Description

TECHNICAL FIELD

[0002] Wastewater treatment is a series of physical, chemical and biological processes to reduce or remove pollutants in generated wastewater, so that it meets the standards for safe discharge or recycling. Wastewater treatment aims to protect the environment, protect human health, and promote sustainable development;

[0003] When wastewater is treated, different wastewater treatment methods are used according to the different pollutants in the wastewater. When wastewater discharged by cities and industries is treated, biochemical treatment is usually used to treat wastewater. Biochemical treatment converts harmful substances in wastewater into harmless substances by using methods that degrade organic matter, which can reduce the concentration of organic matter and pollutants and reduce the impact on the environment.

[0004] During the biochemical treatment of wastewater, it is found that during wastewater treatment, wastewater needs to be mixed with activated sludge to make microorganisms in activated sludge contact with wastewater. After wastewater and sludge are mixed, in order to improve the degradation effect of microorganisms on wastewater, metabolic degradation promoters are added to the mixture of activated sludge and wastewater. Since the mixture of activated sludge and wastewater has poor fluidity, the metabolic promoters are difficult to fully and uniformly play their role after being added, which is not conducive to improving the efficiency of wastewater treatment equipment in treating wastewater.

[0043] Embodiment two

[0044] As shown in the above embodiment, the embodiment further comprises the following contents: Figures 1-8

[0045] In order to better metabolically degrade the wastewater, the floating matter and the precipitate in the wastewater need to be removed. Therefore, the embodiment comprises the following design:

[0046] The separating mechanism 1 comprises a separating box 11, a water inlet pipe 12, a lower discharge pipe 13, a mounting disc 14 and a water blocking rod 15. The middle of one side of the separating box 11 is provided with the water inlet pipe 12. The bottom of the separating box 11 is in an inclined structure. The side of the bottom of the separating box 11 is provided with the lower discharge pipe 13.

The inside of the mounting disc 14 is provided with the water blocking rod 15 which is arrayed and distributed in multiple numbers on the inside of the mounting disc 14. The water blocking rod 15 and the water inlet pipe 12 are in a same horizontal line. Through the water blocking plate arranged in the inside of the separating box 11, the wastewater can be blocked when the wastewater enters the inside of the separating box 11, so that the flowing effect of the wastewater is reduced, and the fixed precipitate and the floating matter in the wastewater are separated from the wastewater. The rotary connection of the mounting disc 14 and the separating box 11 can change the angle of the multiple water blocking rods 15, so as to change the blocking effect of the wastewater. The lower discharge pipe 13 can discharge the precipitate which is precipitated at the bottom of the separating box 11.

[0047] ​In this embodiment, the top of the separation box 11 is provided with a collecting plate 16, which is inclined upward.

[0048] As an improvement to the above solution, the bottom of the separation tank 11 is provided with baffles 111, and multiple baffles 111 are evenly distributed. The baffles 111 distributed at equal intervals at the bottom of the separation tank 11 can block the flow of wastewater when the pump 22 draws wastewater from the inside of the separation tank 11 through the pumping pipe 221, thereby reducing the situation where the pump 22 draws wastewater sediment.

[0049] Example 3

[0050] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0051] To ensure that the wastewater is cleaner after metabolic degradation, it is necessary to guarantee that the discharged wastewater does not carry microorganisms or other impurities. Therefore, this embodiment provides the following technical solution:

[0052] The purification mechanism 3 includes a purification box 31, a drain pipe 32, and a slag discharge pipe 33. The bottom of the purification box 31 is provided with a drain pipe 32, and the side of the purification box 31 is provided with a slag discharge pipe 33.

The water supply pipe 62 is vortex-shaped, with one end inside the purification box 31 and the other end connected to the drain pipe. The vortex-shaped water supply pipe 62 can lengthen the flow of wastewater, making it easier for the heating pipe 63 to heat and disinfect the wastewater inside the water supply pipe 62.

[0053] In the embodiment, the purification assembly 7 comprises a driving roller 71, a purification filter screen 72, a first partition plate 73 and a second partition plate 74, the driving roller 71 is arranged inside the purification box 31, the driving roller 71 is rotationally connected with the purification box 31, the purification filter screen 72 is arranged outside the driving roller 71, the purification filter screen 72 is in an elastic structure, the first partition plate 73 is arranged on the top surface and the bottom surface of one end of the purification filter screen 72, the second partition plate 74 is arranged on the bottom of the other end of the purification filter screen 72, and the purification filter screen 72 is slidingly connected with the first partition plate 73 and the second partition plate 74; the driving roller 71 is arranged to drive the purification filter screen 72 to rotate; the rotation of the driving roller 71 and the purification box 31 is realized by a motor; the purification filter screen 72 is arranged to filter and remove impurities from the sterilized wastewater, and remove impurities in the wastewater.

[0054] As an improvement of the above scheme, a residue storage area is formed between the second partition plate 74 and the purification box 31, a first scraping strip 75 is arranged on one side of the top end of the second partition plate 74, the first scraping strip 75 is in an elastic structure, the first scraping strip 75 is slidingly connected with the purification filter screen 72, a supporting strip 76 is arranged above the residue storage area, the end of the supporting strip 76 is connected with the inner side of the purification box 31, a second scraping strip 77 is arranged on the end of the supporting strip 76, and the second scraping strip 77 is slidingly connected with the purification filter screen 72; when the purification filter screen 72 rotates, the first scraping strip 75 arranged on the top of the second partition plate 74 and the second scraping strip 77 arranged on the end of the supporting strip 76 can collect impurities on the surface of the purification filter screen 72 into the residue storage area, so that the wastewater filtering and purifying effect can be maintained when the purification filter screen 72 is used for a long time.

[0055] Working principle and use process of the application:

[0056] When in use:

[0057] Firstly, the wastewater to be treated is sent into the separation tank 11 through the water inlet pipe 12 of the separation tank 11, the wastewater entering the separation tank 11 contacts the water blocking rods 15 arranged in an array in the mounting disc 14, so that the wastewater is more dispersed when entering the separation tank 11, so as to separate the wastewater into layers of floating objects, precipitates and wastewater;

[0058] When the wastewater enters the separation tank 11 for nickel coin precipitation separation, the floating objects are gathered below the material collecting plate 16 at the top of the separation tank 11, and when the water level of the wastewater reaches a certain degree, the separated floating objects in the wastewater are gathered by the inclined material collecting plate 16, and the gathered floating objects overflow from the discharge port 161, so that the floating objects in the wastewater can be collected above the material collecting plate 16, and the floating objects in the wastewater can be discharged from the discharge pipe 17;

[0059] Then, the precipitate in the wastewater will gather at the bottom of the separation tank 11, and when the precipitate needs to be discharged, it can be discharged through the lower discharge pipe 13 under the action of the inclination of the bottom of the separation tank 11. When the precipitate is discharged, the feeding rod 18 is driven to rotate at the bottom of the separation tank 11 by the motor, and the spiral feeding plate 19 arranged on the outer side of the feeding rod 18 can push the precipitate downward. In this way, the precipitate in the separation tank 11 can be fully discharged.

[0060] When the wastewater is treated:

[0061] The liquid suction pump 22 on one side of the treatment tank 21 sucks the clarified wastewater in the separation tank 11 through the liquid suction pipe 221 and sends the wastewater into the treatment tank 21 through the liquid supply pipe 222. At this time, the addition tank sends the metabolic promoter (such as organic matter, oxidant, etc.) into the liquid supply pipe 222, and the metabolic promoter will enter the treatment tank 21 together with the wastewater and contact with the activated sludge in the treatment tank 21. At this time, the air supply pump 24 at the bottom of the treatment tank 21 sends air into the treatment tank 21 through the air supply pipe 241. The air flowing into the treatment tank 21 flows upward, which can increase the oxygen of the activated sludge and assist the wastewater and the metabolic promoter to mix with the activated sludge. Then, the mixing rod 51 in the mixing mechanism 5 rotates under the drive of the motor. The uniform material rod 55 and the uniform material plate 56 with arc structure at the bottom of the mixing rod 51 can horizontally stir the wastewater and the metabolic promoter discharged from the liquid supply pipe 222, and at the same time, the mixing plate 53 with spiral shape on the outer side of the mixing rod 51 can drive the wastewater and the activated sludge to flow upward together, which can fully mix the wastewater and the metabolic promoter with the activated sludge together with the cooperation of the mixing edge rod 54 on the outer side of the mixing plate 53. In this way, the microorganisms in the activated sludge can fully and uniformly metabolize and degrade the wastewater;

[0062] After the metabolism is completed:

[0063] When the wastewater is metabolized and degraded in the treatment tank 21, the mixing mechanism 5 stops mixing, and the wastewater and the activated sludge are separated by sedimentation. Then, the mounting frame 41 in the liquid guide mechanism 4 drives the guide pipe 42 to descend through the drive wheel 411 driven by the motor. The continuously descending guide pipe 42 can suck up the treated wastewater in the treatment tank 21 under the action of the liquid guide pump 44. At this time, the wastewater will enter the water supply pipe 62 of the purification assembly 7 through the guide pipe 42, the liquid guide hose 43, the liquid guide pump 44, and the liquid outlet pipe 45.

[0064] Then, the wastewater will flow in the water supply pipe 62 and finally enter the purification tank 31. In the process of flowing, the heating pipe 63 in the blocking box 61 heats and disinfects the wastewater in the water supply pipe 62. The disinfected wastewater will fall on the purification filter screen 72 in the purification tank 31. After being filtered by the purification filter screen 72, the treated wastewater will be discharged through the drain pipe 32.

[0065] Then, during the purification process, the drive roller 71 drives the purification filter screen 72 to rotate, so that the outer side of the purification filter screen 72 continuously slides in contact with the first scraping strip 75 and the second scraping strip 77. In this way, while maintaining the filtration and purification of the wastewater by the purification filter screen 72, the impurities filtered out from the surface of the purification filter screen 72 can be collected in the residue storage area, so as to maintain the purification and filtration effect of the purification filter screen 72. The filtered impurities in the residue storage area are finally discharged by the residue discharge pipe 33.
