摘　　要：电镀生产过程产生的大量有毒物质存在于工业废水中,如果电镀废水未经处理而直接排放,会污染饮用水和工业用水,对生态环境产生危害。为了降低电镀废水对环境的影响,本研究提出一种基于协同硫自养反硝化的工业酸洗电镀废水处理技术。结果显示,当高度为40 cm,进水氮浓度为200 mg/L时,NO_(3)^(-)-N的浓度最大值为52 mg/L。当进水氮浓度为80 mg/L时,NO_(3)^(-)-N的浓度最小值为11 mg/L。当高度为40 cm,进水氮浓度为200 mg/L时,SO_(4)^(2-)的浓度最大值为1 198 mg/L。当进水氮浓度为80 mg/L时,SO_(4)^(2-)的浓度最小值为689 mg/L。研究提出的方法能有效地降低出水氮浓度,提高废水中硝酸盐的去除率。The large amount of toxic substances generated during the electroplating production process exist in industrial wastewater,if the electroplating wastewater is discharged directly without treatment,it will pollute drinking water and industrial water,posing a threat to the ecological environment.In order to reduce the environmental impact of electroplating wastewater,this study proposes an industrial acid washing electroplating wastewater treatment technology based on synergistic sulfur autotrophic denitrification.The results show that when the height is 40 cm and the influent nitrogen concentration is 200 mg/L,the maximum concentration of NO_3~--N is 52 mg/L.When the influent nitrogen concentration is 80 mg/L,the minimum concentration of NO_3~--N is 11 mg/L.When the height is 40 cm and the influent nitrogen concentration is 200 mg/L,the maximum concentration of SO_4~(2-)is 1 198 mg/L.When the influent nitrogen concentration is 80 mg/L,the minimum concentration of SO_4~(2-)is 689 mg/L.The proposed method can effectively reduce the nitrogen concentration in effluent and improve the removal rate of nitrate in wastewater.
