Study on the Treatment of Nickel-Containing Wastewater by Spouted Bed Particulate Electro-Deposition

Abstract

In order to achieve the goal of purifying the nickel-containing waste,use the Spouted bed particulate electro-deposition to treat it . Experimental studies show that the best condition is the concentration of nickel influence 1000mg/L, the current is 15A, pH 4.5, and particle size of 1.8mm under the condition of blowing nitrogen. The removal rate of nickel can reach 74.77%. Nitrogen can effectively reduce the concentration of dissolved oxygen in the water and obtain a higher electro-deposition efficiency and current efficiency.
