摘　　要：为消除厂外管网溢流污染,江苏某污水处理厂面临着处理规模从3.0×10^(4)m^(3)/d提升至4.0×10^(4)m^(3)/d的扩容需求,同时需采用工期短、占地小、投资省和运营成本低的解决方案。针对上述需求,采用了高浓度复合粉末载体生物流化床(HPB)工艺对该厂进行原位扩容改造。改造结果表明,HPB技术大幅提高了处理水量(稳定在4.0×10^(4)m^(3)/d以上),出水主要指标满足COD≤30 mg/L、NH3-N≤1.5 mg/L、TN≤10 mg/L、TP≤0.3 mg/L的排放标准;在不增加占地的情况下,改造总工期仅85d,且全程不停水。与改造前相比,碳源投加量减少50 mg/L,运行成本节省约0.09元/m^(3)。In order to eliminate the overflow pollution of the pipe network outside the plant in Jiangsu Province,a wastewater treatment plant(WWTP)is facing the requirements of promoting the treatment capacity from 3.0×10^(4) m^(3)/d to 4.0×10^(4) m^(3)/d,and solutions with short construction period,small land occupation,low investment and low operation cost.In view of the above requirements,high concentration powder carrier bio-fluidized bed(HPB)technology is adopted to carry out in-situ expansion and reconstruction of the WWTP.The transformation results show that the HPB technology has greatly increased the wastewater treatment capacity as stably above 4.0×10^(4) m^(3)/d,the main effluent quality indexes meet the discharge standards of COD≤30 mg/L,NH_3-N≤1.5 mg/L,TN≤10 mg/L,and TP≤0.3 mg/L,respectively.Without increasing land occupation and without water suspension throughout the whole process,the total construction period of the reconstruction is only 85 days.Compared with pre-renovation,the dosage of carbon source is reduced by 50 mg/L,and the operating cost is saved by 0.09 yuan/m^(3).
