摘要：For the ecological environment of serious pollution of wastewater containing chromium, made of aluminum plate electrocoagulation as chromium-containing wastewater treatment equipment, the effect of current density, treatment time, electrode spacing and other factors on the treatment effect. Experimental results show that the electro-flocculation process, a current density of 1.5, the initial pH of 6.0 and an electrolysis time of 1 hour, the plate spacing of 1cm optimal removal efficiency can reach 64%. In the electrocoagulation process, with increasing current density, electrolysis time, the metal ion removal increased; reduced electrode spacing, making the removal of heavy metal ions to achieve better results.
