Abstract
A kind of method of utilizing cities and towns human excrement processing compoiste fertilizer, this method comprises puts into reodorant with human excrement in collection process, enter hold tank after filtration, add solid adsorbent and anaerobic species when squeezing into the stirrer stirring with pump, make dry matter content greater than 20%, send into warm solid fermentation in the anaerobic fermentation tank after the stirring, the fermentation back adds inorganic fertilizer and a little binder such as suitable nitrogen, phosphorus, potassium, after granulation, oven dry, packing, be finished product, product effective constituent 〉=20%, content of humic acid 〉=10%.
Description
The present invention relates to a kind of method of utilizing cities and towns human excrement and small amounts of inorganic chemical fertilizer to make compoiste fertilizer.
The common urban night soil of China is handled, and based on aerobic pile fermentation, is about to domestic waste and transports to the processing field, removes nondigestible part through screening, adsorbs human excrement then, and natural air drying is stored behind the aerobic pile fermentation.This organic fertilizer of soil life-time service is difficult to the material that digests in a large number owing to contain in the fertilizer, as plastics, heavy metallic salt etc., thereby has seriously destroyed the ecosystem in farmland, has polluted soil and farm crop.This production method, the production scene [fills the air, and grows the maggot fly in a large number, causes secondary pollution, and sanitationman's Working environment is exceedingly odious.
891014519 " manufacture method of organic-inorganic composite fertilizer " patented technologies that provide number are provided nearest Chinese patent application, after human faecal mass and poultry manure be mixed in proportion stirring, manufacturing procedure is followed successively by filtration, fermentation, concentrated, compound, dry, granulation and packing, this complete processing is not done any deodorizing and is handled before fermentation, thereby be detained strong ight soil foul smell in the course of processing, unfavorable to staff's health.During fermentation, ight soil in digester temperature 20-35 ℃ kept 10-15 days, this temperature and time can not play the intestinal bacteria killed more than 98% and the effect of parasitic ovum.Do not reach the national health index.Simultaneously, emit a large amount of waste water in the thickening filtration process, cause new environmental pollution.In addition, the desiccant import hot air temperature of this technology is 250-450 ℃, and time 30-60 minute, under these circumstances, inorganic nitrogenous fertilizer commonly used will decompose in a large number.
The objective of the invention is a kind of method of utilizing cities and towns human excrement and a spot of inorganic fertilizer to produce compoiste fertilizer, the compoiste fertilizer of manufacturing with method of the present invention can impose on multiple soil and plant variety, be no stink processing in the production technique of the present invention, and effluent sewerage does not adopt the compoiste fertilizer of the inventive method making to contain a large amount of humic acidss and mineral manure.Face is the composite fertilizer that a kind of quick-acting slow has both, and helps improving the soil, and promotes plant growth.Another object of the present invention is to make human excrement innoxious, makes agricultural-food pollution-free, improves the town environment sanitary condition.
The object of the present invention is achieved like this, in collector's fecaluria, adds an amount of reodorant, removes the foul smell of ight soil substantially, makes it be odorless processing in whole process.Enter hold tank behind the grid filtration after filtration, hold tank is the normal pressure open type.Send into stirrer by the pump housing then, simultaneously, sorbent material and anaerobic species are sent into stirrer, send into anaerobic fermentation tank behind the mixing, carry out solid anaerobic fermentation in fermentor tank, leavening temperature is 30-45 ℃, and the time is more than 20 days, make ight soil digestion, and kill parasite egg, pathogenic bacterium and virus, and the sorbent material of putting into simultaneously also ferments and is organic fertilizer, and the biogas that produces in the fermentor tank enters gas-holder, boiler oil is provided, and the steam that boiler produces is used for fermentor tank and moisture eliminator.The material of anaerobic digestion after testing after; disposablely from fermentor tank, take out; add inorganic fertilizer and a little binder that contains compositions such as nitrogen phosphorus potassium on demand; after the machine of being mixed is mixed evenly, send into the tablets press granulation, drying device drying; moisture eliminator import hot air temperature is 80-132 ℃; the face time is 30-60 minute, makes its moisture vaporization and drying, dried particle water content≤5%.The total effectively fertile amount 〉=20% of this product.
Fig. 1 is a process flow sheet of the present invention.
With reference to Production Flow Chart shown in the drawings, can understand the production process route of compoiste fertilizer of the present invention.At first, when sucking the pot type transport trolley, add an amount of reodorant, in the process of transportation, the abundant and reodorant reaction of ight soil makes it the basically eliminate foul smell.When hold tank discharges ight soil, filter impurity such as brick, branch, rubber, plastics from transport trolley with the screen cloth grid, the fecaluria liquid dry matter content that is discharged into hold tank is about 9%.With pump ight soil is sent into stirrer then, meanwhile, sorbent material and anaerobic species are sent into stirrer, the material dry matter content is reached more than 20%.Send into after stirring fermentor tank carry out in warm solid anaerobic fermentation, leavening temperature is 30-45 ℃, fermentation time is more than 20 days, the biogas that produces in the fermenting process enters gas-holder, fermentation back material after testing after, disposablely from fermentor tank, take out, after mixing, the machine of being mixed sends into the moisture eliminator drying with the inorganic fertilizer and the tackiness agent that contain compositions such as nitrogen, phosphorus, potassium on demand, the heated dry air inlet temperature of moisture eliminator is 80-132 ℃, make its moisture vaporization water content≤5%, be finished product after the fertile packing of dried particle.The sorbent material of putting in the course of processing of this inventive method is fermented into fertilizer simultaneously at fermentor tank.The biogas that produces in the fermentor tank enters gas-holder and stores, and the biogas that is stored up is as the thermal source of boiler, and the steam of discharging from boiler is for fermentor tank and the moisture eliminator usefulness of heating.
Embodiment:
In human excrement 2000kg suction tank car; add simultaneously reodorant 225g gradually; be transported to and handle the field; filter by grid and aperture 1.5cm wide-meshed screen; liquid manure enters storage tank after removing foreign material; sensation in operator's sense of smell this moment does not have obvious stink; with pump the liquid manure in the storage tank is squeezed in the stirrer; simultaneously to wherein adding sorbent material and anaerobic species; stir and be heated to 40-45 ℃; the material solids content is 23%; deliver to and carry out solid fermentation in the anaerobic fermentation tank; through 25 days; at 35 ℃ of temperature bottom fermentations; content of humic acid is 20.6%; with the water content after the anaerobic digestion is that 21% fermented product is promptly sent in the machine of being mixed and is mixed in proportion; fermented product: urea: diammonium phosphate: Repone K=89.1: 9.4: 19.1: 1.1; add various inorganic fertilizers and add tackiness agent simultaneously to improve particle intensity; moisture 15.8% material is sent into the tablets press granulation; send the fluid bed dryer drying with pellet; 90 ℃ of 50 minutes time of drying of hot-air inlets temperature; particle is moisture 4.3%, discharges and packing obtains finished granule fertilizer from the moisture eliminator end opening, and per 100 kilograms of starting material can obtain fertile 86 kilograms of finished granule; product yield 97.9%; content of humic acid is 14.5% in the finished product fertilizers, nitrogen; phosphorus; potassium content is respectively 10-10-5%, all ordorless smell of product; no parasitic ovum and pathogenic bacterium in the product meet the national health index after testing.
