Study on Treatment of High Chromium Industrial Wastewater by Pulsed Field-Coprecipitation Method

摘要

Chromium pollution poses a serious threat to the safety of human beings and animals. The traditional method of treating Chromium-containing wastewater is difficult to achieve the purpose of removing chromium depth, In this paper, the removal of chromium in high-chromium industrial wastewater was studied by pulsed electric field-coprecipitation method, and the removal efficiency of chromium was explored in action time, pulse voltage and duty cycle. The experimental results show that the action time is 4 min, the pulse voltage is 75V, the duty ratio is 10%, and the content of chromium is reduced from 34.9mg/L to 0.0028mg/L Chromium removal rate of up to 99.92%.
