The utility model discloses a rapid reaction precipitation sewage treatment system, which is characterized in that sewage is firstly subjected to denitrification reaction with nitrification liquid containing a large amount of activated sludge to remove nitrate nitrogen, then enters an aerobic reaction zone, is oxidized by heterotrophic aerobic bacteria in an aerobic nitrification environment, finally enters a rapid precipitation reactor, and is subjected to sludge-water separation in the zone. The reactor is reasonable in structural design, and has the following beneficial effects that (1) the traditional process is broken through in spatial arrangement, and the reactor is organically combined in the same reaction system in a combined construction manner, so that the overall occupied area is greatly reduced; (2) a unique pool body structure is adopted, so that the carbon removal and nitrogen removal efficiency of the system is high, low-power circulation is realized, and the operation cost is reduced; (3) the
