DETAILED DESCRIPTION - System for preparing carbonized gas through waste resources comprises a carbonized gas collecting device, a biogas residue carbonizing device, a biogas residue treatment device and a biogas residue pond. The biogas residue pond is connected with the biogas residue treatment device, the biogas residue treatment device is connected with the biogas residue carbonizing device, the biogas residue carbonizing device is connected with the carbonized gas collecting device, and the biogas residue carbonizing device is powered through marsh gas power generation. In the biogas pool, the solid-liquid separation is carried out for collecting the raw biogas; in the biogas processor, removing the biogas residue from the biogas residue pool, adding the waste sawdust and waste paper carbonaceous cellulose, mixing and reducing the water content of the mixed biogas, and carrying out carbonization. In the biogas carbonization plant, the biogas with low water content is subjected to anaerobic mixing or anoxic reaction at high temperatures and pressures to produce carbonized gas; and in the carbonization gas collection means, collecting the separated carbonized gas, re-combusting into carbon monoxide, and using the carbon dioxide for plant photosynthesis.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the system for preparing carbonized gas through waste resources.
