摘要
采用电凝聚方法,作为垃圾渗滤液前处理工艺,且研究中采用槽底曝气装置,既起到了搅拌作用,同时也起到了气浮作用。以铝板为极板材料,当处理进水COD浓度为9399.3mg/L,电流密度为1.2A/dm2,极板间距为10mm,处理时间为40min时,COD的去除率达到43.3%,NH3-N的处理效率最高可达到80.1%。
Landfill leachate is hard to treat up to national discharge criteria only by biological treatment process. Electro-coagulation as pre-treatment was described, and aeration device was equipped at the bottom to mix and float wastewater. Aluminum as material of polar plate, when concentration of inlet COD was 9399.3mg/L, electrical current density was 1.2A/dm2, distance of each two polar plate was 10mm and reaction time was 40min, the removal efficiency of COD and NH3-N was about 43.3% and 80.1% respectively.
