| 摘 要： | 用铁屑法、瓦斯泥＋铁屑法对焦化废水进行预处理，测定了两种方法在不同处理时间、pH值、物质用量的情况下，焦化废水中化学需氧量（COD）的去除率。结果表明：在瓦斯泥中加入铁屑对焦化废水中COD的去除率明显高于瓦斯泥法。处理时间、pH对瓦斯泥＋铁屑法的去除效率影响较大，pH及在处理30min以后的处理时间对瓦斯泥法的去除效率影响较小；焦化废水中COD的去除率随加入的瓦斯泥、瓦斯泥＋铁屑量的增加而增加，但增加率却逐渐降低。

| Abstract: | Coke oven waste water is respectively pretreated by blast furnace sludge method and blast furnace sludge plus iron scrap method, the effects of pH and the quantity of materials and treatment time on the removal efficiency of COD are analyzed. The results indicate that blast furnace sludge plus iron scrap method is superior to blast furnace sludge method .The treatment time and pH can greatly affect on the removal efficiency of COD using blast furnace sludge plus iron scrap method. The treatment time after 30 minutes and pH have no remarkable effects the removal efficiency of COD using blast furnace sludge method. The removal efficiency of COD increases with the increase of blast furnace sludge and iron scrap, but the increase rate decreases gradually. |
