摘要
采用微电解—混凝沉淀工艺对间二硝基苯生产废水进行预处理。确定了最佳工艺参数;pH为3,停留时间为60min,铁碳比为2∶3。经处理后间二硝基苯生产废水的生化性大大提高,废水中硝基苯的去除率可达到70％以上。
This paper deals with the pretreatment of dinitroben zene-manufacturing wastewater with purpose to improve its biodegradation. A bench-scale experiment was conducted using a plexiglass column filled with scrap iron and a Warburg respirometer to determine the upgrade of biodegradable characteristics of the wastewater after micro-electrolysis.
