Abstract

The invention discloses a terraced rice field and ecological ditch organically combined agricultural non-point source pollution purification system. The system comprises a drainage ditch system, a soil ridge system, a collecting tank system, an aqueduct system and a paddy field marsh system, wherein the drainage ditch system is provided with a drainage ditch; the drainage ditch is provided with a diversion dam, a water inlet and a water outlet; the collecting tank system is provided with a first collecting tank, a second collecting tank and a third collecting tank; the aqueduct system is provided with a first aqueduct, a second aqueduct and a third aqueduct; the paddy field marsh system is provided with a first-level paddy field marsh, a second-level paddy field marsh and a third-level paddy field marsh. By arranging the three levels of paddy field marshes distributed stepwise to effectively filter sewage, the terraced rice field and ecological ditch organically combined agricultural non-point source pollution purification system provided by the invention effectively plays a role of the last defensive line for hindering non-point surface pollutants from entering the water bodies.

Description

technical field [0001] The invention belongs to the technical field of ecological management and relates to the purification of agricultural non-point source pollution in mountainous areas. Background technique [0002] The research and development of agricultural non-point source pollution control technology is the focus and difficulty of water pollution control at home and abroad. Ecological technologies are commonly used internationally to restore eutrophic water bodies, including seasonal wetland treatment systems, direct river purification technology, oxidation pond treatment systems, plant-soil treatment systems, aquatic plant treatment systems, etc., to restore the self-purification ability of water bodies, with low engineering cost , low energy consumption and operating costs, remarkable purification effect and so on. For example, the "Oxidation Pond Sewage Treatment" and "Natural River Design Technology" in Morro Heard, North Carolina, the United States, the biolog...
