摘要
采用铁碳微电解预处理腈纶废水,通过正交试验和单因素试验研究了铁碳投加量、铁碳比、水力停留时间(HRT)及pH对处理效果的影响。试验结果表明:铁碳比为3∶4、铁碳投加量为200 mg/L、HRT为2 h、pH为4时,预处理效果最好,此时COD去除率达到33.53%,废水可生化性由0.18提升到0.34。
Acrylic fiber wastewater has been pretreated by iron carbon micro-electrolysis,and the influences of iron-carbon dosage,iron/carbon mass ratio,reaction time,and pH value on treatment effects have been investigated,thr-ough single factor tests and orthogonal tests.The results show that the pretreatment effect is optimal,when the iron/carbon mass ratio is 3∶4,iron-carbon dosage is 200 mg/L,HRT=2 h,and pH=4.Under these conditions,the COD removing rate by iron-carbon micro-electrolysis process reaches 33.53%,and the biodegradability is increased from 0.18 to 0.34.
