摘要
以染料废水为处理对象,对序批式活性污泥法(SBR)工艺和粉末活性炭(PAC)-SBR工艺处理染料废水进行对比试验研究,通过正交试验确定了最佳运行参数。结果表明:PAC-SBR工艺比传统SBR工艺所需的缺氧搅拌、曝气时间更短,出水水质和污泥沉降性能更好,更耐冲击负荷。PAC-SBR工艺在相对较短的周期内处理染料废水的效果更好,COD去除率达84.5%,色度去除率达88.9%。
Using the dyeing wastewater as the treating object, the contrast experiments on the SBR and PAC-SBR systems have been carried through. And through orthogonal test, the best operation parameters have been obtained. Compared with the traditional SBR system, the PAC-SBR needs shorter time in anoxic mixing and aeration, has better water quality of effluent, better sedimentation function, and better effect against impacting load. The COD removal rate is 84.5%, and chroma removal rate is 88.9%.
