摘要
沁阳市某污水处理厂提标改造工程规模为3×10^4 m^3/d。针对进水水质碳源较低、脱氮除磷效果不佳以及运行过程中调控技术的缺陷,本次提标改造采用AAO工艺处理城镇生活污水。结合污水处理厂实际情况,通过改进预处理设施、强化生物处理段和增加深度处理来提高出水水质,达到同步脱氮除磷的效果。出水水质稳定达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。
Design capacity of upgrading and reconstruction project of a wastewater treatment plant(WWTP)in Qinyang is 3×10^4 m^3/d.According to low carbon sources,ineffective nitrogen phosphorus remove and the shortcomings of control technology,AAO process is adopted in upgrading and reconstruction project.Combined with practical situation of the WWTP,the effect of simultaneous nitrogen and phosphorus removal can be achieved by improving pretreatment facilities,enhanced biological treatment section and advanced treatment.The effluent quality can reach the first grade A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918—2002).
