Rapid detection method of COD in organic sewage

The invention provides a rapid detection method for COD in organic sewage, comprising the following steps: 1) preparing a high-sluggishness stainless steel packed column: 2) preparing a standard template and measuring a sample: 2.1) respectively taking 6-8 comparison samples for a sewage discharge port to be detected according to different discharge times, respectively conveying the measured comparison samples into a gas chromatograph as standard samples, recording peak areas of the comparison samples, and making a standard curve method standard sample template; and sample measurement: takinga COD sample to be detected from the sewage discharge port in 2.1, detecting the COD sample to be detected in the gas chromatograph, and importing the standard curve method standard sample template established in 2.1 to directly calculate the COD content in the sample. By adopting the rapid detection method for COD in organic sewage provided by the invention, turbid samples can be detected, the detection sensitivity is hi
