WASTE WATER TREATMENT EQUIPMENT BY COMBINATION OF ANAEROBIC FLUIDIZED BED AND AEROBIC BIOFILM CONTACTING MEANS

摘要

The present invention is characterized by treating livestock wastewater generated in a livestock farm, by treating the anaerobic fluidized bed wastewater treatment means and aerobic biofilm contact means in combination, the main object of the present invention requires almost no operator's hand, a narrow site It is to provide a device that can be efficiently processed in. Specific configuration for this purpose is anaerobic fluidized bed reaction means consisting of anaerobic fluidized bed reactor, waste water is supplied through the first tank screen, secondary screen and flow control tank, and the necessary heat is supplied through the drying incinerator and heat exchanger, The wastewater is supplied from the anaerobic flow reactor, but the top height is installed at the bottom height of the anaerobic flow reactor, and the aerobic microorganism is retained therein, but is filled with a carrier having a specific surface area capable of sufficiently attaching and growing. It consists of aerobic biofilm contact means consisting of aerobic biofilm contactor which receives air from the blower to discharge the supernatant water from the settling tank through the disinfection tank, and the sludge is incinerated after reprocessing.
