摘要
通过中试将活性污泥生物增效技术引入到对精对苯二甲酸(PTA)废水的处理中,并与原PTA废水处理系统进行对比。结果表明,与原处理系统相比,投加生物增效菌种后,中试装置对COD的去除率、抗冲击能力和污泥沉降性能都有明显提高,污泥中的微生物数量和种类也有明显增多,系统对PTA废水的处理能力得以提升。
The bioaugmentation technology was applied to treat the pure terephthalic acid (PTA) wastewater in pilot test of activated sludge process, and the treatment efficiency was compared with that by the original treatment system. The results show that compared with the original treatment system, COD removal rate, shock resistance and sludge settleability of the pilot test setup are significantly improved by adding bioaugmentation fungus. The quantity and species of microorganisms are increased significantly,and the treatment ability of PTA wastewater is promoted.
