| 摘 要： | 采用复合滤池-人工湿地组合工艺处理城市高污染水,考察了组合工艺对污染物的去除效果及稳定性的影响。结果表明,有机物的降解和硝化主要在滤池中完成,氮、磷则通过人工湿地进一步去除。温度的季节性变化对磷的去除效果有少许影响,碳源不足限制了脱氮效果,组合工艺对污染物的处理效果稳定,出水中COD、TP、NH4+-N、TN平均质量浓度分别为16.39、0.38、1.44、16.38 mg/L,出水水质可达到城市杂用水水质标准。

| Abstract: | The combined process of composite biofilter and artificial wetland were used to treat the urban high polluted water,and the contaminant removal efficiency and the stability of the combined process were investigated.The results showed that the organic substance had been made degradation and nitration in the composite biofilter,and nitrogen and phosphorus were further removed in the constructed wetland.Seasonal variation of temperature showed some influences on the removal efficiency of phosphorus.Insufficient carbon source restricted the nitrogen removal.The combined process had stable contaminant removal efficiency.The average concentrations of COD,TP,NH+4-N,TN in the effluent were 16.39,0.38,1.44,16.38 mg/L,respectively,and the quality indexes of effluent could reach the water quality standard for urban miscellaneous water consumption. |
