[0001] The invention relates to the technical field of sewage treatment, and in particular to an aeration device for an aerobic sewage treatment pool and a treatment method. Background Art

[0002] At present, industrial wastewater usually needs to be treated before it can be discharged. The treatment methods for industrial wastewater include physical treatment, chemical treatment, physicochemical treatment and biological treatment. The biological treatment methods include anaerobic and aerobic methods. The aeration system is the most important link in the aerobic pool. The aeration method, distribution, and oxygen supply efficiency are directly related to the activity of the bacterial flora in the aerobic pool and the treatment effect of the wastewater.

[0003] At present, the most commonly used aeration methods in aerobic pools include perforated tube aeration and aeration disk aeration. Since the air source of aerobic pools is mostly high-temperature air, it will condense in the water and accumulate water. The condensed water causes water to accumulate inside the aeration disk, which in turn affects the aeration effect or causes the aeration disk to fail.

[0005] However, when the above-mentioned aeration device is in use, since the aeration disc sprays compressed air, the delivery pipeline will be subjected to the reaction force brought by the compressed air. Over time, the delivery pipeline will become loose, reducing the service life of the delivery pipeline and the efficiency of aeration. Summary of the invention

[0006] The purpose of the present invention is to provide an aeration device and a treatment method for an aerobic sewage treatment pool, which solves the technical problem that when the existing aeration device is in use, the aeration disc sprays compressed air, and when the compressed air is sprayed, the conveying pipeline will be subjected to the reaction force brought by the compressed air. After a long time, the conveying pipeline will loosen, reducing the service life of the conveying pipeline and reducing the efficiency of aeration.

A plurality of aeration plates are evenly distributed on each of the delivery pipes, and the delivery pipes are respectively connected to the transmission pipes and the aeration plates.

[0011] Wherein, the clamping mechanism includes a first clamping plate, a second clamping plate and a fixing member, the first clamping plate and the second clamping plate are respectively disassembled and arranged outside the conveying pipe, and the first clamping plate and the second clamping plate are connected by the fixing member.

[0012] Among them, the fixing part includes a fixing bolt and a fixing nut, the fixing bolt is detachably connected to the first clamping plate and the second clamping plate respectively, and passes through the first clamping plate and the second clamping plate respectively, and the fixing nut is detachably connected to the fixing bolt and is sleeved outside the fixing bolt.

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0029] First embodiment:

[0030] See also Figures 1 to 4 The present invention provides an aerobic sewage treatment pool aeration device, including an aerobic pool 101, an air compressor 102, an aeration plate 103, a filter 104, a limiting mechanism, a clamping mechanism, a connecting plate 105 and a spring 106, wherein the aeration plate 103 is connected to the air compressor 102 through a conveying pipeline, the limiting mechanism includes a first limiting plate 107, a second limiting plate 108 and a limiting member, the limiting member includes a limiting bolt 109 and a limiting nut 110, the conveying pipeline includes an air inlet pipe 111, a transmission pipe 112 and a conveying pipe 113, the clamping mechanism includes a first clamping plate 114, a second clamping plate 115 and a fixing member, the fixing member includes a fixing bolt 116 and a fixing nut 117.

[0031] In this embodiment, the compressed air generated by the air compressor 102 is delivered to the aeration plate 103 through the delivery pipeline and sprayed out from the aeration plate 103, so that the compressed air can be continuously delivered to the aerobic pool 101, and then sufficient oxygen can be continuously supplied to the bacteria in the aerobic pool 101 to ensure the biological activity of aerobic bacteria. By arranging the filter 104 in the aeration plate 103, the debris in the aerobic pool 101 can be filtered to prevent the debris from entering the aeration plate 103. At the same time, since the filter 104 is detachable, when the filter holes of the filter 104 are blocked, the filter 104 can be taken out of the aeration plate 103 to clear the blocked part of the filter 104. The delivery pipeline is clamped by the clamping mechanism so that the delivery pipeline can be cleaned during the process of delivering compressed air. The reaction force generated in the process will be transmitted to the clamping mechanism and then transmitted to the connecting plate 105 through the clamping mechanism, so that the connecting plate 105 will compress the spring 106 after being subjected to the force. At this time, since the spring 106 has a self-recovery effect, the spring 106 will repeatedly expand and contract. The repeated expansion and contraction of the spring 106 will remove the reaction force generated in the process of conveying compressed air, thereby avoiding the conveying pipeline from loosening when it is subjected to the reaction force brought by the compressed air for a long time, thereby ensuring the service life of the conveying pipeline, improving the aeration efficiency, and solving the technical problem that when the existing aeration device is in use, the conveying pipeline will be subjected to the reaction force brought by the compressed air when the compressed air is sprayed, and the conveying pipeline will loosen over time, reducing the service life of the conveying pipeline and reducing the aeration efficiency.

In the chute 118, the spring 106 is arranged between the connecting plate 105 and the aerobic tank 101 and is located in the chute 118. The filter screen 104 is evenly distributed with filter holes. The filter holes of the filter screen 104 can filter the debris in the sewage in the aerobic tank 101 to prevent the debris in the sewage from entering the aeration plate 103. The connecting plate 105 can slide up and down in the chute 118, so that the spring 106 can be expanded and contracted. The spring 106 has a self-restoring effect, so that the spring 106 will move in the direction of returning to its original position when the expansion and contraction force it is subjected to disappears.

[0033] Secondly, the first limit plate 107 is arranged outside the filter 104, and the second limit plate 108 is arranged outside the aeration plate 103.

The first limit plate 107 cooperates with the groove of the aeration plate 103 and can be inserted into the groove of the aeration plate 103. When the first limit plate 107 reaches the bottom of the groove of the aeration plate 103, the first limit plate 107 will contact the second limit plate 108.

[0035] At the same time, the air inlet pipe 111 is connected to the air compressor 102 and extends into the aerobic pool 101. The transmission pipe 112 is connected to the air inlet pipe 111 and is located in the aerobic pool 101. A plurality of the transmission pipes 113 are evenly distributed on the side of the transmission pipe 112 away from the air inlet pipe 111. A plurality of the aeration plates 103 are evenly distributed on each of the transmission pipes 113. The transmission pipes 113 are respectively connected to the transmission pipes 112 and the aeration plates 103. The air inlet pipe 111, the transmission pipe 112 and the transmission pipe 113 are all provided with control valves for controlling the air inlet pipe 111, the transmission pipe 112 and the aeration plates 103. The channel of the delivery pipe 113 is opened and closed, and the air compressor 102, the air intake pipe 111, the delivery pipe 112, the delivery pipe 113 and the aeration plate 103 are connected in sequence. When the channels of the air intake pipe 111, the delivery pipe 112 and the delivery pipe 113 are opened, the compressed air generated by the air compressor 102 can be delivered to the aeration plate 103 through the air intake pipe 111, the delivery pipe 112 and the delivery pipe 113, and sprayed out from the aeration plate 103, so that the compressed air can be continuously delivered to the aerobic pool 101, and then sufficient oxygen can be continuously supplied to the bacteria in the aerobic pool 101 to ensure the biological activity of the aerobic bacteria.

[0036] In addition, the first clamping plate 114 and the second clamping plate 115 are respectively disassembled and arranged outside the conveying pipe 113, and the first clamping plate 114 and the second clamping plate 115 are connected by the fixing member, the first clamping plate 114 has a protrusion, and the second clamping plate 115 has a groove, and the protrusion is inserted into the groove and is fixed in the groove.

[0037] Finally, the fixing bolt 116 is detachably connected to the first clamping plate 114 and the second clamping plate 115 respectively, and penetrates the first clamping plate 114 and the second clamping plate 115 respectively, the fixing nut 117 is detachably connected to the fixing bolt 116, and is sleeved outside the fixing bolt 116, the protrusion of the first clamping plate 114 and the groove of the second clamping plate 115 both have through holes, the fixing bolt 116 penetrates the protrusion of the first clamping plate 114 and the through holes of the groove of the second clamping plate 115 in sequence, the fixing nut 117 has a threaded hole, and the fixing bolt 116 has an external thread, the external thread of the fixing bolt 116 cooperates with the threaded hole of the fixing nut 117, so that the fixing nut 117 can move along the trajectory of the thread outside the fixing bolt 116, so that the fixing nut 117 can be tightened or loosened outside the fixing bolt 116.

[0038] When using an aerobic sewage treatment pool aeration device of this embodiment, after aligning the first limiting plate 107 with the groove of the aeration plate 103, the first limiting plate 107 is pushed into the groove of the aeration plate 103, so that the filter screen 104 can be placed in the aeration plate 103. When the first limiting plate 107 reaches the bottom of the groove of the aeration plate 103, the first limiting plate 107 will contact the second limiting plate 108. At this time, the limiting bolt 108 is pushed into the aeration plate 103. 09 are inserted into the through holes of the first limit plate 107 and the second limit plate 108 in sequence, and then the limit nut 110 is moved along the trajectory of the thread outside the limit bolt 109, so that the limit nut 110 can be tightened outside the limit bolt 109, so that the first limit plate 107 can be connected to the second limit plate 108, so that the filter 104 can be limited and fixed in the aeration plate 103, thereby realizing the installation of the filter 104.

[0039] The first clamping plate 114 and the second clamping plate 115 are placed outside the conveying pipe 113 in sequence, and the protrusion of the first clamping plate 114 is inserted into the groove of the second clamping plate 115. When the protrusion of the first clamping plate 114 reaches the inner bottom of the groove of the second clamping plate 115, the through hole of the first clamping plate 114 will be aligned with the through hole of the second clamping plate 115. At this time, the fixing bolt 116 is inserted into the protrusion of the first clamping plate 114 and the through hole of the groove of the second clamping plate 115 in sequence, and then the fixing nut 117 is moved outside the fixing bolt 116 along the trajectory of the thread, so that the fixing nut 117 can be tightened outside the fixing bolt 116, so that the first clamping plate 114 can be connected with the second clamping plate 115 to clamp and fix the conveying pipe 113.

[0040] Afterwards, the control valves on the intake pipe 111, the transmission pipe 112 and the delivery pipe 113 are operated in sequence to open the control valves on the intake pipe 111, the transmission pipe 112 and the delivery pipe 113, thereby opening the channels of the intake pipe 111, the transmission pipe 112 and the delivery pipe 113.

[0041] Subsequently, the air compressor 102 is started, so that the compressed air generated by the air compressor 102 during operation is transmitted to the aeration plate 103 through the air inlet pipe 111, the transmission pipe 112 and the transmission pipe 113 in sequence, and finally discharged from the aeration plate 103, so that the compressed air can be continuously delivered to the aerobic pool 101. By continuously delivering compressed air to the aerobic pool 101, sufficient oxygen can be continuously supplied to the bacteria in the aerobic pool 101 to ensure the biological activity of the aerobic bacteria.

[0042] In the process of the delivery pipe 113 delivering compressed air to the aeration plate 103, the compressed air has an impact force, which will generate a reaction force on the delivery pipe 113. At this time, the reaction force will be transmitted to the first clamping plate 114 and the second clamping plate 115 through the delivery pipe 113, and then transmitted to the connecting plate 105 through the first clamping plate 114 and the second clamping plate 115, so that the connecting plate 105 will compress the spring 106 after being subjected to force. At this time, since the spring 106 has a self-recovery effect, the spring 106 will repeatedly expand and contract. The repeated expansion and contraction of the spring 106 will remove the reaction force generated in the process of delivering compressed air, thereby avoiding the delivery pipeline from loosening when it is subjected to the reaction force brought by compressed air for a long time, thereby ensuring the service life of the delivery pipeline and improving the efficiency of aeration.
