铁碳内电解技术处理酸性红B的动力学研究

he hard carbon in electrolysis process was used to treat the acid red B dye wastewater as an pre-treatment method. The treating efficiency of the acid red B dye wastewater by hard carbon in electrolysis process were researched. The degradation rate of acid red B dye wastewater is fit with first-order dynamics under different reaction conditions, it can be known: when Fe/C is changed from 4 to 10,the reaction speed is slightly reduced, when Fe/C is changed from 10 to 20,the reaction speed is obviously reduced; the reaction speed is gradually reduced when pH is changed from acidity to alkalinity; the influence of reaction temperature is not obvious; The iron fillings particle size is bigger, the reaction speed is slower. Compare the wastewater with H2O2 to the wastewater without H2O2,it can be known that H2O2 has not obvious effect of the degradation rate ,but the effect of reaction speed is obvious. The research dealing with dye Acid Red B waste water is of great realistic significance, the removal rate of the acid red B dye could arrive at over 96%.
