The testing method comprises the following steps: firstly, starting an oxygen dissolving system for 2 hours, dissolving oxygen in water in the fishpond 6 once, waiting for 5 minutes, and sampling and measuring the dissolved oxygen value in the middle of the water body of the fishpond 6. Because the test range of the dissolved oxygen meter is only 20mg/L, the dissolved oxygen meter is easy to be exposed, and the following test method is adopted: 1 part of mountain stream water is taken to measure an oxygen dissolving value A, 1 part of oxygen dissolving water to be measured in ase:Sub>A fishpond is taken, the oxygen dissolving value of the oxygen dissolving water to be measured in the fishpond cannot be measured due to the fact that the riot meter cannot be measured, the 1 part of mountain stream water is poured into the oxygen dissolving water to be measured in the fishpond, the mixed oxygen dissolving value is measured as B after being uniformly stirred, and the oxygen dissolving value of the oxygen dissolving water to be measured is X=2B-A.

Calculating the dissolved oxygen value of the dissolved oxygen water (namely the dissolved oxygen water at the outlet of the dissolved oxygen water output pipe 5) entering the fishpond: when the mixed dissolved oxygen value B is 17.45 mg/L, the dissolved oxygen value X=2B-A=2×17.45-8.9=26 mg/L of the dissolved oxygen water at the outlet of the dissolved oxygen water output pipe 5.
