摘要

Abstract

The aerated zero-valent iron was used to treat the high salinity pesticide wastewater containing cyanide

which reduced post-processing load and the toxicity of wastewater and created favorable conditions for subsequent treatment.The results indicated

under the conditions that pH was 4

Fe∶C(g/g）was 1∶1

aeration flux was 150 L·h-1

reaction time was 3h

the removal rate of COD was 61.6% and the concentration of effluent’s CN- was 3.52 mg·L-1.Through the primary dynamics analysis

COD removal process was divided into three phases.First

the acidic dissolution phase of iron

the COD removal by aeration phase

the dissolution velocity of iron was 3.03 g TFe·h-1.Second

the high velocity phase

about 87.1% of COD that being removed in all process was transformed.Third

the stagnation phase of zero-valent iron

the COD removal was stopped.
