Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, in particular to a biological degradation treatment device for high-oil wastewater in pre-prepared food processing. BACKGROUND

[0002] Pre-prepared food, also known as pre-prepared dishes, is a pre-packaged dish prepared by industrialized pre-processing using one or more edible agricultural products and their products as raw materials, with or without auxiliary materials such as seasonings, and in accordance with the storage, transportation and sales conditions indicated on the product label, and can only be eaten after heating or cooking. In the production and processing process of pre-prepared food, a large amount of wastewater containing a large amount of oil is generated, which needs to be treated before being discharged.

[0003] The oil wastewater is biodegraded by microorganisms. Generally, this method requires the separation of waste oil first, and then the mixing of specific bacteria liquid and kitchen waste oil liquid, and the digestion and decomposition of waste oil by the activity of microorganisms. For example, Chinese patent CN220078811U discloses a waste oil biodegradation equipment. The waste water and oil need to be separated in advance, and the separated oil and wastewater also need to be treated, i.e. two sets of treatment equipment are needed, which will double the treatment cost and process. Therefore, in order to reduce the treatment cost, the joint treatment of oil and wastewater is more in line with the requirement of reducing cost. For example, Chinese patent CN214880985U discloses an efficient biological treatment system for domestic sewage, which carries out multi-stage degradation treatment of oil and wastewater through multiple degradation tanks.

[0004] However, due to the fact that the density of oil is less than that of water, the oil floats on the top of the wastewater to form a thick oil layer. At the same time, microorganisms need to secrete lipase to degrade oil, such as Acinetobacter, Pseudomonas and fungi, which are good at secreting lipase to decompose oil. Since the oil wastewater contains not only waste oil but also organic matter that is more easily absorbed by microorganisms, the microorganisms need to secrete lipase first before they can absorb the waste oil. Therefore, the microorganisms are not inclined to decompose the waste oil, which affects the degradation treatment efficiency of the waste oil. SUMMARY

[0006] The core of the present application is to introduce microorganisms into the oil layer by combining the culture module with the oil layer floating, so as to solve the problem of low degradation treatment efficiency of waste oil in the prior art.

[0039] When the high-grease wastewater is treated, the high-grease wastewater is first sent into the grease degradation tank 102 through the wastewater input pipe 201 to be subjected to sedimentation and oil separation, the stratification of grease and wastewater is realized by using the difference in oil-water density, the grease is concentrated in the grease degradation tank 102, the microorganisms good at degrading grease are concentrated in the grease, and the degradation efficiency of grease in the grease degradation tank 102 is effectively improved, and after the on-off valve 106 of the upper sedimentation hopper 104 is opened, the organic wastewater deposited at the bottom of the grease degradation tank 102 falls into the lower sedimentation hopper 105, and then slowly enters the sedimentation degradation tank 101 through the flow-limiting mesh plate 107, so that the influence on the sedimentation state in the sedimentation degradation tank 101 is effectively reduced.

[0040] Please refer to Figures 3 to 7The inner end of the wastewater input pipe 201 extends vertically into the grease degradation tank 102, and the outer part of the wastewater input pipe 201 is sleeved with the culture module 3. The bottom of the culture module 3 is fixedly connected with the buoyancy module 4. The culture module 3 floats above the liquid surface of the wastewater through the buoyancy module 4, so that the culture module 3 is combined with the grease layer. The culture module 3 is composed of a plurality of stacked culture medium films 301. The surface of the culture medium film 301 is uniformly provided with through holes 302. The plurality of distributed culture medium films 301 separate and divide the grease layer, facilitate the reproduction and growth of microorganisms in the grease layer, so that the lipase produced by the microorganisms is mixed with the grease, and the degradation efficiency of the grease is effectively improved. The adjacent two culture medium films 301 are uniformly fixedly connected with floating balls 303. The floating ball 303 is hollow inside. The outer diameter of the floating ball 303 is sequentially reduced from top to bottom according to the position. The floating ball 303 is made of elastic rubber material. The culture medium film 301 enhances its floating ability through the floating ball 303. The diameter of the floating ball 303 makes the buoyancy of the uppermost culture medium film 301 greater than that of the lowermost culture medium film 301, so that the culture medium film 301 is laid from top to bottom. The inside of the buoyancy module 4 is provided with uniformly distributed air chambers. The buoyancy module 4 enhances its buoyancy through the air chambers. The culture medium film 301 and the buoyancy module 4 are both made of polypropylene material. The density of the polypropylene material is between the density of grease and the density of water, so that the culture medium film 301 can float in the grease layer. The bottom of the tank cover 2 is fixedly connected with a blocking baffle 202. The top end surface of the culture module 3 abuts against the bottom end surface of the blocking baffle 202. When the amount of wastewater in the grease degradation tank 102 increases, the liquid surface of the wastewater rises. The top of the culture module 3 abuts against the blocking baffle 202, and the buoyancy module 4 continues to rise, so as to extrude the culture module 3 and discharge the grease and grease degradation products in the culture module 3. After the wastewater in the grease degradation tank 102 is discharged into the sink hopper 105, the liquid surface of the wastewater in the grease degradation tank 102 decreases, the culture module 3 absorbs grease again, the grease in the culture module 3 is rearranged, and the degradation effect of the grease is effectively improved.

[0041] When the oil is degraded by microorganisms in the oil degradation tank 102, the oil and wastewater in the oil degradation tank 102 are stratified due to the difference in density. The culture module 3 is floated above the liquid surface of the wastewater by the buoyancy module 4, so that the culture module 3 is combined with the oil layer. The multilayer distributed culture medium film 301 separates and divides the oil layer, which facilitates the reproduction and growth of microorganisms in the oil layer, so that the lipase produced by the microorganisms is mixed with the oil, and the degradation efficiency of the oil is effectively improved. After new oil wastewater is sent into the oil degradation tank 102, the liquid surface of the wastewater in the oil degradation tank 102 rises, the top of the culture module 3 is in contact with the blocking baffle 202, the buoyancy module 4 continues to rise to extrude the culture module 3, so as to extrude the oil in the culture module 3 and discharge the oil degradation products in the culture module 3. Subsequently, the wastewater in the oil degradation tank 102 is discharged downward, the liquid surface of the wastewater is lowered, the culture module 3 absorbs the oil again, the oil in the culture module 3 is rearranged, and the degradation effect of the oil is effectively improved.

[0042] Embodiment

[0043] Compared with Embodiment 1, the main addition is the water injection pipe 5. The specific added structure is as follows, and the remaining structure is the same as that of Embodiment 1.

[0044] Please refer to Figures 7 to 9 The bottom end of the oil degradation tank 102 is fixedly connected with the water injection pipe 5. The water injection pipe 5 is used to send clean water into the oil degradation tank 102, so as to raise the liquid surface of the wastewater in the oil degradation tank 102, and the same effect of rearranging the oil in the culture module 3 in Embodiment 1 is achieved. The water injection pipe 5 is externally provided with an input pump 501. The input pump 501 effectively improves the water pressure of the clean water, so as to facilitate the rise of the liquid surface of the wastewater in the oil degradation tank 102. The lower surface of the buoyancy module 4 is fixedly connected with a driving plate 401 in a ring shape. The inner end of the water injection pipe 5 faces the driving plate 401, and the water injection pipe 5 is eccentrically arranged with the axis of the oil degradation tank 102. When the water injection pipe 5 sends clean water into the oil degradation tank 102, the water impacts the driving plate 401, so as to rotate the culture module 3 driven by the buoyancy module 4, further disturb the oil distribution of the culture module 3, and effectively improve the degradation efficiency of the oil;

[0045] When no new oil wastewater is sent into the oil degradation tank 102 for a long time, the clean water injection pipe 5 is used to send clean water into the oil degradation tank 102. The sent clean water first impacts the driving plate 401, so that the buoyancy module 4 drives the culture module 3 to rotate, disturbs the oil distribution of the culture module 3, and until the driving plate 401 rises out of the clean water impact range of the clean water injection pipe 5. The buoyancy module 4 will still rotate for a period of time due to inertial force. The clean water and the wastewater are mixed, the organic matter concentration of the wastewater is diluted, the influence of high-concentration wastewater on the growth and reproduction of microorganisms is effectively reduced, the wastewater level in the oil degradation tank 102 is raised, the oil in the culture module 3 is rearranged, and the oil degradation efficiency is effectively improved.

[0046] Please refer to Figures 7 to 11 The connection part of the buoyancy module 4 and the driving plate 401 is uniformly provided with an upper infiltration port 402. The upper infiltration port 402 communicates the upper and lower surfaces of the buoyancy module 4. When the clean water impacts the driving plate 401, the driving plate 401 guides the rising wastewater to enter the culture module 3 through the upper infiltration port 402, so that the oil degradation product is dissolved in water, the cleaning efficiency of the oil degradation product is effectively improved, the oil is easily reabsorbed into the culture module 3, and the upper end of the extension pipe 403 is fixedly connected with the uppermost culture medium film 301. The extension pipe 403 is inserted into the through hole 302, and the outer surface of the extension pipe 403 is uniformly provided with an infiltration hole 404. The extension pipe 403 is made of elastic rubber material, and is used to support the uppermost culture medium film 301, so that the multi-layer culture medium film 301 is easily unfolded, and the infiltration holes 404 on the extension pipe 403 are used to uniformly distribute the wastewater between each layer of culture medium film 301.

[0047] By providing the upper infiltration port 402, when the wastewater level rises, the rising wastewater enters the culture module 3 through the upper infiltration port 402, so that the oil degradation product is dissolved in water, the cleaning efficiency of the oil degradation product is effectively improved, the oil is easily reabsorbed into the culture module 3, the extension pipe 403 supports the uppermost culture medium film 301, so that the multi-layer culture medium film 301 is easily unfolded, and the infiltration holes 404 on the extension pipe 403 are used to uniformly distribute the wastewater between each layer of culture medium film 301.

[0048] Compared with the embodiment 1, in this embodiment, when no new oil wastewater is fed into the oil degradation tank 102 for a long time, the clean water can be fed into the oil degradation tank 102 through the clean water feeding pipe 5. The fed clean water first impacts the driving plate 401, so that the buoyancy module 4 drives the culture module 3 to rotate, disturbs the oil distribution of the culture module 3, and with the increase of the water amount in the oil degradation tank 102, the wastewater level in the oil degradation tank 102 rises, the same as the oil rearrangement function of the culture module 3 in the embodiment 1, and the rising wastewater enters the culture module 3 through the upward infiltration port 402, so that the oil degradation products are dissolved in water, effectively improving the cleaning efficiency of the oil degradation products, and further effectively improving the oil degradation efficiency.

[0049] The above description is only the preferred embodiment of the present application; any person skilled in the art should be covered within the protection scope of the present application according to the technical solution and the improved concept of the present application, and any equivalent replacement or change should be covered within the protection scope of the present application.
