摘　　要：采用铁炭微电解/Fenton试剂法联合工艺预处理对叔丁酚甲醛树脂合成废水,考察了pH、反应时间及H2O2投量等因素的影响。结果表明,当原水COD为12300～17600mg/L时,在控制原水pH值为2.0、反应时间为120min的条件下,铁炭微电解对COD的去除率>50%;向铁炭微电解出水中再投加2.4mL/L的H2O2(30%)进行Fenton反应,在常温(20～30℃)下反应60min对COD的总去除率>83%,废水的B/C值从最初的0.034提高到0.35左右。对预处理出水(调节pH并稀释)进行后续的生化处理,出水水质能够稳定达到《污水综合排放标准》(GB8978—1996)的二级排放标准要求。The combined process of ferric-carbon micro-electrolysis and Fenton reagent was used to pretreat the wastewater from p-tert-butylphenol formaldehyde resin synthetic process. The influence factors of pH,reaction time and H2O2 dosage were investigated. The results show that when the influent COD is 12 300 mg/L to 17 600 mg/L,pH is 2.0 and the reaction time is 120 min,the removal rate of COD by ferric-carbon micro-electrolysis is above 50%. For treatment with the Fenton reagent,when the H2O2 (30%) dosage is 2....
