Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an aeration treatment device for organic industrial wastewater. Background Art

[0002] Organic industrial wastewater refers to industrial wastewater containing biodegradable or difficult-to-biodegrade organic matter, such as chemical wastewater, food wastewater, pharmaceutical wastewater, papermaking wastewater, etc. The treatment methods of organic industrial wastewater can be roughly divided into physical treatment, chemical treatment, physicochemical treatment and biological treatment1. Among them, biological treatment is the main method for treating organic industrial wastewater, which uses the metabolism of microorganisms to convert organic matter into harmless or low-toxic substances.

[0003] Biological treatment can be divided into aerobic biological treatment and anaerobic biological treatment. Aerobic biological treatment is the basic method for treating low-concentration easily degradable organic industrial wastewater by using aerobic microorganisms to oxidize organic matter into carbon dioxide, water and inorganic salts under aerobic conditions. Anaerobic biological treatment is the preferred method for treating high-concentration easily degradable organic industrial wastewater by using anaerobic microorganisms to reduce organic matter into methane, carbon dioxide and water under anaerobic conditions. However, the effluent after anaerobic biological treatment still contains a high concentration of organic matter, and generally needs to be treated by aerobic biological treatment to meet discharge standards.

[0004] Aeration is an important part of biological treatment. It is a process of injecting air into sewage to provide dissolved oxygen, promote the growth and metabolism of microorganisms, and thus improve the biochemical treatment efficiency of sewage. Aeration equipment is a device that achieves aeration. Existing mechanical aeration equipment has the disadvantages of high energy consumption, low oxygen utilization, and uneven gas distribution. Therefore, an aeration treatment device with relatively uniform gas distribution is designed. Utility Model Content

[0005] The utility model provides an aeration treatment device for organic industrial wastewater, which can realize the swing jet of the jet head, increase the stirring and mixing of the water body, make the oxygen evenly distributed in the water body, prevent the dead corner and short flow phenomenon in the pool, and improve the uniformity of sewage treatment.

[0006] An aeration treatment device for organic industrial wastewater comprises a sewage channel, characterized in that: the upper side of the sewage channel is fixedly connected to a support plate by symmetrical inclined rods;

[0007] A group of evenly arranged support columns are hinged on one side of the support plate, and the lower end of each support column is fixedly connected to a limit block, each limit block is passed through by a limit shaft, one end of each limit shaft is fixedly connected to one end of the cavity tube, and the two ends of the lower side of each cavity tube are fixedly connected to a gas channel, and each gas channel is fixedly connected to a group of evenly arranged nozzles.

[0008] As a further limitation of the present technical solution, an air inlet pipe is respectively arranged on the upper side of each cavity tube.

[0009] As a further limitation of the present technical solution, the other end of each of the limit shafts is fixedly connected to a T-shaped block, the vertical rod of each of the T-shaped blocks is hinged to the lower side of the moving rod, the two ends of the upper side of the moving rod are respectively bearing-connected to one end of a connecting rod, and the other ends of the two connecting rods are respectively bearing-connected to the support plate.

[0010] As a further limitation of the technical solution, the upper side of the support plate is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to the other end of one of the connecting rods.

[0011] As a further limitation of the technical solution, the spray head is a hollow sphere and has a circular hole penetrating transversely on its surface.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] The hollow spherical jet head can produce tiny bubbles, increase the gas-liquid contact area, improve the mass transfer rate and solubility of oxygen, promote the growth and metabolism of microorganisms, and improve the biochemical treatment effect of sewage;

[0022] The following is combined with Figure 1-Figure 5 The utility model is further described with implementation modes.

[0023] Embodiment 1: An aeration treatment device for organic industrial wastewater, comprising a sewage channel 3, the upper side of the sewage channel 3 being fixedly connected to a support plate 1 via symmetrical inclined rods 2;

[0024] A group of evenly arranged support columns 11 are hinged on one side of the support plate 1, and the lower end of each support column 11 is fixedly connected to a limit block 12, and each limit block 12 is passed through by a limit shaft 13, and one end of each limit shaft 13 is fixedly connected to one end of the cavity tube 6, and the two ends of the lower side of each cavity tube 6 are fixedly connected to the gas channel 5, and each gas channel 5 is fixedly connected to a group of evenly arranged nozzles 4.

[0025] An air inlet pipe 7 is disposed on the upper side of each cavity tube 6 .

[0026] The other end of each of the limit shafts 13 is fixedly connected to the T-shaped block 10, and the vertical rod of each of the T-shaped blocks 10 is hinged to the lower side of the moving rod 9. The two ends of the upper side of the moving rod 9 are respectively bearing-connected to one end of the connecting rod 14, and the other ends of the two connecting rods 14 are respectively bearing-connected to the support plate 1.

[0027] The upper side of the support plate 1 is fixedly connected to the motor 8 , and the output shaft of the motor 8 is fixedly connected to the other end of one of the connecting rods 14 .

[0028] Each of the air inlet pipes 7 is fixedly connected to an oxygen delivery device via a hose. Both the hose and the oxygen delivery device are prior art and will not be described in detail.

[0029] The working principle of the utility model is as follows: when organic industrial wastewater enters the sewage channel 3, the motor 8 starts to work, driving the connecting rod 14 to rotate, thereby driving the moving rod 9 to move in a circle, and then driving the T-shaped block 10 to move in a circle, the T-shaped block 10 drives the limit shaft 13 to move in a circle, the limit shaft 13 moves back and forth along the circular hole passing through the limit block 12 and drives the limit block 12 to rotate back and forth, and the limit shaft 13 finally drives the cavity tube 6 and the jet head 4 to swing in a circle for aeration;

[0030] When the cavity tube 6 and the nozzle 4 swing, the nozzle 4 will produce different angles in the horizontal and vertical directions, so that the ejected bubbles form different trajectories in the water body, increasing the relative movement of gas and liquid, improving the mass transfer efficiency and solubility of oxygen, promoting the growth and metabolism of microorganisms, and improving the biochemical treatment effect of sewage.

[0031] Embodiment 2: Based on the aeration treatment device for organic industrial wastewater provided in the first embodiment of the present application, the second embodiment of the present application proposes another aeration treatment device for organic industrial wastewater. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0032] Specifically, the difference of the organic industrial wastewater aeration treatment device provided in the second embodiment of the present application is that it also includes the following features: the jet head 4 is a hollow sphere and has a circular hole penetrating transversely on its surface.

[0033] The working principle of this embodiment is as follows: In this embodiment, the same parts as those in the first embodiment are not described in detail. The difference from the first embodiment is that when the nozzle 4 sprays bubbles, since the nozzle 4 is a hollow sphere and has horizontally penetrating circular holes on the surface, the sprayed bubbles are small, which increases the gas-liquid contact area, improves the mass transfer rate and solubility of oxygen, promotes the growth and metabolism of microorganisms, and improves the biochemical treatment effect of sewage.

[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
