Wires 3 are fixedly provided on the front and side of the total nitrogen analyzer 10, and the wires 3 are fixedly connected to the electromagnetic valve 902 and the circulation pump 12.

[0024] Specifically, a water inlet pipe 101 penetrating the side wall of the carbon source reaction tank 1 is fixedly connected to the left side of the carbon source reaction tank 1, and is used to introduce sewage into the carbon source reaction tank 1. A carbon source conduit 2, a water quality analyzer 4 and a reflux pipe 11 are fixedly connected to the top plate of the carbon source reaction tank 1. A carbon source metering pump 201 is fixedly installed on the carbon source conduit 2. A wire 3 is fixedly connected to the carbon source metering pump 201, and the other end of the wire 3 is connected to the water quality analyzer 4. A detection head 5 located in the inner cavity of the carbon source reaction tank 1 is connected to the top of the water quality analyzer 4, so that after the detection head 5 detects the water quality of the sewage, the data is transmitted to the water quality analyzer 4, and then the water quality analyzer 4 transmits the signal after processing to the carbon source metering pump 201, thereby controlling the opening and closing time of the carbon source metering pump 201. In order to control the dosage of the carbon source, a water pipe 6 is fixedly connected to the right side of the carbon source reaction tank 1, and a pressure pump 601 is fixedly installed on the water pipe 6. The other end of the water pipe 6 is fixedly connected to the organic nitride reaction tank 7, so that after the sewage treatment in the carbon source reaction tank 1 is completed, it will enter the organic nitride reaction tank 7 through the water pipe 6 for secondary treatment. An oxidant conduit 701 and an organic nitride detector 8 are fixedly connected to the top plate of the organic nitride reaction tank 7, an oxidant metering pump 702 is fixedly installed on the oxidant conduit 701, and a wire 3 is connected to the oxidant metering pump 702, and the other end of the wire 3 is connected to the organic nitride detector 8. Similarly, a detection head 5 is provided at the bottom of the organic nitride detector 8 and is located at the organic nitride detector. The interior of the reaction tank 7 is used to detect the content of organic nitrogen compounds in the sewage in the organic nitrogen compound reaction tank 7, thereby transmitting a signal to the oxidant metering pump 702 to turn the oxidant metering pump 702 on and off, and controlling the input amount of oxidants such as potassium sulfate, so that ammonia, ammonium salts, nitrites and other organic nitrogen compounds in the sewage in the organic nitrogen compound reaction tank 7 are converted into nitrates.

[0025] The working principle and use process of the utility model are as follows: first, the sewage is introduced into the carbon source reaction tank 1 from the water inlet pipe 101, and the detection head 5 in the carbon source reaction tank 1 will detect the water quality and transmit the signal to the water quality analyzer 4. After processing the signal, the water quality analyzer 4 provides the signal to the wire 3 to transmit it to the carbon source metering pump 201, and the start time of the carbon source metering pump 201 is controlled, thereby controlling the input amount of the carbon source. When the reaction in the carbon source reaction tank 1 is completed, the pressure pump 601 is started to allow the sewage to provide the water pipe 6 to enter the organic nitride reaction tank 7. The detection head 5 in the organic nitride reaction tank 7 will start to detect the content of organic nitrides in the sewage, thereby transmitting the signal to the organic nitride detector 8, and then from the organic nitride detector 8 to the oxidant metering pump 702, and the start time of the oxidant metering pump 702 is controlled, thereby controlling the input amount of the oxidant. When the reaction in the organic nitrogen compound reaction tank 7 is completed, the pressure pump 601 on the other side of the organic nitrogen compound reaction tank 7 can be started to control the sewage to enter the sewage detection tank 9. Then the detection head 5 in the sewage detection tank 9 will start to detect whether the total nitrogen content in the sewage detection tank 9 meets the discharge standard. When the discharge standard is met, the total nitrogen analyzer 10 will transmit an opening signal to the electromagnetic valve 902, so that the sewage is discharged from the outlet pipe 901. When it is detected that the total nitrogen content does not meet the discharge standard, it will transmit an opening signal to the circulation pump 12, so that the sewage is provided to the reflux pipe 11 to flow back to the carbon source reaction tank 1 for further treatment until the sewage meets the discharge standard, thereby realizing automatic control of the carbon source and oxidant input amounts, and at the same time, the sewage that does not meet the standard can be returned for further treatment in time, avoiding imperfect sewage treatment due to improper manual operation.
