Method of reducing farmland nitrogen and phosphorus emissions
The invention discloses a method of reducing farmland nitrogen and phosphorus emissions. The method comprises the following steps that (1) farmland runoffs are determined, and confluence nodes are highlighted; (2) the farmland runoffs are collected and subjected to primary treatment; (3) the farmland runoffs are subjected to purification treatment; (4) the farmland runoffs are subjected to storage adjustment and water purification; and (5) purified water is drained stably. The method of reducing the farmland nitrogen and phosphorus emissions is simple and convenient to implement, and low in operating cost; through modification on the conventional farmland channels and pools and new construction of a part of channels and pools, with the adoption of local water plants with purification functions in the channels and the pools, supplemented by appropriate engineering technological means, the method realizes the effects that agricultural non-point source pollutions, particularly nutritive elements such as nitrogen and phosphorus, are intercepted and removed, and the purposes of controlling the agricultural non-point source pollutions and improving the water environment quality are achieved finally.
