Description
Technical field: the present invention relates to organic solid waste and handle, particularly organic solid waste is produced the deodorizing processing in the organic compost process.
Background technology: along with The development in society and economy, quickening of urbanization process, the increase of urban population, the raising of living standards of the people, the generation of domestic waste is also constantly increasing.Since 1979, on average with the speed increment in every year nearly 10%, the rate of increase of a few cities is up to 15%～20% for the Chinese city domestic refuse.So huge quantity of refuse is discarded in environment, has both surpassed the naturally ability of dissolving, severe contamination water body, atmosphere, soil, and the harm ecotope and the people's health influences urban development, has caused the significant wastage of resource again.Therefore, how to make that domestic waste is innoxious, minimizing, resource utilization, turning waste into wealth becomes the big and medium-sized cities problem demanding prompt solution.
It is one of most widely used in the world three kinds of waste disposal methods at present that the composting process of domestic refuse is handled.And, adopt composting technology processing organic solid waste and mud just becoming more and more extensive because it has, resource utilization degree advantages of higher little to environmental hazard.
Composting process is to rely on microorganisms such as the extensive bacterium that exists of occurring in nature, actinomycetes, fungi, promotes controllably that artificially the organism that can be degraded by microorganisms in the rubbish is converted into the Biochemical processes of stable soil ulmin.Its product-compost can become the soil improvement agent that imposes on farmland, orchard, nursery, improves the soil property in poor ridge soil, provides growth required nutritive element to crop.It both can solve the problem of outlet of municipal wastes, can reach the purpose of resource utilization again, had good economic benefit and social benefit.Therefore, compost treatment is regarded as solving the approach of a significant of domestic waste, sewage sludge treatment.But in the actual motion of domestic waste and sludge composting factory, a subject matter of existence be in the composting process and composting production in the generation of foul odour, and in composting process, grow a large amount of mosquitos and flies.So both severe contamination the environment of plant area and peripheral region, the physical and mental health of harm garbage compost staff of plant area and surrounding resident has also reduced the commodity value of composting production widely, directly has influence on the survival and development of composting production on fertilizer market.
Foul gas can be divided into five classes by chemical constitution: 1. sulfocompound, as hydrogen sulfide, sulfurous gas, mercaptan, thioether; 2. nitrogenous compound is as amine, acid amides, indoles; 3. halogen and derivative are as chlorine, halohydrocarbon; 4. hydro carbons: alkane, alkene, alkynes, aromatic hydrocarbon; 5. oxygen-containing organic compound is as alcohol, phenol, aldehyde, ketone, organic acid etc.The method of handling foul smell has technology such as soda acid absorption, chemistry are covered, chemisorption, catalyticcombustion, microbial deodorization usually.Disclose a kind of air deodorization agent and deodorizing method as Chinese 90101673.X patent application specification, this reodorant contains citric acid, lactic acid, D-tartrate; No. 00106382.0 patent application specification of China discloses a kind of quick-acting biologically deodouring agent, this quick-acting biologically deodouring agent will make up by microorganism species such as isolating thermophilic microorganism, heat-resistant bacillus, pseudomonas, Xanthomonas campestris from soil, compost, can eliminate the foul gas in organic ight soil.Though these reodorant have certain effect, but owing to only used single deodorization technology, usually can not reduce the generation of foul gas new in the compost treatment process or can not remove stench foul smell in the different domestic refuse of all kinds of compositions quickly and efficiently, can not quicken the compost maturity process and shorten the production cycle.
Summary of the invention; Original various foul gass in the rubbish are covered, removed to the method that the object of the present invention is to provide a kind of reodorant, deodorizing modifying agent and compost deodorizing to handle, at active adsorption, and reduce the new foul gas of generation in the garbage compost process significantly.
The technical scheme that realizes the foregoing invention purpose is: reodorant contains chitosan, acetate and spices, the component of this reodorant and the weight proportion of each component are as follows: chitosan 0.2-1.2%, acetate 1-6%, spices 0.01-0.03%, water 93-98%; The deodorizing modifying agent contains rhamnolipid and sucrose fat, and the weight proportion of each component of deodorizing modifying agent is as follows: rhamnolipid 0.2-1.2%, sucrose fat 0.2-2.0%, water 97-99%; The method that the garbage compost deodorizing is handled is in cheating gathering materials before the refuse classification system, to press 1～3% of rubbish weight and add diluted reodorant; In the mixed stirring device behind refuse classification, press 1～6% of rubbish weight then, add diluted deodorizing modifying agent.
