To enhance the biochemical degradability of the wastewaters from the medicine manufacturer, especially those of high containing COD discharged from the production of anti-bacterium and anti-virus medicine, improving their biochemical degradability is one of the factors to better the treatment of wastewaters of this kind. In this paper we present the iron electrical chemical method adopted for pretreatment of the wastewater mentioned above. The results showed; the wastewater from medicine production can be properly treated, with its biochemical degradability (BOD5/COD) improved by 50%.
