Wastewater Treatment System and Wastewater Treatment Method Using Biologically Activated Charcoal

摘要

The wastewater treatment apparatus of the present invention is a contact rotary part containing vincho charcoal in a tank, a spraying part disposed on the contact rotating part and containing black coal, and a spraying part from the contact rotating part to the spraying part from the contacting part. A watering tube for sprinkling water into the watering spout, aquatic plant culture phase disposed between the contacting spout and the watering spout, and an air diffusion tube for introducing a malodorous gas. Small amounts of surfactants and colorants are adsorbed by vincho charcoal and black coal and degraded by microorganisms that grow on vincho charcoal and black coal. Microorganisms act to decompose odorous gases biologically.
