兰炭废水.doc

第1页摘要本论文通过自行设计制作的二维电极反应器,对焦化厂的兰炭废水进行电化学氧化降解,主要是去除废水中的COD和氨氮。本实验主要是利用电化学氧化中的电芬顿法,详细分析电解电流、电解时间、废水原始pH值、极板间距及双氧水投加量等因素在二维电极体系中对污染物质降解效果的影响。研究二维电极电催化降解兰炭废水的影响因素。由实验数据表明:适宜的处理条件是:电解电流为5A,电解时间210min,,电解质(Na2SO4)浓度为10g/L,双氧水投加量1mL/100mL废水,不加酸碱调节pH值,常温反应。COD的去除率最大接近80%,氨氮的去除率大于80%。关键词:二维电极;电Fenton法;COD;氨氮第2页ABSTRACTInthispaperthedesignandmanufacturebytwo-dimensionalelectrodetothereactor,theorchidcarbonwastewaterplantforelectrochemicaloxidationdegradation,mainlyistheChemicaloxygendemand(COD)removalandammonianitrogen(NH3-N),urrent,electrolytictime,wastewaterprimitivepHvalue,platespacingandhydrogenperoxidedosingquantityfactorsintwo--:urrentas5A,electrolytictime210min,,electrolyte(Na2SO4)concentrationof10g/L,doubleoxygendosingquantity1mL/100mLcanisterwastewater,donotaddacid-baseadjustpHvalue,thenormalreactionChemicaloxygendemand(COD)removalefficiencyofmaximumcloseto80%,Ammonium-Nitrogen(NH3-N)removalratemorethan80%.Keywords:Two-dimensionalelectrodeelectricity;Fenton;Chemicaloxygendemand(COD);Ammonium-Nitrogen(NH3-N)第1页目录第一章绪论................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
