Embodiment Construction

[0011] The agricultural non-point source pollution ecological interception ditch of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0012] As shown in the figure, the agricultural non-point source pollution ecological interception ditch of the present invention comprises a ditch body with a rectangular cross-sectional shape, and a number of porous hollow bricks are respectively stacked on the two side walls 1 of the ditch body, and arranged on the bottom 2 of the ditch body There are concrete hollow bricks, a number of round holes 3 are set on the side wall 1, and a number of square holes 4 are set on the bottom 2. Economic aquatic plants that can absorb non-point source pollutants are planted in the round holes 3 and square holes 4 at the same time. The overflow dam 5 is set up in the section. The overflow dam 5 is piled up with concrete, soil, and pebbles. The side facing the ...

Abstract

The invention discloses an agricultural non-point source pollution ecological intercepting ditch, which comprises a ditch body with a rectangular section, wherein a plurality of porous hollow bricks are respectively piled up on two side walls of the ditch body, and concrete hollow bricks are distributed at the bottom of the ditch body; a plurality of round holes are formed in the side walls, and a plurality of square holes are formed in the bottom; economic aquatic plants which can absorb non-point source pollutants are planted in the round holes and the square holes at the same time; and overflow dams are sectionally arranged in the ditch body, and the economic aquatic plants which can absorb the non-point source pollutants are planted on the overflow dams. After the structure is adopted, water and soil loss can be prevented, the in-situ growth of the aquatic plants can be kept, and the plants are prevented from blocking a water channel due to extensively spreading to the surrounding for growth; nitrogen and phosphorus of surface runoff can be effectively intercepted, and suspended solids in the surface runoff can be effectively intercepted; and the original farmland drainage ditches are fully utilized. The project cost and maintenance cost are low, the operation and maintenance are simple, and the ecological intercepting ditch is convenient for large-area popularization and application.

Description

[0001] technical field [0002] The invention relates to an ecological ditch that integrates farmland drainage and interception of agricultural non-point source pollution, specifically an ecological interception ditch for agricultural non-point source pollution that is suitable for drainage and non-point source pollution control in mountainous and hilly areas and sloping agricultural areas The invention belongs to the technical field of farmland drainage and prevention and control of agricultural non-point source pollution. Background technique [0003] Agricultural non-point source pollution is the most important and widely distributed non-point source pollution. Nutrients such as nitrogen and phosphorus, pesticides and other organic or inorganic pollutants in agricultural production activities form surface and Environmental pollution of ground water. To control agricultural non-point source pollution, it is imminent to find advanced, practical and low-cost technologie...
