Abstract

Electrochemical oxidation on the BDD electrode has caused extensive concern for non-biodegradable wastewaters treatment due to its favorable electrochemical property and high efficiency. Electrochemical oxidation of mustard tuber wastewater was performed on BDD electrode in this study. The effects of several parameters such as dilution ratio, initial pH value, current density and electrode gap were investigated in terms of the removal rate of COD and ammonia nitrogen (NH₃-N). Experimental results showed that electrochemical oxidation of mustard tuber wastewater on BDD electrode was an efficient advanced oxidation process. Under optimal operating conditions of dilution ratio (i.e. 1:2), current density (i.e. 50 mA·cm^-2), initial pH value (i.e. no adjustment) and electrode gap (i.e. 15 mm), the removal efficiency of COD and NH₃-N was 96.9% and 100%, respectively. Linear function y=0.435t is fit to the removal rate of COD, and R² is 0.9899. Polynomial function y=0.53+0.936t+0.031t²-3.46 × 10^-4t³ is fit to the removal rate of NH₃-N, and R² is 0.9956.
