Pre-treatment of Ramie Wastewater by Acidification and Iron Chip Inner-Electrolysis

Ramie wastewater was pretreated by acidification combined with icon chip inner-electrolysis in this paper.We discussed how pH adjustment and iron chip inner-electrolysis effect on the treatment of waste water.When the pH of wastewater was adjusted to 3.0 at room temperature,some organic matter would be removed from the water.As a consequence,CODcr and color rate would have a decrease in 83.58% and 27.22%,respectively.Then,under the most favorable working condition,we futher treated the wastewater by the above method,resulting in the removal rate of colors and CODcr reaching about 80% and 55%,repectively.The condition is as follows: pH=3.00,reaction time=40 min,mass ratio of FeC to wastewater=0.2,Fe:C=3,and the temperature=30℃.
