Abstract
Description
Technical Field
[0001] The utility model relates to a wastewater treatment device, in particular to a breeding wastewater purification device, and belongs to the technical field of wastewater treatment equipment. Background Art
[0002] Aquaculture wastewater is a high-concentration organic wastewater containing a large number of pathogens. When a large amount of organic matter enters the water, the decomposition of the organic matter will consume a large amount of dissolved oxygen in the water, causing the water to stink and leading to the death of a large number of aquatic organisms. Nitrogen and phosphorus can cause eutrophication of the water. Under anaerobic conditions, livestock and poultry aquaculture wastewater will produce large amounts of malodorous gases such as NH3 and H2S. These malodorous gases will affect and endanger the health of breeders and surrounding residents. Therefore, purification equipment is needed to purify the aquaculture wastewater. However, existing wastewater purification equipment has certain defects in actual use. Because aquaculture wastewater contains certain solid impurities such as feces, it is not convenient to separate them from the wastewater. At the same time, it cannot be collected and reused after separation. This not only affects the purification effect of the purification equipment, but also prevents the reuse of feces.
[0003] The utility model proposes a new solution to the above problems. Utility Model Content
[0004] The main purpose of the utility model is to provide a breeding wastewater purification device in order to solve the deficiencies of the existing technology.

[0024] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.
[0025] like Figures 1-6 As shown, the aquaculture wastewater purification device provided in this embodiment includes a purification tank 1, a sewage pipe 2 is connected to the bottom end of the purification tank 1, a dosing mechanism is connected to one side of the purification tank 1, a sloping plate filler 3 is installed in the middle of the purification tank 1, a first motor 4 is installed on the top of the purification tank 1, the output end of the first motor 4 is connected to the first rotating shaft 5, the bottom end of the first rotating shaft 5 is connected to the scraper 6, and the top side wall of the purification tank 1 is connected to the outlet pipe 7. Through the setting of the dosing mechanism, when in use, a flocculant such as polyferric sulfate is added, which can quickly flocculate. The wastewater enters the purification tank 1. Due to the large area of the purification tank 1, the water flow rate slows down and it will slowly rise. During this period, the flocculants in the wastewater will settle. The precipitated wastewater is discharged from the outlet pipe 7 through the sloping plate filler 3. The setting of the sloping plate filler 3 improves the sedimentation efficiency. When there is a lot of sediment, the sewage pipe 2 is opened for sewage discharge. At the same time, the first motor 4 is started to drive the scraper 6 through the first rotating shaft 5 to quickly discharge the stacked sediment. The discharged sediment can be collected and then processed for reuse.
[0026] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, the dosing mechanism includes a dosing box 8 fixedly connected to one side of the purification tank 1, a second motor 9 is installed on the top of the dosing box 8, the output end of the second motor 9 is connected to the second rotating shaft 10, and a stirring blade 11 is connected to the outer wall of the second rotating shaft 10. A water inlet 12 located below the inclined plate filler 3 is provided between the dosing box 8 and the purification tank 1, a raw water pipe 13 is connected to the side of the dosing box 8 away from the water inlet 12, and a partition 14 is connected to the middle of the dosing box 8, and the top of the partition 14 is lower than the top surface of the dosing box 8. Through the arrangement of the second motor 9, the second rotating shaft 10 and the stirring blade 11, flocculant is added while wastewater is passed from the raw water pipe 13 to the dosing box 8, and stirring and mixing can be carried out. Through the arrangement of the partition 14, the stirring and mixing time can be extended so that it can be fully mixed.
[0027] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, the bottom of the first rotating shaft 5 is connected with a spiral blade 15, and the purification tank 1 is open. The setting of the spiral blade 15 can prevent blockage and improve sewage discharge efficiency. The purification tank 1 is open, which makes it easy to observe the purified water quality.
[0028] In this embodiment, if Figure 1 、 Figure 2 and Figure 4 As shown, the inner wall of the purification tank 1 is connected to a water collecting trough 16 located above the inclined plate filler 3. The water collecting trough 16 includes an annular plate 17 connected to the inner wall of the purification tank 1. The inner ring of the annular plate 17 is connected to a side plate 18. The annular plate 17 is located below the outlet pipe 7. The top of the side plate 18 is higher than the outlet pipe 7. A plurality of water collecting ports 19 are evenly opened on the top of the side plate 18, and a filter screen 20 is installed on the water collecting port 19. Through the setting of the water collecting trough 16, the wastewater passing through the inclined plate filler 3 needs to cross the side plate 18 and enter the water collecting trough 16 before it can be discharged through the outlet pipe 7, which can further play a role in sedimentation. The setting of multiple water collecting ports 19 can make the wastewater enter the water collecting trough 16 evenly, thereby reducing the flow rate and improving the sedimentation efficiency. The filter screen 20 can perform filtering.
[0029] In this embodiment, if Figures 1-6 As shown, the working process of the aquaculture wastewater purification device provided in this embodiment is as follows:
[0030] Step 1: When in use, wastewater enters the dosing tank 8 through the raw water pipe 13, and the flocculant is introduced into the dosing tank 8 using a metering pump. The second motor 9 is started to drive the stirring blade 11 to stir the wastewater through the second rotating shaft 10, and the mixed wastewater passes through the partition 14 and enters the purification tank 1;
[0031] Step 2: The wastewater enters the purification tank 1 and slowly rises. During this period, the flocculants in the wastewater will settle. The settled wastewater will settle again through the inclined plate filler 3, and finally enter the water collection tank 16 and be discharged from the outlet pipe 7;
[0032] Step 3: When there is a lot of sediment, open the sewage pipe 2 to discharge the sewage, and at the same time start the first motor 4 to drive the scraper 6 through the first rotating shaft 5 to quickly discharge the stacked sediment.
[0033] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
