Specific embodiment
The utility model is specifically described with reference to the accompanying drawing, it is as shown in Figs. 1-2, a kind of to utilize heavy Water fan and dirt
The MBR integration apparatus of denitrogenation dephosphorizing is realized in mud reflux, and including the conditioning tank 1 connecting with sewage network, the conditioning tank passes through
Elevator pump 2 is connect with the water inlet of anoxic zone 3, and the opening of the water outlet partition bottom end of the anoxic zone flows into aerobic zone 4, institute certainly
State aerobic zone water flow and film area 5 entered by advection, film area water outlet connects 16 water inlet of self priming pump by pipeline, it is described from
Sucking pump water outlet is by piping connection to final delivery pipe 6, and the sludge reflux pump 7 of film area front end is connect with anoxic zone, institute
It states aerobic zone and film area and is separately connected the air outlet aeration of heavy Water fan, the heavy Water fan is arranged on ground by ground 8
