Continuous flow test device for testing carbon source

The utility model provides a continuous flow test device for a carbon source test. The continuous flow test device comprises a water inlet path, a carbon source path, a nitrogen source path, a gas path, a pipeline mixer, an oxidation ditch reactor, a first aerator, a second aerator and a third aerator, an outlet of the water inlet path is connected with an inlet of the oxidation ditch reactor; the oxidation ditch reactor comprises a first space, a first chamber, a fifth space and a sixth space which are communicated in sequence, and the sixth space is also communicated with the first space; the first aerator is mounted in the first chamber, and the second aerator and the third aerator are mounted in the sixth space; and the first aerator, the second aerator and the third aerator are connected in parallel on the air path. According to the utility model, the test device can perform a continuous flow simulation test, meets the long-term test requirement of a carbon source, and can realize tests under two working
