حذف خواست اكسيژن شيميايي (COD) فاضلاب با استفاده از روش الكتروشيميايي

Elimination of COD from Wastewater by Electrochemical Treatment

Many industrial wastewaters have been found to be highly saline content. Treatment of saline wastewater has not been easy. Biological methods are the tradition has revealed that the biological method may not be a good choice, primarily because of the inhibitory effect of high salinity on the microbial growth. With high saline content, the wastewater invariably has a rather high conductivity, because of the presence of anions and cations in the aqueous solution. Therefore, this method has been successfully employed with various types of industrial wastewater. In this paper, treatment of wastewaters by electrochemical method has been investigated. Also, the several aspects such as wastewater conductivity, PH and current density, temperature and concentration are explored to determine their effect on the treatment efficiency.
