[0032] Example 3

[0033] like Figure 1-5As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the oxygen demand control device 2 includes a water storage tank 21, an air inlet pipe 22, a constant temperature aeration device 23, an air outlet pipe 24, a water outlet pipe 25, a sealing cover 26, and a three-phase separator 27.

The aerator 232 is located on one side of the heat dissipation structure 231, the aeration tube 233 is located on one side of the aerator 232, the temperature sensor 235 is located on the other side of the heat dissipation structure 231, and the heater 234 is located on one side of the temperature sensor 235. A notch is provided between the aerator 232 and the aeration tube 233, and one side of the aerator 232 is detachably connected to one side of the aeration tube 233 through the notch. A wire is provided between the temperature sensor 235 and the heater 234, and the input end of the heater 234 is electrically connected to the output end of the temperature sensor 235 through the wire. Bolts are provided between the heat dissipation structure 231 and the aerator 232, and the other side of the aerator 232 is fixedly connected to one side of the heat dissipation structure 231 through the bolts.

[0034] In this embodiment, the oxygen demand inside the treatment equipment can be effectively controlled so that the oxygen content inside it will not fluctuate. When the water of the treatment equipment flows into the water storage tank 21, the three-phase separator 27 separates the water and the oxygen, and the oxygen is discharged from the outlet pipe 24 through the generated pressure difference. If the oxygen content inside the water storage tank 21 is too low, the aerator 232 can be used to timely oxygenate the water storage tank 21 to make the oxygen content inside and outside the tank consistent. The oxygen demand is easily affected by temperature, and the temperature inside the water storage tank 21 can be sensed by the temperature sensor 235. If the temperature is low, the heater 234 can be heated in time and a large amount of heat can be dissipated by the heat dissipation structure 231, thereby increasing the temperature inside the tank. In this way, the oxygen demand inside the equipment can be controlled at any time.

[0035] The working principle of the kitchen waste treatment equipment with oxygen demand control device is described in detail below.

[0036] like Figure 1-5As shown, when this kitchen waste treatment equipment is in use, the sewage after cleaning can be filtered through the filtering device 5, and the internal stains can be effectively treated, so as to obtain a clean water source, and avoid direct discharge of sewage to pollute the environment. The sewage after cleaning flows into the cylinder 51 through the pipe 54, and the garbage and oil stains in the sewage are filtered through the filter 52, and the solid particles inside the sewage are adsorbed by the activated carbon 53 on the upper end of the filter 52. The clean water source passes through the filter 52 and is discharged from the drain pipe 57 to the water circulation device 6. It is very practical and efficient, and the water circulation device 6 can reuse the sewage at the rear end of the filtration to avoid the loss of water resources, thereby reducing the water cost of the treatment equipment. The circulating water pump 67 draws the water flowing out of the drain pipe 57 into the first circulating pipe 65. In this process, the condenser 66 collects the drainage in the pipe to reduce the loss of water during transportation. The water flows from the first circulating pipe 65 into the collecting water Box 61, open valve 64, and the water in the water collecting box 61 flows into the treatment equipment again through the second circulation pipe 63, so as to facilitate its secondary use. The oxygen demand inside the treatment equipment can be effectively controlled by the oxygen demand control device 2, so that the oxygen content inside the treatment equipment will not fluctuate. When the water from the treatment equipment flows into the water storage tank 21, the water and oxygen are separated by the three-phase separator 27, and the oxygen can be discharged from the outlet pipe 24 through the generated air pressure difference. If the oxygen content inside the water storage tank 21 is too low, the aerator 232 can be used to oxygenate the water storage tank 21 in time to make the oxygen content inside and outside the tank body consistent. The oxygen demand is easily affected by temperature, and the temperature inside the water storage tank 21 can be sensed by the temperature sensor 235. If the temperature is low, the heater 234 can be heated in time and a large amount of heat is emitted by the heat dissipation structure 231, so that the temperature inside the tank body increases, so that the oxygen demand inside the equipment can be controlled at any time.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
