Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, in particular to a kitchen waste composting treatment system. Background Technique

[0002] Among the proportion of garbage content in our country, the content of kitchen waste is much higher than that of other countries in the world (more than 40%). At present, the annual output of kitchen waste in our country exceeds 100 million tons. Under the general trend of the continuous increase of kitchen waste and the current situation that the garbage classification policy has been implemented in various parts of the country, people's recognition and acceptance of the standardized treatment of kitchen waste are getting higher and higher. It can be foreseen that the production lines and processors for the standardized and harmless treatment of kitchen waste will become more and more standardized and gradually popularize to become the standard for garbage treatment in each city and region.

[0003] Kitchen waste contains extremely high moisture and organic matter, which is mainly composed of starch, cellulose, protein, lipids and inorganic salts, and is very easy to rot and produce a foul smell. If not properly treated and disposed of, it is very easy to harm the human living environment and population health. Kitchen waste has the following characteristics: (1) High moisture content. The moisture content of kitchen waste is about 80%, which also brings trouble to garbage collection, transportation and treatment. (2) Easy to rot. The organic matter content in kitchen waste reaches more than 95%, which is easy to produce corruption and stench, and is easy to breed germs, thus causing the spread of diseases. The derived "swill oil" is extremely easy to produce carcinogenic substances - aflatoxin, which causes serious harm to human health. (3) Abundant nutrients. In addition to containing a large amount of organic matter, kitchen waste is also rich in nitrogen, phosphorus, potassium, calcium and various trace elements. After proper treatment such as harmless composting, it can be converted into fertilizer and re-enter the biosphere to give back to garden and agricultural production. The high-concentration filter press water can also produce biogas for fuel or power generation, and the grease part can be used to prepare biofuels.

[0048] Please refer to Figures 1 to 5 , a kitchen waste composting treatment system in this embodiment, includes: a pressure filtration water tank 1, a crusher 2, a dehydrator 3, a vertical high-temperature fermentation tank 4, a primary regulation tank 5, a secondary regulation tank 6, an oil separation tank 7, a flotation tank 8, an upflow anaerobic sludge bed 9, and an integrated sewage treatment device 10.

[0049] Above the pressure filtration water tank 1, a pressure filtration conveying structure is provided. The pressure filtration conveying structure is located on one side of the crusher 2. The dehydrator 3 is located below the crusher 2. The waste outlet of the dehydrator 3 is connected to the vertical high-temperature fermentation tank 4 through a screw conveyor 31;

[0050] The water outlet of the pressure filtration water tank 1 is connected to the water inlet of the first-stage regulating tank 5 through a pipeline. A chemical dosing device is provided above the first-stage regulating tank 5. The water outlet of the first-stage regulating tank 5 is connected to the water inlet of the second-stage regulating tank 6 through a pipeline. The second-stage regulating tank 6 is used to receive the wastewater after sedimentation and separation in the first-stage regulating tank 5. The water outlet of the second-stage regulating tank 6 is connected to the water inlet of the oil separation tank 7 through a pipeline. The water outlet of the oil separation tank 7 is connected to the water inlet of the air flotation tank 8 through a pipeline. The water outlet of the air flotation tank 8 is connected to the water inlet of the upflow anaerobic sludge bed 9 through a pipeline. The water outlet of the anaerobic sludge bed is connected to the water inlet of the integrated sewage treatment equipment 10 through a pipeline.

[0051] The kitchen waste transported to the kitchen waste disposal site is directly dumped onto the pressure filtration conveying structure by unloading the vehicle and evenly covered on the pressure filtration conveying structure by manual pushing. The leachate flows into the underground pressure filtration water tank 1 and enters the sewage treatment process. A large amount of interstitial water is contained in the kitchen waste, and this water can be effectively removed through natural leaching. On the one hand, natural leaching can effectively reduce the moisture content of the kitchen waste, and on the other hand, it also reduces the pressure of subsequent manual sorting and crushing dehydration.

[0052] The kitchen waste after manual sorting is transported to the crusher 2. Crushing is a necessary pretreatment for dehydration, which can maximize the destruction of the interstitial water in the kitchen waste and achieve a better dehydration effect.

[0053] In some embodiments, the pressure filtration conveying structure includes a chain plate conveyor belt 11, and filter water holes are evenly formed in each chain plate of the chain plate conveyor belt 11. A plurality of 3-mm perforated plates are evenly arranged on the chain plate conveyor belt 11, and natural water filtration is carried out through the 3-mm perforated plates.

[0054] In some embodiments, the pressure filtration conveying structure includes a fence surrounding the edge of the chain plate conveyor belt 11, and the fence is provided with a fence opening. The pressure-filtered kitchen waste enters the next process through the fence opening. The effect of setting the fence is that more kitchen waste can be stacked on the pressure filtration conveying structure, improving the pressure filtration effect.

[0055] In some embodiments, the food waste composting treatment system further includes a slag conveying structure 12. One end of the slag conveying structure 12 is adapted to the fence opening for receiving the filtered food waste conveyed by the filter press conveying structure, and the other end of the slag conveying structure 12 extends above the feeding port of the crusher 2.

[0056] The garbage on the chain plate conveyor 11 falls into the slag conveying structure 12 through the fence opening by manual pushing and raking. Manual working areas are set on both sides of the conveyor belt of the slag conveying structure 12 to break the bags of the food waste on the conveyor belt of the material conveying structure and sort out metals, plastic bottles, disposable bowls, and other non-degradable garbage that will cause machine failures. An artificial braking switch is set on the conveyor belt of the slag conveying structure 12, and workers can stop the conveyor at any time to carry out the refinement work of garbage sorting.

[0057] Manual sorting is an essential link in food waste treatment. Since the garbage classification system in China is not yet perfect, food waste usually contains a large amount of plastics and other items, with a wide variety of types. Without manual sorting, it is easy to cause failures in the subsequent crushing and dehydration processes. Extrusion dehydration can dehydrate food waste to less than 70%, enabling food waste to better meet the moisture content requirements of composting treatment.

[0058] The fermentation temperature of vertical high-temperature fermentation can reach between 50°C and 70°C by itself, and the oxygen supply in the bin is maintained through a negative pressure fan and stirring. Through high-temperature fermentation, complete fermentation and decomposition can be achieved. The fermentation bin is equipped with a polyurethane moisture preservation layer and an oil bath temperature control layer for precise temperature control. The high-temperature aerobic microbial degradation technology is aimed at the characteristics of food waste, screening and preparing a high-temperature aerobic microbial inoculant, adding the inoculant to the degradation equipment, and rapidly decomposing food waste at high temperature, so that food waste can be effectively treated. The final product (degradate) can be further processed into organic fertilizer or directly mixed with soil for use to improve the soil. The core part of the high-temperature aerobic microbial treatment technology is the microbial strain, which can effectively treat food waste with high salt, high oil, and high acidity. When the temperature of the strain is above 60°C, it can grow and reproduce rapidly. During the growth and reproduction process, it decomposes food waste to provide nutrients for its own growth. During the treatment process, there is no need to repeatedly add or replace the strain. At the same time, the strain can still survive and play a degradation role under the condition of high temperature killing other pathogenic bacteria and parasite eggs in the garbage. Advantages of the high-temperature microbial degradation technology: The food waste treatment technology not only combines the advantages of microbial treatment technology but also overcomes the disadvantage of the need to regularly add inoculants in this technology. The treated product is a high-quality raw material for organic fertilizer, overcoming the disadvantage of poor feasibility of directly carrying out aerobic composting of food waste.

[0059] The dosing equipment adds lime to the first-stage regulating tank 5 to adjust the pH value to 7-8. After sedimentation and separation of mud and water, the wastewater enters the second-stage regulating tank 6.

[0060] The wastewater in the secondary regulating tank 6 enters the oil separation tank 7 for oil-water separation. Since the oil content in the kitchen wastewater is very high, to avoid difficulties in collection during recycling, a three-stage natural oil separation tank 7 can be set up, and an automatic oil scraping and collection device can be installed to collect and process quickly, preventing the oil from fermenting in the tank and generating organic foam.

[0061] The oil-separated wastewater enters the air flotation tank 8. The air flotation method is widely used in the biochemical pretreatment of sewage and can effectively remove oil and suspended solids. The air flotation principle is to form highly dispersed tiny bubbles in water, which adhere to the hydrophobic solid or liquid particles in the wastewater, forming a water-air-particle three-phase mixed system. After the particles adhere to the bubbles, the flocs with an apparent density less than that of water float to the water surface and form a scum layer to be scraped off, thus realizing the process of solid-liquid or liquid-liquid separation. If necessary, the removal effect can be enhanced by adding chemicals.

[0062] The water pump of the air flotation tank 8 pumps the water to the upflow anaerobic sludge bed 9 (abbreviated as UASB in English). The UASB uses a pulse water distribution tank for water distribution, and at the same time, the wastewater is recycled from the anaerobic tank to further dilute the COD in the wastewater, creating conditions for entering the UASB. The wastewater enters the main reaction zone of the anaerobic reactor. The wastewater undergoes hydrolysis acidification and partial methanation. The methane is separated and collected by a special three-phase separator and then discharged into the air at high altitude after removing toxic substances through a water seal tank. The effluent of the UASB anaerobic reactor enters the anaerobic tank by gravity flow. The anaerobic tank is filled with combined fillers and a submersible agitator is used to agitate and mix the wastewater to improve the treatment effect.

[0063] The effluent of the UASB enters the integrated sewage treatment equipment 10 for biochemical treatment.

[0064] The integrated sewage treatment equipment 10 is a general equipment in this field. The following is a brief introduction to the integrated sewage treatment equipment 10: The integrated sewage treatment equipment 10 is mainly divided into an anoxic tank, an aerobic tank, and an MBR unit. 1) Anoxic tank + aerobic tank: The sewage first enters the anoxic tank after passing through the regulating tank. The anoxic tank mainly conducts the denitrification and nitrogen removal reaction of the nitrified liquid reflux from the aerobic tank and removes part of the COD. And the reflux flow rate of the nitrified liquid is reasonably controlled. There is no aeration, and a stirring device is provided. The aerobic tank mainly conducts the nitrification reaction of NH3-N. Nitrifying bacteria include nitrite bacteria and nitrifying bacteria. Nitrite bacteria convert NH3 in the wastewater into nitrite, and nitrifying bacteria convert nitrite into nitrate, which is called nitrification. Nitrification must be completed through the combined action of these two types of bacteria. Denitrifying bacteria convert nitrate into N2, NO, and N2O, which is called denitrification. Nitrifying bacteria must act under aerobic conditions. Denitrifying bacteria must be carried out under anaerobic or anoxic conditions. The dissolved oxygen in the anoxic tank is controlled at about 0.5. Through the mud-water reflux in the aerobic tank, the wastewater continuously undergoes nitrification and denitrification to remove ammonia nitrogen; at the same time, through the phosphorus uptake and release of microorganisms, phosphorus is removed by discharging the excess sludge. Most of the COD is removed through the aerobic reaction.

[0065] 2) MBR tank: The wastewater after anoxic and aerobic treatment flows into the MBR membrane tank, and the membrane is used to filter the muddy sewage in the biochemical reaction tank to achieve mud-water separation. On the one hand, the membrane intercepts the microorganisms in the reaction tank, greatly increasing the concentration of the activated sludge in the tank to a very high level, making the biochemical reaction for degrading sewage proceed more rapidly and thoroughly. On the other hand, due to the high filtration accuracy of the membrane, it ensures that the effluent is clear and transparent, obtaining high-quality product water.

[0066] The membrane tank is provided with an MBR membrane module system and supporting systems such as effluent, backwashing, chemical cleaning, and purging. The purging (aeration) in the MBR membrane area has two purposes. One is to be used for the gas-water oscillation around the membrane module to keep the membrane surface clean, and the other is to provide the oxygen required for biodegradation. Through the efficient interception of the membrane, all bacteria and suspended solids are intercepted in the aeration tank, which can effectively intercept nitrifying bacteria, making the nitrification reaction proceed smoothly and effectively remove ammonia nitrogen; at the same time, it can intercept macromolecular organic matter that is difficult to degrade, extend its residence time in the reactor, and make it degrade to the maximum extent. The excess sludge is regularly discharged through the excess sludge pump in the membrane area, and the concentration of the activated sludge and the sludge age in the system can be controlled.

[0067] In some embodiments, water filtering holes are provided on the conveyor belt of the slag conveying structure 12. The sorting conveyor belt is also provided with water filtering holes, and the leachate flows to the ground and converges into the pressure filtration water tank 1 to enter the sewage treatment link.

[0068] In some embodiments, the number of the vertical high-temperature fermentation tanks 4 is multiple, and composting fermentation can be carried out simultaneously to improve the fermentation efficiency.

[0069] In some embodiments, the crusher 2 is a double-shaft crusher 2. The double-shaft shearing crushing is adopted by the crusher 2, so that there is no need to worry about the failure caused by some plastics and other sundries entering the crushing system.

[0070] In some embodiments, the food waste composting treatment system further includes a secondary fermentation tank 41, and the secondary fermentation tank 41 is used for secondary fermentation of the materials fermented in the vertical high-temperature fermentation tank 4.

[0071] In some embodiments, the food waste composting treatment system further includes a sludge tank 61, and the sludge tank 61 is communicated with the sewage outlet of the primary regulation tank 5 through a sewage pipe. The sludge settled in the primary regulation tank 5 will be discharged into the sludge tank 61 through a pipeline.

[0072] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of the present application, the patent protection scope of the present application cannot be limited thereby. Any equivalent structure or equivalent process substitution or modification generated by using the content recorded in the text and drawings of the specification of the present application based on the essential concept of the present application, as well as the technical solutions of the above embodiments directly or indirectly implemented in other related technical fields, etc., are all included in the patent protection scope of the present application.
