Efficient pretreatment system for cattle farm wastewater

The utility model relates to an efficient pretreatment system for cattle farm wastewater, which comprises a manure collection pool, a solid-liquid separation room, a transfer pool, an efficient pipeline mixer, a horizontal flow shallow air floatation pool and a clear water pool which are sequentially communicated through a water path, and a mechanical grating communicated with the manure collection pool is arranged in front of the manure collection pool. A roller solid-liquid separator, a stacked spiral sludge dewatering machine and an inclined screen solid-liquid separator which are sequentially communicated through a water path are arranged in the solid-liquid separation room, the inclined screen solid-liquid separator is communicated with a transfer pool through a water path, outlet water of the transfer pool passes through a flat plate ceramic membrane and then enters an efficient pipeline mixer, the efficient pipeline mixer is provided with a feed port for feeding PAC and PAM, and the feed port is commun
