摘要

The electrolysis method was used to treat chromium-containing wastewater. The effects of five factors including initial pH, electrolyte dosage, plate spacing, electrolysis voltage, and initial concentration on the degradation rate of chromium were investigated. The value range of each influencing factor is as follows: initial pH value is 3 ~ 11, electrolyte dosing amount is 0.5 ~ 3g, plate spacing is 1 ~ 3cm, and electrolytic voltage is 2 ~ 12V. Under the conditions of electrolysis for 2h, the degradation rate of chromium can reach 97.41%.
