摘要：Chromium plating waste water contains a large number of heavy metal ions, some organic and inorganic substances and other harmful substances. After comprehensive comparison and measurement, Iron- carbon micro-electrolysis was adopted to treat it. The influence of various variables including iron/carbon ratio, pH and reaction time, on the treatment effect of chrome-containing wastewater was studied. As for results, the removal rate of Cr6+ reached 65.98%, 73.24%, 95.37% respectively when the iron/carbon was 1:1, pH was 3, reaction time is 20mins. At last, the experiment was done under these three optimal conditions. Under the optimal conditions, the removal rate of Cr6+ attained 97.38% according to the outcome.
