Wastewater buffer system

The utility model relates to the technical field of wastewater treatment systems, in particular to a wastewater buffer system. The buffer system comprises a buffer tank (1) and a degradation device, wherein the buffer tank (1) comprises a tank body (2) for accommodating and temporarily storing wastewater; the degradation device is communicated with the tank body (2) and can provide degradation substances for the tank body (2), so that the wastewater in the tank body (2) can be degraded under the degradation action of the degradation substances, and further degraded water is obtained. The wastewater buffer system has dual functions of standing and temporary storage and wastewater degradation, and under abnormal working conditions, the tank body of the buffer tank can temporarily store wastewater and degrade the wastewater through degradation substances provided by the degradation device so as to obtain degraded water; degradation water discharged by the buffer system can meet the water quality requirement of t
