Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a chemical wastewater treatment device and method. Background Art

[0002] In the process of chemical production, many chemical reactions will produce sulfur-containing wastewater. If the sulfur-containing wastewater is discharged directly into natural water bodies without treatment, it will cause water quality to deteriorate. Sulfide can reduce the oxygen content in the water, causing serious threats to the lives of aquatic organisms. At the same time, sulfur-containing wastewater can also cause the water quality to turn black and stink, breaking the ecological balance of the water body. Sulfur compounds themselves are toxic. If sulfur-containing wastewater is discharged into the water body, it will cause sulfur poisoning of some aquatic organisms and destroy the biological chain cycle in the water. If sulfur-containing wastewater is not used carefully for agricultural irrigation, it will cause the roots and stems of crops to rot, which will have an adverse effect on crop yields. Therefore, it is very important to treat sulfur-containing wastewater.

[0003] There are many ways to treat sulfur-containing wastewater. One of them is to treat it by adding iron powder. Before treating sulfur-containing wastewater, the pH value of the wastewater needs to be adjusted first. The appropriate pH value is conducive to the reaction between iron ions and sulfur ions and improves the precipitation effect. Usually, the pH value is adjusted to an appropriate range by adding alkaline substances (such as lime milk, sodium hydroxide, etc.), and iron salts are added to the sulfur-containing wastewater. The iron salts and the wastewater are fully mixed by stirring or aeration to ensure that the iron ions and sulfur ions are fully in contact and react. After a period of reaction, the iron sulfide precipitate is insoluble in water and will gradually form and settle to the bottom of the wastewater. At this time, the iron sulfide precipitate is removed from the wastewater and then discharged before the wastewater is discharged. During the process, the precipitate produced by the reaction is separated from the wastewater by filtration or adsorption. However, during the operation, whether it is the addition of sodium hydroxide powder or iron powder, most of them can only be placed on the shore of the treatment pool, and cannot be placed to a location far away from the shore of the treatment pool. The placement of powder treatment agents has limitations, which is not conducive to diffusion and slows down the reaction. At the same time, some powders form lumps due to improper storage. The agglomerated powders are mixed with normal powders and are easy to enter the treatment pool together during the placement process, which can easily cause insufficient reaction. At the same time, in the process of filtering the precipitates, filtering components such as filters are prone to blockage and need to be disassembled or cleaned frequently, which is very troublesome. Summary of the invention

The sleeve 131 and the connecting piece 132 are welded to each other. A long tube 1313 is bolted to the inner wall of the sleeve 131, and the top of the long tube 1313 is connected to the vertical cylinder 133. The two sides of the interior of the vertical cylinder 133 are rotatably connected to the first crushing roller 135 and the second crushing roller 136. The first crushing roller 135 and the second crushing roller 136 are rotatably connected.

The top of the inner cover 1311 is designed to be sharp to prevent powder from staying on the top of the inner cover 1311. A horizontal tube 139 is connected to one side of the inner cover 1311. The inner wall of the horizontal tube 139 is rotatably connected with a horizontal rod 1310. One end of the horizontal rod 1310 is connected to the transmission rod 137 through a bevel gear transmission. The vertical rod 1312 penetrates the inner cover 1311 and is rotatably connected to the penetration point. The other end is connected to the vertical rod 1312 through a gear transmission, and the transverse rod 1310 is connected to the first crushing roller 135 through a belt transmission. The surface of the vertical rod 1312 is bolted with a spiral blade 1314, and a fixing seat 1315 is also bolted below the surface of the long tube 1313. The fixing seat 1315 is partially fixed to the inner wall of the long tube 1313, leaving a gap for powder to pass through. The bottom end of the vertical rod 1312 is rotatably connected to the fixing seat 1315 to increase the rotational stability of the vertical rod 1312. The other side of the inner cover 1311 is fixed to the inner wall of the vertical cylinder 133 through a rod.

[0044] During operation, the delivery pipe 3 and the discharge pipe 4 are connected to a pump, and the wastewater enters the interior of the pool body 1 through the delivery pipe 3. At the same time, a notch is provided on the top of the shell 8, and the notch on the top of the shell 8 is located near the shore of the pool body 1. At this time, the vertical cylinder 133 stays below the notch. There are two vertical cylinders 133. The staff puts a certain amount of sodium hydroxide powder into one group of vertical cylinders 133 above the pool body 1. The fine powder can pass through the concentration bucket 134 and the first crushing roller 135 and the second crushing roller 136, enter the bottom of the vertical cylinder 133, and fall into the long tube 1313. The agglomerated powder falls between the first crushing roller 135 and the second crushing roller 136 and cannot pass through. Then the first motor 14 is turned on, and the output shaft of the first motor 14 drives the rotating column 10 to rotate through the belt, and then the rotating column 10 drives the sprocket 11 to rotate (the rotation direction of the rotating column 10 is counterclockwise, with Figure 4perspective as an example), let the chain 12 start to move, the chain 12 drives the sleeve 131 and the vertical cylinder 133 to start moving, the vertical cylinder 133 drives the transmission gear 138 to move, the transmission gear 138 moves along the surface of the tooth track 1317, and then the transmission gear 138 spins and drives the transmission rod 137 to rotate, the transmission rod 137 drives the transverse rod 1310 to rotate through the bevel gear, the transverse rod 1310 drives the first crushing roller 135 to rotate through the belt, and then the first crushing roller 135 rotates, and then the first crushing roller 135 drives the second crushing roller 136 to rotate through the gear, and the rotation directions of the first crushing roller 135 and the second crushing roller 136 are opposite, so that the agglomerated powder entering is broken up. , the broken powder enters the lower part of the vertical cylinder 133 to prevent the agglomerated powder material from participating in the reaction of the wastewater. At the same time, the horizontal rod 1310 drives the vertical rod 1312 to rotate through the bevel gear, and the vertical rod 1312 drives the spiral blade 1314 to rotate, pushing the sodium hydroxide powder downward in turn to achieve uniform material pushing. Then the vertical cylinder 133 moves together with the chain 12, continuously changing the position above the pool body 1. At the same time, the spiral blade 1314 pushes the material downward in turn, so that the powder treatment agent is evenly scattered at multiple different positions inside the pool body 1, which is conducive to the full reaction and improves the reaction efficiency. A stirring blade 1316 is also bolted to the bottom of the surface of the vertical rod 1312. When the vertical rod 1312 rotates During the process, the stirring blade 1316 can also be driven to rotate, and the stirring blade 1316 enters the shallow layer of wastewater. After the powder enters the wastewater, the stirring blade 1316 can also stir the wastewater around the area where the powder enters, further accelerating the diffusion efficiency of the powder treatment agent. The height of the stirring blade 1316 is higher than the height of the blade on the surface of the stirring rod 17. In this way, the stirring blade 1316 will not touch each other in the process of following the vertical cylinder 133 and the chain 12 to move. After the sodium hydroxide powder is added, wait for a certain period of time to adjust the pH value. A pH sensor needs to be installed inside the pool body 1 during actual use to realize online monitoring of the pH value. The pH value is adjusted between 8 and 10. In this range Within the range, added chemical reagents such as iron powder can effectively convert sulfide into insoluble substances, thereby achieving the removal of sulfide. At the same time, this pH value range is also helpful to maintain the stability of the wastewater and the smooth progress of subsequent treatment; then iron powder is added to the inside of another vertical cylinder 133, and the iron ions and sulfur ions are fully in contact and react to generate iron sulfide precipitates, thereby achieving the effect of desulfurization of the wastewater; two vertical cylinders 133 are arranged inside a group of shells 8, one for sodium hydroxide powder and the other for iron powder, to prevent the residues from interfering with each other. If other powdered treatment agents need to be added, several vertical cylinders 133 can be arranged to avoid interference between the powdered treatment agents.

[0046] After the desulfurization reaction is completed, a large amount of precipitation is generated inside the pool body 1. The solenoid valve 7 is opened to put the vertical pipe 6 in a state of passage, and then the wastewater is discharged through the vertical pipe 6. The surface of the bracket 5 is also bolted with a transverse frame 21, and the top of the transverse frame 21 is bolted with a linear reciprocating motor 22. The output shaft of the linear reciprocating motor 22 is fixed with a striker 24, which is spherical and made of rubber. All the linear reciprocating motors 22 are started synchronously, and drive the striker 24 to reciprocate up and down, knocking on the top of the pool body 1, and the vibration generated is transmitted to the inside of the pool body 1, so that the pool body 1 The sediment at the bottom is resuspended and discharged together with the wastewater, and the height at the center of the bottom of the inner wall of the pool body 1 is the lowest, which makes it easy for the wastewater and sediment to flow to the vertical pipe 6, making it easier to discharge the sediment in the pool; then the sediment and the treated wastewater pass through the vertical pipe 6 and fall onto the surface of the fine mesh 187, the wastewater passes through the fine mesh 187, and the sediment can be intercepted by the fine mesh 187, the second motor 15 is turned on to drive the transmission column 184 to rotate, and then the transmission column 184 drives the vertical column 185 to rotate through the bevel gear, the vertical column 185 drives the ring 186 to rotate, and makes the fine mesh 187 do a circular motion.
