Abstract
The rice husk activated carbon (RHAC) was examined to treat the sewage exhausted from a pig house. The RHAC reduced the sewage stain greater than commercial granular coconut-shell activated carbon and activated carbon fiber did. The RHAC was useful to reduce the total organic carbon content and the suspended substance concentration of the sewage, while hardly reduced biological oxygen demand. Mesopores at the diameter of 10-50nm, which were preferentially produced on the RHAC, were suggested to be effective to remove a brown stain in the sewage.
