Agricultural non-point source pollution treatment slope and construction method thereof
The invention relates to an agricultural non-point source pollution treatment side slope and a construction method thereof.The agricultural non-point source pollution treatment side slope comprises a side slope body and a farmland located at the top of the side slope body, the side slope body is sequentially provided with at least two filtering and purifying modules in the inclination direction of the slope surface, and each filtering and purifying module comprises a concrete layer arranged on the slope surface of the side slope body; farmland recession water is prevented from seeping into the lower layer; the pebble bed is located above the concrete layer and used for reducing soil loss; the soil layer is positioned above the pebble layer and is used for farmland recession adsorption and biodegradation; the vegetation retention layer is located above the soil layer and used for water and soil conservation and purification; the filter material filling layer is located on the same side of the pebble bed, the soil layer and the vegetation maintaining layer and used for adsorbing heavy metal in the farmland recession, and a filter material of the filter material filling layer is magnesium-loaded modified shaddock peel. By purifying the farmland recession water, the purpose of purifying the water quality is achieved, and the pollution risk is reduced.
本发明涉及一种农业面源污染治理边坡及其构建方法，包括边坡本体和位于边坡本体坡顶的农田，边坡本体沿坡面的倾斜方向上依次设置至少两个过滤净化模块，过滤净化模块包括：混凝土层，混凝土层设置在边坡本体的坡面上，用于防止农田退水渗入下层；卵石层，卵石层位于混凝土层的上方，用于降低土壤的流失；土层，土层位于卵石层的上方，用于农田退水吸附和生物降解；植被保持层，植被保持层位于土层的上方，用于水土保持和净化；滤料填充层，滤料填充层位于卵石层、土层和植被保持层的同一侧，用于吸附农田退水中的重金属，其中，滤料填充层的滤料为镁负载改性柚子皮。本发明通过对农田退水的净化，达到水质净化的目的，降低污染风险。
