摘要
含磺胺嘧啶(SD)和酮基布洛芬(KP)的合成制药废水对微生物有较强的抑制作用,故不能使用生物法对其进行处理。本文研究表明,通过硫酸酸析可以明显改善废水的可生化性,并且有利于厌氧菌和好氧菌的驯化、筛选和复配,经过酸析后的废水适宜进行厌氧和好氧处理。经酸析-厌氧-好氧联合处理工艺后,废水的化学需氧量(COD)值由2 525 mg.L-1降到150 mg.L-1以下,最终出水COD值为145 mg.L-1,COD总去除率达到94%。试验分析证明最佳的酸析条件是pH=2,酸析时间为40 min。酸析预处理是后续微生物处理高浓度难降解含磺胺嘧啶(SD)和酮基布洛芬(KP)的合成制药废水的关键。
Containing sulfadiazine （SD） and ketoprofen （KP） on the synthesis of pharmaceutical wastewater has a stronger effect on treatment of microbes. It is not used to be dealt with by biologic wastewater treatment. This study shows that acid separation can improve bio-chemistry catabolism of the synthesis of pharmaceutical wastewater clearly. The acid separation to increase the biodegradability of waste water is conducive to aerobic and anaerobic bacteria domesticated, screened and compound treatment. Aerobic and anaerobic wastewater treatment can be done well after acid separated. Analysis of experimentation has proved that COD （ chemical oxygen demand） of original wastewater falls below 150 mg .L^-1 from 2 52 5 mg.L^-1, at last reaches to 145 mg.L^ -1 finally. The total removal rate of COD is about 94%. According to test it can be gotten that acid separation of the best conditions is ： pH = 2, acid separating process time is 40 minut. Tests show that pretreatment of acid separation to high concentration of chemical synthesis is the key to pharmaceutical wastewater which is done by aerobic and anaerobic bacteria after acid separation.
