Wastewater treatment system using biologically activated charcoal and wastewater treatment method

摘要

A wastewater treatment apparatus of the present invention comprises: a contact rotation part in which a beech charcoal is contained in a tank; a sprinkling rotation part disposed on the contact rotation part and containing black coal; an air lpipe for pumping purpose water from the contact rotation part; A water spray tube for spraying the spray water into the water spray rotary part, an aquatic plant spray image arranged between the contact rotation part and the water spray rotation part, and an air diffusion tube for introducing the odor gas. Small amounts of surfactants and colorants are adsorbed by early-stage charcoal and black coal and decomposed by microorganisms grown in early-stage charcoal and black coal. Microorganisms act to biologically decompose odorous gases.
