| Abstract: | It is introduced that the process design and running effect of treating wastewater from producing polyether polyols by air floatation-hydrolysis acidification-UBF-biological contact oxidation-oxidation ditch process.This process has advantages of low energy consumption and easy control.Under normal condition when COD of influent is 8 000 ～ 12 000 mg /L and BOD5 is 1 200 ～ 1 500 mg /L,the mean residual COD in effluent will be lower than 250 ～ 300 mg /L and BOD5 will be lower than 50 ～ 80 mg /L,which can meet the third-order of "National Standard for Comprehensive Discharge of Wastewater(GB8978-1996)". |
