| 中文摘要 |
| 大量的实验及环境监测数据表明,烟煤煤气站发生护煤气洗涤废水长期完全封闭循环运行后,废水中以挥发酚为主的污染物浓度不会无限增长,存在着动态平衡。在平衡范围内,挥发酚浓度为1300-2000mg/L,氰化物为4-20mg/L,硫化物为35-70mg/L.研究结果表明,对发生炉煤气洗涤废水采取以预处理除去废水中悬浮物和焦油的封闭循环回用的治理技术路线是完全可行的。 |
| 英文摘要 |
| A large amount of experiments and monitering data showed that after circulation of coal gas washwater, the concentration of pollutants (mainly valatile phenol) does not increase unlimitedly, but reaches a dynamic equilibrium. The concentration of phenol is 1300-2000 mg/L, cyanide is 4-20 mg/L,sulfide is 35-70 mg/L at the range of equilibrium.The result showed that it is completely feasible to use the routine technological treatment of closed-looped circulation of pretreatment of coal gas washwater removing suspended solids and tar. |
