Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of manganese and iron removal in infiltration gallery, and more particularly to a water taking and manganese and iron removal device based on an infiltration gallery. BACKGROUND

[0002] With the acceleration of urbanization, the demand for water in urban and rural areas is increasing, and the traditional water intake is facing multiple technical bottlenecks. On the one hand, it relies too much on a single surface water source and lacks efficient front-end pretreatment functions, resulting in the need for a large amount of potassium permanganate and other pre-oxidizing agents to be added to the water plant to remove manganese, iron and other pollutants in the water. However, this process not only significantly increases the cost of chemicals, but also significantly increases the subsequent treatment load, causing the frequency of filter backwashing to increase, equipment wear and tear to intensify and other problems. On the other hand, the surface water source is significantly affected by seasonal fluctuations, with high silt content (turbidity up to 200 NTU or more) in the rainy season and insufficient water in the dry season. The continuous decline in groundwater level leads to poor stability of single water source intake and reduced reliability of water intake in some areas, making it difficult to meet the growing demand for water.

[0003] In the prior art, surface water filtration generally follows the classic process of "coagulation - sedimentation - filtration". First, a coagulant such as polyaluminum chloride or aluminum sulfate is added to neutralize the charge and adsorb colloids to make suspended solids into flocs. After separation in a sedimentation tank, deep filtration is carried out through a quartz sand filter or an activated carbon filter. For dissolved manganese and iron ions in the water, an oxidizing agent such as potassium permanganate is added to pre-oxidize them so that they form precipitates and are then removed. The water in the infiltration gallery is generally removed by a combination of graded sand and anti-filtration geotextile to remove manganese and iron components.

[0004] In actual use, the prior art cannot simultaneously purify surface water or water in the infiltration gallery. The contact time between manganese ore and water is short, making it difficult to fully utilize catalytic oxidation and biological metabolism. This can lead to incomplete oxidation of manganese and iron ions in the water, low adsorption efficiency of organic matter and nitrogen and phosphorus pollutants, and difficulty in achieving the drinking water health standard.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a water taking and manganese and iron removal device based on an infiltration gallery. SUMMARY

[0041] Air inlet cover 205 is inverted horn shape, aeration assembly 2 is installed on the outer surface of bubble film 202 elastic pad 210, the inside of elastic pad 210 is provided with through hole communicated with bubble film 202, and the buffer performance of bubble film 202 is enhanced by absorbing external impact force through the elastic deformation of elastic pad 210, and it can be replaced by silicone rubber pad or composite material.

[0042] Please refer to Figure 8 Aeration assembly 2 also includes wind sensor 207 fixedly connected in the inside of air inlet chamber 204, and wind sensor 207 is an instrument for measuring wind speed, wind direction or wind grade, and it can be replaced by pressure sensor device; the inner cavity side wall of air inlet chamber 204 is fixedly connected with air pump 208, which can be replaced by centrifugal fan or micro vacuum pump device; one end of air pump 208 is fixedly connected with conveying pipe 209, and one end of conveying pipe 209 is communicated with the inner cavity of connecting pipe 206. The inside of collection seepage corridor main body 1 is installed with C25 concrete filter plate 101 and concrete frame 102, the side of collection seepage corridor main body 1 is installed with collection and seepage water delivery plate 103, the inside of collection and seepage water delivery plate 103 is fixedly connected with multiple upper layer partition plates 1048, middle partition plate and lower layer partition plate, water delivery groove 1047 is formed between upper layer partition plate 1048, middle partition plate and lower layer partition plate, multiple seepage holes 1046 are arranged in the inside of collection and seepage water delivery plate 103, and seepage pipe 1045 is embeddedly installed in the region corresponding to the top of collection seepage corridor main body 1.

[0043] Further, when the groundwater and the water in the collection and infiltration gallery pass through the manganese ore in the gabion 104, the catalytic oxidation characteristics of the manganese ore can be used to fully remove the oxidation precipitates of the divalent manganese ions and iron ions in the water under sufficient dissolved oxygen conditions. Meanwhile, when external air enters the connecting pipe 206 through the multiple trumpet-shaped air inlets 205, and the dispersed air is collected into the aeration pipe 203 through the multiple connecting pipes 206, the aeration pipe 203 delivers the air into the aeration ball 201 and the vibration piece 3. When the wind is insufficient or absent, the wind sensor 207 monitors the wind in real time, and once it is detected that the wind does not reach the set threshold, a signal is sent to the power supply and controller of the air pump 208 to start the air pump 208. The air generated by the air pump 208 is delivered into the aeration pipe 203 through the delivery pipe 209, and the air entering the aeration ball 201 is partially discharged through the bubble film 202. The bubble film 202 is made of microporous material, and the micropores are extremely small and uniformly distributed. The air is squeezed out of the micropores under pressure to form tiny bubbles. These tiny bubbles have extremely large specific surface areas and can rapidly exchange gas with the surrounding water, allowing oxygen to dissolve into the water quickly to increase the dissolved oxygen content of the water. The sufficient dissolved oxygen provides the necessary conditions for the catalytic oxidation of the manganese ore to the divalent manganese ions and iron ions. Meanwhile, the elastic pad 210 can protect the aeration ball 201.

[0044] Embodiment 2

[0045] Please refer to Figure 7 For the second embodiment of the present application, the vibration piece 3 is installed inside the aeration assembly 2 based on the previous embodiment.

[0046] Specifically, the vibration piece 3 includes a spherical shell 301 fixed inside the aeration ball 201. The spherical shell 301 has a vibration ball 310 installed inside. The lower surface of the vibration ball 310 is fixedly connected with a connecting rod 305. The outer surface of the connecting rod 305 is fixedly connected with a connecting block 304. The outer surface of the connecting block 304 is symmetrically connected with a pair of vibration rods 303. The spherical shell 301 has a connecting plate 302 fixedly connected inside. The connecting plate 302 is connected with the connecting rod 305 through a rotating shaft. One end of the vibration rod 303 is fixedly connected with a striking ball 306. The outer surface of the striking ball 306 is fixedly connected with a reset rod 307, which is in contact with the inner wall of the spherical shell 301. The outer surface of the reset rod 307 is sleeved with a reset spring 308. One end of the reset spring 308 is connected with the outer surface of the striking ball 306, and the other end is connected with the inner cavity of the spherical shell 301. The outer surface of the elastic pad 210 is fixedly connected with multiple vibration sheets 309. The vibration sheets 309 are made of elastic alloy material. The elastic alloy is a kind of metal material with high elasticity, fatigue resistance, corrosion resistance, and good mechanical strength. The vibration sheets 309 can be replaced with metal elastic sheets, titanium alloy, or shape memory alloy.

[0047] Referring to Figures 1-3 , the interior of the gabion 104 is filled with manganese ore, which refers to a mineral aggregate containing manganese elements and is an important raw material for extracting metallic manganese and preparing manganese compounds. The aeration assembly 2 is installed at the bottom of the manganese ore so that the bubbles generated at the bottom pass through the manganese ore layer from bottom to top, prolonging the residence time of the bubbles in the medium, improving the oxygen utilization rate, and reducing the compaction degree between manganese ore particles through the water flow generated by the aeration assembly 2, thereby avoiding bed clogging and maintaining a stable water flow channel. The gabion 104 is filled with manganese ore, and a mixed layer of original river sand and pebbles 1041 is laid on the side of the gabion 104 away from the main body 1 of the seepage collection corridor. A coarse sand layer is laid on the upper layer of the mixed layer of original river sand and pebbles 1041, and a fine sand layer is laid on the lower layer of the mixed layer of original river sand and pebbles 1041. The interior of the coarse sand layer and the fine sand layer is filled with manganese sand. The gabion 104 is laid on the mixed layer of original river sand and pebbles 1041, and a graded gravel layer 1042 is laid below the mixed layer of original river sand and pebbles 1041. The graded gravel layer 1042 includes an upper pebble layer and a lower ceramsite layer. A graded pebble layer 1043 is laid below the graded gravel layer 1042, and a filter geotextile 1044 is laid at the bottom of the graded pebble layer 1043.

[0048] On the basis of Embodiment 1, part of the gas enters the vibration member 3, blows the vibration ball 310, and drives the connecting rod 305 to swing left and right. When the connecting rod 305 swings, the connecting block 304 drives the two swing rods 303 to move, and the swing rods 303 indirectly drive the reset rod 307 to impact the spherical shell 301, thereby transmitting to the aeration ball 201 and making the aeration ball 201 swing within a certain amplitude. At the same time, the multiple vibration sheets 309 on the surface of the aeration ball 201 further intensify the swing of the aeration ball 201 due to their elasticity and inertia, thereby increasing the contact area and contact frequency between the groundwater and the manganese ore. When the connecting rod 305 moves, the reset spring 308 and the reset rod 307 are compressed or stretched to repeatedly vibrate the impact ball 306. The repeated vibration of the impact ball 306 indirectly and continuously impacts the spherical shell 301 through the reset rod 307, ensuring the continuous swing of the aeration ball 201 and maintaining the turbulent state of the water body. In turn, a large number of bubbles are continuously generated between the manganese ore and the groundwater, continuously strengthening the gas-liquid mass transfer and reaction process.

[0049] The water continues to flow down, through the pebble layer and the ceramsite layer in the graded gravel layer 1042, the pebble layer performs coarse filtration, intercepts medium-sized impurities, reduces the speed and impact force of the water flow, and reduces the burden of the subsequent filter layer, the ceramsite layer has a rich pore structure and a large specific surface area, and can adsorb organic matter, heavy metal ions, and nutrients such as nitrogen and phosphorus in the water through physical adsorption and ion exchange, and finally, the water passes through the graded pebble layer 1043 and the inverse filtration geotextile 1044, and further filtration, adsorption, and flocculation processes are performed, the graded pebble layer 1043 further filters the remaining small-particle impurities, and the inverse filtration geotextile 1044 prevents fine particles from passing through, and the charge characteristics and microstructure of the surface of the inverse filtration geotextile 1044 help to adsorb and flocculate colloidal substances in the water, thereby achieving the effect of purifying the water quality.

[0050] It is apparent to those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, regardless of what is stated in any section of the specification.

[0051] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
