摘要
介绍了“化学絮凝＋ABR＋氧化沟”工艺在草浆造纸废水处理工程中的应用。工程运行结果表明：该系统处理效果好、性能稳定、维护管理方便，出水 pH为7.0-7.2，COD在30.5-45 mg/L之间，SS在15-25 mg/L之间，COD和SS的平均去除率达到96%以上，出水水质达到 GB3544-2008《制浆造纸工业水污染物排放标准》要求，通过制浆回收和废水循环利用，降低了运行成本，带来很好的环境效益和经济效益。
Thecombinationprocessof chemical flocculation, ABR and oxidation ditch used to treat wastewater from straw pulp papermaking was introduced. The running results of the actual operation showthat,thesystemis high-efficiency and convenient;pH,COD,SS of the effluentare7.0-7.2,30.5-45mg/L and 15-25mg/L. The effluent qualitycan meetthe requirements of“Discharge Standard of Water Pollutants for Pulp and Paper Industry”（ GB3544-2008）.Throughrecycling the pulp andwastewater,theoperation cost canbe reduced, whichwillbringgood environmental and economical benefits.
