METHOD FOR SIMULTANEOUSLY TREATING FELLED WOOD OR WASTE WOOD AND ALKALI WASTEWATER

摘要

PPROBLEM TO BE SOLVED: To provide a method for simultaneously treating carbon-containing felled wood or waste wood and alkali wastewater without discharging polluted water at all because carbon, which is contained in the felled wood or waste wood especially discharged by building construction or the like is immobilized by a small-scaled apparatus, and because the immobilized solid matter is easy to handle and the alkali wastewater is treated to be decomposed to neutralized water or water and solid matter such as calcium carbonate or the like. PSOLUTION: Biomass being the felled wood or waste wood made by absorbing and immobilizing carbon in the atmosphere is combusted to be gasified to perform the disposal treatment of the felled wood or waste wood, carbon dioxide is separated and recovered from the gas obtained by gasifying the biomass, and the recovered carbon dioxide and the alkali wastewater produced by building construction are subjected to gas-liquid contact treatment to perform the neutralizing treatment of the alkali wastewater to thereby separate the alkali wastewater into water and the solid matter.
