Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment and recycling device. Background Technology
[0002] With the development of modern society, the amount of heavy metal ions in industrial wastewater is increasing. Since heavy metal ions are difficult to degrade under natural conditions, they not only pollute water sources and soil, but also eventually enter the human body through bioaccumulation in the food chain, thus harming human health. Therefore, the treatment of wastewater containing heavy metal ions is particularly important.
[0003] Existing wastewater treatment and recycling devices suffer from ineffective filtration and long processing times. Wastewater typically contains fixed impurities, which slow down the machine and increase processing time. These solids also add screening steps and can even damage the machine, leading to economic losses and extended working hours. Furthermore, existing wastewater treatment and recycling systems often retain bacteria after recycling, and some substances may pose health risks to humans and animals if consumed. The wastewater may even be unsuitable for agricultural irrigation, only suitable for industrial use. The lack of thorough disinfection further complicates the process, wasting time and resources and reducing efficiency. Therefore, a new wastewater treatment and recycling device is needed to address these issues. Utility Model Content

[0017] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Example 1 refer to Figures 1 to 3Embodiment 1 describes a device including a base 1 located at the bottom of the entire device. A support block 2 is fixedly installed on the upper end of the base 1, and a first movable frame 3 and a second movable frame 4 are respectively installed on the support block 2. The top ends of the first movable frame 3 and the second movable frame 4 are slidably connected to both sides of a top block 31. A sewage tank 6 is fixedly installed on the top block 31. A filter grid 9 with a filtration effect is installed in the sewage tank 6. A drain pipe 12 is connected to one side of the sewage tank 6, and the drain pipe 12 is connected to an regulating cylinder 13. A stirring assembly is installed inside the regulating cylinder 13. One side of the regulating cylinder 13 is connected to a biological treatment tank 15 through a connecting pipe 22. One side of the biological treatment tank 15 is connected to a sedimentation filter tank 17, and one side of the sedimentation filter tank 17 is connected to... There is a disinfection tank 18. The biological treatment tank 15, sedimentation and filtration tank 17 and disinfection tank 18 are all hinged with movable cover plates 16. The movable cover plate 16 on the biological treatment tank 15 is equipped with an aeration device 23 and the movable cover plate 16 on the disinfection tank 18 is equipped with an ultraviolet disinfection lamp 28. The sewage tank 6 is fixedly installed with a panel 7. The motor 14 and the pressure pump 24 are both controlled by the panel 7. The first movable frame 3 and the second movable frame 4 are rotatably connected by a rotating shaft 5. The crossbeam of the second movable frame 4 is equipped with an air rod 30 and the air rod 30 is installed at the output end of the cylinder 29. The filter grid 9 is fixedly installed with handles 11 on both sides and limit blocks 10 are installed at the front and rear ends of the filter grid 9. The limit blocks 10 are inserted into the slots 8 at the sewage tank 6. In this embodiment, the filter grid 9 has handles 11 on both sides and limit blocks 10 at the front and rear ends. The limit blocks 10 are inserted into the slots 8 at the sewage tank 6, which facilitates the installation and disassembly of the filter grid 9.
[0018] Example 2 refer to Figures 1 to 2 Example 2 further illustrates Example 1, including a stirring assembly with a motor 14 fixedly mounted on it. A stirring rod 19 is mounted on the output end of the motor 14, and stirring blades 20 are fixedly mounted on both sides of the stirring rod 19. The sedimentation and filtration tank 17 is divided into a sedimentation zone and a filtration zone by a partition 26. A pressure pump 24 is installed in the sedimentation zone, and a pipe 22 is connected to one side of the pressure pump 24 and connects to the filtration zone. A filter screen 27, which is an activated carbon filter screen, is installed in the filtration zone. A packing layer 21 is installed at the bottom of the biological treatment tank 15. In this embodiment, the filtration zone is equipped with an activated carbon filter 27, which can further filter impurities in the wastewater. The bottom of the biological treatment tank 15 has a packing layer 21, providing a place for microorganisms to grow and attach, thus enhancing the biological treatment effect.
[0019] In practical application, the wastewater first enters the wastewater tank 6 and undergoes preliminary filtration through the filter screen 9 to remove large particulate impurities. Operators can easily install and remove the filter screen 9 using the handle 11. The cooperation between the limiting block 10 and the slot 8 ensures the stability of the filter screen 9 installation. The pre-filtered wastewater flows into the regulating cylinder 13 through the drain pipe 12. Activating the control button on the panel 7 causes the motor 14 to drive the stirring rod 19 and stirring blades 20 to rotate, stirring the wastewater in the regulating cylinder 13. Chemicals can be added to the regulating cylinder 13 as needed to ensure thorough mixing of the wastewater and chemicals. The mixed wastewater then enters the biological treatment tank 15 through the connecting pipe 22. The packing layer 21 at the bottom of the biological treatment tank 15 provides a growth environment for microorganisms, which decompose and transform organic matter in the wastewater. Simultaneously, the aeration device 23 aerates the biological treatment tank 15, providing sufficient oxygen to the microorganisms and promoting their metabolic activities. The biologically treated wastewater flows into the sedimentation zone of the sedimentation filter tank 17, where some impurities settle. After a period of sedimentation, the pressurization pump 24 is started to pressurize the settled wastewater into the filtration zone through the pipe 25. The activated carbon filter screen 27 in the filtration zone further filters the wastewater to remove residual impurities. The wastewater that has been settled and filtered flows into the disinfection tank 18. The ultraviolet disinfection lamp 28 on the movable cover plate 16 of the disinfection tank 18 disinfects the wastewater and kills harmful microorganisms such as bacteria and viruses in the wastewater.
