ANAEROBIC DIGESTION APPARATUS FOR TREATING HIGH ORGANIC WASTE WATER AND METHOD FOR ANAEROBIC DIGESTION TREATING HIGH ORGANIC WASTE WATER

摘要

The present invention relates to a high concentration organic wastewater treatment apparatus and a method for treating organic wastewater. Specifically, according to an embodiment of the present invention, a high concentration organic wastewater treatment apparatus includes a dehydrator for dehydrating high concentration organic wastewater into a sludge cake and effluent; A sedimentation tank for flocculating and precipitating organic matters in the effluent discharged from the dehydrator; A first electrochemical treatment device for oxidizing the organic matter contained in the effluent discharged from the settling tank through a reaction between iron ions and hydrogen peroxide; And a second electrochemical treatment apparatus for generating nitrogen gas electrochemically from the effluent treated in the first electrochemical treatment apparatus.
