[0029] In today's agricultural production activities, there is not only a large amount of agricultural water, but also domestic water for people, which also generates a large amount of sewage. The general treatment is to collect the sewage into underground pipes and discharge it into rivers and lakes, or to add a large amount of chemicals to remove impurities and pollutants. On the one hand, this causes great pollution to the environment, and on the other hand, it requires a large amount of capital cost.

[0030] In order to solve the above problems, the utility model proposes a contact oxidation pond system, which aims to provide a contact oxidation pond system with low pollution removal cost and capable of recycling sewage. Figures 1 to 4 The present invention is a schematic structural diagram of an embodiment of a contact oxidation pond system provided by the present invention.

[0031] Please refer to Figures 1 to 3The utility model provides a contact oxidation pond system 1000, comprising a contact oxidation pond 1, an aeration device 2 and an aerobic composite filler 3. The contact oxidation pond 1 is provided with a receiving tank 11 for receiving sewage; the aeration device 2 comprises a plurality of jet aerators 21, which are installed at the bottom of the contact oxidation pond 1 and arranged at intervals to allow the sewage to flow; the aerobic composite filler 3 is accommodated in the contact oxidation pond 1 to increase the attachment area of ​​microorganisms in the sewage.

[0032] In the technical solution of the utility model, the plurality of jet aerators 21 are installed at the bottom of the contact oxidation tank 1 and arranged at intervals to make the sewage flow and carry more oxygen in the air into the sewage. The aerobic composite filler 3 provides more attachment area for the microorganisms in the sewage, so that the microorganisms can accelerate the decomposition and treatment of pollutants in the sewage under the action of oxygen, thereby allowing the sewage to be recycled again and the pollution removal cost is lower.

[0033] For further information, please refer to Figure 3 The contact oxidation tank 1 is provided with a top plate 12 to form a receiving chamber 111 with the receiving tank 11 to seal the sewage. It is understandable that the sewage contains a lot of impurities and various odors will be generated during the decomposition of microorganisms. Therefore, before the sewage is completely treated, the contact oxidation tank 1 is provided with the top plate 12 to form a receiving chamber 111 with the receiving tank 11 to seal the sewage, so that the odor of the sewage will not be emitted.

[0034] For further information, please refer to Figure 3 The top plate 12 is provided with a fixing bracket 121, and the fixing bracket 121 includes a threaded steel bar 1211 and an I-beam 1212. The two ends of the threaded steel bar 1211 and the I-beam 1212 are respectively installed on the two opposite side walls of the accommodating groove 11, wherein the threaded steel bars 1211 are staggered relative to the I-beam 1212 and abut against each other. It can be understood that a pipe for intercepting sewage will be provided inside the accommodating chamber 111. During use, sewage will be discharged in a concentrated manner, resulting in excessive pressure inside the accommodating chamber 111, causing the top plate 12 to have a risk of cracking. Therefore, the top plate 12 is provided with the fixed bracket 121, and the fixed bracket 121 includes the threaded steel 1211 and the I-beam 1212. The two ends of the threaded steel 1211 and the I-beam 1212 are respectively installed on the opposite side walls of the accommodating groove 11, wherein the threaded steel 1211 is staggered relative to the I-beam 1212 and abut against each other. Through the staggered abutment of the threaded steel 1211 and the I-beam 1212, the pressure resistance of the top plate 12 is greatly improved, thereby avoiding the risk of the top plate 12 being broken by a large amount of sewage.

[0035] In addition, a mounting bracket 112 is also provided in the receiving tank 11, and the mounting bracket 112 extends from the top plate 12 to the bottom of the receiving tank 11, and is used to fix and install the aerobic combination filler 3. It can be understood that microorganisms need attachment points to decompose and evolve sewage. Generally speaking, the decomposition ability of wandering microorganisms is poor. If nothing is set in the receiving chamber 111, only the side walls and the bottom can provide attachment points for microorganisms, but only the attachment points in these places cannot make the number of microorganisms meet the standard, which leads to the contact oxidation tank 1 system 1000 decomposing and purifying sewage at a very slow speed. Therefore, the mounting bracket 112 is also provided in the receiving tank 11, and the mounting bracket 112 extends from the top plate 12 to the bottom of the receiving tank 11, and is used to fix and install the aerobic combination filler 3, thereby increasing more attachment points in space, thereby ensuring that there are enough microorganisms in the contact oxidation tank 1 to decompose and treat sewage, thereby greatly improving the treatment speed of sewage in the contact oxidation tank 1.

[0036] In addition, a manhole 122 is provided on the top plate 12. It is understandable that the multiple jet aerators 21 and the aerobic combination filler 3 provided inside the accommodating chamber 111 are consumables, and after being used for a certain period of time, they need to be manually repaired and replaced inside the accommodating chamber 111. Therefore, the manhole 122 is provided on the top plate 12 for maintenance personnel to conveniently enter the accommodating chamber 111, repair the multiple jet aerators 21 inside the accommodating chamber 111, and replace the aerobic combination filler 3.

[0037] In addition, please refer to Figure 2The aeration device 2 further includes an aeration main pipe 22 and an aeration branch pipe 23. The aerator 21 is connected to the aeration branch pipe 23. The aeration branch pipe 23 is connected to the aeration main pipe 22. The free end of the aeration main pipe 22 extends to the notch of the accommodating tank 11. It can be understood that the function of the jet aerator 21 is to make the sewage flow through the effect of jet agitation, so as to better bring oxygen in the air into the sewage, so as to accelerate the decomposition of the sewage by microorganisms through oxygen. However, this limits the speed at which the sewage can accommodate oxygen. Furthermore, the aeration device 2 also includes the aeration main pipe 22 and the aeration branch pipe 23. The aerator 21 is connected to the aeration branch pipe 23, and the aeration branch pipe 23 is connected to the aeration main pipe 22. The free end of the aeration main pipe 22 extends to the notch of the receiving tank 11. The air is brought into the receiving tank 11 through the aeration main pipe 22, and then the air is dispersed to each of the jet aerators 21 through the aeration branch pipe 23. Then, through the jet effect of the jet aerator 21, the air is injected into the sewage, providing sufficient oxygen for the microorganisms, further accelerating the decomposition and treatment speed of the sewage by the microorganisms.

[0038] In addition, please refer to Figure 1 , Figure 2 and Figure 4 , and also includes a sedimentation tank 4, which is arranged on the side of the contact oxidation tank 1 and is connected to the oxidation tank 1. It can be understood that after the decomposition treatment of the contact oxidation tank 1, the sewage is treated and a large amount of large particle impurities are contained in the water. Due to the presence of the jet aerator 21 in the contact oxidation tank 1, the sewage cannot be left standing, and thus it is impossible to separate the large particle impurities in the sewage. Therefore, the contact oxidation tank 1 system 1000 also includes the sedimentation tank 4, which is arranged on the side of the contact oxidation tank 1 and is connected to the oxidation tank 1. After the treated sewage in the contact oxidation tank 1 flows into the sedimentation tank 4 and is left to stand and precipitate, relatively clean water can be obtained, which can be further flowed into farmland or used for fishery breeding, etc., realizing the recycling of agricultural water and domestic water, and the cost of decomposition treatment is very low, with extremely high economic efficiency.

[0039] For further information, please refer to Figure 4The sedimentation tank 4 is provided with a guide tube 41, which extends from bottom to top and is erected in the sedimentation tank 4. It can be understood that when the treated sewage flows into the sedimentation tank 4, it is easy to disturb the treated sewage already in the sedimentation tank 4, affecting the static sedimentation process. In order to prevent the treated sewage flowing into the sedimentation tank 4 from disturbing the treated sewage already in the sedimentation tank 4, the sedimentation tank 4 is provided with the guide tube 41, which extends from bottom to top and is erected in the sedimentation tank 4.

[0040] For further information, please refer to Figure 4 , the sedimentation tank 4 is also provided with a guide bracket 42, which extends from the side wall of the sedimentation tank 4 and is connected to the guide tube 41. It can be understood that since the sediment is settled at the bottom of the sedimentation tank 4, the bottom of the guide tube 41 cannot contact the bottom of the sedimentation tank 4. Therefore, the installation of the guide tube 41, specifically, the sedimentation tank 4 is also provided with the guide bracket 42, which extends from the side wall of the sedimentation tank 4 and is connected to the guide tube 41. The guide bracket 42 is installed and fixed so that the bottom of the guide tube 41 does not contact the bottom of the sedimentation tank 4.

[0041] In addition, please refer to Figure 4 , a mud discharge pipe 43 is provided at the bottom of the sedimentation tank 4. It can be understood that the large particles contained in the treated sewage can be fertile organic mud after being precipitated in the sedimentation tank 4, which is the best and cleanest fertilizer for crop cultivation. In addition, the organic mud obtained after static precipitation in the sedimentation tank 4 also needs to be dug out in time, otherwise it will affect the sewage sedimentation inside the sedimentation tank 4. Therefore, a mud discharge pipe 43 is provided at the bottom of the sedimentation tank 4, which can be extracted by extraction equipment, further saving manpower.
