Abstract
The pretreatment of internal electrolysis to a certain pharmaceution wastewater was investigated ,and the effect of internal electrolysis was enhanced by aeration and adding oxidant.The result showed that removal rates of CODCr could reach more than 70%, removalrate of color was 90% if the weight proportion of iron and charcoal was 1:1, pH 3.0, react time 3 hours and the dosage of oxidant 500mg/L, and then the wastewater could become degradable for biochemical treatment.
