Research on Treatment of Dyestuff Wastewater through Micro-Electrolysis

Experiments are conducted to illustrate some questions about treatment of dyestuff wastewater through micro-electrolysis.It is concluded that decolor efficiency is influenced by pH of wastewater,quantity of MnO2,initial wastewater concentration and medium material.It is then pointed out that decolor efficiency is higher when pH is 2~3,quantity of MnO2 10 g,and initial concentration 35 mg/L.Iron scrap is found to be better than steel scrap as medium of micro-electrolysis.This research provides basic data for the application of treating dyestuff wastewater through micro-electrolysis.
