Abstract:Tea polyphenols was a kind of natural antioxidant. Its production wastewater was hardly treated. After the pretreatment with the modified aluminium chloride and the celatom, the tea polyphenols wastewater was treated by the integrated anaerobic-aerobic reactor of immobilized microbe. At 26~30 ℃, when the inlet CODCr, OLR, tea polyphenols and chroma were 6.4~20.2 kg COD/(m3·d), 5200~18000 mg/L, 160~1360 mg/L and 1000, The removal rates of the CODCr, Tea Polyphenols and chroma removal rates were 90%~99%, 75%~98% and 90%~94%, respectively. From the SEM pictures of bio particles, It was found that the particles of A and O parts were very close to sphere, a large quantities of microbial colonies accreted at the face and in the holes of the particles and the microbe in the holes well grew than at the face. The anaerobic microbial colonies mostly were similar to Methanithrix sp., Methanosarcina, and the aerobic were bacilli. On the base of the Monod’s equation, the reaction kinetics models of tea polyphenols were gotten. These results proved that the integrated anaerobic aerobic reactor of immobilized microbe can be adapted to treat the high concentration tea polyphenols wastewater.
