Abstract
The present invention relates to a method and a device for controlling pollutants in basin water resources cycling utilization in agricultural activity areas. The method includes: providing an acidification tank, an aeration tank and a multi-media constructed wetland connected in sequence, which are 4˜10 m far from basin revetment, feeding basin water into the constructed wetland, adsorbing or degrading heavy metals and organic pollutants by the constructed wetland, and then transporting the treated basin water to the agricultural activity areas. The present invention effectively controls the content of heavy metals that will enter the agricultural activity areas, fundamentally reduces the content of heavy metals in the crops, promotes the growth of the crops, maintains sustainable and healthy development of agriculture, and therefore guarantees human health and safety.
