Abstract
The present invention relates to a kind of complex microorganism nest that utilizes and process the method for liquid dung, comprise the steps: that (1) leaves standstill pretreatment by liquid dung under the condition of isolating oxygen not, makes pretreatment liquid dung; (2) first lay initial bed, then lay padding layer at initial bed upper surface, then spill complex micro organism fungicide to padding layer upper surface paving, after then batch mixing being mixed with bacterium liquid, paving is spilt on complex micro organism fungicide, standing for fermentation, makes complex microorganism nest; (3) pretreatment liquid dung is passed into the upper surface of complex microorganism nest, fermentation, by the complex microorganism nest after fermentation through pulverizing, granulation, make organic fertilizer. The present invention adopts complex microorganism nest to process liquid dung as main thermal source first, and the main moisture in liquid dung is entered in air in the mode of steam, and environmentally safe has solved again the dry problem of liquid dung, does not need to add other energy substances.
Description
Technical field
The present invention relates to a kind of method of utilizing complex microorganism nest to process liquid dung, belong to the dirty comprehensive utilization technique of herding excrement field.
Background technology
The primary pollution source that animal husbandry and urban life produce without the liquid dung of processing. Liquid dung produces foul smell, has a strong impact on weekEnclose masses' normal life and work; Liquid dung has eutrophication, flows into the surface water aquatic organism survival rates such as river and declines, contaminant waterBody; The liquid dung water that permeates the ground, pollutes impact and drinks; Liquid dung be directly discharged into farmland can continue fermentation cause Plants burn root,Soil pH value raises and causes basic soil.
The general liquid dung moisture content without processing, 80～95%, cultivates following (mg/L): the BOD of excrement sewage matter indication range5:1200-15300, CODCr:2720-31000, SS:160-20500; Be subject to the excrement of livestock and poultry without the liquid dung moisture content of processingThe impact of urinary excretion, age, body weight, physiological stage, diet composition, environment temperature etc. As the age and body weight less, rowDischarge is less; Lactation period livestock and poultry compared with period of pregnancy feed intake large, excretion is also large; When diet roughage content is higher, the adopting of livestock and poultryHeavy, digestibility is low, and excretion is large; Summer environment temperature is high, and the amount of drinking water of livestock and poultry is large, and the amount of urinating is also many. Livestock and poultry fecaluriaGeneration also relevant with feeding and management technique with character: dry clear excrement technique fecaluria does not substantially mix in poultry house, and excrement can be independentClear out house, the water content of excrement is in 80% left and right, and this excrement becomes argol; If fecaluria mixes in house, excrement water content is 90%Left and right, is called semifluid excrement; Bubble excrement or water rush excrement water content more than 90%, are called liquid excrement. The generation of three kinds of excrementComputational methods are not identical: argol is only counted fresh excrement amount or fresh excrement and bedding and padding total amount; Semifluid excrement can be by fecaluria total amount; Liquid excrementShould comprise excrement, urine and industrial water amount.
Due to the These characteristics of liquid dung, cause it to utilize difficulty larger, at present main employing utilizes mode as follows:
1, filtrate directly or is after filtering as the raw material that produces biogas, as Chinese patent literature CN103191904A (ShenPlease numbers 201310126581.9) a kind of pig farm dejecta treatment method is disclosed, comprise by the excreta of pig be separated into argol andLiquid dung, argol is done after fermentation process respectively as raw material and the fish meal of producing compoiste fertilizer, and described liquid dung is divided into two parts placeReason, a part of liquid dung enters methane-generating pit for the production of biogas, and another part liquid dung is sent into sedimentation basin for precipitating sterilization, liquid dung warpPrecipitation disinfect after for cleaning pig house. The major defect of the method is: have high input, utilization rate is low, and northern area is inapplicable,The energy obtaining cannot utilize, and cannot obtain cultivating surrounding enviroment and purify, raw material is not reproducible utilize follow-up needs constantly drop into,Price is high, and the seepage water of filtration need to continue to process secondary and drop into, and operating cost is high.
2, the serial initial condition processing such as precipitation, aerobic, anaerobism, as Chinese patent literature CN101654318A (application number200910092443.7) disclose a kind of method of night soil treatment, it comprises the following steps: Separation of Solid and Liquid, flocculation dewatering,The Aerobic Process for Treatment of the Anaerobic Treatment of aerobic compost, sewage, the double oxygen processing of sewage, sewage, the membrane biological reaction of sewage process andStink is administered. The shortcoming of the method is: have high input, operating cost is high, cannot minimizing, resource, cannot obtain cultivation weekSurrounding environment purifies.
3, be directly made into organic commercial fertilizer, as Chinese patent literature CN103848649A (application number 201210504442.0)The fertilizer that discloses production method, equipment and production thereof that a kind of human faecal mass is converted into fertilizer, method comprises the following steps: one,Biogas in septic tank is extracted by extraction machine, and solid, liquid ight soil in septic tank is as original slurry; Two,Original slurry is filtered by filter, remove foreign material, obtain preliminary ight soil slurry; Three, preliminary ight soil slurry is addedAdd drier and be uniformly mixed in mixer, obtain the half-dried slag of ight soil; Four, biogas is done through gas and water separatorDry; Five, dried biogas is burnt, the half-dried slag of ight soil that utilizes the heat of biogas combustion that step 3 is obtained is in evaporationIn device, carry out heating evaporation, obtain the dry slag of ight soil. The shortcoming of the method is: dry is utilized, and the water after pollution cannotProcess.
Therefore, provide a kind of method of comprehensive utilization of liquid dung, prevent secondary pollution, become the crucial difficult point of processing liquid dung.
