Method for preventing sludge accumulation in sludge buffer tank

The invention discloses a method for preventing sludge accumulation in a sludge buffer tank, which comprises the following steps: on the basis of retaining a central stirrer of the original sludge buffer tank, annularly arranging an annular main pipe around the sludge buffer tank, communicating the annular main pipe with a DN50 aeration pipeline, and arranging an aeration valve on the DN50 aeration pipeline, the DN50 aeration pipeline is communicated with the annular main pipe through the aeration valve, aeration holes with the diameter of 3-5mm are formed in the annular main pipe every 0.3-0.7 m, the hole openings face downwards, the distance between the annular main pipe and the tank wall is 0.4-0.6 m, and the DN50 aeration pipeline is connected with compressed air with the pressure of 0.4-0.8 MPA. The invention aims to provide a method for preventing sludge accumulation in a sludge buffer tank so as to solve the problems of bottom sludge deposition, poor sludge circulation and reduction of the effective ca
