The invention discloses a pond foul water backflow discharge and ecological circulation system and method, and the system comprises at least one downstream pool which is arranged in a pond and is used for receiving foul water in the pond; the filtering blade window is arranged at the upper end of the side wall of the downstream pool and is used for filtering dirty water in the pool; the number of the water pouring channels is at least one, a water inlet of each water pouring channel is communicated with the downstream pool, a water outlet of each water pouring channel comprises at least one overflow channel and at least one drain opening, and the overflow channels and the drain openings are arranged on the periphery of the dam and / or the pond respectively and used for discharging / flowing dirty water. According to the pond foul water backflow discharging and ecological circulation system and method, self-discharging and self-circulation flowing of pond water are achieved through the pressure level difference, no power equipment or chemical agent input is needed, expenses can be greatly saved, power, energy and daily maintenance and management expenses can be reduced, and the system is suitable for large-scale popularization and application. The system has the advantages of low investment, quick effect, energy conservation, stable operation performance, simple daily maintenance and the like.
