摘　　要：采用铁炭微电解-混凝法预处理糠醛废水,研究了材料粒径、停留时间、进水pH值等相关因素对处理效果的影响。结果表明,在铁屑粒径1~2mm,活性炭粒径<1mm,进水pH值2.10~2.40,反应40min的条件下,经混凝处理后CODCr去除率可达80%以上,废水BOD5/CODC r值从0.38上升到0.70,有利于后续生化处理。An iron-carbon micro-electrolysis and coagulation process was used to treat furfural wastewater.The effect of the granularity of iron filings and active carbon,hydraulic retention time,wastewater pH on treatment was studied.The results showed that COD_(Cr) removal rate reached to 80% and BOD_(5)/COD_(Cr) increased from 0.38 to 0.70 under the conditions of the granularities of iron filings and active carbons,wastewater pH and hydraulic retention time were 1～2 mm,<1 mm,2.10～2.40,and 40 min,respectively aft...
