摘 要:采用以CuO-ZnO多孔陶瓷為粒子電極,以鉛板為陽(yáng)極,不銹鋼為陰極的三維電催化氧化法處理檳榔廢水?疾炝穗娊赓|(zhì)投加量、初始pH值、工作電壓、曝氣量對檳榔廢水COD去除率的影響,并運用紫外吸收光譜對檳榔廢水降解過(guò)程進(jìn)行分析。結果表明,三維電催化氧化法處理檳榔廢水優(yōu)化條件為:氯化鈉投加量為10 g/L,初始pH值為7左右,工作電壓為20 V,曝氣量為40 L/h,反應2 h后,檳榔廢水COD去除率可達65.22%。紫外吸收光譜分析結果表明,三維電催化法對檳榔廢水中的 COD 具有很好的降解效果,檳榔廢水的毒性降低,可生化性提高。

Abstract:The betel wastewater has been treated by a three-dimensional electro-catalytic oxidation with CuO-ZnO porous ceramics as the particle electrode, stainless steel as the anode and lead plate as the cathode. The electrolyte dosage, initial pH value, voltage, aeration rate were investigated on the removal of COD. The UV absorption spectra were used for monitoring the degradation process of the betel wastewater. The best removal of COD (65.22%) was occurred under the following conditions: NaCl dosage of 10 g/L, initial pH around 7.0, the working voltage of 20 V, aeration rate of 40 L/h, the electrolysis time of 120 min.
Key words:betel wastewater; three-dimensional electro-catalytic; pre-treatment
