Description

Breed waste disposal system

Technical Field

The utility model relates to a water treatment field, in particular to breed waste treatment system.

Background

In the past, the manure of livestock and poultry is stored in a pit for a long time and is fermented to be used as agricultural fertilizer such as liquid manure, but in recent years, the original mode cannot be applied along with the large-scale development of agriculture. Legislation dictates and strengthens the handling of the various fecaluria occurring in poultry and livestock that must be conducted through the treatment facilities. Thus, although farmers invest a large amount of treatment facilities, the offensive odor of excrement and urine generated during treatment is another problem.

Accordingly, a method for promoting the reclamation of the livestock manure by utilizing the natural purification effect of the soil has been proposed. Organic matter such as remains of animals and plants and excrement is denatured in soil into inorganic matter and soil humus. In this case, it is the soil microbial population that plays a decisive role in the reaction, and the microbial population prevents the organic matter from putrefaction by making the organic matter into a low molecular weight state through a humification reaction, thereby preventing the occurrence of offensive odor.

However, the technology (RBS technology) using the natural cleaning method has not been widely used as a standard in China. Most farmers are still wantonly released or depend on anaerobic fermentation technology which has low efficiency and causes secondary environmental pollution.

The utility model provides a breed waste treatment method can also include: subjecting the first pass stream to a primary humification treatment to provide a third pass stream. The humification treatment generally refers to a process in which substances to be treated form humins under the action of microorganisms through biochemical and chemical actions. The concentration of various microorganisms (such as Bacillus sp, Pseudomonas sp, Micrococcus sp, Flavoba-ctrium sp, Bacullussphaericus, Bacillus megaterium, Cladosporium, Penicillium, Tricoderma, Stachybotris, etc.) in the humification treatment can be generally more than or equal to 5000ppm, and the primary humification treatment is generally carried out in a high MLSS (mixed liquor suspended solids concentration) state, such as MLSS (mixed liquor suspended solids concentration) more than or equal to 3000mg/L, more than or equal to 4000mg/L, or more than or equal to 5000mg/L, so that the propagation density of nitrifying bacteria with longer sludge age and slower propagation speed can be improved, and the sludge capacity needs to be paid attention to, but the sludge is generally not suitable to be excessive during the primary humification treatment, and whether the sludge excess is the prior art or not can be judged, such as DO is generally less than or equal to 0.7ppm, ORP is generally more than or equal to 100 ppm, so that the sludge excess can be prevented. In the primary humification treatment, the first passing stream can carry out certain humification reaction, the primary humification treatment is usually carried out under anaerobic conditions, after the primary humification treatment, water-soluble organic matters in the first passing stream are coagulated, condensed, polymerized, superposed and polycondensed until the water-soluble organic matters are converted into sludge, liquid is removed in the process, meanwhile, particle substances which can form stink and are dissolved in the wastewater are also removed, the humification reaction is started, and the BOD content in the fluid can be further reduced. In the treatment process of the whole cultivation waste treatment method, the introduction amount of raw water (for example, waste) is not necessarily constant, so the amount of the first pass stream obtained after solid-liquid separation is also not necessarily constant. Therefore, when the first pass stream is subjected to primary humification treatment, the amount and concentration of the stream can be equalized by a device (for example, a mixing device) used by the first pass stream, and then the first pass stream is conveyed to a subsequent device and subjected to subsequent treatment, so that the amount of the stream in the subsequent treatment process is maintained in a basically quantitative state.

The secondary humification treatment can be carried out under aerobic conditions, and those skilled in the art can select a suitable method to maintain the oxygen content in the reaction system, for example, aeration can be adopted, and physical external force is usually avoided as much as possible during the supplement process, so that the external force can be prevented from damaging the sludge, for example, the aeration rate can be maintained at 0.03m³air/min.m³～0.04m³air/min.m³Under the conditions of (a). In the secondary humification treatment process, in order to enlarge the denitrification effect, according to the flow direction of the fluid in the reaction system, the fluid which is relatively positioned in the reaction system can be returned to the position which is relatively positioned in front of the reaction system, for example, the sludge at the rear end can be returned to the front end and/or the middle, and the returned amount can reach 80-200%, 80-120%, 120-160%, 160-200%, 200-250%, 250-300%, 300-400%, 400-500%, 500-600% of the introduction amount of the stream strand in the humification treatment, or600-800%, so that the breeding density of the nitrate bacteria with a slow breeding speed is improved in the humification process, the nitrate bacteria contained in the cultured sludge are supplied to the humification treatment, the efficiency of the breeding of the nitrate bacteria is higher than that of the breeding of the nitrate bacteria naturally occurring in the humification treatment, and for example, the time of the two humification treatments can be 20-35 days, 20-25 days, 25-30 days or 30-35 days on the whole, so that the time is greatly shortened compared with the time in the prior art. In the secondary humification treatment, the third through-flow strand which has undergone certain humification pre-reaction can further undergo humification reaction, enough oxygen content can enable substances such as BOD, SS, T-N, T-P and the like in the third through-flow strand to be rapidly decomposed, BOD and COD are reduced by 60-80% compared with raw water, the nitrification proportion in the humification treatment process can exceed 98%, BOD and COD in waste which firstly flows into a reaction system can be used as carbon sources in the whole treatment process, aerobic microorganisms and facultative anaerobes can be breathed, sludge returned from the humification treatment flow point and oxygen in Nox molecules in sludge returned from the humification rear end, and denitrification can be promoted while BOD and COD values are reduced. The fourth pass stream obtained is typically a mixture of the stream and 53 microbial sludge and can be further treated to provide liquid fertilizer and sludge.

The utility model provides a breed waste treatment method can also include: and carrying out precipitation treatment on the fourth through-flow strand to provide a liquid fertilizer and sludge stream. The precipitation treatment is generally a treatment method in which an object (for example, a product or an impurity) in a fluid is precipitated as an amorphous solid phase and then separated. In the sedimentation treatment, because the DO of the fluid is low, nitrogen in the fluid can be further removed in the treatment process, and BOD and COD can be reduced along with the removal of T-N. In the precipitation treatment, the hydraulic retention time may be specifically not less than 8 hours, not less than 12 hours, not less than 16 hours, or not less than 20 hours.

The utility model provides a breed waste treatment method can also include: subjecting the second pass stream to aerobic fermentation treatment to provide a fifth pass stream. The aerobic fermentation treatment generally refers to a treatment method for decomposing organic matter in a stream by the action of a microorganism (for example, the microorganism may be Bacillus sp, Pseudomonas sp, Micrococus sp, Flavoba-cterum sp, Bacillus sphaericus, Bacillus megaterium, clausporium, Penicillium, Tricoderma, Stachybotris, etc.) in the presence of an active silicate and/or a catalytic humus. The second pass stream, which typically includes organic solids water-resistant granular structures, has some soil particles agglomerated together even in water, not dispersed into a structure of individual particles. In the aerobic fermentation treatment, the active silicate catalyst can generally play a role in promoting humification reaction, and can react with catalytic humus to generate a chelating combination of a microbial metabolite, an organic decomposition product and a resynthesis productSubstances such as substances and adhesive substances which are aggregated, condensed, agglomerated, and polycondensed, and which are capable of removing organic substances in an aqueous organic-aqueous solution in a liquid state with an increase in molecular weight, and treated water or sludge not only has a strong chelate structure but also is generally excellent in mold and deodorizing functions as metabolites of these microorganisms. In the aerobic fermentation treatment, it is also possible to introduce catalytically humic substances of microbial activity (for example, peat humates and the like) which have been cultured in the course of repeated liquid cycles, and therefore it is not necessary to carry out the separate external addition of humic substances, but it is of course advantageous if the addition can be carried out at a ratio of about 1/1000 in the inoculation stage. In the aerobic fermentation treatment, the reaction is usually carried out under aerobic conditions, for example, the oxygen concentration in the reaction environment can be more than or equal to 40%, and for example, the oxygen concentration in the reaction environment can be 50-150L/min³. In the aerobic fermentation treatment, the reaction is preferably carried out at a high temperature of 60-80 ℃, 60-65 ℃, 65-70 ℃, 70-75 ℃ or 75-80 ℃, an external heat source is not required to heat the reaction process, the reaction temperature can be controlled by stirring, the temperature is increased due to the metabolic activity of microorganisms during the overturning and stirring, and the reaction temperature is not increased to more than 90 ℃, namely, the reaction temperature is required to be less than or equal to 90 ℃. The reaction time of the aerobic fermentation treatment is 10 to 45 days, 10 to 15 days, 15 to 20 days, 20 to 25 days, 25 to 30 days, 30 to 35 days, 35 to 40 days, or 40 to 45 days. The suitable water content of the second passing stream for effectively inducing the aerobic fermentation treatment is at least 60-75%, in order to prevent the fermentation efficiency from being low due to the fact that high-temperature aerobic fermentation (60-80 ℃) in the reaction system can cause a large amount of water evaporation during the aerobic fermentation treatment, a proper amount of culture sludge liquid can be introduced, and the culture sludge liquid can be from culture treatment or precipitation treatment. The method for introducing the culture sludge liquid may be spraying water onto the reaction system, or may be returning a part of the leach water (water flowing out of the reaction system) generated in the aerobic fermentation treatment as raw water for liquid manure treatment, or may be returning a part of the leach water for preventing secondary pollutionIs used for adjusting the temperature and the moisture of the reaction system. The height of the fermentation layer in the aerobic fermentation treatment can be 2-3 m, 2-2.5 m or 2.5-3 m, and the treatment efficiency can be further improved. In the fifth passing stream obtained by the aerobic fermentation treatment, based on the mass of the whole passing stream, the content of organic matters can be 30-45%, 30-35%, 35-40%, or 40-45 wt%, the content of water can be 40-55 wt%, 40-45 wt%, 45-50 wt%, or 50-55 wt%, the content of nitrogen can be 0.8-1.2 wt%, 0.8-0.9 wt%, 0.9-1.0 wt%, 1.0-1.1 wt%, or 1.1-1.2 wt%, the content of phosphorus can be 1-3 wt%, and the content of potassium can be 1-2 wt%.

The utility model provides a breed waste treatment method can also include: adjusting the water content of the second pass stream to 60-75 wt% to provide a water content adjusted second pass stream. When the water content of the second pass stream is below 60%, the decomposition rate is reduced, and when the water content of the second pass stream is above 75%, the oxygen diffusion phenomenon does not occur, and the odor generation or the fertilizer fixation efficiency is reduced under the action of anaerobic organisms. Methods of adjusting the moisture content should be known to those skilled in the art, for example, sawdust (e.g., sawdust with a C/N ratio below 25), methods of returning a fifth pass stream, e.g., at least a portion of the fifth pass stream may be used to mix with the second pass stream, which may typically have a moisture content of 20-50 wt%, has been generated by metabolic activity of microorganisms into a large amount of various metabolites beneficial to soil and plants and beneficial active microorganisms, and a portion of which (typically 30-50 wt% of the fifth pass stream) may be mixed with the newly inflowing second stream, which may serve to adjust the moisture content and promote fermentation activity.

The utility model provides a breed waste treatment method can also include: and carrying out after-ripening fermentation treatment on at least part of the fifth through strands to provide solid fertilizer. In the after-ripening fermentation treatment, after the decomposition by the action of high-temperature microorganisms, most of the organic matters which can be decomposed are decomposed, so that the decomposition speed is obviously slowed down, the temperature of the solid fertilizer is reduced to 30-40 ℃, and the water content is reduced to below 55%. The method of subjecting the fifth stream to an after-ripening fermentation treatment should be known to those skilled in the art, for example, the time of the after-ripening fermentation treatment may be about 30 days, 20 to 40 days, 25 to 35 days, or 28 to 32 days. In the process of after-ripening fermentation treatment, the mesophilic microorganisms enter a re-stabilization stage, and have slight difference from the species and density of microorganisms in the initial stage, because a considerable part of organic matters in the ripening stage are changed into humus (humus) which is difficult to decompose again, so that the treated matters until after-ripening fermentation can be used as organic solid fertilizers per se or mixed with other fermented cow dung, chicken manure and the like to produce organic compound fertilizers. The main functions of the solid fertilizer include improving physical properties of soil, improving chemical properties of soil, improving biological properties of soil, completely decomposing harmful substances, promoting growth of substances, preventing continuous cropping obstacles, and the like, wherein the content of plant hormones such as nitrogen is 0.8-1.2 wt%, 0.8-0.9 wt%, 0.9-1.0 wt%, 1.0-1.1 wt%, or 1.1-1.2 wt%, the content of phosphorus is 1-3 wt%, 1-1.5 wt%, 1.5-2 wt%, 2-2.5 wt%, or 2.5-3 wt%, the content of potassium is 1-2 wt%, the content of water is 60 wt% or less, 55 wt% or less, 50 wt% or less, or 45 wt%, the content of organic substances is 35 wt% or more, 40 wt% or more, or 45 wt%, and the C/N ratio is 45 wt% or less, Less than 40 or less than 35, the degree of decomposition may be 3.5 or more, 4 or more, or 4.5 or more, and the pH may be weak alkaline, specifically 7.5 to 8.5, 7.5 to 7.7, 7.7 to 7.9, 7.9 to 8.1, 8.1 to 8.3, or 8.3 to 8.5.

The lower end is kept in an aerobic condition by an air device and a calandria, and is sufficiently stirred by a screw stirrer. The basic condition of aerobic fermentation is that air is injected into the lower end of the piled solid and stirring is started, and the metabolism temperature of the microorganism, namely the fermentation temperature of the waste, reaches above 50 ℃ at the lowest after the microorganism is activated. The method comprises the steps of performing medium-temperature fermentation for 5-10 days at the temperature of 45 ℃ above in the initial stage, performing medium-temperature fermentation for 2-7 days within the range of 60-85 ℃ in the middle stage, performing after-ripening fermentation for 17-27 days below 50 ℃ in the later stage, gradually reducing the activity of microorganisms after the high-temperature fermentation is finished, and gradually reducing the temperature and maintaining the temperature between 35-45 ℃, so that the microorganisms are gradually transformed into spore state. After the aerobic fermentation device is subjected to a fermentation period of 30 days, and then is subjected to an after-ripening process of an after-ripening fermentation device for 30 days, and finally the high-quality solid fertilizer is obtained. The color, taste, appearance, moisture content and the like of the solid fertilizer are usually measured mainly based on the C/N ratio, and the state of complete decomposition can be judged when the C/N ratio is generally 25% or less. The content of the solid fertilizer is as follows: 1.02% of nitrogen, 1.6% of phosphoric acid, 1.8% of potassium, less than 48% of water, more than 42% of organic matters, less than 25% of C/N ratio, more than 5.2 of maturity and 8.3 of PH.
