【摘要】 通过工程实例,介绍混凝—ABR—活性污泥法组合工艺处理印染废水的效果及主要设计参数.运行结果表明CODCr、BOD5及色度的去除率分别达90%、93 4%和97 4%,最终出水水质达到《广州市污水排放标准》(DB4437 90)新改扩一级排放标准,与设计参数相符合,该组合工艺在印染废水处理中具有实用性.更多还原

【Abstract】 From the engineering instance, this paper introduces the rusult and the design of major parameters using Coagulation-ABR-Activated sludge type combined craft for the treatment of dye wastewater. The result of running indicates that the reducing rate of COD_cr,BOD₅ and chroma can reach 90%,93.4%,97.4% respectively. The final water outlet can reach the first-class wastewater emission standard for new, enlarging or reconstruction project of the emission standard of wastewater in Guangzhou （DB4437-90）, and can meet the requirement of the designing parameters. This combined technology has practical application value for the treatment of dye wastewater.更多还原
