| Abstract: | This paper discusses the use of Fast Airtight Catalysis and Digestion Method to determine the COD of wastewater.The influence factors of the digestion temperature,digestion time,determine range and type of waste water on the determination results are given in the paper.The best conditions to determine wastewater COD are gotten as follows: COD measurement range is 50～1 000 mg/L,digestion time is 60min,digestion temperature is 150 ℃.The measured results are compared with the national standard method with the relative error<5%. |
