| 中文摘要 |
| 焦化废水中各类有机物表现出不同的挥发特征。乙苯、萘等11种物质比较容易挥发,12h空曝后其去除率约为20%-40%,它们的挥发速率常数KV与Henry常数间具有良好的线性相关关系,线性相关方程为KV=2.906×103H+0.0146,挥发作用在这类物质的去除中起着重要作用;苯酚等12种物质具有中等程度的挥发性;间苯二酚等物质其挥发作用不明显。 |
| 英文摘要 |
| A study was conducted to determine the volatile property of organics in the coke-plant wastewater under the condition of aerated stripping.The results show that there are different volatile characteristics among the organics.11 kinds of compounds such as ethylbenzene and naphthalene are more volatile.The removal rate can get to 20%-40% after an aeration of 12 hours. Their volatile rate constant Kv have a fairly good linear relation with the Henry constant(H), of which relation equation is Kv=2.906×103H+0.0146.Volatile effect plays a very important role in the removal process of these organic compounds.12 compounds like phenol have a medium volatile property.The other compounds like resorcinol have a low volatility. |
