Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to an environmentally friendly integrated sewage treatment device. Background Art

[0002] The process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. Sewage treatment includes multiple steps, including neutralization, filtration, flocculation and sedimentation, anaerobic decomposition, aerobic decomposition, etc. Therefore, in different treatment steps, it is necessary to use a pipeline system to frequently transport the sewage in the treatment process.

[0003] In the prior art, when sewage is transferred through a pipeline system during the sedimentation and anaerobic decomposition process, a large amount of sediment will be generated in the water body after the flocculant is added, which will adhere to the inner wall of the pipe and cause blockage, and it is difficult to clean. At the same time, sludge materials containing a large number of anaerobic microorganisms are required in the anaerobic treatment process. This part of the material can be recycled for a long time, but the impurities generated after the wastewater is settled will be directly mixed with the sludge part as a whole, resulting in a continuous increase in the amount of sludge. This part of the sediment cannot be discharged in time, which will reduce the efficiency of anaerobic bacteria in decomposing biodegradable organic matter in sewage, and the remaining anaerobic bacteria will be greatly reduced when discharged.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] See also Figures 1 to 6The present invention provides the following technical solutions: an environmentally friendly integrated sewage treatment equipment, comprising an integrated equipment body, the integrated equipment body comprising a sedimentation tank 1, an anaerobic tank 2, a connecting mechanism 3 and a drainage component 5, an injection port 7 is provided at the top of the sedimentation tank 1, a plug-in pipe 11 is connected to the bottom of the sedimentation tank 1, the top of the connecting mechanism 3 is sleeved on the surface of the plug-in pipe 11, a socket 9 is provided at the top of the anaerobic tank 2, a support plate 10 is installed on the outside of the socket 9, the bottom of the connecting mechanism 3 is embedded in the inside of the socket 9, a driving mechanism 4 is installed at the top of the anaerobic tank 2, and the driving mechanism 4 is connected to the connecting mechanism 3, a mud discharge pipe 8 is connected to the side bottom of the anaerobic tank 2, and an inner sleeve 14 is provided inside the anaerobic tank 2, the central axis of the inner sleeve 14 coincides with the central axis of the connecting mechanism 3 and the sedimentation tank 1, and a drainage component 5 is installed at the inner top of the anaerobic tank 2. When the environmentally friendly integrated sewage treatment equipment is used, the sewage to be purified is directly injected from the injection port 7 at the top into the sedimentation tank 1, and mixed with the added flocculant in the sedimentation tank 1, so that some of the tiny suspended particles inside the sewage are aggregated to form larger flocs, which are convenient for sedimentation and precipitation, and can aggregate oil pollutants, organic COD, heavy metal ions, fluoride ions and other components in the sewage. After the flocculation and sedimentation are completed, it falls from the bottom connecting mechanism 3 to the anaerobic tank 2 at the bottom, and finally the degradable organic matter inside the anaerobic tank 2 is decomposed by anaerobic bacteria. After the decomposition is completed, the purified sewage can be pumped out through the drainage component 5, and the settled impurities are also independently pumped out.

[0028] In this embodiment, the connecting mechanism 3 includes a rotating column 19 and a docking sleeve 21. A through hole 20 is opened in the middle of the rotating column 19. The plug-in tube 11 is inserted downward from the inside of the through hole 20. A pressure plate 22 is provided at the bottom of the rotating column 19. A docking sleeve 21 is installed at the bottom of the pressure plate 22. A scraper rod 23 is connected to the inner side of the bottom of the docking sleeve 21. The bottom of the sedimentation tank 1 is a conical structure, and the scraper rod 23 is respectively fitted with the bottom of the sedimentation tank 1 and the inner wall of the plug-in tube 11. The surface of the support plate 10 is embedded with ball bearings, and the pressure plate 22 presses on the ball bearings on the surface of the support plate 10.

[0029] Specifically, the sedimentation tank 1 and the anaerobic tank 2 are supported by the vertical plate 6, so the middle connecting mechanism 3 can be directly inserted into the top receiving port 9 of the anaerobic tank 2, and the plug-in tube 11 side connected to the sedimentation tank 1 at the top is embedded in the through hole 20. Subsequently, the sewage mixed with the flocculant inside the sedimentation tank 1 can fall into the plug-in tube 11 along the bottom of the sedimentation tank 1, and fall into the receiving port 9 at the bottom and the anaerobic tank 2 at the bottom along the plug-in tube 11. The whole process can prevent the sewage from overflowing from the side of the connecting mechanism 3.

[0030] In this embodiment, the driving mechanism 4 includes a motor 12 and a driving shaft 13, the outer shell of the motor 12 is embedded in the top of the anaerobic tank 2, the driving shaft 13 is installed on the output end of the motor 12, a driving gear 24 is installed on the surface of the driving shaft 13, a transmission belt 25 is sleeved on the side of the driving gear 24, a driven gear 26 is installed on the side of the rotating column 19, the other end of the transmission belt 25 is sleeved on the side of the driven gear 26, the docking sleeve 21 is embedded in the interior of the anaerobic tank 2, and the side of the docking sleeve 21 is in contact with the inner wall of the socket 9, two scraper rods 23 are provided, and the two scraper rods 23 are symmetrically installed on the inner wall of the plug-in tube 11, and a gap is provided between the surface of the plug-in tube 11 and the inner wall of the through hole 20. The sedimentation tank 1 is set at the top, the anaerobic tank 2 is set at the bottom, and the two treatment tanks are connected by a connecting mechanism 3. Therefore, the sewage after the flocculant mixing reaction can be directly transported from the connecting mechanism 3 to the anaerobic tank 2 at the bottom, and the connecting mechanism 3 can be controlled to rotate with the help of the driving mechanism 4, so as to achieve the scraping and cleaning effect of the plug-in tube 11 inside the connecting mechanism 3, avoiding the problem that a large amount of impurities generated after the sewage is settled adhere to the inner wall of the plug-in tube 11, which is easy to cause blockage.

[0031] Specifically, after starting the motor 12, the motor 12 drives the driving shaft 13 to rotate, and the driving shaft 13 can drive the active gear 24 and the transmission belt 25 on the surface to rotate, thereby controlling the driven gear 26 on the connecting mechanism 3 to rotate. After the entire connecting mechanism 3 rotates, the scraper rod 23 connected on the inside can be rotated along the inner wall of the plug-in tube 11 and the bottom of the sedimentation tank 1, so as to realize the scraping and cleaning process of the impurities adhered to the inner wall of the plug-in tube 11 and the bottom of the sedimentation tank 1. In addition, since the bottom of the connecting mechanism 3 is pressed on the support plate 10 with the ball by the pressure plate 22, it can ensure that the connecting mechanism 3 can be efficiently transmitted.

[0032] In this embodiment, a flocculant storage bin 17 is installed on the top of the sedimentation tank 1, and the flocculant storage bin 17 is annular in structure as a whole. A flocculant delivery port 18 is provided on the top of the flocculant storage bin 17, and a connecting column 16 is provided at the bottom of the flocculant storage bin 17. A diverter plate 15 is installed at the bottom of the connecting column 16. The diverter plate 15 is annular in structure as a whole, and a plurality of holes are provided at the bottom of the flocculant storage bin 17. The flocculant inside the flocculant storage bin 17 falls onto the surface of the diverter plate 15 through the holes at the bottom, and the central axis of the diverter plate 15 coincides with the central axis of the top injection port 7. An annular flocculant storage bin 17 is provided on the top of the sedimentation tank 1, and the injected sewage can be evenly diffused toward the surroundings by means of the diverter plate 15. The flocculant can be quickly and evenly mixed with the sewage in the diversion process by cooperating with the flocculant storage bin 17, thereby improving the mixing efficiency of the flocculant.

[0033] Specifically, the flocculant is introduced into the flocculant storage bin 17 from the flocculant introduction port 18 at the top. Since a plurality of holes are provided at the bottom of the flocculant storage bin 17, and the spacing between each hole is the same, after the external sewage is injected into the sedimentation tank 1 from the injection port 7, it will first fall onto the diverter plate 15, and diffuse and flow evenly toward the side of the diverter plate 15. During the diffusion process, it can mix and contact with the flocculant falling from the top, so that the flocculant can quickly merge with the sewage in the diversion diffusion process.

[0034] In this embodiment, the drainage component 5 includes a drainage pipe 27, an outer extraction pipe 29 and an inner extraction pipe 28, the inner extraction pipe 28 is connected to the end of the drainage pipe 27, the outer extraction pipe 29 is connected to the middle position of the drainage pipe 27, and a first floating water pumping port 30 is installed at the end of the inner extraction pipe 28, and a second floating water pumping port 31 is connected to the end of the outer extraction pipe 29, and a baffle 32 is installed at the bottom of the second floating water pumping port 31, and two guide rods 33 are fixedly installed on the surface of the baffle 32, and the guide rods 33 extend upward from the surface of the second floating water pumping port 31, and the top of each guide rod 33 is provided with an outwardly protruding limiting structure. An inner sleeve 14 is provided at the bottom, and sludge containing a large amount of anaerobic bacteria is accumulated on the outside of the inner sleeve 14. The sewage injected subsequently can concentrate the sediment in the inner sleeve 14. Therefore, after all the sewage after anaerobic treatment inside is extracted with the help of the drainage component 5, only the impurities settled in the sewage can be extracted independently, while the sludge part that can be reused is retained, thereby increasing the content of anaerobic bacteria and extending the replacement and treatment cycle of the sludge.

[0035] Specifically, when the sludge accumulated at the bottom of the outer side of the inner sleeve 14 will diffuse the anaerobic bacteria contained in it into the sewage at the top, after the sewage is purified through the anaerobic decomposition process, the sewage inside and outside the inner sleeve 14 can be pumped out from the extraction pipe at the same time through the external water pump connected to the drainage pipe 27, and since each floating water pumping port floats on the surface of the sewage, it can always descend with the extraction of the sewage until all the purified sewage is extracted. After the sewage is pumped out, the baffle 32 at the bottom will fall on the sludge containing a large amount of anaerobic bacteria, and finally the second floating pumping port 31 will fall on the surface of the baffle 32. The baffle 32 is used to block the second floating pumping port 31 to avoid pumping out the sludge at the bottom. The baffle 32 is not provided at the bottom of the first floating pumping port 30 in the inner sleeve 14. Therefore, after the first floating pumping port 30 falls on the settled impurities at the bottom, the impurities at the bottom will continue to be pumped out, thereby achieving the effect of retaining only the sludge.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
