Research on Micro-electrolysis Method to Treat the Chrome-Containing Steel Wastewater

摘要

Iron- carbon micro- electrolysis was applied in the treatment of the steel wastewater containing chromium, The effects of initial pH, stirring speed, Fe/C (quality), reaction time were investigated by single factor experiments. According to the results of the static experiments, the dynamic test is carried out in a fixed bed reactor composed of iron and carbon, the experimental results show that when the flow rate of less than 40 ml/min, the system can be continuously stable operation 6 h.
