Description

Technical Field

[0001] This invention relates to the field of rural sewage treatment equipment technology, specifically to a phosphorus removal device suitable for the renovation of rural sewage treatment sites. Background Technology

[0002] Currently, facilities in the field of phosphorus removal include phosphorus removal plates and chemical dosing tanks. The former has poor phosphorus removal effect, while the latter has poor mixing effect and cannot simultaneously achieve the functions of coagulation, flocculation, and sedimentation, resulting in unstable effluent.

[0003] Therefore, we propose a phosphorus removal device suitable for the renovation of agricultural wastewater treatment plants. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a phosphorus removal device suitable for the renovation of agricultural wastewater treatment plants. It overcomes the deficiencies of existing technologies, has a reasonable design and compact structure, and solves the technical problems of existing facilities being unable to simultaneously achieve adequate storage and mixing effects, as well as unstable effluent.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A phosphorus removal device suitable for the renovation of agricultural wastewater treatment plants includes a clarification tank, a dosing mechanism, and an air supply mechanism; characterized in that:

[0009] The clarification tank includes a first cylinder, a second cylinder, and a third cylinder, all of which are circular and coaxially arranged from the inside out. A mixer is installed inside the first cylinder. Water passage holes are opened on the side walls of the first, second, and third cylinders. The water passage holes of adjacent cylinders are alternately arranged at the upper and lower parts of the cylinders. The water passage hole of the first cylinder is located at the upper part of the cylinder. The water inlet pipe of the clarification tank is connected to the first cylinder. The water flows from top to bottom between the cylinders. The sludge discharge pipe of the clarification tank is connected to the second cylinder.

[0010] The dosing mechanism includes a dosing tank and a dosing pump, wherein the dosing tank delivers a quantitative amount of medicine to the first cylinder via the dosing pump;

[0011] One of the air supply pipes of the air supply mechanism is connected to the first cylinder to achieve aeration.

[0012] Furthermore, an annular ramp is provided between the third cylinder and the second cylinder, with the upper edge of the annular ramp being sealed to the inner wall of the third cylinder and its lower edge being sealed to the outer wall of the second cylinder.

[0013] Furthermore, the device includes a clear water tank, a water quality detector, and a controller. The water passage hole of the third cylinder of the clarification tank is connected to the clear water tank through a pipeline. The water quality detector, the dosing pump, and the air pump of the air supply mechanism are electrically connected to the controller. The water quality detector is used to detect the water quality in the clear water tank.

[0014] Furthermore, the water body detector is an SS detector.

[0015] Furthermore, an annular and coaxial water outlet weir is fixed to the upper part of the inner side wall of the third cylinder, and the groove formed by the water outlet weir and the third cylinder is connected to the water passage hole at the upper part of the third cylinder.

[0016] Furthermore, the mixer employs a swirl aerator, and one air pipe of the air supply mechanism is connected to the swirl aerator.

[0017] Furthermore, the water passage holes, the water outlet of the inlet pipe, and the swirl aerator of the first cylinder are distributed sequentially from top to bottom.

[0018] Furthermore, the sludge discharge pipe extends from top to bottom to the bottom of the second cylinder and forms a sludge discharge inlet. Another air pipe of the air supply mechanism is connected to the sludge discharge inlet to realize air-lift sludge discharge.

[0019] Furthermore, the second air tube, i.e. another air tube, has a connector at its lower end. The upper end of the connector is inserted into the bottom opening of the sludge discharge pipe and is sealed to the sludge discharge pipe through a sealing ring.

[0020] The lower end sidewall of the sludge discharge pipe has two sets of sludge discharge inlets that are vertically spaced apart.

[0021] The lower end of the sludge discharge pipe is fitted with a rubber sleeve. The middle area of ​​the rubber sleeve has one or a pair of spaced protrusions. One or a pair of protrusions are embedded in one set of sludge discharge inlets. The upper and lower ends of the rubber sleeve are both fitted with reinforcing rings. The reinforcing rings are fixed to the second air pipe through a first connector. There is a hollow space between the first connector and the protrusions of the rubber sleeve.

[0022] The third air pipe of the air supply mechanism is connected to the air bag. The air bag's inlet and outlet valves are electrically connected to the controller. The air bag's inflation and deflation drive the mud discharge pipe to rise and fall.

[0023] Furthermore, the airbag is mounted on the top of the clarification tank via a base plate, and a lifting platform is mounted on the upper part of the airbag. The lifting platform is vertically guided and engaged with the base plate via guide columns, and the sludge discharge pipe is mounted on the lifting platform via a second connector.

[0024] Furthermore, the sludge discharge pipe is fixed with an upper limit sleeve and a lower limit sleeve on the upper and lower sides of the two sets of sludge discharge inlets, respectively. When the sludge discharge pipe moves upward until the reinforcing ring abuts against the lower limit sleeve, the protrusion of the rubber sleeve is embedded in the lower set of sludge discharge inlets to clear the blockage. At the same time, the upper sludge discharge inlet is exposed to keep the sludge discharge unobstructed.

[0025] (III) Beneficial Effects

[0026] This invention provides a phosphorus removal device suitable for the renovation of agricultural wastewater treatment stations. It features land saving, high efficiency, intelligence, and energy saving, and is universally applicable to the renovation of current agricultural wastewater treatment stations. It also shows promising application prospects for the renovation of agricultural wastewater treatment stations where TP (total phosphorus) levels at national and provincial monitoring sections do not meet standards. Details are as follows:

[0027] 1. The clarification tank innovatively adopts an integrated ring structure, which is quite different from the traditional method. The central inlet and peripheral outlet can enhance the uniformity and flexibility of water distribution. Moreover, the water forms a baffle through the connecting parts (water passage holes) of each cylinder, which reduces short-circuiting and cross-flow, and strengthens the coagulation and flocculation process. In addition, the tank layout is more convenient and saves space.

[0028] 2. The clarifier adopts aeration swirl mixing, which is different from the traditional subsurface mixer. It uses less electromechanical equipment, thereby reducing the intensity of maintenance and replacement and lowering operation and maintenance costs.

[0029] 3. The swirling agitator can achieve spiral ascent within the guide tube, ensuring thorough mixing of the reagent and the incoming water. Furthermore, the degree of mixing can be adjusted by regulating the valve of the air pump, achieving intelligent operation.

[0030] 4. The core component of the swirling agitator is a steel swirling aerator head. Considering that it is prone to clogging in the future, the air pipe is equipped with an oil valve to facilitate subsequent disassembly, cleaning and replacement.

[0031] 5. The sludge discharge pipe adopts an air-lift design, which discharges flocculated sludge once a week, further reducing the need for electromechanical equipment and lowering operation and maintenance costs.

[0032] 6. The effluent from the clarifier is connected to a water quality analyzer for testing. The preferred water quality analyzer is an SS analyzer. Since TP monitors are too expensive and not cost-effective for agricultural wastewater treatment sites, considering the good linear correlation between SS and TP, SS is used to qualitatively analyze the concentration of TP, thereby achieving online monitoring.

[0033] 7. By initiating a signal through a response port, the system intelligently monitors, judges, and controls the air pump valve and the dosing pump, forming a closed loop and ultimately achieving online monitoring and debugging. Attached Figure Description

[0077] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0078] See attached document Figure 1-3 A phosphorus removal device suitable for the renovation of agricultural wastewater treatment plants includes a clarification tank 1, a clear water tank 4, a dosing mechanism 2, an aeration mechanism, a water quality detector 5, and a controller (the controller is not shown in the figure, but it and the water pump of the aeration mechanism are both built into the control cabinet 3).

[0079] The clarification tank 1 includes a first cylindrical body 11, a second cylindrical body 12, and a third cylindrical body 13, all of which are circular and coaxially arranged from the inside to the outside. A mixer is installed inside the first cylindrical body 11. Water passage holes are opened on the side walls of the first cylindrical body 11, the second cylindrical body 12, and the third cylindrical body 13, respectively, which are the first water passage hole 111, the second water passage hole 121, and the third water passage hole. The first water passage hole 111, the second water passage hole 121, and the third water passage hole are alternately arranged along the upper and lower parts of the cylindrical body. The first water passage hole 111 is located on the upper part of the side wall of the first cylindrical body 11 (correspondingly, the second water passage hole 121 is located on the lower part of the side wall of the second cylindrical body 12, preferably at the bottom of the side wall, and the third water passage hole is located on the upper part of the side wall of the third cylindrical body 13). The water inlet pipe 15 of the clarification tank 1 is connected to the first cylindrical body 11. The water flows from top to bottom between the cylindrical bodies. The sludge discharge pipe 16 of the clarification tank 1 is connected to the second cylindrical body 12.

[0080] The dosing mechanism 2 includes a dosing tank 21 and a dosing pump 22. The dosing tank 21 contains PAC and PAM. The dosing tank 21 delivers a quantitative amount of drugs to the first cylinder 11 through the dosing pump 22 (the input end of the dosing pump 22 is connected to the dosing tank 21 through the dosing pipe 23, and its output end is connected to the first cylinder 11 through the dosing pipe 23).

[0081] The first air pipe 61 of the air supply mechanism is connected to the first cylinder 11 to realize aeration;

[0082] The clear water tank 4 is connected to the water passage hole of the third cylinder 13 of the clarification tank 1 through a pipeline to realize the storage of clear water;

[0083] The water quality detector 5 is an SS detector. The probe of the water quality detector 5 is built into the clear water tank 4 and is used to detect the water quality in the clear water tank 4.

[0084] The controller is electrically connected to the water body detector 5, the dosing pump 22, and the air pump of the air supply mechanism, respectively.

[0085] After the secondary effluent from the site enters the integrated clarifier 1, TP is removed through flocculation and sedimentation. The effluent then enters the clear water tank 4. If the SS (suspended solids) level in the effluent exceeds a certain standard, the control cabinet 3 responds to adjust the dosage of the dosing pump 22 and the intensity of aeration and stirring in the dosing well, achieving online monitoring. If the TP in the secondary influent meets the discharge standards, this facility may not require chemical dosing, and the integrated clarifier 1 and clear water tank 4 serve as a clear water corridor.

[0086] In this embodiment, the bottoms of the first cylinder 11, the second cylinder 12, and the third cylinder 13 of the clarification tank 1 are encapsulated by the same base plate / base, and the upper part is covered by a top cover with a manhole 19 in the center of the top cover for easy maintenance.

[0087] In this embodiment, the sludge discharge pipe 16 extends from top to bottom to the bottom of the second cylinder 12. The lower opening of the sludge discharge pipe 16 is the sludge discharge inlet. The second air pipe 62 of the air supply mechanism is connected to the sludge discharge inlet to achieve air-lift sludge discharge. An annular ramp 18 is provided between the third cylinder 13 and the second cylinder 12. The upper edge of the annular ramp 18 is sealed to the inner wall of the third cylinder 13, and its lower edge is sealed to the outer wall of the second cylinder 12. During continuous operation of the equipment, the sludge continuously settles and concentrates in the sludge zone under the action of gravity. After reaching the scale required for sludge discharge, the air-lift solenoid valve is activated, and the mud-water mixture is discharged outward under the action of air-lift. Because the sludge discharge pipe is designed next to the manhole, the annular ramp can reduce the liquid level of the mud-water mixture after the sludge discharge pipe is activated. Under the combined action of gravity and air-lift suction, it converges towards the sludge discharge pipe, thereby reducing the dead corners formed by sludge deposited in the corners of the outer wall due to being too far from the sludge discharge pipe. In other embodiments, such as Figure 4 As shown, the bottom outer edge of the second cylinder 12 can also be set as conical and smoothly connected with the annular slope to further reduce dead angles.

[0088] In this embodiment, an annular and coaxial water outlet weir 14 is fixed on the upper part of the inner side wall of the third cylinder 13, and the groove formed by the water outlet weir 14 and the third cylinder 13 is connected to the water passage hole on the upper part of the third cylinder 13.

[0089] In this embodiment, the mixer is a cyclone aerator 17 (e.g., the cyclone aerator 17TL-1000 from Shanghai Taiyu Energy Saving and Environmental Protection Technology Co., Ltd.), and one air pipe of the air supply mechanism is connected to the cyclone aerator 17. The water passage hole of the first cylinder 11, the water outlet of the water inlet pipe 15, and the cyclone aerator 17 are distributed sequentially from top to bottom.

[0090] In other embodiments, such as Figure 5 , Figure 6 As shown, the second air tube, i.e. another air tube, has a connector 621 connected to its lower end. The upper end of the connector 621 is inserted into the bottom opening of the mud discharge pipe 16 and is sealed with the mud discharge pipe through the sealing ring 161.

[0091] The lower side wall of the sludge discharge pipe is provided with two sets of vertically spaced sludge discharge inlets. Preferably, the outer end of the sludge discharge inlet is chamfered to facilitate the protrusion from the sludge discharge inlet.

[0092] A rubber sleeve 75 is fitted over the sludge discharge pipe. The middle area of ​​the rubber sleeve 75 has one or a pair of spaced protrusions. One or a pair of protrusions are embedded in one of the sludge discharge inlets. The upper and lower ends of the rubber sleeve 75 are both embedded with reinforcing rings 781 (the rubber sleeve 75 can be fixed to the reinforcing rings 781 by glue or vulcanization). The reinforcing rings 781 are fixed to the second air pipe by a first connector 78 (preferably, the reinforcing rings 781 and the first connector 78 are integrally formed). A hollow 782 is provided between the first connector 78 and the protrusions of the rubber sleeve 75. The hollow 782 can provide a deformation area for the rubber sleeve 75, so that the protrusions can be easily removed from the sludge discharge inlets and the protrusions can be prevented from breaking.

[0093] The third air pipe 63 of the air supply mechanism is connected to the airbag. The airbag's inlet and outlet valves 64 are electrically connected to the controller. The airbag's inflation and deflation drive the mud discharge pipe to rise and fall. A corrugated hose can be installed between the vertical and horizontal sections of the mud discharge pipe. The corrugated hose can expand, contract, and deform to adapt to the rising and falling.

[0094] Specifically, the airbag is mounted on the top of the clarifier via a base plate 72, and a lifting platform 71 is mounted on the upper part of the airbag. The lifting platform 71 is vertically guided and engaged with the base plate 72 via guide posts 73, and the sludge discharge pipe is mounted on the lifting platform 71 via a second connector 74.

[0095] Specifically, the sludge discharge pipe is fixed with an upper limit sleeve 76 and a lower limit sleeve 77 on the upper and lower sides of the two sets of sludge discharge inlets, respectively. When the sludge discharge pipe moves upward until the reinforcing ring 781 abuts against the lower limit sleeve 77, the protrusion of the rubber sleeve 75 is embedded in the lower set of sludge discharge inlets to clear the blockage. At the same time, the upper sludge discharge inlet is exposed to keep the sludge discharge unobstructed. Conversely, when the sludge discharge pipe moves downward until the reinforcing ring 781 abuts against the upper limit sleeve 76, the protrusion of the rubber sleeve 75 is embedded in the upper set of sludge discharge inlets to clear the blockage. At the same time, the lower sludge discharge inlet is exposed.

[0096] The reinforcement ring 781 ensures that when the rubber sleeve 75 moves relative to the sludge discharge pipe, both ends of the rubber sleeve 75 remain tightly fitted to the sludge discharge pipe, greatly reducing or even preventing the settled sludge from falling between the rubber sleeve 75 and the sludge discharge pipe. The sludge that falls between the rubber sleeve 75 and the sludge discharge pipe will cause the rubber sleeve 75 to deform after drying, and the protrusion 751 will not be able to be fully embedded in the sludge discharge inlet, affecting the unblocking effect.

[0097] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0098] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
