Novel ecological ditch for agricultural non-point source pollution treatment
The invention relates to the field of agricultural non-point source pollution treatment, and provides a novel ecological ditch for agricultural non-point source pollution treatment. The ecological ditch is used for solving the problem of agricultural non-point source pollution. The provided novel ecological ditch for agricultural non-point source pollution treatment comprises an impermeable layermade of impermeable geo-textile; a biological ceramic filter material layer, which is connected with the impermeable layer; a modified fly ash layer, which is connected with the biological ceramic filter material layer; and an ecological permeable dam, which adopts a gabion box filled with a biological ceramic filter material and is arranged at the side part of the ecological ditch; wherein hydroponic commercial crops are planted on the modified fly ash layer. Pollutants such as nitrogen and phosphorus in agricultural non-point source pollution are effectively intercepted, and the agriculturalnon-point source pollution is effectively controlled.
本发明涉及农业面源污染治理领域，提供一种用于农业面源污染处理的新型生态沟渠，用于解决农业面源污染问题。本发明提供的一种用于农业面源污染处理的新型生态沟渠，包括：防渗层，所述防渗层采用防渗土工布；生物陶瓷滤料层，所述生物陶瓷滤料层同所述防渗层连接；改性粉煤灰层，所述改性粉煤灰层同所述生物陶瓷滤料层连接；生态透水坝，所述生态透水坝采用石笼网，所述石笼网内填充生物陶瓷滤料，所述生态透水坝设置在生态沟渠的侧部；所述改性粉煤灰层上种植有水培经济作物。有效地截留了农业面源污染中的氮磷等污染物，有效地控制了农业面源污染。
