Technical Field
The utility model relates to an agricultural waste composting device, in particular to an aerobic composting chamber.
Background
Sludge treatment background technology:
the sludge treatment mode comprises reduction and stabilization, and the disposal mode comprises harmless and recycling. Wherein the reduction includes two aspects of total reduction and volume reduction, the total reduction includes in-situ sludge reduction technology, ex-situ sludge reduction technology and the like, and the volume reduction includes sludge dewatering technology, sludge concentration technology and the like. Stabilization includes anaerobic fermentation, aerobic digestion, lime stabilization, desiccation, and the like. Harmless treatment includes sanitary landfill, land utilization, incineration and the like. The recycling includes building material utilization and the like.
The in-situ sludge reduction technique refers to: the process for reducing the total amount of sludge in the sewage treatment process mainly comprises four sludge reduction technologies of lysis-invisible growth, uncoupling metabolism, endogenous metabolism, microorganism predation and the like.
The lysis-stealth growth technique refers to: after the microbial cells subside, intracellular substances (carbon-containing organic matters and nutrient substances) are released into the system through lysis, one part of the substances are recycled by the growth of living cells, and the other part of the substances are released as respiratory metabolites, so that the sludge reduction process is realized.
Uncoupled metabolic technology refers to: on the basis of not affecting the pollutant removal effect in the sewage, the energy for cell synthesis is reduced through decoupling, and the sludge yield is reduced.
Endogenous metabolic technology refers to: when the exogenous matrix is deficient, the microorganism oxidizes and degrades the endogenous matrix to provide energy required by the cells to maintain the life activity of the cells, and the part of energy is not used for cell synthesis, and the state of consuming energy to maintain survival without synthesizing the cells when the exogenous matrix is deficient is called endogenous metabolism.
The microbial predation technique refers to: predating the bacteria in the suspension with protozoa and metazoan results in energy loss in the food chain, thereby achieving a reduction in sludge yield.
The ectopic sludge reduction technology refers to: excess sludge produced in the sewage treatment system is concentrated in a specific sludge treatment plant in a form of outward transportation to perform reduction treatment.
The sludge dewatering technology refers to: the sludge in fluid state is physically dewatered and converted into semi-solid or solid mud cake. Mainly comprises three aspects of belt filter pressing, plate and frame filter pressing and centrifugal dehydration. In order to improve the efficiency of sludge dewatering, the sludge is generally pretreated before sludge dewatering, which is called sludge conditioning, and the sludge conditioning methods include four methods, namely a chemical conditioning method, a heat treatment method, a freezing method and a elutriation method.
Anaerobic fermentation technology refers to: under anaerobic condition, the organic matters in the sludge are converted into methane or volatile organic small molecular acid under the action of microorganisms, so that the organic matters in the sludge are stabilized. Anaerobic digestion can reduce the content of organic matters in the sludge, reduce the volume of the sludge and improve the dehydration performance of the sludge. Before anaerobic fermentation treatment, sludge is generally pretreated, including an acid pretreatment technology, an alkali pretreatment technology, an ultrasonic pretreatment technology, an oxidation pretreatment technology, a microwave pretreatment technology and the like, wherein the high-temperature thermal hydrolysis pretreatment technology is widely applied.
The aerobic composting technology is as follows: and the organic matters in the sludge are converted into stable humus under the biological metabolism of aerobic microorganisms under high-temperature aerobic conditions.
The lime stabilization technique refers to: the process comprises adding a certain proportion of quicklime into the dewatered sludge, mixing uniformly, reacting the quicklime with water in the dewatered sludge to generate calcium hydroxide and calcium carbonate, and releasing heat to stabilize the sludge.
The sludge drying technology is as follows: and removing most of the water from the sludge by infiltration or evaporation. There are steam type, hot air type, etc. At present, the sludge drying process equipment with more applications comprises six process equipment, such as fluidized bed drying, belt drying, blade drying, horizontal rotary disc drying, vertical disc drying and spray drying.
The sanitary landfill technology refers to: the sludge is simply disinfected, mixed with other garbage, poured into a pit body of a garbage landfill, and covered with soil, compacted and landfilled.
The incineration technique refers to: and heating and drying the dehydrated sludge by an incinerator, and oxidizing organic matters in the sludge at high temperature to make the sludge become a small amount of ash. The method is divided into a direct incineration technology and a mixed incineration technology.
The prior art has certain problems including: technical disadvantage of in-situ sludge reduction: the technology is immature and difficult to operate; technical disadvantage of ectopic sludge reduction: the economic cost is high, and odor is easy to leak in the process of outward transportation; technical disadvantages of sludge dewatering: the stability and sterilization are insufficient, malodor is generated, and the organic matter content in the sludge is not reduced; anaerobic fermentation technology has the defects that: the temperature required by anaerobic digestion is maintained, a large amount of heat energy is consumed, the residence time of the anaerobic digestion process of the sludge is longer, the volume of an anaerobic digestion tank is large, the water content of the sludge after anaerobic digestion is still higher, and the subsequent treatment is needed; the technical defects of aerobic composting: long residence time, large volume, poor sanitary condition, and large amount of odor generated in the composting process, thereby polluting the surrounding environment; technical disadvantages of lime stabilization: because the lime addition amount is large, the reduction degree is low compared with other processes, the treated sludge is strongly alkaline, the land use value is low, the surface is narrow, and the medicament use cost is high; the technical disadvantage of sludge drying: the investment is large, the energy consumption is high, the operation cost is high, malodor is easy to generate, the dust control requirement in the drying process is strict, and potential safety hazards exist; technical disadvantages of sanitary landfills: the influence on the landfill site is large, and the problems that the soil and the underground water are polluted by heavy metal components contained in the sludge and the like are possibly caused by improper landfill treatment; the technical defects of incineration: the operation cost is high, and atmospheric pollution and the like can be generated when the treatment is improper in the treatment process.
The livestock and poultry manure treatment background technology comprises the following steps:
the full-scale technology of the excrement: and collecting the excrement, the fecal water and the sewage generated in the farms in a concentrated way, storing all the excrement, the fecal water and the sewage in an oxidation pond, carrying out harmless treatment on the excrement and the sewage through the storage of the oxidation pond, and carrying out farmland utilization in fertilization seasons.
Mode of fecal composting: after innocent treatment of aerobic composting, the organic fertilizer is utilized or produced in the farmland on site.
The mode of feces energy utilization: and (3) carrying out anaerobic fermentation on the manure and the manure water of the farm, surfing the net through biogas power generation or purifying biological natural gas, and carrying out farmland utilization of organic fertilizer produced by biogas residues or advanced treatment on the farmland utilization of biogas slurry to reach the discharge standard.
Fecal padding technology: after solid-liquid separation of the manure, the solid manure is subjected to aerobic fermentation harmless treatment and then reused as a cattle bedding material, and the sewage is stored and then used as a fertilizer for farmland utilization.
Fecal fodder technology (mainly for breeding earthworms, maggots, hermetia illucens, etc.): and (3) composting and fermenting dry manure, earthworm, fly maggot, black soldier fly and other animal proteins in the livestock and poultry cultivation process, producing organic fertilizer for agricultural planting, and using the fermented earthworm, fly maggot, black soldier fly and other animal proteins for preparing feed and the like.
Fecal fuelling technology (biodesiccation, biomass briquette fuel): and (3) stirring the livestock manure, dehydrating, extruding and granulating to produce the biomass fuel rod.
The prior art has certain problems including: the technical disadvantage of the total amount of the excrement is that: the excrement storage period is generally more than half a year, and enough land is needed to build an oxidation pond storage facility; the fertilization period is more concentrated, and specialized stirring equipment, fertilization machinery, farmland application pipe networks and the like are required to be matched; the long-distance transportation cost of the excrement is high, and the excrement can be only applied in a certain range. Technical disadvantages of fecal composting: the aerobic composting process is easy to produce a great amount of odor and is only suitable for poultry farms or sheep farms and the like which only produce solid manure and no sewage. Technical shortcoming of fecal sewage energy: the disposable investment is high, the utilization difficulty of energy products is high, the biogas slurry production is large and concentrated, the treatment cost is high, and the subsequent treatment and utilization process is needed. Technical disadvantages of faecal litter formation: as a bedding material, such as innocuous treatment is not thorough, and a certain biological safety risk may exist. Technical disadvantage of fecal feed conversion: the requirements on animal protein raising temperature, humidity and air permeability of the raising environment are high. Technical disadvantage of fecal fuelling: the energy consumption for dehydrating and drying the excrement is high.
