Description

TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of wastewater treatment, in particular to a wastewater treatment equipment and method. BACKGROUND

[0002] Wastewater treatment is a scientific management and effective governance of wastewater to reduce or eliminate the negative impact of wastewater on the environment. The method of wastewater treatment is roughly divided into physical treatment method, chemical treatment method and biological treatment method. The physical treatment method mainly separates and removes insoluble pollutants in wastewater such as oil film, oil bead, etc. by physical action. Centrifugal separation method and screen filtration interception method are two common physical treatment methods. The chemical treatment method mainly separates and removes the pollutants in the wastewater in the form of dissolution, colloid or transforms them into harmless substances by chemical reaction and mass transfer. The biological treatment method is to use the life activity process of microorganisms to transform the organic matter in the wastewater, so as to achieve the method of purifying and treating wastewater. Different treatment methods can be applied in different wastewater treatment processes to improve the wastewater treatment effect.

[0003] Stone coal is a kind of low-grade multi-metallic symbiotic ore with low carbon content and low calorific value, and also a very important vanadium ore resource. It is widely used, such as being used as a raw material in the upstream of the vanadium redox flow battery industry chain. In addition, the total reserves of stone coal vanadium are 6 to 7 times of the total reserves of vanadium in vanadium-titanium magnetite. Therefore, the production of vanadium products from stone coal has a good development prospect. At present, the stone coal vanadium extraction process can be summarized as two representative types: roasting vanadium extraction process (fire method vanadium extraction process) and wet vanadium extraction process. In the wet acid leaching stone coal vanadium extraction process, acid is used to leach vanadium in the form of VO2+ (vanadium oxy radical ion) from the vanadium-containing solid waste. After enrichment treatment, the pH value of the vanadium-containing liquid is 2 to 3, and it still contains high concentrations of impurities such as iron, aluminum, manganese and phosphorus.

[0004] In the process of wet acid leaching stone coal vanadium extraction, wastewater treatment equipment is usually used to filter and purify the wastewater generated in the preparation of vanadium extraction process. However, the traditional wastewater treatment equipment has some shortcomings. When the traditional wastewater treatment equipment treats the wastewater generated in the wet acid leaching stone coal vanadium extraction process, only a single PH value adjusting agent is added to the wastewater, and then a detection probe is used to detect the PH value of the water. The detection depth of the detection probe is limited, and the mixed uniformity of the agent is poor, and the PH value of the wastewater at the lower part is not up to standard. In order to make the PH value adjustment meet the requirements, an excessive amount of agent is often added, which wastes a lot of materials and reduces the wastewater treatment efficiency. SUMMARY

[0049] Embodiment one

[0050] Reference Figures 1-5 As shown, the wastewater treatment device provided by the embodiment mainly comprises a stirring part 100 and a detection part 200, wherein the stirring part 100 comprises a stirring container 101, the stirring container 101 is provided with a dosing opening 102, a first liquid inlet 103 and a first liquid outlet 104, and a stirring paddle 105 is arranged in the stirring container 101. The detection part 200 comprises a detection container 201, the detection container 201 is provided with a second liquid inlet 202 and a discharge opening 203, the second liquid inlet 202 is connected to the first liquid outlet 103 of the stirring container 101 through a hose 204, and a detection probe 205 is arranged in the detection container 201. In addition, the detection container 201 is connected to a driving device 206, and the driving device 206 drives the detection container 201 to move back and forth.

[0051] The device of the embodiment is provided with the stirring part 100, after the wastewater to be treated enters the stirring container 101, the wastewater can be fully mixed with the reagent added from the dosing opening 102 under the stirring action of the stirring paddle 105, the wastewater treatment effect is better, and there is no case of excessive reagent input. The reagent and the wastewater to be treated are more uniformly mixed, which is also beneficial to improve the efficiency of wastewater treatment. In addition, the device of the embodiment is also provided with the detection part 200 capable of moving back and forth, when the treated wastewater is detected, the treated wastewater can be fully contacted with the detection probe 205 in the detection container 201, and the treated wastewater at a specific point is not detected, so that the detection result is more accurate.

[0052] In the process of extracting vanadium from stone coal by wet acid leaching, if the traditional wastewater treatment method is used, the PH value adjusting agent is added into the wastewater alone, and then the PH value of the water is detected by the detection probe 205. The amount of the agent added is excessive and the accuracy of the detection result is low. If the wastewater treatment equipment provided in the embodiment is used, the wastewater generated in the process of extracting vanadium from stone coal by wet acid leaching is discharged into the stirring container 101 through the first liquid inlet 103, and the PH value adjusting agent can be added into the stirring container 101 through the dosing port 102. Then, the stirring paddle 105 can fully stir the mixture of the agent and the wastewater, the agent is uniformly mixed with the wastewater, and the PH value of the wastewater is adjusted. When the above-mentioned fully reacted mixture is discharged into the detection container 201, the detection container 201 moves back and forth under the drive of the driving device 206, and the liquid in the detection container 201 is constantly stirred, so that the mixture in the detection container 201 can fully contact with the detection probe 205. The detection probe 205 can only detect a certain area, so that the detected PH value can reflect the condition of the whole mixture, the accuracy of the detection is improved, and the PH value of the treated mixture can be more objectively known.

[0053] In the embodiment, the dosing pipe extending to the outside can be arranged at the dosing port 102, and the PH value adjusting agent is conveyed through the dosing pipe.

[0054] In an example, the driving device 206 includes a first movable block 2061 fixed below the detection container 201, the first movable block 2061 is arranged in the first sliding groove 2062, and the first movable block 2061 is connected to the nut of the first lead screw 2063, and the first lead screw 2063 is connected to the first driving motor 2064.

[0055] The screw rod transmission takes the screw rod as the main rotating part, and the linear motion of the secondary rotating part such as the nut is generated by the rotation of the screw rod, so as to realize the motion transmission of the mechanical element. The principle is based on stable sliding friction or rolling friction, and the rotation is converted into linear motion. The nut is the secondary rotating part in the screw rod transmission, and has a thread structure matched with the screw rod inside. When the screw rod rotates, the nut moves along the axis of the screw rod or rotates, so as to realize linear or rotary motion. Therefore, in the embodiment, the first movable block 2061 is connected to the nut of the first lead screw 2063, and when the first lead screw 2063 rotates, the nut on the first lead screw 2063 moves linearly, and then the first movable block 2061 fixed on the nut can move linearly. At the same time, since the first movable block 2061 is fixedly connected with the detection container 201, the final effect is that the detection container 201 can move back and forth in the linear direction, so that the mixture in the detection container 201 can fully contact with the detection probe 205, and the detection accuracy of the mixture is improved.

[0056] In some implementations, the first screw rod 2063 can also not be provided with a nut, and in this case, the first screw rod 2063 is provided with a thread matched with the first movable block 2061 inside the first movable block 2061, and the first screw rod 2063 directly drives the first movable block 2061 to move linearly when the first screw rod 2063 rotates. It can be seen that this implementation simplifies the nut and the first movable block 2061, which is equivalent to integrating the function of the nut into the first movable block 2061, or from another perspective, it is equivalent to the nut replacing the position of the first movable block 2061.

[0057] In an example, one end of the stirring paddle 105 is connected with the first direction shaft 106, the first direction shaft 106 is provided with the first belt pulley 107, one end of the first screw rod 2063 is connected with the second direction shaft 209, the second direction shaft 209 is provided with the second belt pulley 210, and the other end of the second direction shaft 209 is connected with the first driving motor 2064. The first belt pulley 107 and the second belt pulley 210 are connected by the same belt 211.

[0058] Reference Figure 3 When the first motor 2064 works, on the one hand, the first screw rod 2063 rotates through the transmission action of the second direction shaft 209, and in turn drives the first movable block 2061 on the first screw rod 2063 to move; on the other hand, the first belt pulley 107 and the second belt pulley 210 are connected by the same belt 211, so that the first direction shaft 106 also rotates under the action of the first driving motor 2064 at the same time as the second direction shaft 209 rotates, thereby driving the stirring paddle 105 to rotate. It can be seen that in this embodiment, the rotation of the stirring paddle 105 and the rotation of the first screw rod 2063 (i.e., detecting the back-and-forth movement of the container 201) are no longer provided with separate driving devices, and their movements can be achieved by the same driving motor. Not only does this reduce the number of components invested, but also the rotation of the stirring paddle 105 and the back-and-forth movement of the container 201 have the same frequency, which enhances the collaborative function of the entire wastewater treatment equipment.

[0059] In an example, the stirring part 100 and the detection part 200 are placed in the same outer shell 500, and the left and right ends of the detection container 201 are respectively connected to the outer shell 500 through the first spring 207.

[0060] Reference Figure 2 or Figure 3As shown in the figure, not only the stirring part 100 and the detection part 200 are placed in the same outer shell 500, but also, as can be seen from the figure, part of the stirring part 100 (such as the upper surface and the two side surfaces) has been shared with the outer shell 500 or said stirring container 101 utilizes the outer shell 500, strengthening their integration. The detection part 200 needs to move back and forth, so it is only placed in the outer shell 500. Even so, in order to fully realize the integration of the outer shell 500 and the detection container 201, a first sliding groove 2062 can be provided on the outer shell 500.

[0061] The left and right ends of the detection container 201 are respectively connected to the outer shell 500 through first springs 207. The detection container 201 pulls and presses the first springs 207 from both sides during sliding, and the first springs 207 elastically deform to buffer the pressing and pulling force, ensuring the stability of the detection container 201 during movement.

[0062] In an example, a base 600 is fixed below the outer shell 500, which increases the contact area between the entire processing device and the ground, providing better stability.

[0063] In an example, a first filter plate 208 is further provided in the detection container 201. The device of the present embodiment filters the impurities in the mixed liquid before detecting the mixed liquid after stirring, improves the cleanliness of the water after wastewater treatment, and improves the accuracy of the detection result.

[0064] In an example, the wastewater treatment device of the present embodiment further comprises a filtering part 300, and the filtering part 300 comprises a filtering container 301. The filtering container 301 has a third liquid inlet 302, a second liquid outlet 303, and a sewage outlet 304. The second liquid outlet 303 of the filtering container 301 is connected to the first liquid inlet 103 of the stirring container 101, and the filtering container 301 is provided with a second filter plate 305.

[0065] Reference Figure 2 As shown, the device of the present embodiment is provided with a filtering part 300. The impurities in the wastewater are filtered before the wastewater is mixed with the reagent, that is, the impurities in the wastewater are intercepted and filtered, the cleanliness of the water is improved, and the accuracy of the subsequent detection result is improved.

[0066] In an example, a filter screen 306 is further provided inside the filtering container 301, and the filter screen 306 is located above the second filter plate 305.

[0067] In the embodiment, the filter screen 306 is generally used to filter the impurities with large particle size in the wastewater, and the material and structure of the filter screen 306 enable the filter screen 306 to intercept and remove the impurities such as solid particles, suspended matters and microorganisms in the wastewater. The second filter plate 305 is generally used to filter the impurities with small particle size in the wastewater. The filtering part 300 has the filter screen 306 and the second filter plate 305, and the impurities with large particle size are filtered first, and then the impurities with small particle size are filtered. Through the cooperation of the filter screen 306 and the second filter plate 305, the filter screen 306 and the second filter plate 305 intercept and filter the impurities in the wastewater in batches, thereby improving the cleanliness of the water.

[0068] In an example, the filtering container 301 has mounting frames 307 on both sides, and the filter screen 306 is arranged on the mounting frames 307 on both sides, respectively. Further, the filtering container 301 is further provided with positioning plates 308 on both sides, and the second springs 309 are fixed on the positioning plates 308, and the upper ends of the second springs 309 are connected to the filter screen 306.

[0069] Reference Figure 4 As shown in the embodiment, the filter screen 306 is arranged on the mounting frames 307 on both sides, respectively, and the filter screen 306 is fixed by the mounting frames 307. During the working process of the filter screen 307, the filter screen 307 will be deformed or displaced due to the impact of the wastewater. In the embodiment, the positioning plates 308 and the second springs 309 are arranged to offset or eliminate the adverse effects of the deformation or displacement caused by the impact of the wastewater, so as to ensure the working state and efficiency of the filter screen 307.

[0070] In an example, the filter screen 307 is further provided with a stop ring 310 at each end, respectively, so as to avoid the filter screen 307 from falling into the filtering container 301 when the filter screen 307 is deformed or displaced too much due to the excessive impact of the wastewater.

[0071] In an example, the filtering container 301 is fixed above the stirring container 101 by the support rods 700, so that the wastewater filtered by the filtering part 300 can be directly discharged into the stirring container 101, thereby shortening the flow distance of the wastewater and enhancing the compactness of the wastewater treatment equipment of the embodiment and reducing the occupied space of the equipment. For example, four support rods 700 are fixed below the filtering container 301, and the support rods 700 can be installed at the four corners of the bottom end of the filtering container 301. The bottom ends of the four support rods 700 are fixedly connected to the four corners of the stirring container 101, and the wastewater filtered in the filtering container 301 is discharged into the stirring container 101 through the discharge pipeline.

[0072] In an example, the wastewater treatment device further comprises a material injection part 400 fixed above the filter container 301 through a support assembly 401, the support assembly 401 is connected with a top plate 402, and a spray plate 403 is arranged below the top plate 402. One side of the spray plate 403 is connected with a wastewater injection hose extending to the outside.

[0073] In an example, the spray plate 403 is connected to a second movable block 404 arranged in a second sliding groove 405 at the top plate 402, and the second movable block 404 is connected to a nut of a second lead screw 406, one end of the second lead screw 406 is connected to a second driving motor 407.

[0074] Referring to Figure 5 Based on the structure, when the second driving motor 407 is started, the second lead screw 406 is driven to rotate, and then the second movable block 404 can move back and forth along the second sliding groove 405, and the spray plate 403 fixed on the second movable block 404 also moves back and forth along the second sliding groove 405. When the spray plate 403 sprays wastewater, the wastewater can be uniformly sprayed onto the filter screen 306 or the second filter plate 305 of the filter container 301. At this time, it can be understood that the width of the third liquid inlet 302 on the filter container 301 should be adapted to the longest distance of the back-and-forth movement of the spray plate 403, so that the wastewater can be smoothly sprayed into the filter container 301.

[0075] In some implementations, the second lead screw 406 can also not be provided with a nut, at this time, the second movable block 404 has a thread matched with the second lead screw 406, and the second lead screw 406 directly drives the second movable block 404 to move linearly when rotating. It can be seen that this implementation simplifies the nut and the second movable block 404, which is equivalent to integrating the function of the nut into the second movable block 404, or from another angle, it is equivalent to that the nut replaces the position of the second movable block 404.

[0076] In an example, the support assembly 401 comprises a horizontal plate 4011 and a vertical plate 4012, the horizontal plate 4011 is fixed on the side of the filter container 301, the vertical plate 4012 is fixed on the horizontal plate 4011, and the support assembly 401 is connected with the top plate 402, and two ends of the top plate 402 are fixed on the vertical plates 4012 on both sides.

[0077] The wastewater treatment equipment provided in this embodiment includes a stirring part 100 and a detection part 200. The stirring part 100 includes a stirring container 101, the stirring container 101 has a dosing port 102, a first liquid inlet 103 and a first liquid outlet 104, and a stirring paddle 105 is provided inside the stirring container 101; the detection part 200 includes a detection container 201, the detection container 201 has a second liquid inlet 202 and a discharge port 203, and the second liquid inlet 202 is connected to the stirring container 101 through a hose 204. The first liquid outlet 104 is provided, and a detection probe 205 is provided inside the detection container 201. The detection container 201 is connected to a driving device 206. The driving device 206 enables the detection container to move back and forth. Therefore, after the reagent and the wastewater are mixed, the stirring paddle 105 stirs the mixture of the reagent and the wastewater to mix them evenly, thereby making the wastewater treatment efficiency higher and saving the amount of reagent input. In addition, during the detection, since the detection container 201 can move back and forth, it will not only detect the treated wastewater at a specific point, and the detection result is more accurate.

[0078] Example 2

[0079] Figure 6 This is a schematic diagram of a wastewater treatment method according to an embodiment of the present invention. Figure 6 As shown, method 600 can use the wastewater treatment equipment shown in Example 1 to treat wastewater, which includes: S610, adding the agent for treating wastewater into the stirring container through the dosing port, and discharging the wastewater to be treated into the stirring container through the first liquid inlet; S620, stirring the mixture of the agent and the wastewater to be treated by a stirring paddle; S630, discharging the stirred mixture into the detection container through a hose, and the detection probe completes the detection of the stirred mixture during the back-and-forth movement of the detection container; S640, discharging the detected mixture to the outside through the discharge port.

[0080] For example, the treatment method of this embodiment is used to treat the wastewater in the process of wet acid leaching of stone coal for vanadium extraction. The wastewater generated by wet acid leaching of stone coal for vanadium extraction is discharged into the stirring container 101 through the first liquid inlet 103, and the agent for adjusting the pH value can be added to the stirring container 101 through the dosing port 102. After that, the stirring paddle 105 can fully stir the mixture of the agent and the wastewater, so that the agent and the wastewater are mixed evenly, which is conducive to adjusting the pH value of the wastewater. After the above-mentioned fully reacted mixed liquid is discharged into the detection container 201, the detection container 201 moves back and forth under the drive of the driving device 206, thereby driving the liquid in the detection container 201 to be continuously stirred, so that the mixed liquid in the detection container 201 can fully contact with the detection probe 205, avoiding the detection probe 205 only detecting a specific area, so that the detected pH value can reflect the situation of the entire mixed liquid, improving the accuracy of the detection, and more objectively knowing the pH value of the treated mixed liquid.

[0081] Further, before detecting the mixed liquid after stirring, the impurities in the mixed liquid can also be intercepted and filtered to improve the cleanliness of the water and improve the accuracy of the detection results. For example, a first filter plate 208 is arranged in the detection container 201, and the first filter plate 208 is used to intercept and filter the impurities in the mixed liquid, and then the filtered mixed liquid is detected.

[0082] Further, before the wastewater and the medicament are mixed and stirred, the wastewater can also be pre-filtered to improve the cleanliness of the wastewater and improve the accuracy of the subsequent detection results. For example, the treatment equipment adopted includes a filtering part 300, and a second filter plate 305 is arranged in the filtering container 301 of the filtering part 300, so that the wastewater can be pre-filtered by the second filter plate 305. The wastewater can also be pre-filtered by using the double filtering effect of the second filter plate 305 and the filter screen 306.

[0083] In the wastewater treatment method of the embodiment, the wastewater can be sprayed back and forth by the spray plate 403, so that the wastewater is more uniformly sprayed onto the filter screen 306 or the second filter plate 305 of the filtering container 301, thereby improving the pre-filtering effect of the wastewater.

[0084] The wastewater treatment method provided in the embodiment can uniformly mix the medicament and the wastewater to be treated by stirring the mixed liquid of the medicament and the wastewater to be treated by the stirring paddle after the medicament is mixed with the wastewater, so that the wastewater treatment efficiency is higher and the input amount of the medicament is saved. During detection, the detection probe completes the detection of the mixed liquid after stirring during the back-and-forth movement in the detection container, so that the treated wastewater in a specific point or region is not detected, and the detection result is more accurate.
