Waste treatment

摘要

A method and apparatus for the treatment of an aqueous organic waste liquid to provide a treated liquid containing less organic matter the apparatus comprises a treatment reservoir defining first and second treatment zones separated by a porous membrane 10. Carbon-based adsorbent material 2 capable of electrochemical regeneration is provided in said first and second treatment zones. First and second electric current feeders 8 are operably connected to the adsorbent in the first and second treatment zones respectively. A controller 9 operates the electric current feeders to pass an electric current through the adsorbent in the treatment zones in one direction to regenerate the adsorbent in one of the treatment zones and to then reverse the direction of the current applied to the adsorbent to regenerate the adsorbent in the other treatment zone. Advantageously the apparatus facilitates aqueous waste water treatment such as radio-active waste in a batch or continuous manner.
