A scattered duck breeding pollution control and recycling method comprises the steps of reducing nitrogen and phosphorus pollutant emission at a source, applying dry duck excrement after composting process to earthworm cultivation, settling duck excrement waste water after methane fermentation, discharging water after settlement to a reed field for purification, and arranging aquatic plants and animals in a duck water surface activity area for digesting and saving the nitrogen and phosphorus in the duck excrement to form an ecologic interception area. The invention can effectively control excrement discharge disorder in the scattered duck breeding, lower contamination to water, realize duck excrement recycling use, optimize breeding environment, and generate economic benefits. The method is simple to implement, and has low cost. strong applicability, and great popularization and demonstration significance.
