WASTEWATER TREATMENT METHOD AND EQUIPMENT USING A DUAL-DIFFUSION OXYGEN SUPPLY HORIZONTAL-FLOW BIOFILM

摘要

A wastewater disposal method using a two-way oxygen supply horizontal-flow biofilm includes a carrier that is formed of a permeable material so that oxygen is supplied to the biofilm from the bottom layer of the biofilm adjacent to the surface of the carrier, so as to achieve a mode of simultaneously supplying oxygen from the surface layer and the bottom layer of the biofilm. Wastewater disposal equipment using a two-way oxygen supply horizontal-flow biofilm includes a water intake system, a reaction system and a water discharge system.
