Abstract
The invention discloses an organic and inorganic composite methane biological oxidation matrix, which belongs to the technology field of reducing emission of greenhouse gases. The organic and inorganic composite methane biological oxidation matrix is formed by mixing an organic active material, an inorganic porosint and water at a proportion by volume. The proportion of the organic active material, the inorganic porosint and the water is 1: (0.1 to 10) : (0.1 to 10).
Description
Technical field
The present invention relates to the refuse landfill methane gas and reduce discharging the field, particularly relate to the compound methane biologic oxidation matrix of a kind of organic and inorganic.
Background technology
Along with methane (CH
4) greenhouse effects that produce of isothermal chamber gas discharging strengthen gradually to the mankind's threat, as cause more arid, flood and other harsh weather, and as world's second largest greenhouse gas emission state, the reduction of discharging pressure that China facing is huge.CH
4In about 12 years of life-span in atmosphere, its global warming potentiality (GWP) is CO
223 times, additional greenhouse effects contribution rate is 20%, reduces discharging CH
4The effect of getting instant result will be played.Methane source in the atmosphere mainly comprises: wetland, rice field, ruminant, refuse landfill, coal mining, natural gas leaking etc.Refuse landfill is CH
4Important mankind's activity source of release.Along with the quickening of urbanization process of China, the garbage disposal pattern just progressively changes into based on sanitary landfills from air storage, landfill yard CH
4Discharge capacity will rise year by year.It is the only carbon source and the energy that methane-oxidizing bacteria can utilize methane, is carbon dioxide and water with methane oxidation, thereby reduces greenhouse gas emission intensity, and this process is called methane biologic oxidation.Methane-oxidizing bacteria is in the natural existence of occurring in nature, particularly in the methane rich area, as refuse landfill top layer mulching soil.
Methane biologic oxidation must have the participation of oxygen just can finish.Oxygen in the soil aperture derives from the diffusion of air.Because soil particle is tiny, more weak and the bacterium consumption oxygen of diffusion that causes air, make that the activity and the scope of activities thereof of methane-oxidizing bacteria are limited greatly, methane-oxidizing bacteria mainly appears in the upper soll layer 50cm generally speaking, has restricted the positive role of methane biologic oxidation in reduction of greenhouse gas discharge.The patent (application number 200710079552.6) of the previous application of inventor is intended to improve the methane oxidation effect, but this method need additionally provide power supply oxygen, and certain operating cost is arranged by changing the supplying mode of oxygen.On the other hand, methane-oxidizing bacteria also needs certain nutriment could good growth, and nutriment is less in the soil, has also restricted the giving full play to of activity of methane-oxidizing bacteria.
Summary of the invention
The purpose of this invention is to provide the compound methane biologic oxidation matrix of a kind of organic and inorganic preparation method, to improve the matrix nutrient and the matrix pores of methane oxidation.
The compound methane biologic oxidation matrix of organic and inorganic provided by the present invention is to be formed by the blending in certain proportion of organic active material, inorganic porous material and water, and wherein the volume ratio between organic active material, inorganic porous material and the water is 1: (0.1～10): (0.1～10).
Described organic active material is generally, one or more in the material after compost treatment, the peat composed of rotten mosses, the peat.The raw material that wherein is used for compost treatment mainly comprises, mud, house refuse, food debris, plant residue, animal excrements.
The particle size distribution range of described organic active material is 0.1mm～100mm.The content of organic matter of described organic active material is 2%～95%.The moisture of described organic active material is 10%～80%.
Described inorganic porous material is generally, one or more in haydite, slag, slag, the sand.The raw material that wherein is used to make haydite mainly comprises clay, gangue, flyash, shale; The source of slag includes but not limited to, metal smelt, boiler combustion; The source of slag includes but not limited to mineral processing; The source of sand includes but not limited to, natural sand, artificial sand.
The particle size distribution range of described inorganic porous material is 1mm～100mm.The moisture of described inorganic porous material is 0.1%～50%.The porosity of described inorganic porous material is 10%～80%.
The present invention has significant beneficial effect:
(1) because the GWP of methane is 23 times of carbon dioxide, so the present invention has remarkable effect by being that carbon dioxide greatly reduces its global warming potentiality with methane conversion for cutting down the landfill yard greenhouse gas emission;
(2) inorganic porous material of the present invention can improve the gas permeability of matrix, reduces the resistance of Atmospheric Diffusion, thereby improves matrix oxygen supply ability;
(3) organic active material of the present invention can improve nutrient, the suitable moisture of maintenance of matrix and the abundant microbial population that comprises methane-oxidizing bacteria is provided, and makes methane-oxidizing bacteria strong in the adaptive capacity of occurring in nature;
(4) preparation method of the present invention is simple and easy to grasp, and does not need expensive instrument and equipment;
(5) the present invention does not need to provide extra power can realize the biological oxidation of landfill yard methane, helps alleviating landfill yard operation burden;
(6) material of the present invention is cheap and easy to get, has huge promotional value.
The specific embodiment
The present invention will be further described below in conjunction with embodiment, but embodiments of the present invention are not limited thereto.
Embodiment
It is the organic active material that present embodiment is selected the sludge composting thing, and the selection lytag is an inorganic porous material, and wherein the moisture of sludge composting thing is 30%, and the moisture of lytag is 5%.
(1) lytag and sludge composting thing are mixed with 1: 1 volume ratio;
(2) add water the moisture of mixture is adjusted into about 60%, and mix and be prepared into organic-inorganic composite ground mass;
(3) excavate original overlying soil on the landfill yard surface, replace organic-inorganic composite ground mass, its surface size is 5m * 5m;
(4) the landfill yard top layer overburden soil of choosing the next-door neighbour in contrast;
(5) the discharge of methane amount in monitoring organic-inorganic composite ground mass and next-door neighbour's the landfill yard top layer overburden soil.
The result shows that the discharge of methane speed of landfill yard top layer overburden soil is 100～300gm
-2Day
-1, the discharge of methane speed of organic-inorganic composite ground mass is 8～50gm
-2Day
-1As seen, compare with contrast, the methane oxidation ability of the organic-inorganic composite ground mass that constitutes with sludge composting thing and lytag significantly improves.
