An internal space of an integrated reaction pond body of the device is sequentially divided into anaerobic denitrification areas and aerobiotic nitrification areas, which are alternately distributed and serially connected with one another, along the running direction of the sewage, and an anaerobic denitrification area is arranged on the rearmost end of the reaction pond body; filler which is 80 to 90 percent of the volume of each anaerobic denitrification area is filled inside each anaerobic denitrification area, the upper part of each anaerobic denitrification area is provided with a gas collection pipe which is used for adjusting a self backflow state; and the bottom of each aerobic nitrification area is provided with a micro-pore aeration head, and a corresponding deflection plate is arranged above the rear side of the micro-pore aeration head. The nitrification areas and the denitrification areas are mutually independent from one another, the nitrified bacteria is intercepted in each nitrification area through a self-backflow way of the sludge, the denitrification efficiency is high and no alkaline is needed; and the domestic sewage non-backflow denitrification treatment device and method are suitable for the dispersion domestic sewage treatment, simple in process, convenient to manage, less in investment of capital construction, low in daily running expense and high-efficient in denitrification; and the sewage after being treated can reach a discharging standard A.
