LAS, COD and NH -N w ere evaluated. The resu lts suggested that at normal temperature, pH = 615~ 7, the reactor cou ld operate under the optmi ized operating cond itions at a flow of 0 mL /m in, and the removal rate ofLAS, COD and NH -N w as about 97% , 80% and 60% respectively. The ef- fluentmet theM iscellaneous Dom esticW astew ater Quality Standard ( CJ/T48-99). In addition, the biocompat-i b ility and regenerability performance of PAN-ACF w as good in the expermi ent.
