<p>PURPOSE: A method is provided, which is characterized in that wastewater is treated by filtration using porous organic materials, and it is composted. CONSTITUTION: A wastewater treatment device(1) comprises porous organic layer(40) which is made of sawdust and chaff adsorb organic materials of wastewater, and the surplus of wastewater flows through a mat layer(43) and a gravel layer(45) into a wastewater treatment zone(100), and an air layer(70) is formed. A composting zone(10) equipped with a conveyor(60) for sprinkling wastewater and mixing a porous layer compost porous organic material. A wastewater treatment zone(100) equipped with an air supplying device(300) is formed an aeration condition to treat wastewater by biomass.</p> |
