Abstract
The invention discloses method for extracting arsenic and combustible gas from arsenic contaminated soil by biotechnology, which belongs to the category of biotechnology, novel material, novel energy resource, energy conservation and environment protection industry, low carbon and circular economies. The method comprises planting ciliate desert-grass or Pteris cretica that is capable of enriching arsenic in all arsenical contaminated soils and harvesting arsenic-enriched ciliate desert-grass or Pteris cretica finished grass. A grass cutting device, a gasifying device, a separating device, a purifying device, an arsenic removal air purifier and a gas storage tank are included. Compared with other methods to extract arsenic, the method for extracting arsenic and combustible gas from arsenic contaminated soil by biotechnology belongs to the category of biotechnology, novel material, novel energy resource, energy conservation and environment protection industry, and circular economy.
Description
Technical field
The present invention is directed to biotechnology and from As polluted soil, extract arsenic, combustible gas.Belong to biotechnology, new material, new forms of energy, energy-conserving and environment-protective, low-carbon economy, recycling economy field.
Technical background
Receive the soil of arsenic contamination and severe contamination, causing serious environmental to pollute and ploughing damage simultaneously, through water; Air, food gets into human body, and harm humans is healthy; How from last earth, getting rid of arsenic, recover the ecology of soil, is a difficult problem of world's pollution control.
Summary of the invention
Compare the method for extracting arsenic with other, from As polluted soil, extract the method for arsenic and combustible gas with biotechnology.Belong to biotechnology, new material, new forms of energy, energy-conserving and environment-protective industry, low-carbon economy, recycling economy category., in ciliate desert-grass or Da Ye rough brake herb, from ciliate desert-grass or Da Ye rough brake herb, extract arsenic enrichment from soil again and produce combustible gas simultaneously through plantation ciliate desert-grass or Da Ye rough brake herb with biotechnology to arsenic; Make the arsenic content in the soil be reduced to normal value, rehabilitating soil belongs to biotechnology; New material, new forms of energy, energy-conserving and environment-protective industry; Low-carbon economy, the recycling economy category.

The specific embodiment
Plantation ciliate desert-grass or Da Ye shaft mouth side grass-seed kind in the soil that arsenic content exceeds standard; Be enriched in arsenic in the grass with ciliate desert-grass or Da Ye rough brake herb, in enrichment gather in after ciliate desert-grass or the Da Ye rough brake herb growth and maturity of arsenic, cut into 2 to 3 centimetres; Be dried to moisture content and be lower than 10%; Gasify, the arsenic that is enriched in the grass becomes ash-deposition in gasification, obtain the arsenic product through separation and purification; The arsenic that contains in the fuel gas that gasification produces is regained after the arsenic removal clarifier absorbs, and the combustible gas after the purification is reproducible biomass energy.
Claims (3)
1. the method for using biotechnology from As polluted soil, to extract arsenic and combustible gas is to be raw material with As polluted soil, its production method comprise all in containing the contaminated soil of arsenic, plant can enrichment ciliate desert-grass or Da Ye rough brake herbs of arsenic, enrichment ciliate desert-grass or the harvesting that the Da Ye rough brake herb becomes grass of arsenic; Grass cut-out equipment; Equipment for gasification, separation equipment, purifier apparatus; The arsenic removal air purifier, gas tank.It is characterized in that: compare the method for extracting arsenic with other, from As polluted soil, extract the method for arsenic and combustible gas with biotechnology.Belong to biotechnology, new material, new forms of energy, energy-conserving and environment-protective industry, low-carbon economy, recycling economy category.
2. the method for from As polluted soil, extracting arsenic and combustible gas with biotechnology according to claim 1.It is characterized in that plantation ciliate desert-grass or Da Ye shaft mouth side grass-seed kind in being rich in the soil of arsenic; Through to enrichment the ciliate desert-grass or the Da Ye rough brake herb of arsenic gasify; Obtain rich arsenic solid mixture and contain the arsenic combustible gas; To rich arsenic solid mixture with contain the arsenic combustible gas and carry out the arsenic separation and purification, obtain the arsenic product.
3. the method for from As polluted soil, extracting arsenic and combustible gas with biotechnology according to claim 1 is when producing arsenic, and combustible gas has been produced.It is characterized in that so gas is when gasification ciliate desert-grass or Da Ye rough brake herb, to produce to contain the arsenic combustible gas, combustible gas obtains after the arsenic removal air purifier purifies.
