摘　　要：依据《污水处理厂污染物排放标准》(GB18918-2002年)规定,污水处理工艺方案必须具有脱氮除磷的功能。通过生物沸石与斜发沸石协同对成都市某污水处理厂进水强化预处理实验,结果表明:生物沸石对污水中的COD、TP、TN和NH3-N去除机理主要是依靠吸附和离子交换的作用;协同强化预处理使污水中的COD的去除率为76.2%、TP为90.7%、TN为84.6%、NH3-N为95.1%,同时保持污水中适宜的碳氮比,为后续生物处理提供良好条件且能够满足脱氮除磷的功能。On the basis of Sewage Treatment Plant Pollutant Discharge Standard （GB18918 - 2002） regulations, sewage treatment process should have the function of nitrogen and phosphorus removal. Through the biological zeolite and clinoptilolite collaboration on a sewage treatment plant influent of Chengdu intensive pretreatment experiments. The results showed that biological zeolite for sewage COD, TP, TN and NH3 - N removal mechanism relied mainly on the role of adsorption and ion exchange, synergistic pretreatment in the effluent COD removal rate reached 76.2 %, the removal rate of TP reached 90.7 %, the removal rate of TN reached 84.6 %, the removal rate of NH3 - N reached 95.1% . While ensuring the ratio of carbon and nitrogen in wastewater, it provided a good conditions for subsequent biological treatment and satisfy the function of nitrogen and phosphorus.
