NOVELTY - Night soil (human waste) recycling technique, comprises: river diversion method to flow the farmland runoff; biological absorbing and filtering method to re-absorb and utilize the nitrogen and phosphorus in the runoff with the plant species configured in the river diversion groove; accumulation and utilization method to collect the runoff which is absorbed and filtered and used as the irrigation water for further use as they contain nutrients; and solid waste recycling method to carryout harmless process to the farm solid waste as organic fertilizer in a recycling manner.    USE - The method is useful for controlling agricultural pollution to facilities (claimed).    ADVANTAGE - The farmland solid waste used as nutrient, which is used in the greenhouse plant to increase the recycling utilization ratio of the runoff water and nutrient in the agricultural facilities and effectively reduces the agriculture source pollution brought by the nitrogen and phosphorus pollutants in the farmland runoff and the solid waste. The farmland runoff is recycled, and the utilization ratio of the runoff water is increased (60-90%) and the loss of the nitrogen is reduced (20-30%) and the loss of the phosphorus is reduced (15-25%) and the recycling utilization ratio of the farm solid waste is increased to greater than or equal to 95%.    DETAILED DESCRIPTION - Night soil (human waste) recycling technique, comprises: river diversion method to flow the farmland runoff as per the designed closed circuit to prevent it from discharging in the environment; biological absorbing and filtering method to re-absorb and utilize the nitrogen and phosphorus in the runoff with the plant species configured in the river diversion channel; accumulation and utilization method to collect the runoff which is absorbed and filtered and used as the irrigation water for further use as they contain nutrients; and solid waste recycling method to carryout harmless process to the farm solid waste (vegetables, flowers and plants and straw) as organic fertilizer, which is used in a recycling manner.
