【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。更多还原

【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.更多还原
