摘要:

通过实验研究了活性污泥在缺氧及好氧条件下对萘普生、苯扎贝特、布洛芬及罗红霉素的去除行为。结果表明,在采用活性污泥去除萘普生及苯扎贝特的过程中吸附与生物降解共同作用,以生物降解作用为主。活性污泥对4种药品的吸附作用大小依次为罗红霉素 >苯扎贝特 >萘普生 >布洛芬。在缺氧及好氧条件下,活性污泥均能有效地生物降解苯扎贝特和萘普生。罗红霉素对活性污泥的致急性毒性浓度值高于布洛芬。

Abstract:

The removing actions of naproxen,benzafibrate,ibuprofen and roxithromycin by activated sludge under aerobic and anoxic conditions have been studied through experiments. The results show that in the process of using activated sludge for removing naproxen and benzafibrate,adsorption and biodegradation work co-efficiently,whereas mainly biodegradation. The order of adsorption degree for the four kinds of medicine are roxithromycin >bezafibrate >naproxen >ibuprofen. Under aerobic and anoxic conditions,activated sludge can effectively biodegrade benzafibrate and naproxen. Roxithromycin has higher acute toxicity concentration value for activated sludge than ibuprofen.

Key words: medicine, adsorption, biodegradation, activated sludge
