NOVELTY - The utility model belongs to agricultural sewage treatment field, specifically relates to an agricultural sewage treatment system based on graphene photo-catalysis technology, comprising a pre-processing tank, a permeable dam, a water quality lifting area and an ecological fish pond; the pre-processing tank is located in front of the permeable dam; the water quality lifting area is located behind the permeable dam; the ecological fish pond is located behind the water quality lifting area; the pre-processing tank is provided with a water inlet pipe connected with the livestock breeding area and farmland; an overflow dam is set between the ecological fish pond and the water quality improving area. The utility model solves the problem that the existing agricultural sewage treatment effect is not good, using the pre-processing tank, a permeable dam and a water quality improving area to realize the pollutant degradation in agricultural sewage, ensuring the water quality after the waste water treatment can be recycled and directly discharged.
