应用新型悬浮陶粒流化床工艺处理城镇生活污水处理厂尾水进行了中试,结果表明,在进水体积流量0.88m3/h、悬浮陶粒流化床滤速7m/h、石英砂柱滤速7m/h、气水体积比1∶1工况下,进水NH4+-N的质量浓度4.92～5.92mg/L时,砂滤出水NH4+-N的质量浓度＜1.0 mg/L;通过化学强化除磷和高锰酸钾预氧化进一步去除TP和COD,在悬浮陶粒流化床前投加PAC 40 mg/L,进水TP的质量浓度达1.13 mg/L时,砂滤出水TP的质量浓度＜0.3 mg/L,TP去除率达80.53％,在流化床前投加PAC后TP的去除率比后投加平均高8.79个百分点;投加3 mg/L高锰酸钾预氧化后,进水COD的28.50～38.71 mg/L时,砂滤出水COD为13.88～21.49 mg/L,平均去除率46.97％,比没有投加时平均去除率提高了14.60个百分点.上述实验出水水质指标达到GB 3838-2002的Ⅳ类水乃至Ⅲ类水标准.“,”A new suspension ceramsite fluidized bed was employed for treating tail water from urban sewage treatment plant.The results showed that with the volume flow rate of 0.88 m3/h,suspended ceramsite fluidized bed filtration rate of 7 m/h,sand filter filtration rate of 7 m/h,gas water volumeratio being 1∶1,when the mass concentration of NH4+-N was 4.92～5.92 mg/L,sand filter effluent mass concentration of NH4+-N ＜1.0 mg/L;the TP and COD need to chemically enhanced phosphorus removal and potassium permanganate preoxidation to achieve a better standard;adding PAC 40 mg/L before the suspension ceramsite fluidized bed,the mass concentration of TP was 1.13 mg/L,the sand filter effluent mass concentration ofTP＜0.3 mg/L,the removal rate was 80.53％,and adding PAC before the suspension ceramsite fiuidized bed TP removal average rate is 8.79％ higher than after adding;adding 3 mg/L potassium permanganate preoxidation,when the COD was 28.50～38.71 mg/L,the sand filter effluent COD was 13.88～21.49 mg/L,the average removal rate of 46.97％,compared with not adding the potassium permanganate,the average removal rate increased by 14.60％.Through the above measures,sand filter effluent could meet the fourth or the third class of GB 3838-2002 standard.
