Method for treating comprehensive electroplating wastewater

The invention relates to a method for treating comprehensive electroplating wastewater. The electroplating wastewater is separated and the recycling utilization rate of heavy metals resources can be improved by carrying out targeted treatment on each strand of separated water while improving the treatment efficiency. By using the micro-electrolysis function of iron and carbon, complex can be removed while removing COD (Chemical Oxygen Demand) and the biochemical property can be improved, which provides the guarantee for a subsequent biochemical reaction. By using the displacement action of the ion and the carbon, heavy metal ions in the water can be displaced and heavy metal resources can be recycled. Meanwhile, residual heavy metal ions in the water can be recycled by using the combining action of precipitating hydroxides and sulfides. On the basis, the water quality can meet the standard by using the ultrafiltration and reverse osmosis actions. The total hardness and the electric conductivity ...
