Abstract
The invention discloses a method of removing volatile detrimental contents from the wastewater and the device; wherein, the method comprises the following steps: Guiding the gas into the wastewater stripping tower to form stripping gas which fully contacts with the wastewater in the stripping tower so that the volatile detrimental contents are brought out by airflow into discharge plasma reactor to be degraded under the discharge ion. The processed gas enters the stripping tower after recirculation to bring out the volatile detrimental contents and further degrades the volatile detrimental contents in the wastewater. Meanwhile, the water-soluble degraded products in the airflow are adsorbed. The method of removing volatile detrimental contents from the wastewater has the advantages of avoiding the effect on the environment imposed by the detrimental contents produced in the process of biochemical wastewater treatment, reducing the effects on the environment and enjoying high removing efficiency yet low operational cost. By combining the stripping tower and the discharge plasma reactor, the method in the invention has the advantages of simple operation, and applicability for popularization.
