Description
Technical field
The invention belongs to the compost treatment technical field, particularly a kind of no auxiliary material sludge composting method.
Background technology
Compost is to utilize microorganisms such as the extensive bacterium that exists of nature, actinomycetes, fungi, promote that controlledly biodegradable organism is to the microbiological process of stable class soil ulmin biochemical conversion in the solid waste, under certain temperature, humidity, carbon-nitrogen ratio, oxygen level, pH value condition, make organism generation biochemical degradation, form a kind of material of similar humus soil.
Mud is the product after the sewage disposal, is a kind of heterogeneous body of the complexity of being made up of organic relic, bacterium thalline, inorganic particle, colloid etc.Its main characteristic is water ratio height (can up to more than 99%), and the organic content height is degenerated smellyly easily, and particle is thinner, and proportion is less, is gluey liquid.
Along with the high speed development of sewage treatment industry, the generation of mud is increasing, and the handling problems of mud is but shelved for a long time, and the secondary pollution problem day that causes mud to cause shows outstanding, and the safe disposal problem of mud is urgent day by day.Than muds such as landfill, burnings, compost treatment can realize the recycling of mud, is the most promising method for sludge treatment.But because the characteristic of mud uniqueness, present sludge composting technology all needs to add a large amount of auxiliary material (the auxiliary material addition is about the 40%-50% of sludge quality), the effect of auxiliary material is features such as the water ratio of regulating compost material, structure, carbon-nitrogen ratio, be beneficial to the compost fermentation that heats up smoothly, killing pathogenic bacteria, realize the innoxious of mud, the heap body is become thoroughly decomposed, its common title has weighting agent, additive, amendment etc., and auxiliary material commonly used has wood chip, agricultural crop straw, wheat bran, mushroom slag, greening waste, Herba Eichhorniae, flyash etc.Adding auxiliary material makes composting process increase the operation that batch mixing stirs on the one hand, need corresponding equipment and energy consumption, buy auxiliary material on the other hand and need a large amount of fund and freight charges, the cost of these auxiliary materials rises year by year in recent years, it is also limited to originate, cause the compost cost to increase, limited the development of sludge composting technology.
Summary of the invention
The objective of the invention is to provides a kind of no auxiliary material sludge composting method at having the difficult problem that the sludge composting Technology Need adds a large amount of auxiliary materials now.
The technical solution used in the present invention is:
A kind of no auxiliary material sludge composting method may further comprise the steps:
1) preparation of sludge composting special leaven: in the composting process, in 10-75 ℃ of scope, get the mud sample of differing temps, add physiological saline respectively, get filtrate after the concussion, filtrate is placed nutritional medium, cultivate 48-72h obtaining under the corresponding temperature of mud respectively, obtain the sludge composting special leaven;
2) no auxiliary material sludge composting: mud is carried out pre-treatment, make its water ratio be down to 40-65wt%, seed sludge compost special leaven composting 15-25 days, namely gets matured compost.
Preferably, the volume ratio of described filtrate and nutritional medium is (0.1-0.2): 1.
Preferably, the living bacteria count of described sludge composting special leaven is 4 * 10
8-6.5 * 10
8CFU/ml.
Preferably, step 2) in, in composting process, differing temps section inoculation corresponding temperature is cultivated the sludge composting special leaven that obtains.
Preferably, in 10-75 ℃ of temperature range, 15-25 ℃ of inoculation corresponding temperature cultivated the sludge composting special leaven that obtains at interval.
Preferably, the add-on of sludge composting special leaven is for handling the 0.1-0.5wt% of sludge quantity.
Preferably, step 2) in, make heap body oxygen level remain on 5-15v/v% in the composting process.
The invention has the beneficial effects as follows:
The indigenous microorganism that the present invention will extract from differing temps compost mud is cultivated, obtain the sludge composting special leaven, temperature section in correspondence is inoculated in mud with it then, microorganism in the starter can adapt to the environment of compost mud within a short period of time, and breeding fast starts compost, the organic degraded fast of windrow, heap body quick composting, and composting production steady quality have been realized no auxiliary material sludge composting.The starter of high temperature section preparation is inoculated in compost mud, can make heap height temperature longer duration, and effectively killing pathogenic bacteria reduces the generation of foul smell in the composting process.Compost method of the present invention has been simplified composting process, and has been saved the compost cost owing to need not add auxiliary material, and the compost production environment cleans very much.
Embodiment
The tradition composting mode normally adds the fermenting agent of artificial culture in the mud, the special microbial inoculum of artificial culture has characteristics such as breeding is fast, active by force, decomposing organic matter is rapid, but also there is the artificial contained microbe species limited amount of microbiobacterial agent that adds, decompose problems such as object and capacity of decomposition there are differences, cause the compost effect of different microbial inoculums mud of the same race and the different mud of microbial inoculum of the same race obviously different.And studies show that, single bacterium, fungi, actinomycetes colony, no matter how high its activity is, and the effect in accelerating the composting process is all less than the acting in conjunction of multiple microbial population.In addition, because the organic matter fraction of mud material there are differences, corresponding microbial population and suitable temperature thereof are also different.The fermenting agent in foreign bacteria source adds in the mud, and it is folded to be easy to generate ecological niche as foreign bacteria and indigenous microorganism, and adaptability and competitive power are not as indigenous microorganism.
Composting process is the dynamic process of being realized by the very fast a plurality of microbial population actings in conjunction of structure of community succession, microbial population utilizes available organic compound in the mud to carry out the metabolic activity of self, thereby biodegradable organism is transformed to stable soil ulmin, and emit energy, make and pile the body heat production.Along with the variation of heap temperature, the part microbic activity increases, and other microorganisms then are suppressed, and the succession phenomenon of population takes place.At the compost initial stage, leading microorganism comprises fungi, bacterium and actinomycetes to have a liking for the warm nature microorganism, and mainly decomposing substrate is more labile organism such as carbohydrate, starch based.The heap body rises to certain temperature, has a liking for warm microorganism and is suppressed, and thermophilic microorganism rises to leading microorganism, and organism such as beginnings such as hemicellulose, Mierocrystalline cellulose and protein complicated in the compost are decomposed strongly.
The present invention considers above-mentioned factor, from composting process, extract indigenous microorganism in the mud of differing temps, obtain the sludge composting special leaven through cultivating, the differing temps section at sludge composting drops into the special leaven that corresponding temperature is cultivated then, does not have the auxiliary material compost.Special source, culture condition and the addition means of this starter, make its micropopulation physical efficiency adapt to the environment of compost mud within a short period of time, breeding fast, and promote rapidly to ferment, organic decomposition is played a role, and at the hot stage longer duration, effectively killing pathogenic bacteria realizes the harmless treatment of heap body.
