Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to energy-saving and environment-friendly sewage treatment equipment. Background Art

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for drainage into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] When treating large quantities of sewage, it generally includes two aspects: First, it is necessary to remove the more obvious impurities in the sewage (such as floating leaves, branches, pebbles and other particulate impurities), and collect and treat these impurities in a centralized manner. Second, it is necessary to remove impurities by flocculation and sedimentation, that is, to make the suspended particles in the water or liquid aggregate and become larger, or form flocs, thereby accelerating the aggregation of particles and achieving the purpose of solid-liquid separation. This phenomenon or operation is called flocculation; usually, flocculation is implemented by adding appropriate flocculants, whose function is to adsorb particles and "bridge" between particles, thereby promoting aggregation. The mixing uniformity of sewage and flocculants directly affects the effect of flocculation; in order to obtain a better flocculation effect, it is necessary to fully mix the sewage and flocculants, so it is necessary to fully stir them.

[0004] However, in the prior art, the treatment method for the first item is generally to intercept by a fixed trash rack or filter net, but when the trash rack or filter net is blocked, it will affect the flow rate of the sewage, and thus affect its treatment efficiency; the treatment method for the second item is generally to add flocculants to the sewage manually or electrically, and then use a motor to drive a stirring rod to stir the sewage and the flocculant. The disadvantages of this method are as follows: First, the mixing time is long, which affects the flocculation effect of the flocculant and also increases the treatment time of the sewage; second, the amount of flocculant added cannot be flexibly adjusted according to the amount of sewage. If manual addition is used, it is time-consuming and labor-intensive, and if electronic addition is used, the cost is high; third, since the sewage may contain some organic matter, in addition to adding flocculants, it is sometimes necessary to add some microorganisms when treating it, thereby promoting the biological degradation of organic matter. Traditional sewage treatment methods often only focus on adding microorganisms, but ignore their efficiency in degrading organic matter in sewage.

[0005] Therefore, it is necessary to design a new sewage treatment equipment to solve the above problems. Summary of the invention

[0021] The above-mentioned pumping and discharging assembly includes a piston cylinder 23 provided above the box body 1.

[0023] To improve the purification and treatment efficiency of sewage, an air inlet 28 and an air outlet 29 are arranged on the piston cylinder 23. Check valves are arranged at both the air inlet 28 and the air outlet 29. The air outlet 29 is connected to an aeration pipe network 30 arranged in the box body 1 through an air supply pipe 31. This structural design facilitates the aeration treatment of sewage, which not only helps to improve the mixing efficiency of the microbial flocculant and sewage and thus accelerate the flocculation and precipitation efficiency of impurities in the sewage, but also can increase the oxygen concentration in the sewage and improve the degradation efficiency of microorganisms on the organic matter in the sewage.

[0024] The above-mentioned aeration pipe network 30 includes two main pipes 30-1. An air inlet 30-3 connected to the air supply pipe 31 is arranged on one of the main pipes 30-1. A plurality of aeration pipes 30-2 are arranged between the two main pipes 30-1. A plurality of air outlet holes are arranged on the aeration pipes 30-2.

[0025] A sludge level meter 40 is arranged below the deflector 36 in the box body 1. A sludge discharge port 41 is also arranged at the bottom of the box body 1. A sludge discharge pump 43 is arranged below the box body 1. The inlet of the sludge discharge pump 43 is connected to the sludge discharge port 41 through a second connecting pipe 42. The outlet of the sludge discharge pump 43 is connected to one end of a sludge discharge pipe 44. The sludge discharge pump 43 and the sludge level meter 40 are both electrically connected to a controller 45 arranged on the top of the box body 1.

[0026] To further improve the technical advantages of energy conservation, environmental protection and strong practicability of the device, the other end of the second rotating shaft 13 is drivingly connected to a generator 16. The generator 16 supplies power to a storage battery 47 arranged above the box body 1. The storage battery 47 supplies power to the entire device.

[0027] Considering that in the process of sewage purification and treatment, sewage may emit some gases that pollute the environment, such as irritating gases like hydrogen sulfide, in order to facilitate the removal of them, an exhaust port 38 is arranged on the top of the box body 1. A pull-out activated carbon filtration component 39 is arranged at the exhaust port 38.

[0028] To ensure the cleanliness of the water discharged from the drain port 4, the above-mentioned drain port 4 is located below the inclined tube filler 32.

[0029] To prevent some large impurities in the box body 1 from entering the water storage tank 3, a filter screen 46 is provided at the position on the inner wall of the water storage tank 3 corresponding to the drain port 4.

[0030] It should be noted that the impurity removal component is close to the top of the sewage pipe 5 to reduce the impact force of the sewage on the cleaning brush 8.

[0031] The specific working principle of the present invention is as follows: First, the mud level threshold measured by the mud level gauge 40 is set through the controller 45. When the mud level value exceeds the highest value of the threshold, the controller 45 starts the sludge pump 43 to discharge sludge. When the mud level value is lower than the lowest value of the threshold, the controller 45 shuts down the sludge pump 43.

[0032] When the device is working, sewage is discharged from the top of the vertically arranged sewage pipe 5. The sewage first passes through the cleaning brush 8 in the impurity removal component for impurity removal and then continues to fall. The falling water impacts on the fan blades 14, causing the fan blades 14 to rotate. Then, the second rotating shaft 13 rotates. When the second rotating shaft 13 rotates, the driving gear 15 drives the driven gear 18 to rotate, thereby causing the rotating pipe 17 to rotate. When the rotating pipe 17 rotates, it drives the reducer 19 to operate through the gear transmission structure 20. Then, the power output end of the reducer 19 drives the half-angle gear 21 to rotate.

[0033] When the transmission teeth of the half-angle gear 21 mesh with the rack 22 for transmission, the rack 22 moves towards the rotating pipe 17. Then, the piston rod 25 drives the piston plate 24 to move. The treatment liquid in the storage tank 37 enters the left area of the piston plate 24 in the piston cylinder 23. At the same time, the air on the right side of the piston plate 24 in the piston cylinder 23 is discharged from the air outlet 29, enters the aeration pipe network 30 through the air supply pipe 31, and then is discharged from the air outlet holes on the aeration pipe 30-2 to aerate the sewage. When the transmission teeth of the half-angle gear 21 disengage from the rack 22, under the action of the tension spring 49, the piston plate 24 in the piston cylinder 23 moves towards the liquid outlet 27. The outside air enters the piston cylinder 23 from the air inlet 28. The treatment liquid in the piston cylinder 23 is discharged from the liquid outlet 27, enters the rotating pipe 17 through the connecting pipe 1, and then is discharged from the liquid outlet 27 on the spray pipe and mixed with the sewage. The sewage mixed with the treatment liquid undergoes flocculation precipitation after passing through the inclined tube filler 32. Under the turbulence action of the pulp board 35, the impurities in the sewage sink into the sludge storage area, and the purified water is discharged from the drain port 4 into the water storage tank 3 for subsequent use.

[0034] It should be noted that when the second rotating shaft 13 rotates, the second rotating shaft 13 drives one of the first rotating shafts 7 in the impurity removal component to rotate through the belt pulley transmission structure 48. Then, through the meshing transmission gears 11, the other first rotating shaft 7 is driven to rotate. Thus, the cleaning brush 8 continuously cleans the sewage, and the impurities attached to the cleaning brush 8 are scraped off. Finally, the staff opens the sealing plug at the slag discharge port 9 to clean out the impurities.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present invention or make equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
