抗生素生产废水二级生物处理出水通常含部分难降解有机物,若不经处理直接排放,将对环境产生毒害,威胁人类身体健康。紫外光分解过硫酸盐产生SO-4·是一种新型的高级氧化技术。以亚胺培南生产废水二级出水为研究对象,对比了K_2S_2O_8氧化、UV辐射以及UV和K_2S_2O_8联合使用对其处理效果,系统研究了K_2S_2O_8投量、反应pH等因素对UV-K_2S_2O_8深度处理亚胺培南生产废水效果的影响。结果表明UV-K_2S_2O_8耦合是一种有效的去除废水中难降解有机污染物的技术,消除抗生素废水处理过程中存在的脱色不彻底等问题,在最优条件下,对COD去除率可达100%,TOC去除率达94.4%。为抗生素生产废水的深度处理提供技术参考。
Antibiotic production wastewater secondary biological treatment of effluent usually contains part of the refractory organic matter, if untreated direct emissions, will have a toxic environment, threatening human health. UV-light decomposition of persulfate to produce SO-4 · is a new type of advanced oxidation technology. Taking imipenem wastewater secondary effluent as research object, the effect of K 2 S 2 O 8 oxidation, UV radiation and combination of UV and K 2 S 2 O 8 was compared. The effects of K 2 S 2 O 8 input and reaction pH on UV-K 2 S 2 O 8 deep treatment were systematically studied Effect of amine penem wastewater treatment. The results show that the UV-K 2 S 2 O 8 coupling is an effective technology to remove refractory organic pollutants in wastewater and eliminate the problem of incomplete decoloration during the treatment of antibiotic wastewater. Under optimal conditions, the COD removal rate can reach 100% , TOC removal rate of 94.4%. Provide technical reference for the advanced treatment of antibiotic wastewater.
