[0017] 2、Through the setting of the sewage treatment desliming mechanism, when the sewage filtered through the metal gauze screen is used, the sewage is first blocked by the buffer plate and then overflowed into the sedimentation bin, so that the flocculent and floating matter carried in the sewage is deposited to a certain extent, and then the flocculent is filtered out by the cleaning liquid pump, and the mud suction pump is started regularly to suck the sludge from the sedimentation bin and the mud collecting groove, so as to reduce the accumulation of sludge.
