Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, in particular to a wastewater deodorization device based on an optimized structure of a microbial carrier. Background Art

[0002] When wastewater is being treated, it will enter the sedimentation tank. The larger solid impurities in the wastewater will naturally settle to the bottom of the tank, and then the wastewater will stand and stratify. The upper layer does not contain larger impurities. When the organic matter in the wastewater decomposes under anaerobic conditions, it will produce various odorous substances. At this time, relevant microorganisms are added to the wastewater. The microorganisms decompose the odor-causing substances in the wastewater through their own metabolic activities. Compared with chemical deodorization methods, microbial deodorization does not require the use of a large amount of chemical agents, avoiding the environmental pollution caused by chemical agents and potential harm to human health.

[0003] However, wastewater contains some heavy metal ions, which will change the permeability of cell membranes, causing heavy metal ions to enter the cells, leading to metabolic disorders of microorganisms, growth inhibition, and even death, thereby affecting the efficiency of microbial wastewater treatment.

[0031] The present invention will be further described below with reference to the embodiments. Example

[0032] See also Figures 1-9 The present invention provides a technical solution: a wastewater deodorization device based on an optimized structure of a microbial carrier, comprising:

[0038] The spraying pipe 321 includes a connecting frame 3211, a spraying pipe 3212 and a connecting pipe 3213. The connecting frame 3211, the spraying pipe 3212 and the connecting pipe 3213 are arranged in sequence from top to bottom. The connecting pipe 3213 is fixedly connected to the hollow tube 31. The spraying pipe 3212 is rotatably connected between the connecting frame 3211 and the connecting pipe 3213, and the spraying pipe 3212 and the connecting pipe 3213 are connected to each other. A distribution hole 3214 is opened on the outer surface of the circumference of the spraying pipe 3212, and there are multiple distribution holes 3214 and they are distributed in an array along the central axis of the spraying pipe 3212.

[0042] The principle and advantages of the wastewater deodorization device based on the optimized structure of microbial carriers:

[0043] Treatment of heavy metal ions in wastewater:

[0044] First, the staff transports the stationary wastewater from the outside through the equipment along the water inlet pipe 21 to the treatment barrel 2 (the wastewater in the treatment barrel 2 does not exceed the central axis position). After the pumping is completed, the staff opens the feeding part 25. At this time, the treatment reagent in the feeding part 25 (the treatment reagent uses sodium sulfide solution or other reagents that can precipitate heavy metal ions) will enter the hollow tube 31 along the conveying pipe. At the same time, the driving part 4 is started, and the stepping motor 41 in the driving part 4 drives the driving wheel 42 to rotate slowly and intermittently. Under the cooperation of the synchronous belt, the driven wheel 43 will drive the hollow tube 31 in the treatment barrel 2 to rotate synchronously. When the hollow tube 31 drives the spray pipe 3212 to rotate synchronously, When one of the connecting tubes 3213 just exceeds the horizontal position and continues to rotate upward, the gravity of the counterweight block 3233 in the connecting tube 3213 will gradually overcome the elastic force of the elastic part, so that the counterweight block 3233 drives the blocking block 3231 to gradually move downward along the inner wall of the connecting tube 3213. As the connecting tube 3213 rotates to a vertical position, the counterweight block 3233 will move the blocking block 3231 to the maximum distance along the inner wall of the connecting tube 3213 with the cooperation of its own gravity. Since the blocking block 3231 is provided with a slot 3232, the treatment reagent in the hollow tube 31 can enter the connecting tube 3213 along the slot 3232 and pass into the spray pipe 3212.

[0045] As the hollow tube 31 continues to rotate, the shielding plate 3215 on the outer periphery of the spraying tube 3212 will gradually move downward along the sliding rod on the outer periphery of the spraying tube 3212 with the cooperation of the counterweight rod 3217. When the connecting tube 3213 moves to the vertical position, the counterweight rod 3217 will move the shielding plate 3215 to the maximum distance. At this time, the through hole 3216 on the shielding plate 3215 will be aligned with the material distribution hole 3214 on the spraying tube 3212 to form a discharge channel, so that the treatment reagent in the hollow tube 31 will be sprayed from the discharge channel into the treatment barrel 2. As the hollow tube 31 continues to rotate, the spray tube 3212 will rotate synchronously from a vertical position along the rotation direction of the hollow tube 31. At this time, the bevel gear 3218 on the spray tube 3212 will engage with the ring gear 3219 in the processing barrel 2, and then the hollow tube 31 will rotate at high speed (due to the transmission ratio between the bevel gear 3218 and the ring gear 3219, when the bevel gear 3218 and the ring gear 3219 engage with each other, the bevel gear 3218 will drive the spray tube 3212 to rotate at high speed), thereby spraying the treatment reagent into the processing barrel 2.

[0046] Collection of precipitate:

[0047] When the sulfur ions in the sodium sulfide come into contact with the heavy metal ions in the wastewater (heavy metal ions include lead, mercury and cadmium), they will react with each other to form precipitates (the precipitates are lead sulfide, cadmium sulfide and mercury sulfide). Since the collecting bucket 322 is always in contact with the inner wall of the treatment barrel 2, the precipitates will be deposited at the bottom of the wastewater. As the collecting bucket 322 moves, the precipitates can be collected in the collecting bucket 322 (the outer edge of the collecting bucket 322 adopts a tapered design, which gradually becomes thinner from the main body to the edge, so that when it rotates, it can reduce the impact on the water body. At the same time, the collecting bucket 322 and the material distribution rack are The rounded edge of the round rod design allows the water to flow around more smoothly, preventing the collection bucket 322 from muddying the wastewater). As the hollow tube 31 continues to rotate, the collection bucket 322 will rotate to the impurity treatment box 23. When the collection bucket 322 is no longer in contact with the inner wall of the treatment barrel 2, the return spring 3221 in the connecting frame 3211 loses its external restriction and, under the action of its own elastic force, pushes the collection bucket 322 into the impurity treatment box 23. At the same time, the magnetic part on the outer surface of the impurity treatment box 23 generates an adsorption force on the separation frame 3222. At this time, the separation frame 3222 will move along the rotating shaft. The rotation occurs, so that the lower part of the separation frame 3222 will separate from the collecting bucket 322 by a certain angle. At this time, the sediment in the collecting bucket 322 will fall into the impurity collection box 11. As the hollow tube 31 rotates again, the collecting bucket 322 will continue to rotate. When the collecting bucket 322 just contacts the inner wall of the processing barrel 2 (the inner wall of the processing barrel 2 is provided with a notch and the connection with the inner wall of the impurity processing box 23 is designed in an arc shape, when the collecting bucket 322 moves to the arc position, the collecting bucket 322 can naturally transition to the processing barrel 2, and the collecting bucket 322 and the separation frame 3222 are close to the inner wall of the processing barrel 2. Elastic parts are provided on one side of the wall to avoid interference during the period and affect the normal rotation of the collecting bucket 322). The collecting bucket 322 is squeezed by the inner wall of the treatment barrel 2 again. At this time, the collecting bucket 322 will move to the inside of the connecting frame 3211 again, and the reset spring 3221 is compressed. At the same time, the separation frame 3222 will be reset under the squeezing of the inner wall of the treatment barrel 2, and form a "whole" with the collecting bucket 322 again. In this way, the precipitate formed by heavy metal ions in the wastewater can be collected in the impurity collection box 11, which is convenient for the staff to centrally process the relevant impurities.

[0048] It is worth noting that as the driving unit 4 drives the hollow tube 31 to rotate, when the connecting tube 3213 rotates to a horizontal position, the counterweight block 3233 and the blocking block 3231 are in a "closed" state in the connecting tube 3213, and the treatment reagent in the hollow tube 31 will not enter the connecting tube 3213. As the connecting tube 3213 gradually rotates from a horizontal state to a vertical state, the gravity of the counterweight block 3233 itself will gradually overcome the elastic force of the elastic part. At this time, the connecting tube 3213 is gradually connected with the hollow tube 31. When the connecting tube 3213 is completely rotated to a vertical state, the counterweight block 3233 completely overcomes the elastic force of the elastic part, and the blocking block 3231 will move downward to the maximum distance until the slot 3232 leaks out. At this time, the connecting tube 3213 is completely connected with the hollow tube 31, and the treatment reagent in the hollow tube 31 will be sprinkled into the treatment barrel 2 through the distribution hole 3214 on the spray pipe 3212. When the connecting pipe 3213 gradually rotates from a vertical position to another horizontal position, the connecting pipe 3213 and the hollow tube 31 remain in a connected state under the cooperation of the weight of the counterweight 3233. As the connecting pipe 3213 continues to rotate, the weight of the counterweight 3233 will drive the blocking block 3231 to move downward, and in conjunction with the elastic force of the elastic member, it can gradually "close" the connecting pipe, so that the treatment reagent in the hollow tube 31 will not enter the connecting pipe. Similarly, the shielding plate 3215 and the counterweight rod 3217 on the injection pipe 3212 can also "open" or "close" the distribution hole 3214 according to the rotation of the injection pipe 3212. When the shielding plate 3215 gradually blocks the distribution hole 3214, it can prevent wastewater from flowing back into the injection pipe 3212 and contaminating the treatment reagent.

[0049] Microbial administration:

[0050] When the treatment of heavy metal ions in the wastewater is completed, the feeding part 25 will feed clean water into the hollow tube 31 to clean the inner wall of the hollow tube 31, the connecting tube 3213 and the spraying tube 3212. The cleaned water will be discharged into the treatment barrel 2. After the flushing is completed, the feeding part 25 will transport the solution containing microorganisms into the hollow tube 31. With the cooperation of the feeding part 3, the solution containing microorganisms will be sprinkled into the treatment barrel 2, so that the microorganisms will decompose the odor-causing substances in the wastewater through their own metabolic activities. After the treatment is completed, the staff can discharge the treated wastewater through the outlet pipe 22.

[0051] The present invention adopts the feeding part 3, which has the following advantages:

[0052] Advantage 1: Sodium sulfide reagent is first added into the treatment barrel 2 through the feeding part 3, so that heavy metal ions can be combined with it to form a precipitate. After the heavy metal ions in the wastewater are removed by sodium sulfide precipitation, the environmental toxicity for the survival of microorganisms is greatly reduced, avoiding excessive concentration of heavy metal ions in the wastewater, which leads to the inability to grow and reproduce normally of microorganisms. At the same time, the sulfur element in sodium sulfide can be used by certain microorganisms, further improving the deodorization efficiency of microorganisms in wastewater.

[0053] Advantage 2: During the rotation, the collecting bucket 322 always fits with the inner wall of the treatment barrel 2. As the collecting bucket 322 moves, the sediment can be collected in the collecting bucket 322. When the collecting bucket 322 rotates to the impurity treatment box 23, the return spring 3221 in the connecting frame 3211 will push the collecting bucket 322 into the impurity treatment box 23. With the help of the magnetic part, the separation frame 3222 will be separated from the collecting bucket 322 at a certain angle. At this time, the sediment in the collecting bucket 322 will fall into the impurity collection box 11, avoiding the sediment from affecting the microorganisms in the wastewater, so that the microorganisms cannot fully contact with the odor substrate in the wastewater. In addition, the collection and treatment of the sediment is realized through the feeding action, with a high degree of automation, which reduces manual operation and improves the efficiency of wastewater deodorization.

[0054] Advantage three: sodium sulfide reagent, clean water and solution containing microorganisms are transported into the hollow tube 31 in sequence through the feeding part 25, which can achieve switching without stopping the machine, increasing the practicality of the device, and after the clean water enters the wastewater, the concentration of sulfur ions in the wastewater can be reduced, avoiding excessive sulfur ion concentration that affects the activity of microorganisms.

[0055] Advantage four: the baffle 3215 on the spray pipe 3212 can "open" or "close" the distribution hole 3214 according to the rotation of the spray pipe 3212 and the counterweight rod 3217. When the baffle 3215 gradually blocks the distribution hole 3214, it can prevent wastewater from flowing back into the spray pipe 3212, thereby contaminating the relevant solution in the hollow tube 31 and affecting the efficiency of microorganisms in deodorizing the wastewater.

[0056] Advantage five: by setting up multiple groups of spray pipes 321, when one group of spray pipes 321 is damaged, the other groups can still work without stopping for rectification, avoiding the possibility that the already prepared reagents and microbial solution agents may become ineffective or need to be readjusted due to long-term storage, resulting in waste of resources. At the same time, when the spray pipe 321 drives the collection bucket 322 to rotate slowly in the treatment barrel 2, it helps gas exchange in the wastewater. In the process of microbial deodorization, the supply of oxygen is crucial for aerobic microorganisms. Slow stirring can make the oxygen in the air better dissolve in the wastewater, providing sufficient oxygen for aerobic microorganisms. At the same time, gases such as carbon dioxide produced by the decomposition of odorous substances can also be discharged into the air in time through stirring.

[0057] Advantage six, as the hollow tube 31 rotates, when the connecting tube 3213 rotates to a vertical state, the counterweight block 3233 drives the blocking block 3231 to move to the maximum stroke, and the connecting tube 3213 is completely connected with the hollow tube 31. At this time, the solution in the hollow tube 31 is spilled through the distribution hole 3214 on the spray tube 3212, and the bevel gear 3218 on the spray tube 3212 will engage with the ring gear 3219, thereby driving the spray tube 3212 to rotate at a high speed. The spray tube 3212 sprays while rotating, which can expand the spraying range. At the same spraying flow rate, it can cover more areas, thereby reducing the overall spraying time.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
