| Abstract: | By orthogonal experiment design method, this paper discussed the influencing factors on the treatment of heparin sodium wastewater with Fenton＇s reagent, which resulted in the sequence of influencing factors and the best technological conditions. The results showed that the sequence of influencing factors was pH value, amount of Fe^2＋ , dosage of H2O2 and reaction time, and with pH value of 6.00, FeSO4 - 7H20 dosage of 2.5 g/L,H2 O2 concentration of 2.75‰（V/V） and churning time of 25 rain, CODcr reduced from 1 268.44 mg/Lafter pre-treating to less than 70mg/L, the removal efficiency of which reached 94.5 %. |
