Abstract

Abstract: This paper deals with the treatment of fumaric acid-containing wastewater by using the aerobic biofilm contact oxidationthat isto degrade the fumaric acid in wastewater by using peltate fibre filling as the biological supportthus expounding the mechanism and technology of treating wastewater．Experimental results indicate that the degradation of fu-maric acid wastewater accords with the first order reaction principle；that the optimal ratio of the gas to water is16and the hydrodynamic retention time is8h；that when the inlet COD and BOD 5 are respectively up to1800mg／L and520mg／Lunder stable conditionsthe outlet COD and BOD 5 of the reactor are respectively216mg／L and114mg／Lwhile the B／C value is0．53；and that when the cubage load increases by6．6timesthe COD removal of the reactor will approach to70％ after working for40hwhich reveal.

Key words: fumaric acid, wastewater, biofilm, bio-contact oxidation
