Gasification system and wastewater treatment method

A gasification system according to one embodiment of the present invention is provided with: a scrubber device for transferring contaminants contained in a combustible gas to wash water and discharging the wash water containing the contaminants as scrubber wastewater; a heat exchange device that vaporizes contaminants contained in the scrubber wastewater by heating the scrubber wastewater; and a combustion furnace that incinerates the gasified contaminants, and the heat exchange device heats the scrubber wastewater using heat generated by the combustion furnace. 一方式的气化系统具备：洗涤器装置，其将可燃性气体所含的污染物质转移至清洗水，并且将包含污染物质的清洗水作为洗涤器废水排出；热交换装置，其通过加热洗涤器废水而使洗涤器废水所含的污染物质气化；以及燃烧炉，其对气化后的污染物质进行焚烧，热交换装置利用由燃烧炉产生的热对洗涤器废水进行加热。
