[Abstract]:The water quality of penicillin wastewater is characterized by high concentration of CODcr, high concentration of sulfate, large fluctuation of water quantity and difficulty of degradation. The problem of water treatment is not up to standard for a long time. In this paper, the advanced treatment of effluent from penicillin production wastewater after biochemical treatment was studied by Fenton reagent oxidation method and catalytic reduction of Cu / Fe, aerated iron-carbon microelectrolysis and ozone oxidation. In order to provide a reference for the advanced treatment of penicillin production wastewater. The Fenton reagent oxidation method Cu- / Fe catalytic reduction method, aerated iron-carbon micro-electrolysis method and ozone oxidation method were used. The influence factors of the four methods on the treatment effect were investigated. The results show that the optimum conditions of Fenton reagent oxidation method are that the dosage of H2022 (30wt%) is 100ml / L, Feb2) and the molar ratio of H202 (molar ratio) is 1 / 10 (pH = 3.0), the reaction time is 0.5 h, and the removal rate of CODcr reaches 89.7BOD5 and the removal rate of NH _ 3-N reaches 98.8wt%. The optimum conditions are as follows: (1) the ratio of H _ (20) to H _ (20) is 100 ml / L, and the molar ratio of H _ (202) to H _ (202) is 3.0% and 0.5 h respectively. The optimum conditions for Cu- / Fe catalytic reduction are as follows: the reaction temperature is 25 鈩，
