摘要：In this paper, the biological aerated filte r (BAF) was employed to treat the wastewater containing polyether polyols (PP). Factors that affected polyether polyols and CODCr removal were evaluated experimentally, such as pH, hydraulic loading, hydraulic retention time (HRT) and polyether polyols volume loading, etc. The results showed that at pH 7.0〜8.0, hydraulic loading rate 0 .0 6 U 8 m3/(m2 h), HRT more than 3.5h and PP loading 0 .0 4 U 5 g /(m 3 d), the removal rate of PP and CODCr was more than 93% and 87%, respectively. The mathematical model of m atrix (PP) was obtained by the Monod5s relation and the experimental parameters of the model were 1.97 g/(m2 d) and 9.78mg/L.
