Abstract:

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%.

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%。
