α-MnO2活化过硫酸盐对头孢曲松钠废水的处理研究

Study on the Treatment of Ceftriaxone Sodium Wastewater by Synthetic Manganese Dioxide Activated Persulfate

本研究针对头孢类抗生素类废水,通过过硫酸盐高级氧化技术进行降解。实验结果表明头孢曲松钠废水在反应温度为60℃,pH为6,过硫酸盐浓度为250 mmol/L的条件下,效果最好,头孢曲松钠废水去除率可达95.1%。并通过水热法制备二氧化锰活化过硫酸盐,相比于不投加二氧化锰,去除率由70.2%上升到89.7%。表明二氧化锰可明显提高头孢曲松钠废水去除率。

The degradation of cephalosporin antibiotic wastewater by persulfate advanced oxidation technology was studied.The result of this experiment showed that the degradation effect of ceftriaxone sodium wastewater was the best when the reaction temperature was 60℃,the optimum pH was 6,and the concentration of persulfate was 250 mmol/L.The removal rate of ceftriaxone sodium wastewater reached 95.1%.Synthetic manganese dioxide activated persulfate was prepared by hydrothermal method,and the removal rate of ceftriaxone sodium wastewater by the manganese dioxide activated persulfate increased from 70.2%to 89.7%,compared to persulfate without manganese dioxide.The results showed that synthetic manganese dioxide could obviously improve the removal rate of ceftriaxone sodium wastewater.
