摘要
本实验对BSBR和SBR法处理生活污水的效果及BSBR的运行方式进行了研究。实验表明,处理生活污水时,BSBR处理污水时COD去除率达到95%,氨氮去除率达到97%,处理效果优于常规SBR。采用BSBR处理易生物处理污水时,采用限制曝气的进水方式,且曝气时间不超过2小时时能取得最好的处理效果。
In an information society,the English knowledge in capacity for college students has gradually been improved and its range is also enlarged.If teachers overlook summing up the knowledge which the students have gained and improving their skills in English,it will be hard for students to learn English well.In educational circles people often say'teaching method isn’t fixed ',but it is of the same view to give students some basic regularity,let students have enough abilities and make knowledge which the students have gained assimilate and systematize etc.Facing medical college students’tasks are arduous and the students often seem at a loss.In English lessons,it is necessary for teachers to help students find out some basic laws,give students enough skills and methods,let students sum up and classify knowledge which is scattered,disorderly,bit by bit and even fragmented.
