The research of application of powder active carbon in removing antibiotic pollution

This article discusses the effect of active carbon in the aspect of absorbing antibiotic pollutions. Under the experimental conditions, 30 kinds of antibiotics are used. And active carbon´s removal rate is about 96.54% to 100%. Nadilixic acid, Oxytetracycline and Lincomycin are selected as representatives. Based on the data, when the pollution is up to 1mg/L and the removal rate is >;99.99%, the dose of usage of active carbon should be 115mg/L (Nadilixic acid), 75mg/L (Oxytetracycline) and 25mg/L (Lincomycin). According to other antibiotics´ difficulty of being absorbed by active carbon, this paper calculates the use of active carbon in the similar situation. To long-term pollution which is less than 1ug/L, The use of active carbon should maintain in the range of 1 to 35mg/L, so that antibiotics pollution can be removed effectively.
