Problems solved by technology

[0002] Sulfur-iron autotrophic denitrification technology is used in more and more applications in sewage treatment. The combination of the two can synergistically carry out deep denitrification of sewage. In the existing technology, the adequacy of the reaction needs to be verified and a reasonable ratio can be realized. At the same time, there is less involvement in the reaction control in the later stage of the reaction device that has been formed, and there is no precise control of the temperature and concentration changes in the reaction

Embodiment 1

[0047] Figure 1 ~ Figure 2A specific embodiment of the present invention is shown, a sulfur-iron autotrophic denitrification device, comprising an iron autotrophic denitrification bin 2 and a sulfur autotrophic denitrification bin 3; The water device is connected between the iron autotrophic denitrification bin 2 and the sulfur autotrophic denitrification bin 3; the top of the sulfur autotrophic denitrification bin 3 is provided with an outlet pipe 7; the outlet pipe 7 is provided with a gas concentration sensor , a gas flow sensor 8, a signal collector and a signal transmitter; the lower part of the sulfur autotrophic denitrification bin 3 is provided with a water outlet pipe 9; the signal transmitter transmits gas data information to the control platform.

[0048] The iron autotrophic denitrification bin and the sulfur autotrophic denitrification bin are independently designed, so that the reaction occurs independently and is independently controllable. At the same time, th...

Embodiment 2

[0066] A reaction control method for a sulfur-iron autotrophic denitrification device, comprising the following steps:

[0067] 1) Sewage is passed into the first hollow plate, and the sewage flows into the iron autotrophic denitrification chamber through the first outlet hole on the upper part;

[0068] 2) The denitrified liquid and the reaction gas go through the water inlet hole at the bottom to the second water outlet hole at the top and flow into the sulfur autotrophic denitrification chamber;

[0069] 3) After the reaction in the sulfur autotrophic denitrification chamber, the liquid is discharged through the outlet pipe, and the reaction gas is discharged through the exhaust pipe at the top;

[0070] 4) The control platform receives the gas flow and gas concentration data, and judges according to the gas data. If the gas concentration is greater than or equal to the threshold and the gas flow is lower than the threshold, it is judged that the pipeline is blocked and nee...
