摘　　要：本研究拟通过聚合氯化铁强化生物絮凝,去除原水中部分总磷(TP)与化学需氧量(COD).研究在污水厂中采用实际废水进行,于中试装置中投加聚合氯化铁絮凝剂,以TP及COD为控制指标水质符合典型的短程硝化-厌氧氨氧化工艺的需求.综合批次试验及中试运行的长期试验结果表明,在中试装置中投加30 mg/L聚合氯化铁时对生活污水处理效果最好,对总磷去除率达到83%,为总磷的排放量达标提供了基础.COD去除率达到70%,为后续短程硝化-厌氧氨氧化工艺的运行提供了前提条件.This study intends to enhance bioflocculation by polymeric ferric chloride to remove part of total phosphorus(TP)and chemical oxygen demand(COD)from raw water.The actual wastewater was used in the wastewater treatment plant.Polyferric ferric chloride flocculant was added to the demonstration plant.The water quality with TP and COD as control indicators met the requirements of typical partial nitrification-anammox process.Comprehensive batch test and long-term test results of demonstration plant show that adding 30 mg/L polymeric ferric chloride in demonstration plant has the best effect on domestic sewage treatment,and the removal rate of total phosphorus reaches 83%,which provides a basis for the discharge of total phosphorus to meet the standard.The removal rate of COD reached 70%,which provided the precondition for the operation of the subsequent partial nitrification-Anammox process.
