| 摘 要： | 分别以硅藻土、硅藻土与氯化铝、硅藻土与氯化铁为吸附剂,考察并对比了3种吸附体系对焦化废水的处理效果。结果表明,硅藻土与铝盐和铁盐等无机絮凝剂复配后,对焦化废水的处理效果显著提高,其与氯化铝复配的吸附效果要优于与氯化铁复配。硅藻土与氯化铝复配时,当m(氯化铝)/m(硅藻土)为1时,其对焦化废水的处理效果最佳,化学需氧量、浊度、色度和UV254去除率分别为40.14%,38.82%,37.81%,11.56%;与氯化铁复配时,当m(氯化铁)/m(硅藻土)为1时,其对焦化废水的处理效果最佳,化学需氧量、浊度、色度和UV254去除率分别为36.01%,33.45%,19.35%,5.87%。 |

| Abstract: | The effects of diatomite, diatomite with aluminum chloride, and diatomite with ferric chloride on coking wastewater treatment were studied and compared. The results showed that after compounding diatomite with aluminum salt or ferric salt, their treatment effect was improved significantly, and the effect of diatomite with aluminum chloride was better than that diatomite with ferric chloride. When the mass ratio of aluminum chloride to diatomite was 1, the removal rates of COD, turbidity, chroma and UV 254 were 40.14%,38.82%,37.81% and 11.56% respectively. When the mass ratio of aluminum ferric to diatomite was 1, the removal rates of COD, turbid- ity,chroma and UV 254 were 36.01% ,33.45% , 19.35% and 5.87% respectively. |
