摘要
水生绿肥净化城市污水试验结果表明,水生绿肥对污水具有明显的净化效果,放养水葫芦的污水中 BOD_5、COD_(Cr)、Cr_总、TN分别比对照降低12.03、83.00、0.003、5.348 mg/L;放养水蕹菜的污水中上述各指标分别比对照降低20.95、97.00、0.003、3.696mg/L。
The effect of aquatic green-manure on purification of city sewage was studied. The result showed that aquatic green-manure had obvious effect on the purification of the sewage. BOD5, CODCr, total Cr and TN in the sewage planted with water hyacinth were 12.03,83.00, 0.003and 5. 348mg/L lower respectively than that of check. The above figue in the sewage planted with water sinach were decreased by 20.95,97.00,0.003and3.696mg/L respectively.
