Abstract: Electrochemical degradation of effluent from pulp alkaline treatment was studied with SiC anode and stainless steel gauze cathode.The result showed:pH value of the effluent increased at first,then decreased;electroconductivity decreased at first,then increased;COD and chroma of effluent decreased significantly in the early stage.UV spectra also showed the effectiveness of electrochemical degradation on the effluent.

Key words: SiC electrode, electrochemistry, pulp alkaline treatment effluent
