TMBA medicine intermediate effluent with high chroma and COD is difficult to be treated by microbe. The adding-alkali aeration method is effective. The biodegradability of effluent is improved obviously and the value of BOD5/COD increases from 0.24 to 0.35. The anaerobic-aerobic combined technique is introduced to treat TMBA effluent .the results showed that the COD of the final effluent water was ≤ 100 mg·L^-1, and the chroma dropped to colorless.The comprehensive last effluent of biochemical treatment reaches national sewage comprehensive emission standard ( GB8978-1996) primary standard.
