Description

Technical Field

[0001] The utility model relates to a sewage treatment device, in particular to a multi-stage integrated filtering sewage treatment device. Background Art

[0002] In modern society, the discharge of sewage is increasing. A large amount of sewage has caused great damage to the environment. Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment is widely used in fields such as construction, agriculture, transportation, and energy. General urban sewage includes the general term of sewage discharged into the urban sewage system. In a combined sewer system, it also includes industrial wastewater and intercepted rainwater, etc. Sewage treatment technologies are classified according to the treatment degree. Mild treatment uses screening, sedimentation, etc. to remove insoluble suspended solids and floating substances in sewage. Moderate treatment mostly uses biological treatment methods, that is, through the metabolic action of microorganisms for material transformation. Severe treatment is to use coagulation, filtration, ion exchange, reverse osmosis and other methods to remove difficult-to-dissolve organic matter, phosphorus, nitrogen and other nutrient substances in sewage on the basis of the above treatment. Existing treatment devices mostly use multi-stage treatment methods for treatment. And the existing treatment methods mostly first pass through a primary sedimentation tank, then through ion exchange or electro-electrodialysis. Finally, microorganisms are used to oxidize and decompose organic matter in sewage and carry out metabolism. Existing treatment devices generally have relatively cumbersome treatment means and average treatment effects. The treatment devices often have low treatment efficiency and complex processes, and the travel of sewage during filtration is not long enough, resulting in incomplete filtration.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a sewage treatment device with multi-stage integrated filtration, including a sewage storage tank 1, a first sewage treatment tank 2, a second sewage treatment tank 3, a third sewage treatment tank 4, and a sewage recovery tank 5.

The second sewage treatment tank 3 includes a coarse filter screen 8, a fine filter screen 9, and an impurity treatment tank 10. The impurity treatment tank 10 is installed at the end of the first sewage treatment tank 2. The impurity treatment tank 10 includes a metal impurity adsorption device 11 and a layered filter 12. A waste box 13 is also connected to the rear end of the impurity treatment tank 10. The third sewage treatment tank 4 includes an adsorption plate 14 and a pumping device 15. The sewage storage tank 1 is connected to the first sewage treatment tank 2 through the pumping device 15.

The second sewage treatment tank 3 is connected to the third sewage treatment tank 4 through the pumping device 15. The third sewage treatment tank 4 is connected to the sewage recovery tank 5 through the pumping device 15.

[0025] Specifically, the pumping device 15 includes a water pump 16 and a drain pipe 17. The drain pipe 17 in the second sewage treatment tank 3 passes through the coarse filter screen 8 and the fine filter screen 9. Through the above settings, the sewage can pass through the coarse filter screen 8 and the fine filter screen 9 in sequence, effectively removing large particulate impurities and tiny suspended matters in the sewage. The coarse filter screen 8 is mainly responsible for intercepting larger solid impurities to prevent them from entering the subsequent treatment links. The entire sewage treatment device with multi-stage integrated filtration has a clever design and a reasonable layout.

[0026] In some embodiments, a sealing ring may be provided at the place where the drain pipe 17 passes through the coarse filter screen 8 and the fine filter screen 9, so that the filtering effect of the coarse filter screen 8 and the fine filter screen 9 is better, and impurities will not pass through the gaps between the drain pipe 17 and the coarse filter screen 8 and the fine filter screen 9.

[0027] Specifically, the third sewage treatment tank 4 further includes a filter element 18. The drain pipe 17 in the third sewage treatment tank 4 passes through the filter element 18, and one end of the drain pipe 17 is located above the adsorption plate 14. By providing the filter element 18, impurities can be further treated.

[0028] In some embodiments, a sealing ring may be provided at the place where the drain pipe 17 passes through the filter element 18, so that the filtering effect is better, and impurities will not pass through the gaps between the drain pipe 17 and the filter element 18.

[0029] Specifically, the metal impurity adsorption device 11 includes magnetic bars 20 and baffles 21. A number of waste recycling compartments 22 are provided in the waste bin 13. With the above settings, the metal impurity adsorption device 11 can effectively remove ferromagnetic impurities in the sewage and improve the treatment effect. The magnetic bars 20 play a role in intercepting and adsorbing ferromagnetic impurities in the impurity treatment tank 10, while the baffle 21 is used to prevent impurities from splashing out or flowing back during the treatment process. The waste recycling compartments 22 in the waste bin 13 are used to classify and collect different types of waste, facilitating subsequent treatment and recycling.

[0030] Specifically, a number of air guns 23 are also provided on both sides of the first sewage treatment tank 2. The air outlet direction of the air guns 23 faces into the first sewage treatment tank 2. By providing the air guns 23, impurities can be better treated in the first sewage treatment tank 2, preventing sediment from accumulating at the bottom of the tank.

[0031] Specifically, liquid level detection devices 24 are also provided in the first sewage treatment tank 2, the second sewage treatment tank 3, and the third sewage treatment tank 4. By providing the liquid level detection devices 24, the liquid level conditions in the first sewage treatment tank 2, the second sewage treatment tank 3, and the third sewage treatment tank 4 can be monitored in real time, ensuring that the sewage can pass through each treatment unit in sequence and at a set flow rate, thereby achieving the expected treatment effect. When the liquid level in a certain sewage treatment tank is too high or too low, the liquid level detection device 24 can issue an alarm to remind the operator to make timely adjustments to avoid sewage overflow or insufficient treatment.

[0032] Specifically, a control panel 25 and a ladder 26 are also provided outside the first sewage treatment tank 2. The pumping devices 15 in the sewage storage tank 1, the first sewage treatment tank 2, the second sewage treatment tank 3, the third sewage treatment tank 4, and the sewage recovery tank 5 are all electrically connected to the control panel 25. With such a setting, it is convenient for the user to operate. The pumping devices 15 in the sewage storage tank 1, the first sewage treatment tank 2, the second sewage treatment tank 3, the third sewage treatment tank 4, and the sewage recovery tank 5 can be controlled through the control panel 25. The ladder 26 is also provided to facilitate the user's maintenance at any time.

[0033] Specifically, the sewage storage tank 1, the first sewage treatment tank 2, the second sewage treatment tank 3, the third sewage treatment tank 4, and the sewage recovery tank 5 are all made of high-strength corrosion-resistant materials, ensuring the stability and reliability of the sewage treatment device during long-term and high-load operation.

[0034] Specifically, the stirrer 7 in the first sewage treatment tank 2 is set as an electric stirrer 7 with adjustable speed, and the blades of the stirrer 7 are designed in a spiral shape. By designing the blades of the stirrer 7 in a spiral shape, the stirrer 7 can generate a stronger vortex effect during operation, effectively turning and mixing the impurities in the sewage, and improving the treatment efficiency. At the same time, the design of adjustable speed enables the stirrer 7 to flexibly adjust the speed according to the conditions of different sewage and treatment requirements to achieve the best treatment effect.

[0035] A specific application example of this embodiment is as follows:

[0036] When this device is in use, the sewage to be treated is introduced into the sewage storage tank 1, and the pumping device 15 is started through the control panel 25 to pump the sewage from the sewage storage tank 1 into the first sewage treatment tank 2. In the first sewage treatment tank 2, the sewage undergoes preliminary stirring and mixing under the combined action of the horizontal scraper 6 and the stirrer 7, effectively preventing sediment from accumulating at the bottom of the tank and at the same time making the impurities in the sewage evenly distributed. The spiral blades of the stirrer 7 and the air gun 23 generate a strong vortex effect, which helps to turn and mix the impurities, improving the subsequent treatment efficiency, and the sediment enters the impurity treatment tank 10. In the impurity treatment tank 10, the metal impurity adsorption device 11 adsorbs ferromagnetic impurities in the sewage through the magnetic grid 20 to improve the treatment effect. At the same time, the layered filter 12 performs layered treatment on different components in the sewage to further remove impurities in the sewage. The treated impurities are collected in the waste box 13 and classified and collected through the waste recycling grid 22, which is convenient for subsequent treatment and recycling.

[0037] The sewage preliminarily treated in the first sewage treatment tank 2 is pumped into the second sewage treatment tank 3 through the pumping device 15. In the second sewage treatment tank 3, the sewage first passes through the coarse filter screen 8 to intercept larger solid impurities and prevent them from entering the subsequent treatment links. Subsequently, the sewage passes through the fine filter screen 9 to further remove the tiny suspended matters in the sewage. The combined use of the coarse and fine filter screens 9 effectively improves the efficiency and effect of sewage treatment.

[0038] Subsequently, the sewage enters the third sewage treatment tank 4. In the third sewage treatment tank 4, the sewage first passes through the filter element 18 for filtration to further remove impurities in the sewage. Through the setting of the flip cover plate 19, the use state of the adsorption plate 14 can be adjusted according to actual needs to ensure that it always maintains a good adsorption effect.

[0039] Finally, the sewage treated in the third sewage treatment tank 4 is pumped into the sewage recovery tank 5 through the pumping device 15.
