[0028] refer to Figure 1 and Figure 2The sewage treatment system includes a pretreatment water tank 10, a sewage treatment tank 20, a water delivery component 30, a heating component 40, a stirring component 50, and a catalytic material pipeline 60; wherein, the pretreatment water tank 10 is provided with a pretreatment water cavity 11 for accommodating sewage; the pretreatment water tank 10 is provided with a water inlet pipe 12 for inputting sewage into the pretreatment water cavity 11; the sewage treatment tank 20 is provided with a plurality of sewage treatment areas; the water delivery component 30 includes a water delivery pipeline 31 and a first pump 32; the first pump 32 is placed in the pretreatment water cavity 11, one end of the water delivery pipeline 31 is connected to the water outlet of the first pump 32, and the other end is passed into the sewage treatment tank 20; the heating component 40 is arranged in the pretreatment water cavity 11 The bottom of the water chamber 11 is used to heat the sewage; the stirring assembly 50 includes a stirring blade 51, a stirring shaft 52, and a driving element 53; the stirring blade 51 is horizontally arranged at an upper position close to the heating assembly 40; the driving element 53 is set at the top of the pretreatment water tank 10; the upper end of the stirring shaft 52 is connected to the driving element 53, and the lower end is connected to the stirring blade 51; under the drive of the driving element 53, the stirring blade 51 rotates to drive the water to flow downward through the heating assembly 40; the catalytic material pipeline 60 is used to input catalytic material for sewage treatment into the pretreatment water chamber 11; the discharge port 61 of the catalytic material pipeline 60 is set between the heating assembly 40 and the stirring blade 51.

[0029] Specifically, the sewage treatment system includes a pretreatment water tank 10 and a sewage treatment tank 20. The sewage first enters the pretreatment water tank 10 through the water inlet pipe 12, and after being pretreated by the device in the pretreatment water tank 10, enters the sewage treatment tank 20 for the next sewage treatment process. The water delivery component 30 is used to transport the pretreated sewage in the pretreatment water tank 10 to the sewage treatment tank 20. The first pump 32 is placed in the pretreatment water chamber 11, and one end of the water delivery pipeline 31 is connected to the water outlet of the first pump 32, and the other end is connected to the sewage treatment tank 20. The first pump 32 draws sewage from the pretreatment water tank 10 and discharges it into the water delivery pipeline 31. The sewage reaches the sewage treatment tank 20 through the water delivery pipeline 31. In one embodiment of the present application, the sewage treatment system also includes a water quality monitor, and the water quality monitor 110 is provided on the water delivery pipeline 31. The water quality monitor 110 may include a variety of sensors that can be used to detect and analyze a variety of water quality indicators. The controller 90 is connected to the water quality monitor 110, so that real-time monitoring of the sewage output after pretreatment by the pretreatment water tank 10 can be achieved.

[0030] A pretreatment water chamber 11 is provided in the pretreatment water tank 10, and external sewage can enter the pretreatment water chamber 11 through the water inlet pipe 12. A heating component 40 is provided at the bottom of the pretreatment water chamber 11, which can heat the sewage around it so that the temperature around it is maintained within a predetermined range. The stirring blade 51 is horizontally arranged above the heating component 40 and opposite to the heating component 40. Under the drive of the driving element 53, the stirring blade 51 drives the water flow downward through the heating component 40 by rotation. Since the discharge port 61 of the catalyst pipeline 60 is arranged between the heating component 40 and the stirring blade 51, the catalyst discharged from the catalyst pipeline 60 can be mixed into the water flow and mixed with the sewage. When the water flow mixed with the catalyst passes through the heating component 40, it is heated by the heating component 40. At this time, the catalyst efficiently treats the harmful substances in the sewage flow at a suitable temperature.

[0031] Furthermore, a plurality of sewage treatment zones are provided inside the sewage treatment tank 20; in one embodiment of the present application, an anaerobic zone 21, an anoxic zone 22, and an aerobic zone 23 are provided inside the sewage treatment tank 20. It should be noted that in the anaerobic zone, anaerobic bacteria produce organic acids such as acetic acid and propionic acid by decomposing organic matter, while releasing gases such as methane, mainly to remove organic matter and reduce the impact of organic matter on subsequent processes. In the anoxic zone, nitrifying bacteria use organic acids and nitrogen in organic matter to carry out nitrification, converting ammonia nitrogen into nitrate nitrogen, mainly to remove the nitrogen load in sewage and reduce pollution to water bodies. In the aerobic zone, aerobic bacteria use nitrate nitrogen and organic matter to carry out denitrification, reducing nitrate nitrogen to nitrogen gas and releasing it into the atmosphere. At the same time, aerobic bacteria can also use phosphates to remove phosphorus, mainly to remove nutrients such as nitrogen and phosphorus, purify sewage, and meet discharge standards.

[0032] In one embodiment of the present application, the sewage treatment system is further provided with a storage container 62 for storing catalytic material; the feed end of the catalytic material pipeline 60 is connected to the storage container 62; a second pump 63 is provided on the catalytic material pipeline 60; driven by the second pump 63, the catalytic material pipeline 60 draws the catalytic material from the storage container 62 and discharges it from the discharge port 61. Driven by the second pump 63, the catalytic material in the storage container 62 enters the pretreatment water chamber 11 through the catalytic material pipeline 60. When the catalytic material needs to be fed into the pretreatment water chamber 11, the controller can control the second pump 63 to operate; when the catalytic material does not need to be fed into the pretreatment water chamber 11, the controller can control the second pump 63 to stop operating. In addition, in some embodiments, the controller can also precisely control the flow rate of the second pump.

[0033] In one embodiment of the present application, a flow-blocking structure 70 is further provided between the stirring blade 51 and the heating component 40, and the flow-blocking structure 70 can slow down the flow rate of the water flow; the outlet 61 of the catalyst pipeline 60 is specifically provided between the heating component 40 and the flow-blocking structure 70. The flow-blocking structure 70 can be used to block the water flow generated by the stirring blade 51 so that it flows slowly to the vicinity of the heating component 40, so that the heating component 40 has enough time to heat the water flow, and the catalyst has enough time to treat the sewage. In one embodiment of the present application, the flow-blocking structure 70 is a mesh structure or a porous plate structure. Furthermore, the flow-blocking structure 70 is a multi-layer structure, and each layer is composed of a mesh structure or a porous plate structure.

[0034] In one embodiment of the present application, a temperature detector 80 is further provided on the flow-blocking structure 70 for detecting the water temperature of the water flow at the flow-blocking structure 70. Figure 3 The sewage treatment system is further provided with a controller 90. The controller 90 is connected to the first pump 32 to control the speed at which the sewage is conveyed by the water delivery pipeline 31. The controller 90 is connected to the second pump 63 to control the speed at which the catalyst is conveyed by the catalyst pipeline 60. The controller 90 is connected to the temperature detector 80 to read the temperature measured by the temperature detector 80. The controller 90 is connected to the driving element 53 to control the rotation speed of the stirring blade 51. The controller 90 is connected to the heating assembly 40 to control the heating power of the heating assembly 40 so that the water temperature at the flow-blocking structure 70 remains within a set range. It should be understood that, driven by the driving element 53, the stirring blade 51 rotates to drive the water to flow downward through the heating assembly 40. The faster the driving element 53 drives the stirring blade 51 to rotate, the greater the water flow generated downward through the heating assembly 40. Conversely, the slower the driving element 53 drives the stirring blade 51 to rotate, the smaller the water flow generated downward through the heating assembly 40. Therefore, the controller can control the water flow through the heating assembly by controlling the output speed of the driving element.

[0035] Specifically, the controller 90 is connected to the first pump 32, the second pump 63, the temperature detector 80, the drive element 53, and the heating assembly 40, respectively. In an exemplary operation process, the controller 90 reads the temperature measured by the temperature detector 80 and can adjust the speed at which the drive element 53 drives the stirring blade 51 to rotate and the heating power of the heating assembly 40 according to the temperature. Furthermore, when the temperature measured by the temperature detector 80 is lower than the lower limit, the controller adjusts the drive element 53 to reduce the rotation speed of the stirring blade 51 to reduce the water flow rate and increase the heating power of the heating assembly 40. Conversely, when the temperature measured by the temperature detector 80 is higher than the upper limit, the controller adjusts the drive element 53 to increase the rotation speed of the stirring blade 51 to increase the water flow rate and reduce the heating power of the heating assembly 40. In this way, through the above adjustment process, the water temperature of the water flow at the flow-blocking structure 70 can be maintained within the set range. In addition, the controller 90 also adjusts the second pump 63 according to the rotation speed of the stirring blade 51, so that the speed at which the catalyst material is transported by the catalyst pipeline 60 matches the flow rate of the sewage to maintain the mixing ratio of the catalyst material and the sewage; specifically, when the rotation speed of the stirring blade 51 increases, the water flow rate increases, and the controller 90 adjusts the second pump 63 to increase the output speed of the catalyst material; conversely, when the rotation speed of the stirring blade 51 decreases, the water flow rate decreases, and the controller 90 adjusts the second pump 63 to decrease the output speed of the catalyst material.

[0036] In one embodiment of the present application, the pretreatment water tank 10 is further provided with a liquid level sensor 100 for detecting the liquid level within the pretreatment water chamber 11. The controller 90 is connected to the liquid level sensor 100 to obtain the liquid level. Furthermore, the controller 90 reads the liquid level within the pretreatment water chamber 11 from the liquid level sensor 100 and can provide a corresponding prompt when the liquid level within the pretreatment water chamber 11 exceeds a preset range.

[0037] In one embodiment of the present application, the water inlet pipe 12 is connected to a water inlet pipeline, and a third pump 121 is provided on the water inlet pipeline; the controller 90 is connected to the third pump to control the water inlet speed.

[0038] In a sewage treatment system, a heating assembly is located at the bottom of the pretreatment water chamber within the pretreatment water tank to heat the sewage. A stirring blade is positioned horizontally above and near the heating assembly, and a catalytic material pipeline is used to supply catalytic material for sewage treatment into the pretreatment water chamber. The discharge port of the catalytic material pipeline is located between the heating assembly and the stirring blade. Driven by a drive element, the stirring blade rotates, driving water downward through the heating assembly. Simultaneously, the discharge port of the catalytic material pipeline releases catalytic material, which mixes with the water. The heating assembly heats the water mixed with the catalytic material, allowing the catalytic material to efficiently treat harmful substances in the sewage at an appropriate temperature.
