摘要
针对天津某污水处理厂提标改造工程,通过中试试验,验证了反硝化深床滤池对污水中TN、TP及SS的去除效果,确定了药剂投加量,即碳源(乙酸钠)投加量为76 mg/L,絮凝剂(PAC)投加量为10 mg/L。详述了该工艺工程应用的设计流程、设计参数,为反硝化深床滤池在提标改造中的应用提供数据及设计参考。
For a wastewater treatment plant(WWTP)in Tianjin,removal efet of deep-bed denitrification filter on TN,TP and SS in the wastewater is verified through the pilot test,and chemical dosage is determined,the dosage of carbon source(sodium acetate)is 76 mg/L,flocculant(PAC)is 10 mg/L,and design process and parameters of the engineering application are described in detail.It provides data and design reference for the application of deep--bed denirification filter in upgrading of standard.
