Biogas fermenting
|
Tech Description: Biogas fermenting technology can transform the organic of biomass to biogas.
Tech Index:
• The air pressure reaches 800ml mercury column
• Normal using life should longer than 15-50 years
• The biogas fermenting production accords with relevant criterion. |
| 2.
Desulfurization
|
 Tech Description: The biogas produced by factories contains large number of hydrogen sulfide, which not only pollutes the environment but also erodes the equipment, so the desulfurizing technology and installation is needed to separate and remove the hydrogen sulfide efficiently
Tech Index:
• The content of hydrogen sulfide after desulfurizing is less than 0.1%
• Under the ordinary temperature , the saturated sulfur content of the desulfurization chemical ¡Ý50%
• The equipment runs steadily
|
| 3.
Technology of CHP
|
 Tech Description: In order to comprehensive use the biogas producing by factories, it is need the CHP technology and equipment to transfer the biogas to electric energy and heat energy
Tech Index:
• The electrical energy transformation rate is ¡Ý30%
• The heat energy transformation rate is ¡Ý40%
• The normal using life should longer than 15 years |
| 4.
Technology of producing organic fertilizer
|
 Tech Description : In order to comprehensively use the biogas residue brought from the process of biogas production, it is necessary to produce the organic fertilizer utilizing biogas residue as the raw material and adding other dosages as auxiliary
Tech Index:
• The production accord with current Europe relevant criterion
• The content of water (free water) is ¡Ü20%
• PH value be kept around 6-8 |
| 5.
Technology of artificial wetland sewage treatment
|
 Tech Description: The technology of artificial wetland sewage treatment is to remove the organic, nitrogen and phosphor in the sewage of the small-sized breeding farms, avoiding pollute the water bodies and the earth
Tech Index:
• The sewage discharged after treatment is accord with the relevant standard
