Abstract
The invention relates to a method for reducing garbage percolate and accelerating garbage degradation by using saw dust, and belongs to the technical field of garbage treatment. In order to achieve the aim of reducing yield of the garbage percolate and accelerating the garbage degradation, the method comprises the following steps: making the saw dust into a absorbent and a filler, and evenly mixing the saw dust into garbage according to certain proportion, so as to exert the functions of reducing the yield of the garbage percolate and accelerating the garbage degradation by using the saw dust. The method has the advantages of simple and practical operation, lower cost and remarkable effect.
Description
Technical field
The invention belongs to the technology of garbage disposal field, the method that is specifically related to use sawdust decrement percolate and quickens garbage degradation.
Background technology
The processing of percolate is a global difficult problem, the processing method of percolate has been carried out extensive, deep research both at home and abroad, but the minimizing of percolate is studied seldom, and only limits to reduce the research that rainwater enters msw landfill.Concerning some from the nearer refuse landfill of sewage treatment plant, as long as its percolate generation less than 0.5% of sewage treatment plant's amount of disposing of sewage, can be introduced sewage treatment plant by pipe network with percolate and handle.Therefore,, then can alleviate the processing burden of percolate, reduce the disposal cost of percolate if can take the minimizing of technology realization percolate simple to operate, that cost is low.
The degradation rate of house refuse is related to the storage capacity design in garbage loading embeading district, and the degradation rate that how to quicken rubbish is the research focus always.If can adopt and a kind ofly expend the degradation rate that method low, simple to operate is quickened rubbish, and this method do not cause side effects such as increase diafiltration liquid measure, raising percolate pollutant levels index, then can be Solid Waste Treatment and makes certain contribution.
Sawdust is a kind of waste material from timber processing, have be easy to get, inexpensive characteristics.Sawdust has good water absorbing properties and absorption property, therefore can consider to use the biofilm packing of sawdust as absorbent that reduces the garbage filter output of fluid and acceleration garbage degradation, realizes the minimizing of percolate and quickens garbage degradation speed.
Summary of the invention
Technical scheme of the present invention is:
With the sawdust oven dry, the water content that makes sawdust is added to its even mixing in the house refuse after the cooling below 2%, and the volume ratio of sawdust and house refuse is 1:5～20, and then house refuse is carried out landfill.Owing to reasons such as rainfall and garbage decomposition, its rubbish internal moisture increases gradually behind the consumer waste filling and embedding, and sawdust can absorb the moisture of rubbish inside, up to reaching its saturation moisture content in a large number because characteristic such as porous, specific area be big.Afterwards, the sawdust after the suction begins degraded gradually, and the main component cellulose in the sawdust is degraded according to following approach:
Sawdust has consumed the moisture that absorbs in degradation process, its hydrogen that absorbs in the moisture enters methane, and oxygen enters carbon dioxide, does not have new moisture to produce, and has therefore realized the decrement of percolate.
The surface nature of the sawdust microbial adhesion that suits, thereby can be used as filler, when microorganism forms biomembrane attached to the sawdust surface in a large number, can quicken the degraded of rubbish.In addition, sawdust has stronger suction-operated to ammonia nitrogen, adds the stripping that sawdust can reduce the pollutant ammonia nitrogen in rubbish, reduces the ammonia nitrogen concentration of percolate.
Because sawdust is to the decrement effect of percolate, to the accelerated degradation effect of rubbish, to the suction-operated of ammonia nitrogen, mixing the interpolation sawdust in rubbish can make the percolate generation of every liter of rubbish reduce 1000～1400 milliliters, in garbage loading embeading 0.47 meter of sedimentation after more than 40 day, reduce percolate ammonia nitrogen concentration 500～2000 mg/litre.
Good effect of the present invention is:
1, only need in proportion sawdust evenly to be mixed to add in the landfill waste, operation is simple;
2, sawdust have be easy to get, cheap characteristics, so the cost of this method is lower;
3, sawdust is given full play to its powerful water absorbing properties in rubbish, and the moisture of absorption can be consumed by sawdust, and sawdust can not produce new moisture in degradation process, thereby has realized the decrement of percolate.
4, the biomembrane of sawdust surface formation can quicken garbage degradation, and sawdust is added on the effect that can bring into play the absorption ammonia nitrogen in the rubbish.
The specific embodiment
1, sawdust dries
The fresh poplar sawdust of choosing is put into baking oven, dry by the fire 2h down at 100 ℃ then, remove contained moisture in the sawdust;
2, sawdust adds
According to the ratio of sawdust volume/rubbish volume=1/15, sawdust evenly is mixed in the house refuse of landfill, then with garbage loading embeading, the earthing compacting.
3, continue to add
When continuing landfill waste on landfill waste layer, still the ratio by sawdust volume/rubbish volume=1/15 continues the adding sawdust.
Claims (2)
1, the method for sawdust decrement percolate and acceleration garbage degradation is characterized in that the sawdust landfill after house refuse is evenly mixed that will dry.
2,, it is characterized in that the sawdust of drying and the volume ratio of house refuse are 1:5～20 according to the sawdust decrement percolate of claim 1 with quicken the method for garbage degradation.
