摘　　要：宁德某污水处理厂采用接触氧化和人工湿地为主的工艺,规模为1. 0×10~4m^3/d。通过对实际进水水质和原有工艺充分的调查和分析,提出了针对进水"低碳高氮磷"特点的A^2O工艺和高密度澄清池、纤维滤布滤池的强化处理工艺。该污水处理厂出水水质由《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级B标准升级为一级A标准。文章详细介绍了该工程的提标改造方案、主要构筑物的设计参数及工艺特点。The original design capacity of a wastewater treatment plant in Ningde City was 1. 0 × 10^4 m^3/d,biological contact oxidation process and constructed wetland was adopted. Through the investigation and the analysis of the actual influent quality and the original treatment process,the scheme of A^2O process and advanced treatment processes including Densadeg and cloth media filter was put forward to deal with the influent with low carbon and high nitrogen and phosphorus. The effluent quality was upgraded from the first level B to the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（ GB18918-2002）. The treatment process,the design parameters and the design experience are summarized and analyzed.
