复合菌群处理城市污染水体的试验研究

Treatment of urban polluted waters by complex bacterium

应用复合菌群的富集培养液进行了城市污染水体的处理试验,实验表明:对水体污染物CODMn、NH3 N的去除,微生物最佳投加量为0 1/1000,对PO3-4 P的去除,微生物最佳投加量为0.7/1000;水体污染物CODMn的质量浓度在14.2mg/L以上时,修复作用明显;水体溶解氧条件影响微生物对水体的修复效果,较高的溶解氧有利生物修复作用。

Enriched culture medium of complex bacterium is used to treat urban wastewater in the experiment. It shows that the removal effects of COD_(Mn), NH_3-N are the best when bacterium of 0.1/1000 is added, while PO^(3-)_4-P is most removed when bacterium added is 0.7/1000. The rehabilitation of polluted water is most obvious when the concentration of COD_(Mn) is higher than 14.2mg/L.The bioremediation effect of complex bacterium is influenced by DO in the water, and higher DO is beneficial to bioremediation.
