微电解法预处理对氟硝基苯废水的研究

Study on the Pretreatment of p-Fluoronitrobenzene Wastewater by Microelectrolysis

采用废铁屑微电解法对对氟硝基苯废水进行预处理 ,在铁粉投加量为 3 .0g/L、pH为3.0、反应时间为 3h、催化剂氯化铵用量为 2 .0g/L的条件下 ,对氟硝基苯转化为氨基氟苯的转化率为 70 % ,出水的BOD5/COD值由 0上升到 0 .2

In the Pretreatment of p fluoronitrobenzene wastewater by microelectrolysis process with iron scrap, the conversion rate of p fluoronitrobenzene to p fluoroaminobenzene is 70% and BOD 5/COD value of effluent is increased from zero to 0.27 under the conditions of iron scrap dosage of 3.0 g/L, pH3.0, reaction time of 3 h, catalytic ammonium chloride dosage of 2.0 g/L.
