Description

The method of pit type high-temperature aerobic biological fermentation deodorizer and the organic stench castoff compost of degraded

Technical field

The invention belongs to a kind of biological fermentation field, i.e. aerobe deodorizer and biodegradation method, the method for particularly a kind of pit type high-temperature aerobic biological fermentation deodorizer and the organic stench castoff compost of degraded.

Background technology

The discarded organic treatment capacity of China's stench is big and wide, the stench waste that particularly influence ecological environment is big, as livestock and poultry manure, domestic refuse, mud, industrial residue, industrial biomass garbage, food garbage or the like, a large amount of stalks in rural area in addition, they have become the hang-up of China's environmental pollution anxious to be solved.

China's feces of livestock and poultry, domestic refuse, municipal sludge does not also comprise industrial sludge, industrial residue, industrial filter mud, becomes three big odor pollution sources, it is very severe that town dweller's health is subjected to the aerocolloidal pollution of stench.

All organic waste common features are both at home and abroad: just be in the anaerobically fermenting state once entering physical environment, because the flora of anaerobically fermenting is the main body flora with the anerobe of acid-producing bacteria, methanogen two big classes, their degradeds are discarded organic, produce a large amount of volatility [colloidal sols, sulfocompound (hydrogen sulfide, mercaptan etc.), nitrogenous compound (ammonia, amine etc.), methane, organic acid, alcohols, aldehydes or the like are wherein arranged, and CO ₂With a large amount of stench water from diffusions of discharging.

The common technical barrier that exists of domestic and international organic stench waste biological treatment: the one, volatility [collosol concentration is big, and is unpleasant, and HUMAN HEALTH is caused very big harm, and a large amount of dischargings need foul smell is administered, otherwise are difficult to handle; The 2nd, not only dirty, not only smelly but also mashed, mosquitos and flies multiplies, and handles nowhere and takes part in; The 3rd, the moisture content height increases intractability; The 4th, there are many organic wastes originally to can be used as resource recovery and utilization, but abandon it because of stench, the wasting of resources is very big; The 5th, in the treating processes, to adorn, transport, unload, logistics capacity is big; The 6th, floor space is big, and work under bad environment needs certain processing cost; The 7th, the trickling of stench water from diffusion need be carried out special administration.

Ordorless organic waste still can burn and make fuel, and the burning of stench organic waste expends a large amount of energy, and cost is too high, also forms secondary environmental pollution.Forbidden stench organic waste landfill in European Union and North America.

One, domestic and international organic stench waste biological treatment main technique has following a few class:

(1) organic stench waste is stacked to rectangular, but turning regularly 5～6 times, genuss anaerobically fermenting is a main body, the technology of 30 minutes aerobic fermentations during turning, this has been an external main popular organic waste facture since the nineties.

(2) organic stench waste is entered in " Danot " tube by charging opening, rotate with per minute 1-2, pass to the air-flow oxygen supply, and the foul smell that will volatilize adsorbs and to enter the deodorizer deodorizing, this method is dynamic aerobic fermentation process.Denmark's invention, various countries all have some producers, also have U.S. thomas fermentation tower, Hangzhou, China Wuxi fermentation tower, but now less use.

(3) organic stench waste heap ridge is become rectangular, belong to static anaerobic ferment process, domestic destructor plant belongs to this type of more, belongs to eliminating technology.

Two, now domestic and international organic stench waste and organic waste are at present handled the popular fermentation process analyze, cause in second class and become superseded technology, will not discuss because of less use, the 3rd class bar buttress static compost.

1, with the correlation parameter of CNS GB7959 During High-Temperature Composting hygienic standard and discriminating as foundation, all kinds of compost fermentation methods are analyzed and are compared.

(1) method for supplying oxygen and the characteristic sign of bar buttress (ridge) compost: bar is piled up neatly compost countries such as the Canadian scarab of German bus storehouse (BACKHUS), Austrian how general too (TOPTURN), North America, U.S. wildcat abroad, since the last century the nineties, bar buttress (ridge) formula compost and turnover throwing machine have been widelyd popularize abroad, bar buttress formula compost carries out turning, its principle is that the throwing drum that turns over of turnover throwing machine has higher revolutions, produce bigger air quantity, the one, make airborne oxygen and fermentation materials fill part and contact oxygen supply; The 2nd, the fresh air that produces is wrapped on the compost particle, and be full of among the space that is trapped in compost, when the intergranular porosity of compost is 30-77%, if only depend on the turning oxygen supply, then the oxygen that is full of in the gap between compost (60 ℃) particle was just run out of by aerobic microbiological in about 30 minutes, in other words, the aerobic fermentation state that keeps bar buttress formula compost, must be once every turning in 30 minutes, obvious this method is infeasible, the Chen Shihe of Tongji University professor carried out measuring and calculating in 1989.

Therefore, turning every other day is known as bar (ridge) the buttress formula compost of aerobic fermentation, be 48 hours general pitch time, and maximum ventilation oxygen supply time of turning is 30 minutes, and oxygen supply time only accounts for 1.05%, and the anaerobism time is 98.95%, above data fully prove: bar buttress formula compost, and turning every other day is that a kind of anaerobically fermenting is a main body, and with the compost of short period of time (30 minutes) aerobic fermentation, the rotary drum of the high revolution of so-called turnover throwing machine is to the compost oxygen supply of ventilating, only can be for microbial consumption 30 minutes.

Bar buttress compost is that anaerobically fermenting is main, and following three big characteristic signs are arranged:

Bar buttress formula compost volatilizes a large amount of stenches in the turning process, must spray reodorant and eliminate stench, and in addition, the water from diffusion that contains a large amount of repugnant substances is smelly, has again, and mosquitos and flies multiplies around bar ridge and the water from diffusion.

(2) bar buttress (ridge) compost ventilation oxygen-supplying amount data show that bar buttress compost is that anaerobically fermenting is main compost.

The turning every other day of bar buttress (ridge) compost, the ventilation 12m of each turning ³/ hm ³, be 40 days as yeast phase, getting the maximum ventilation oxygen-supplying amount is 0.2m ³/ minm ³The time, by maximum turnings 20 times 600 minutes, 20 times ventilate was 240m ³/ m ³Need to prove that a turning is 5-6 time in general 40 days of the bar buttress compost, ventilation only is 60-72m ³

Above data prove absolutely, bar buttress compost relies on turning to ventilate, oxygen-supplying amount wretched insufficiency then, even turning is 20 times at most, time material more than 93% still is in the anaerobically fermenting state, and as turning 5-6 time, then the time material more than 98% is in the anaerobically fermenting state, bar buttress compost is that anaerobically fermenting is a main body thus, has only the method for of short duration 30 minutes aerobic fermentations.

(3) bar buttress compost is middle low temperature fermentation compost, and its security is difficult to guarantee.

1) bar buttress (ridge) formula compost is middle low-temp anaerobic fermentation, heating-up time is about 7～9 days, thereafter core enters high-temperature zone (45-60 ℃), warm area and normal temperature district (20-45 ℃) during other parts (around top, bottom and the core) are then kept, temperature all changes after each turning, and needing heats up again just can enter the pliotherm period, continue 20-28 days, enter cooldown period then, become thoroughly decomposed the phase, turning 5～6 times, fermentation period is 40-50 days.

2) distribution of bar buttress (ridge) formula compost fermentation temperature of charge and moisture content as shown in Figure 2.

The temperature of fermentation materials and moisture content are made of four zones, promptly

1 district is the region intermediate of bottom, and temperature fluctuates with weather, temperature and temperature, but surface temperature is comparatively stable, generally between 25～35 ℃, shared volume is that 30%, 1 district (bottom) moisture content is moisture content highest region territory in the compost, the one, and the own moisture content height of fermentation materials (45～60%); The 2nd, because of moisture content density greater than material density, the moisture content sinking diafiltration to 1 in upper strata (2 districts, 4 districts) district; The 3rd, core temperature is higher, carries out the also district of diafiltration to 1 downwards of the organic new moisture content that produces of anaerobically fermenting degraded; The 4th, when the moisture content accumulation is higher than the saturated moisture content of material, forms water from diffusion and trickle to out-pile.

2 districts are cores of trapezoidal (ridge) buttress formula compost, it is the high-temperature zone of leavening temperature＞45 unique in the bar buttress formula compost ℃, temperature is 45～60 ℃, about 20% of shared cumulative volume, but 2 districts (core) needs the static temperature raising period through 7～9 days just can enter the pliotherm period, when carrying out turning technology, temperature raising period then need prolong, and each thereafter turning all needs the temperature raising period more than 1-3 days just can enter the pliotherm period.

2 districts (core) are high moisture content zones, the one, and because of no ventilation system, fermentation materials keeps average moisture content 45～60%; The 2nd, material anaerobion degradation speed under 45～60 ℃ of temperature condition is fast, the moisture content that degraded makes new advances, wherein have only the sub-fraction vaporized gas can rise to top, 4 district, be evaporated in the atmosphere, and in a part of sinking diafiltration to 1 district water from diffusion, a part then is retained in 2 district's materials, and therefore, 2 district's moisture content are higher.

3 districts are the left and right sides peripheral portion of core, are made up of left and right two districts, and this distinguishes temperature, influenced greatly by core temperature, but temperature are lower than core temperature, and this district's temperature is 25～45 ℃, and based on mesophilic bacteria, this is distinguished shared volume and is about 15～20%.

The average moisture content of 3 district's moisture content is higher, produces new moisture content because of the mesophilic bacteria group degrades, and does not ventilate and can't evaporate because of having, and is retained in the material.

4 district bars buttress expose the zone, top and 2 district cores link, inside, both sides and periphery, 3 district link.

4 district's temperature are limited by climate change, seasonal variation, day and night temperature Change, temperature is between normal temperature to 35 ℃, and moisture content is limited by open-air still builder's temporary shed operation, is limited by the temperature difference in dry season or rainy season, temperature and moisture content change greatly, and temperature remains on normal temperature, and this district accounts for cumulative volume 35～40%.

Bar buttress formula compost temperature≤45 ° has 1 district (30%), 3 districts (15～20%), 4 districts (35～40%) to the zone between the normal temperature, add up 80～85%, temperature only has 2 districts (about 20%) at 45～60 ℃, bar buttress formula compost be in (low) warm compost, with anaerobically fermenting is main fermentation mode, and accompanies by of short duration (30 minutes) aerobic fermentation compost of turning.

3) low temperature compost in the bar buttress compost fermentation material system is far apart with the During High-Temperature Composting of state health standards.

Bar buttress compost utilizes the method for turning, most material is reached and keep temperature more than 50～55 ℃, continue 5-7 days, may not, bar buttress compost 80～85% materials are normal temperature-middle temperature, material is difficult to realize high temperature, and the compost hygienic standard that therefore can't reach a high temperature more can't realize innoxious.

But following experimental test data form the basis.

Stack in the open according to external Hay and Kuchenrither, be through the result that turning is tested for 5～6 times to many rule buttress formula compost for a long time:

Bar buttress compost fermentation in August detected result in the time of 33 days, coliform number＜1MPN/g.

Bar buttress compost fermentation in February detected result in the time of 50 days, coliform number＞1MPN/g.

Verification test result explanation both at home and abroad: bar buttress formula compost is middle low temperature compost, because the material medial temperature does not reach 45 ℃, compost material be difficult to reach a high temperature 50 ℃ of compost more difficultly reach During High-Temperature Composting hygienic standard more than 55 ℃.

In a word, in cryogenic buttress compost be difficult to reach every index of China national During High-Temperature Composting hygienic standard, therefore be difficult to guarantee its fertilizer security, reliability.

(4) water from diffusion of bar buttress compost trickles and mosquitos and flies multiplies contaminate environment everywhere.

Bar buttress formula compost is based on anaerobically fermenting, and is equipped with the short period of time aerobic fermentation of turning every other day, and bar buttress compost gives out a burst of stench when blowing and attracts external mosquitos and flies, gives out a large amount of foul odours during turning and causes a large amount of fly mosquitos on every side and fly on the bar buttress.

The one, enter the material of anaerobically fermenting, the anaerobion degraded produces water, CO ₂And foul smell; The 2nd, anaerobism material moisture content is higher, moisture content diafiltration in heap height＞1.2～1.8m material is to the bottom, when surpassing the saturated moisture content of material, bar buttress both sides trickling water from diffusion is because bar buttress compost fermentation temperature is low, but its material ventilates, moisture content can't evaporate, and heat can't be regulated, and fermentation time is oversize, therefore, the water from diffusion of bar buttress compost is more.

The water from diffusion that bar buttress compost is discharged is black, smelly, contains not degradation of organic substances COD in the water, BOD, NH ₃-N and phosphoric acid salt have dense stink, become the place of fly mosquito hobby.

(5) foul smell of bar buttress (ridge) formula compost volatilizees in a large number, atmosphere pollution, and treatment process is that spray is with reodorant.

(6) logistics capacity of bar buttress compost is big

Bar buttress compost utilizes shovel loader that dump truck is unloaded 60～80% stockpile need carry out " loading-lifting-discharging ", pile high trapezoidal of 1.5m, have only 20～40% stockpiles can be made for bottom and use, loading and unloading can not be carried out synchronously with heap ridge buttress, the logistics capacity length that expends time in, efficient is low; It is trapezoidal to utilize shovel loader that the material loading is piled, and the logistics capacity height of bar buttress increases cost and consumption.

(7) piece a buttress formula compost be a kind of in low temperature fermentation, 80% above temperature of charge＜45 ℃, organic matter can't be degraded fully, so is difficult to become thoroughly decomposed fully.There is following problem:

1) material of the organic matter that does not become thoroughly decomposed in the bar buttress compost after being manured into soil, continues degraded and can produce organic acid, can produce compositions such as hydrogen sulfide and stench under reductive condition, these materials can suppress seedling germination and growth, even burn seedling, also can poison crop root, even burn root.

2) after the organic matter that does not become thoroughly decomposed in the bar buttress compost is manured into soil,, cause the microorganism aggravating activities, cause microorganism and crop root to strive oxygen, and influence the root system normal growth because of needs continue degraded; When C/N is higher, cause microorganism and crop to strive nitrogen, cause the crop nitrogen stress to influence plant growth; When C/N crosses when low, can cause the crop ammonia poisoning again.

3) anaerobic composting system, middle low temperature fermentation compost still exists part pathogenic bacteria, parasitic ovum, weeds seed etc., might become propagating source.

Because there is above-mentioned defective in bar buttress compost, is badly in need of handling rationally and effectively the method for the organic stench waste in city.
