摘　　要：通过化学合成法制备出磁性大孔树脂类Fenton催化剂,研究其催化降解盐酸黄连素制药废水的效能,同时考察了pH值、H_2O_2投加量、催化剂投加量及废水初始浓度对其降解效能和反应速率的影响。结果表明:在盐酸黄连素的初始质量浓度为800 mg/L、催化剂投加量为15 g/L、H_2O_2投加量为297 mmol/L、pH值为4、室温(25.0±0.5)℃的条件下,盐酸黄连素的降解率为84.4%,达到最高。研究表明,该非均相类Fenton反应体系对pH值的使用范围广,且催化剂易于分离,反应数次后依然具有较高的催化活性,重复利用率高。Magnetic macroporous resin was prepared by chemical synthesis, and the catalytic degradation performance of it on wastewater from berberine hydrochloride production was studied. The effects of pH value, dosage of H202 and catalyst on the degradation efficiency and the reaction rate were investigated. The results showed that, at indoor temperature（25.0 ± 0.5） ℃, under the condition that the initial mass concentration of berberine hydrochloride was 800 mg/L, the dosage of catalyst and H2O2 were 15 g/L and 297 mmol/L respectively, the pH value was 4, the deagradation rate of berberine hydrochloride reached the highest, which was 84.4%. The study indicated that, the said non-homogeneous Fenton-like reaction system could tolerate wide pH range, besides, the catalyst could be separated easily, and maintained high catalytic activity even after several times of reaction, which presented good repeating utilization factor.
