Multi Media Upflow Filtering System for Nitrification, Denitrification and Suspended Solids Removal

摘要

The present invention relates to an upflow flotation wastewater treatment apparatus using a multilayer media, and more specifically, to form a media of different sizes in a multi-layer, and to raise the treatment waste and wastewater upwardly from the bottom thereof, and to filter and The present invention relates to a water treatment plant for nitrifying and denitrifying, comprising: a filter layer (T1) consisting of a wastewater inflow pipe (11), a back-air air diffuser (12a), a filter medium (13a) having a specific gravity and a large diameter, and an air diffuser. (12b), the median layer (T2) consisting of a median (13b) of medium specific gravity and diameter, the median layer (T3) and strainer (14) consisting of media (13c) of specific gravity and small diameter are sequentially installed In addition, the conveying pipe 16 is connected to the lower portion of the backwash air diffuser 12a while the treated water outlet pipe 15 is piped to one side of the upper portion thereof.
