Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a device and method for treating water polluted by heavy metal complexes. Background Art

[0002] Water bodies contaminated by heavy metal complexes refer to water containing heavy metal ions that form stable complexes with organic or inorganic ligands. This form of heavy metal pollutants is more difficult to remove than metal ions that exist alone because they usually have higher solubility and stability and are not easily removed by conventional methods such as precipitation and filtration.

[0003] Existing technologies for treating water bodies contaminated by heavy metal complexes usually include the steps of pretreatment, complex breaking, heavy metal removal, and post-treatment. The contaminated water body is first subjected to preliminary filtration and acid-base adjustment, and then the pretreated contaminated water body is subjected to complex breaking treatment with chemical reagents. The heavy metals are then precipitated in the form of insoluble salts by chemical precipitation, and free heavy metal ions are captured by high-efficiency adsorbents such as activated carbon, thereby achieving the function of treating the contaminated water body. However, when the precipitated contaminated water body contacts the high-efficiency adsorbent, the contaminated water body needs to be extracted. The water inlet of the extraction equipment used needs to be adjusted according to the sedimentation height of the contaminated water body, and the water inlet of the extraction equipment is always located at the upper end of the sediment. Some sediments will be re-suspended by the flow of the contaminated water body, and the re-suspended sediments will be extracted together with the contaminated water body.

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0038] See also Figure 1-Figure 4 A heavy metal complex contaminated water treatment device comprises a sedimentation frame 1, wherein a suction device 2 is arranged in the sedimentation frame 1.

[0039] See also Figure 1 and Figure 2 The heavy metal complex contaminated water treatment equipment also includes a complex breaking device 3, which is connected to the sedimentation frame 1. The complex breaking device 3 includes a positioning ring 31 that is detachably mounted on the upper end of the sedimentation frame 1 through two support frames.

[0040] During specific work, the support column at the lower end of the sedimentation frame 1 is fixed in the working position before processing, so as to limit the sedimentation frame 1. Then the positioning ring 31 is placed above the sedimentation frame 1 through two support frames, and then the two support frames are fixedly connected to the sedimentation frame 1 through bolts to realize the function of limiting the positioning ring 31. The positioning ring 31 fixes multiple processing barrels 32 above the sedimentation frame 1, and the downpipe at the lower end of the processing barrel 32 is equipped with a valve and the valve is in a closed state.

[0041] See also Figure 2 , Figure 7 and Fig.10 A clamping mechanism 33 is connected to the upper end of the processing barrel 32, and the clamping mechanism 33 includes two clamping frames 331 symmetrically installed on the outer surface of the processing barrel 32 near the upper end. A support plate 332 is inserted in the clamping frame 331, and a limiting plate 333 is inserted on the support plate 332 located inside the clamping frame 331. The limiting plate 333 is plugged into and matched with the clamping frame 331, and a circular plate 334 is commonly installed on the upper ends of the two support plates 332.

[0042] During specific operation, after multiple processing barrels 32 are positioned, multiple circular plates 334 are moved to the top of the corresponding processing barrels 32 in turn, and the circular plates 334 are pressed downward. The circular plates 334 are inserted into the corresponding two clamping frames 331 through two support plates 332, and then the corresponding two limiting plates 333 are inserted into the corresponding clamping frames 331 and support plates 332, thereby realizing the function of limiting the circular plates 334, and then the pretreated polluted water is poured into the multiple processing barrels 32, and then the complex breaking chemical reagents are poured into the multiple processing barrels 32.

[0043] See also Figure 1 , Figure 6 and Figure 8 A driving mechanism 36 is commonly connected between the multiple processing barrels 32, and the driving mechanism 36 includes a driving motor 361 fixedly connected to the multiple processing barrels 32 through a base. A transmission rod 362 is installed on the output shaft of the driving motor 361, and a driving gear 363 is installed on the upper end of the transmission rod 362.

[0044] During specific operation, the driving motor 361 is fixed above the sedimentation frame 1 while multiple processing barrels 32 are positioned, and then the driving motor 361 is connected to the existing power supply. After the polluted water and chemical reagents are poured into the multiple processing barrels 32, the driving motor 361 is started, and the driving motor 361 drives the transmission rod 362 to rotate, and the transmission rod 362 drives the driving gear 363 to rotate.

[0045] See also Figure 1 , Figure 2 , Figure 6 , Figure 8 and Fig.10The clamping mechanism 33 is connected to a lifting mechanism 34, and the lifting mechanism 34 includes a rotating tube 341 that penetrates the middle of the circular plate 334 and is rotatably connected thereto, a rectangular bar 342 is slidably penetrated and connected to the middle of the rotating tube 341, a sliding sleeve 343 is slidably connected to the upper end of the rectangular bar 342, and a limiting frame 344 with a U-shaped structure and an opening facing downward is rotatably connected to the outer surface of the sliding sleeve 343, the lower end of the limiting frame 344 is fixedly connected to the upper end of the circular plate 334, and a driven gear 345 is installed on the upper end of the sliding sleeve 343, and the driving gear 363 is meshed with multiple driven gears 345 at the same time.

[0046] See also Figure 1 and Fig.10 The lifting mechanism 34 also includes a rotating circular plate 346 mounted on the rectangular bar 342, and a lifting column 347 is symmetrically installed at the lower end of the rotating circular plate 346. A semi-spherical protrusion is integrally formed at the lower end of the lifting column 347. A plurality of arc-shaped protrusions 348 are arranged below the rotating circular plate 346 and are evenly distributed in the circumference and fixedly connected to the upper end of the circular plate 334.

[0047] During specific operation, while the circular plate 334 is fixed above the treatment barrel 32, the circular plate 334 drives the lifting mechanism 34 to be located above the treatment barrel 32. After the polluted water and chemical reagents are poured into multiple treatment barrels 32 and the driving motor 361 is started, the rotating active gear 363 simultaneously drives multiple driven gears 345 to rotate. The driven gear 345 drives the rectangular bar 342 to rotate through the sliding sleeve 343. The rectangular bar 342 rotates in the middle of the circular plate 334 through the rotating tube 341. At the same time, the rectangular bar 342 drives the rotating circular plate 346 to rotate. The rotating circular plate 346 drives two lifting columns 347 to rotate. During the rotation of the lifting column 347, it continuously contacts with multiple arc-shaped protrusions 348. The arc-shaped protrusions 348 guide the lifting column 347, so that the lifting column 347 moves up and down. The lifting column 347 moving up and down drives the rectangular bar 342 to move up and down through the rotating circular plate 346.

[0048] See also Figure 1 and Figure 6 The lifting mechanism 34 is connected to a stirring mechanism 35 located inside the processing barrel 32, and the stirring mechanism 35 includes a stirring rod 351 installed at the lower end of the rectangular bar 342, and a plurality of leak plates 352 evenly distributed from top to bottom are installed on the surface of the stirring rod 351, and a plurality of stirring blades 353 evenly distributed circumferentially are installed on the annular side wall of the leak plate 352.

[0049] During specific operation, while the circular plate 334 is fixed, the stirring mechanism 35 is limited inside the treatment barrel 32 by the rectangular bar 342. When the polluted water is treated, the rectangular bar 342 that moves up and down and rotates drives multiple leaking plates 352 to move up and down and rotate through the stirring rod 351. The leaking plates 352 that move up and down stir the polluted water up and down through the leakage holes. At the same time, the leaking plates 352 drive multiple stirring blades 353 to rotate, and the stirring blades 353 stir the polluted water to ensure that the polluted water reacts completely with the chemical reagent, thereby improving the effect of breaking the complex of the polluted water. At the same time, the polluted water is treated in multiple treatment barrels 32, realizing small-scale and multiple breaking complex treatments, further improving the effect of breaking the complex of the polluted water.

[0050] After the decomposition reaction of the polluted water in the treatment barrel 32 is completed, the valve on the downpipe is opened, and the polluted water falls into the sedimentation frame 1 through the downpipe. Then, flocculants are added into the sedimentation frame 1 to precipitate the polluted water.

[0051] See also Figure 1 , Figure 6 , Figure 8 and Fig. 9 The suction device 2 includes a positioning bar 21 installed on the inner wall of the sedimentation frame 1 and in a horizontal state. A lifting pipe 22 is slidably connected to the positioning bar 21. The lower end of the lifting pipe 22 is provided with a trumpet-shaped opening and a filter plate is installed. The outer surface of the lifting pipe 22 is connected to a suspension mechanism 23. A flexible hose 24 is installed on the upper end of the lifting pipe 22. The end of the flexible hose 24 away from the lifting pipe 22 is connected to a drainage mechanism 25.

[0052] See also Figure 6 , Figure 8 and Fig. 9 The suspension mechanism 23 includes two fixing rods 231 symmetrically installed on the outer surface of the lifting tube 22 near the lower end, and a fixing ring 232 sleeved on the outer periphery of the lifting tube 22 is installed on the two fixing rods 231, and a suspension module 233 is installed on the outer ring surface of the fixing ring 232.

[0053] See also Figure 6 , Figure 8 and Fig. 9 The drainage mechanism 25 includes an L-shaped frame 251 installed on the outer wall of the sedimentation frame 1, and a drainage pipe 252 is installed on the vertical section of the L-shaped frame 251. The drainage pipe 252 is fixedly connected and communicated with the flexible hose 24. A water pump 253 is installed on the drainage pipe 252, and the water pump 253 is fixedly connected to the upper end of the vertical section of the L-shaped frame 251.

[0054] During specific operation, the water pump 253 is connected to the existing power supply before treatment, and the suspension module 233 is an existing foam, air bag, etc. When the polluted water is poured into the sedimentation frame 1, the polluted water exerts buoyancy on the suspension module 233, and the suspension module 233 is forced to drive the lifting pipe 22 to rise vertically as the liquid level of the polluted water rises through the fixing ring 232 and the fixing rod 231. The trumpet-shaped opening at the lower end of the lifting pipe 22 exceeds the lowest position of the suspension module 233, ensuring that the water inlet of the trumpet-shaped opening is located below the liquid level of the polluted water. When flocculant is added to the polluted water and precipitated for a period of time, the water pump 253 is started, and the water pump 253 absorbs the precipitated polluted water through the flexible hose 24 and the lifting pipe 22. As the liquid level of the polluted water drops, the suspension module 2 33 drives the lifting pipe 22 to gradually descend until the polluted water after the sedimentation is completely absorbed. During this process, there is no need to pay attention to the amount of sediment, and there is no need to adjust the position of the water inlet of the lifting pipe 22. The lifting pipe 22 can gradually descend with the liquid level to ensure that the polluted water after the sedimentation is completely absorbed. The lifting pipe 22 absorbs from top to bottom, which can reduce the intensity of the flow of polluted water close to the sediment, reduce the degree of disturbance of the polluted water on the upper end of the sediment, and thus reduce the amount of sediment re-suspension, effectively reducing the amount of sediment carried by the polluted water into the water pump 253 and the drain pipe 252 through the lifting pipe 22, thereby reducing the possibility of blockage of the treatment equipment due to the accumulation of absorbed sediment, and ensuring the normal operation of the treatment equipment.

[0055] See also Figure 1 , Figure 6 and Fig.11 The heavy metal complex contaminated water treatment equipment also includes an adsorption device 4, which is arranged on one side of the precipitation frame 1. The adsorption device 4 includes a cylindrical barrel 41 arranged on one side of the precipitation frame 1, and a spiral tube 42 is installed at the bottom of the cylindrical barrel 41, and an adsorption carrier 43 is installed in the spiral tube 42.

[0056] See also Figure 2 , Figure 5 and Fig.11 The lower end of the spiral tube 42 passes through the bottom wall of the cylindrical barrel 41 and is installed with a filter screen 421. The upper end of the spiral tube 42 is integrally formed with a conical opening, and the conical opening is located below the water outlet of the drain pipe 252. A baffle screen 422 is inserted into the upper end of the spiral tube 42.

[0057] During specific work, the adsorption carrier 43 is a microplastic carrier. Before treatment, the baffle net 422 and the spiral tube 42 are in a separated state. A large amount of adsorption carrier 43 is poured into the spiral tube 42 from the upper end of the spiral tube 42, and then the baffle net 422 is inserted into the spiral tube 42. Then the cylindrical barrel 41 is fixed to the working position on one side of the sedimentation frame 1 through its own support column. The cylindrical barrel 41 drives the upper end of the spiral tube 42 to be located directly below the outlet of the drain pipe 252. During treatment, the polluted water extracted by the water pump 253 is discharged through the outlet of the drain pipe 252 and enters the spiral tube 42 through the upper end of the spiral tube 42. The polluted water contacts with a large amount of adsorption carriers 43, and the adsorption carriers 43 adsorb and remove the heavy metal ions remaining in the polluted water. The spiral tube 42 can effectively prolong the contact time between the polluted water and the adsorption carrier 43, further enhancing the effect of removing heavy metal ions in the polluted water. After passing through the spiral tube 42, the polluted water is discharged from the filter net 421, and the existing collection bucket collects the treated polluted water.

[0058] Repeat this step until all the polluted water to be treated is treated, connect the existing pump body to the lower end of the spiral tube 42, and the pump body injects cleaning water into the spiral tube 42 to achieve the function of backwashing the adsorption carrier 43 and restore the adsorption function of the adsorption carrier 43. The backwashing water flows out through the upper end of the spiral tube 42 and falls into the cylindrical barrel 41. After the adsorption carrier 43 is backwashed, the water in the cylindrical barrel 41 is discharged and the treatment is completed.

[0059] In addition, the present invention also provides a method for treating heavy metal complex contaminated water, which specifically includes the following steps: S1: initially pouring the pretreated heavy metal complex contaminated water into multiple treatment barrels 32 respectively, and then pouring the complex breaking chemical reagents into the multiple treatment barrels 32.

[0060] S2: starting the driving mechanism 36, which drives the stirring mechanism 35 to stir the polluted water body through the lifting mechanism 34, and the chemical reagent breaks the complex of the heavy metal complex polluted water body.

[0061] S3: After the complex breaking treatment, the polluted water falls into the sedimentation frame 1, and then a flocculant is added to precipitate the polluted water.

[0062] S4: After the polluted water is precipitated, the drainage mechanism 25 is started, and the drainage mechanism 25 absorbs the precipitated polluted water through the flexible hose 24 and the lifting pipe 22.

[0063] S5: The sucked sewage enters the spiral tube 42, and the adsorption carrier 43 in the spiral tube 42 removes the heavy metal ions remaining in the polluted water. The treated polluted water falls into an existing collection bucket outside, and the treatment of the polluted water is completed.
