Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more specifically, to a biological deodorization device for sewage treatment. Background Art

[0002] In the daily operation of sewage treatment plants, a large amount of odor is generated in the sewage, causing great pollution to the air. The main reason for the odor of sewage is that it contains a large amount of organic matter. When these organic matter are decomposed by bacteria in the water under an oxygen-deficient environment, they will produce hydrogen sulfide, ammonia, mercaptans and other foul-smelling gases. As people's requirements for the environment increase, the odor problem of sewage treatment has been put on the agenda.

[0003] The common method of removing odor from sewage is to spray chlorine and ozone into the sewage through nozzles, and use oxidants to oxidize and decompose the organic matter that produces odor in the sewage. However, the oxidant can only be sprayed on the surface of the sewage using nozzles. If you want the oxidant to be fully mixed with the sewage, you need to stir it continuously. You need to wait for enough time for the oxidant to fully react with the organic matter in the sewage before discharging the sewage for subsequent treatment. This is a waste of time and cost. In addition, if you want to ensure that the oxidant and sewage are quickly and fully mixed, you need to increase the amount of oxidant, which will also increase the material cost.

[0004] Based on the above problems, we provide a biological deodorization equipment for sewage treatment. Summary of the invention

[0021] 4. The present application also installs a hollow frame and an aeration pipe on the side of the hole-digging slide, which can fill air into the water reservoir, so that bacteria can decompose organic matter in an aerobic environment and reduce the generation of odor. The hole-digging slide can push the aeration pipe to be continuously located in the water reservoir when it slides continuously, which can facilitate the uniform release of air into the water reservoir.

[0036] Reference Figures 1 to 4The mixing pool 13 is set to be circular, and a stirring shaft 1301 is rotatably installed at the center thereof. Two rotating frames 1302 are set on the stirring shaft 1301, and a plurality of cantilevers are evenly arranged in an radiating shape in the rotating frame 1302. The cantilever positions in the upper and lower rotating frames 1302 correspond to each other, and a plurality of spoiler rods 1303 are rotatably installed between the two corresponding cantilevers.

[0037] Embodiment 2

[0038] The difference from the first embodiment is that, referring to Figure 2 , Figure 4A hollow frame 1114 is also installed on one side of the hole-digging slide 1108, and a plurality of aeration pipes 1115 are connected to the bottom of the hollow frame 1114. The aeration pipes 1115 extend to the bottom of the water storage tank 11, and a plurality of aeration holes 1116 are opened on the side of the bottom end of the aeration pipe 1115. An air hose 1117 is also installed on the side of the hollow frame 1114. The air hose 1117 extends to the outside of the equipment box 1 and is connected to a blower (not shown in the figure). Further, in order to reduce the generation of odor in sewage , air can be filled into the hollow frame 1114 and the aeration pipe 1115 through the air hose 1117, and can be released into the sewage through the aeration holes 1116 set on the aeration pipe 1115, thereby providing an aerobic environment, so that when bacteria decompose organic matter, the generation of odor can be reduced. As the digging slide plate 1108 continues to slide, the aeration hole 1116 can be pushed to move continuously in the water tank 11, thereby facilitating the full mixing of air and sewage and increasing the oxygen content in the sewage.

[0039] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0040] The implementation principle of the biological deodorization equipment for sewage treatment in the embodiment of the present invention is as follows: when working, sewage can be first introduced into the equipment box 1 through the water inlet pipe 14. When the sewage enters the water storage tank 11, the filter 1102 installed in the vertical partition 1101 can filter the sewage, thereby removing impurities in the sewage. In order to avoid long-term use, impurities in the sewage will clog the filter 1102. A cleaning brush 1109 is provided on one side of the filter 1102. Through the cooperation of the speed change gear plate 1112 and the driven gear plate 1111, the Z-shaped folding rod 1110 can be pushed to rotate, and the Z-shaped folding rod 1110 can also cooperate with the hole-digging slide plate 1108 to drive the slide seat 1107 to slide continuously on the support rail 1106, and the slide seat 1107 can also push the cleaning brush 1109 to slide continuously, so that the impurities adhering to the filter 1102 can be cleaned off;

[0041] After being treated in the water storage tank 11, the sewage can be released into the graded treatment water tank 1203 in the reaction tank 12 via the primary water pump 1103 and the primary pipe fitting 1104. The graded treatment water tank 1203 is also provided with a water storage tank 1204. After the sewage is transported and overflows the water storage tank 1204 in the graded treatment water tank 1203, it can flow into the reaction tank 12 in the direction of the opening. The provided edge sealing 1205 can ensure that the sewage in the graded treatment water tank 1203 maintains a thin layer of flow. At this time, the oxidant solution sprayed by the atomizing nozzle 1207 can fully contact with the thin layer of sewage and mix quickly, which saves time and can greatly improve the treatment effect of the sewage. Afterwards, the cooperation of the secondary water pump 1201 and the secondary pipe fitting 1202 can release the sewage in the reaction tank 12 into the mixing tank 13 for further mixing reaction.

[0042] When the driving motor 1307 is working, it can push the active gear 1306 to rotate. Through the cooperation of the active gear 1306 and the passive gear 1305, the stirring shaft 1301 can be driven to rotate. When the stirring shaft 1301 drives the rotating frame 1302 to rotate, the spoiler rod 1303 installed between its cantilevers will rotate accordingly, and multiple spoiler plates 1304 are staggered on both sides of the spoiler rod 1303. As the spoiler rod 1303 continues to rotate in the mixing tank 13, the spoiler plates 1304 will also continue to change directions in the sewage, thereby pushing the sewage in the mixing tank 13 to produce irregular shaking and generate bubbles, further facilitating the mixing of the oxidant solution with the sewage and decomposing the organic matter in the sewage. The treated sewage can be discharged outward through the drain pipe 15 for the next step of treatment.
