摘要:

磺胺间甲氧嘧啶类药物在生产过程中产生大量高浓度和高COD废水。本工作以前期合成的非苯乙烯骨架吸附树脂为基本吸附材料,开展了CaO絮凝沉淀-树脂吸附两步法处理此类废水的研究。结果表明:废水的COD可从原来的11 000 mg/L降至321 mg/L,絮凝沉淀、树脂吸附的COD去除率分别达84.33%81.66%(总去除率97%)。此废水处理工艺简单、运行费用低,树脂经5次吸附-脱附后仍保持良好吸附性能,具有很好的实际应用前景。

Abstract:

A large amount of high chemical oxygen demandCODwastewater was generated in the synthesis of sulf amonomethoxine drugs. Based on a novel non-styrene adsorptive resin synthesized by the authorsthe research on the treatment of pharmaceutical wastewater was performed by the process of CaO flocculation sedimentation and resin adsorption. The results showed that COD of the original wastewater could be decreased to 321 mg/L from 11000 mg/L by the novel process. 84.33% and 81.66% COD removal percentages could be achieved by CaO flocculation sedimentation and resin adsorptionand the total COD removal efficiency was over 97%. After 5 times of adsorption-desorption cyclesthe resins still kept high adsorptive capabilities. This simple and economical technique for pharmaceutical wastewater treatment shows good prospects for practical application
