摘要
采用铁屑过滤-SBR工艺对印染废水进行了处理研究.当进水COD为1000-1600mg/L,色度为200-800倍,BOD5在200-400mg/L时,COD去除率可达85%,BOD5去除率和脱色率均在90%以上,出水达到排放标准.该工艺具有投资少、运行费用低、处理效果稳定等特点。
The experiments of treating dyeing wastewater have been finished using filtration with iron filings and Sequencing Batch Reactor (SBR) method.The removal efficiency of COD reached 85%,BOD 5 and colour over 90% when influent COD equaling 1000-1600mg/L,BOD 5 200-400mg/L and colour 200-800 times.The final effluent quality has met discharge standards.This process is less cast in construction and running.It is suitable for the treatment of the wastewater coming from middle or smaller dyeing factory.
