Effect of sodium chloride on nitrobenzene wastewater treatment by iron carbon micro-electrolysis technology
In order to explore the removal efficiency and stability of pollutants in water using iron carbon micro-electrolysis technology in saline environment,taking nitrobenzene as the treatment object and using sodium chloride as salt source to construct a continuous treatment device for simulated wastewater,then,the optimal reaction condition was obtained through single factor experiments.The results showed that,the optimal condition for iron carbon micro-electrolysis technology treating nitrobenzene wastewater was as follows:the initial pH value of the wastewater was 3,the HRT was 2 h,the aeration rate was 1 L/min.Under the above condition,NaCl had a significant strengthening effect on the degradation of nitrobenzene by iron carbon micro-electrolysis,when the mass fraction of sodium chloride was 0.5%-1.5%,the removal rate of nitrobenzene could be increased by 20%-30%.
