The utility model discloses a solid-liquid separation nutrient collection device for rice and crab planting carbon nitrogen circulating water. The solid-liquid separation nutrient collection device mainly comprises a sampling assembly, a filtering assembly, a wearing assembly, a guide pipe and a sampling bottle. According to the equipment, water sample and mud sample extraction work is completed by controlling the power equipment, and the sampling efficiency is improved; the long-rod-shaped sampling assembly is held by a hand, and a worker can stand to complete sampling work; a worker does not need to squat beside the rice field for a long time in the sampling process; after entering the filter assembly, the extracted sample liquid is filtered and separated by the buffer tank, the first-stage filter tank and the second-stage filter tank, and the solid sample is mainly remained in the buffer tank; part of the flocculent sample remains in the primary filtering tank, and part of the flocculent sample is guided i
