摘要/Abstract

摘要： 针对印染废水水质特性，在PbO₂/Ti阳极、不锈钢板阴极的电解反应器中研究了电化学氧化对印染废水生化出水的处理效果. 试验结果表明，电氧化工艺可以实现化学需氧量（Chemical Oxygen Demand，COD）、氨氮和色度的同步去除. 在电流密度10 mA·cm^-2时电解60 min，废水中COD、氨氮、色度、氯离子浓度以及pH值等指标均可达到GB/T 19923-2005《城市污水再生利用工业用水水质》中工艺与产品用水标准，电流效率达45.6%，吨水能耗4.1 kW·h.

关键词: 印染废水, 回用, PbO2/Ti电极

Abstract: In response to the characteristics of dye wastewater, the electrochemical oxidation of effluents from the biochemical process of dyeing wastewater was studied in the electrochemical reactor using PbO₂/Ti electrode as the anode and stainless steel plate as the cathode. The results revealed that the electrochemical oxidation could simultaneously remove the Chemical Oxygen Demand (COD), ammonia and chromaticity. At the residence time of 60 min and current density of 10 mA·cm^-2, the COD, ammonia, chromaticity, concentration of chloride ion and pH values could meet the water standards for “the reuse of urban recycling water-water quality standard for industrial use” (GB/T 19923-2005) with the current efficiency of 45.6%. The energy consumption was 4.1 kW·h for advanced treatment of per ton wastewater.

Key words: Dyeing wastewater, reuse, PbO₂/Ti electrode
