右。 |
| 英文摘要 |
| Ployaluminum ferric chloride(PAFC),a new type of inorganic flocculant,was prepared by gangue.a kind of waste from coal-mine,and hydrochloric acid as raw materials.The structure of PAFC was studied by transmission electron microscope(TEM),IR spectroscopy and X-ray diffraction.The effect of PAFC in industrial wastewater treatment was tested.The experimental results showed that it is feasible to prepare PAFC from ganguej PAFC produced is the compound of polyaluminum chloride and polyferric chloride.After the wastewaters from coal-mine and oilfield were treated with PAFC in 40 mg/L,the removal ratios of COD,SS and oil are about 0.8%,90% and 90% respectively. |
