| titleOfInvention | Method for extracting arsenic and combustible gas from soil polluted by arsenic by using biotechnology |
| abstract | The invention relates to a method for extracting arsenic and combustible gas from soil polluted by arsenic by using biotechnology. According to the method, the soil polluted by the arsenic is used as a raw material. The extraction method comprises the following steps: breeding earthworms in the soil polluted by the arsenic and collecting the earthworms rich in arsenic by using a gasification device, a separation device, a gas filtration device and a gas storage tank, namely breeding the earthworms in the soil polluted by the arsenic and collecting the earthworms after four months, intensively airing and gasifying. When the gas flows through the filtration device, an arsenic compound attached to a filtration screen and a combustible gas are obtained; the solid is an arsenic-rich mixture; the earthworms are collected by using a water bath expelling method; the gas filtration device aims at filtering the arsenic to directly obtain an arsenic compound; when the arsenic compound is filtered out of the gas, a combustible gas rich in CO is obtained; and most of the earthworms are pheretima guillemis. The method for extracting arsenic and combustible gas from soil polluted by arsenic by using biotechnology has the beneficial effects that the arsenic in the soil polluted by the arsenic is gathered by the artificially bred earthworms; the secondary pollution to the soil in the overall process is avoided; the investment cost is low; and moreover, the decrease of the soil fertility caused by the damage to the soil structure can be avoided. |
