Total organic carbon (TOC) and chemical oxygen demand (CODCr) are indicators of the degree of organic pollution in water. At present, CODCr is mainly used as an evaluation index in China, and the detection method of CODCr is more complicated and time-consuming than TOC. In this paper, it uses the Micro-Pressure Inner-Loop Bioreactor (MPR) to treat urban sewage, studies the treatment effect of MPR on organic pollutants, and further analyzes the correlation between TOC and CODCr. TOC and CODCr of municipal wastewater and MPR treated effluent were measured by total organic carbon analyzer and dichromate method respectively, and the degree of organic pollution of water samples was analyzed. The results showed that the average removal rates of TOC and CODCr in municipal wastewater were 83.54% and 90.81%, respectively. The theoretical correlation coefficient between TOC and CODCr in experimental raw water was only 0.7322. After MPR treatment, the correlation coefficient increased to 0.9534. For water samples with fixed contaminants and stable contents, TOC can be used to calculate water CODCr by linear fitting relationship.
