The invention discloses a phosphated slag harmless treatment system. The phosphated slag harmless treatment system comprises a reaction kettle, a main precipitation pool, a three-stage precipitation system, a centrifugal solid-liquid separator, a liquid storage tank, a flashing main machine, a hot air furnace, a first-stage cyclone separator, a second-stage cyclone separator, a cloth bag dust remover, a tail gas treatment system, multiple conveying pumps and a spiral charging device. The phosphated slag harmless treatment system is specially applied to phosphated slag harmless treatment, improves the phosphated slag utilization rate, reduces the influence on the environment by phosphated slag, improves the solid-liquid separation quality of the phosphated slag, and improves the solid-liquid separation efficiency of the phosphated slag; through arrangement of two stages of cyclone separators and the cloth bag dust remover, the separation rate of phosphated slag compounds and air after flashing evaporation is i
