| 摘 要： | 研究了不同条件下EM菌液对富营养化水体的净化效果,结果表明:以COD为主要处理目标的水体中,EM菌液的最适条件为V(EM)∶V(污水)=1/1 000、连续曝气、T＞25℃；以脱氮为主要处理目标的水体中,其最适条件为V(EM)∶V(污水)=8/1 000、间歇曝气、T＞25℃、pH为中性偏碱；以除磷为主要处理目标的水体中,EM菌液最适条件为V(EM)∶V(污水)=8/1 000、间歇曝气、T＞25℃、pH为中性偏碱.考虑到整体性、经济性和实用性,EM菌处理富营养化水体的最佳条件为V(EM)∶V(污水)=1/1 000、间歇曝气、T＞25℃、pH为中性偏碱. |

| Abstract: | The purification effects of effective microorganism(EM) to eutrophic water under different conditions were studied.The results showed that the best conditions for EM treating COD in waste water were as follows: V(EM):V(sewage water)=1/1000,continuous aeration,and T>25℃;the best conditions for EM treating N in water were: V(EM):V(sewage water)=8/1000,intermittent aeration,T>25℃ and pH at neutral-to-slightly-alkaline;the best conditions for EM treating P in water were: V(EM):V(sewage water)=8/1000,intermittent aeration,T>25℃,and pH at neutral-to-slightly-alkaline.For integrity,economy and practicality consideration,the best conditions for EM treating eutrophic water were: V(EM):V(sewage water)=1/1000,intermittent aeration,T>25℃,and pH at neutral-to-slightly-alkaline. |
