摘　　要：通过改性泥炭和改性沸石对微污染水体中污染物的去除实验的研究,得出改性泥炭和改性沸石单独处理微污染水时都能有效地去除水体中COD、氨氮、总磷,联合作用时对水体中的COD、总磷可以达到更高的去除率,但对氨氮的去除率有所下降。结果表明:微污染水在最适实验条件下进行吸附实验得出的效果是水体中的化学需氧量(TCOD)、氨氮(NH+4-N)、总磷(TP)的浓度分别从77 mg/L、3.75 mg/L、0.40 mg/L降低到20.06 mg/L、0.041 mg/L、0.35 mg/L。两种吸附剂联合作用对污染物的去除率比吸附剂单独作用污染物要高。Through the study on removal effect of pollutants in micro - polluted water with modified peat and modified zeolite, this paper concluded that modified peat and modified zeolite can effectively remove COD, ammonia, total phosphorus in water. The combined effects can achieve a high removal rate for COD and total phosphorus in water bodies, but the removal efficiency of ammonia nitrogen in water bodies will decline. The results show that the concentration of water chemical oxygen demand （TCOD） , ammonia （NH4^＋ -N）, total phosphorus（TP） in micro -polluted water decreased from 77 mg/L,3.75 mg/L, 0. 40 mg/L to 20. 06 mg/L, 0. 041 mg/L, 0. 35 mg/L, respectively. The joint action of adsorbents can achieve better removal rate than an individual adsorbent..
