纸浆碱处理段废水的电化学降解研究

STUDY ON ELECTROCHEMICAL DEGRADATION OF PULP ALKALINE TREATMENT EFFLUENT

用硅碳棒作为阳极 ,不锈钢网为阴极对纸浆氯漂碱处理段废水进行电氧化反应。结果表明 :电解过程中 pH值先升高后降低 ,电导率先降低后升高 ,废水色度和COD值在开始处理阶段会下降很大 ,pH值对色度降低的影响不大。同时通过紫外光谱图也表明硅碳棒降解废水是有一定的效果。

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.
