摘　　要：采用混凝沉淀-活性污泥A/O-混凝沉淀组合工艺对某大型印染废水处理厂进行提标改造研究,考察了不同停留时间(HRT)、工艺组合及不同投加药剂条件下,集中式印染废水处理厂废水CODCr的去除效果。结果表明:当进水CODCr质量浓度为915~1300 mg/L时,经新工艺处理后出水CODCr平均质量浓度为82.9 mg/L,符合提标改造要求。A combined process of coagulation sedimentation-activated sludge A/O-coagulation sedimentation is used to upgrade and transform a large-scale printing and dyeing wastewater treatment plant.The removal efficiency of CODCr from wastewater in a centralized printing and dyeing wastewater treatment plant is investi⁃gated under different retention time(HRT),process combinations,and different dosing conditions.The experi⁃mental results show that under the conditions of 915-1300 mg/L influent CODCr,the average concentration of CODCr after treatment is 82.9 mg/L,which meets the requirements of upgrading and transformation.
