The invention discloses a permeable reactive filler for removing nitrate organisms from underground water, a system and a filling method thereof, and belongs to the field of underground water pollution remediation. The filler for the permeable reactive barrier system is formed by the mixture of biological slow release carbon source materials, pH buffer nutrient element materials and bacteria enrichment water treatment fillers, the process inlet and outlet areas of the permeable reactive barrier system are filled with water treatment filters, a process reaction area is filled with the mixture of quartz sand or basalt and fillers, and the bacteria enrichment water treatment fillers inoculated with acclimatized native denitrifying bacteria. According to the invention, slow release carbon source materials, slow release pH nutrient element materials and water treatment fillers can be flexibly added, and the shortcomings that the carbon source materials are inoculated with hang membrane materials and native microor
