| 摘 要： | 综述了粉煤灰在印染废水处理中的应用。利用粉煤灰的混凝作用可使COD的去除率稳定在85%以上,色度去除率高达95%作为吸附剂可直接处理印染废水当粉煤灰与铁屑产生电化学作用时用于印染废水预处理是行之有效的粉煤灰改性后可提高吸附性,作为印染废水的助凝助沉剂,结合其它工艺,可使染料和印染废水达标排放加强理论研究,解决工程与设备问题是今后的工作方向。有27篇参考文献

| Abstract: | The application of fly ash in the treatment of printing and dyeing wastewater was reviewed with 27 references. The COD and colority of wastewater were removed by over 85% and 95% respectively with the coagulating of fly ash. Fly ash was used as a sorbent for treating dyeing and printing wastewater, and it was effective for pretreatment of dyeing and printing wastewater when electrochemical reaction occurred between fly ash and scrap iron. The modified fly ash had an improved adsorbability, and combinating with other processes the treated wastewater met the standard for release. It should be emphasized to strengthen theory research and solve the engineering and equipments problems in the future. |
