The invention relates to the technical field of farmland non-point source pollution, and discloses a farmland non-point source pollution ecological soil purification bed which comprises a hard soil layer, wherein a sandy soil layer is fixedly installed at the top of the hard soil layer, a gravel purification layer is laid at the top of the sandy soil layer, a fertile soil planting layer is laid at the top of the gravel purification layer, two water storage pipelines are laid in the sandy soil layer, water seepage holes are formed in the tops of the water storage pipelines, permeable membranes are laid on the inner walls of the water storage pipelines, and ditch grooves are formed in the fertile soil planting layer. According to the farmland non-point source pollution ecological soil purification bed, filtered upper-layer water is discharged into the activated carbon filtering layer through the water outlet hole and is filtered again, and the filtered upper-layer water is discharged into the ditch groove through the water discharging pipe for storage, the sewage purification liquid medicine in the medicine storage box is pumped out by a draw-off pump and sprayed into the ditch groove through the spraying mechanism to be matched with a purification biological planting layer to purify the stored water again, so that the purification treatment and cyclic utilization of a water source in the planting area are ensured.
本发明涉及农田面源污染技术领域，且公开了一种农田面源污染生态土壤净化床，包括硬质土层，所述硬质土层的顶部固定安装有沙土层，所述沙土层的顶部铺设有砂石净化层，所述砂石净化层的顶部铺设有沃土种植层，所述沙土层内铺设有数量为两个的蓄水管道，所述蓄水管道的顶部开设有渗水孔，所述蓄水管道的内壁铺设有渗透膜，所述沃土种植层内开设有沟渠槽。该农田面源污染生态土壤净化床，过滤后的上层水通过出水孔排入活性炭过滤层内再次进行过滤经排水管排入沟渠槽内进行储存，进而保证了抽取泵将储药箱的污水净化药水抽出经喷洒机构喷洒至沟渠槽内配合净化生物种植层对储存的水进行再次净化，进而保证了种植区内水源的净化处理循环利用。
