絮凝—γ射线辐照技术处理印染废水

摘要

Dyeing wastewater was treated by flocculation-γ-ray irradiation process. The optimum flocculation conditions and the factors affecting irradiation treatment effect were studied. The experimental results show that: The wastewater treatment effect by the flocculation-irradiation combined process is much better than that by single flocculation or radiation process; COD, TOC, TC and aniline content in the wastewater can be significantly reduced by irradiation, and the biodegradability of the wastewater can be improved; the absorbed dose rate has little effects on the wastewater treatment; With the increasing of H2O2 concentration, the COD, TOC, TIC and aniline content are all decreased.%采用絮凝—γ射线辐照技术处理印染废水,研究了最佳絮凝条件以及吸收剂量率、吸收剂量、废水pH和H2O2浓度对废水辐照处理效果的影响.实验结果表明:采用絮凝和辐照技术联用对印染废水的处理效果明显优于两个方法单独使用的效果；辐照可以显著降低废水中COD、TOC、TC和苯胺类物质的含量,并提高废水的可生化性；吸收剂量率对废水处理效果影响不大；随废水中H2O2浓度增加,COD、TOC、TIC及苯胺类含量均有所下降.
