It pointed out that Acid Kali Permanganate method was common method to measure chemical oxygen consumption (COD) in water. Several methods of measuring COD were compared and analyzed experirnentally, combined with working experience, and some operating sug-gestions were proposed, so as to make measured result error reduce to minimum.
