Embodiment Construction

[0025]A zeolite ditch system for recycling nitrogen and phosphorus in vegetable garden soil midflow, including: vegetable garden soil midflow and surface runoff storage ditch 1, zeolite diversion ditch 2, relatively impermeable layer 3, hand-operated water pump (attached figure 1 ,2). Described vegetable garden soil middle flow and surface runoff storage ditch 1 (attached figure 2 ): It is a part of the zeolite ditch system, it is used to store the middle flow and surface runoff of the vegetable garden, and it is a ditch formed by connecting multiple large-scale prefabricated concrete U-shaped grooves 6. In the large-scale prefabricated concrete U-shaped groove 6. The top 10cm in the middle of each section in the direction of the long axis is designed to collect surface runoff from the vegetable garden and horizontal flow in the soil. The seepage port 4 in the large-scale prefabricated concrete U-shaped groove 6; in the middle part of the large-scale prefabricated concrete U...

Abstract

The invention discloses a zeolite ditch system for recycling nitrogen and phosphorus in the vegetable garden soil subsurface flow. The zeolite ditch system is characterized in that both sides of the vegetable garden soil subsurface flow and direct surface runoff storage ditch (1) are communicated with two zeolite diversion ditches (2), a relatively water-impermeable layer (3) is arranged between two zeolite diversion ditches (2), and a water pump is located at the top of the vegetable garden soil subsurface flow and direct surface runoff storage ditch (1).

Description

technical field [0001] The invention relates to the technical field of agricultural non-point source pollution control, in particular to an ecological engineering and construction method for recycling nitrogen and phosphorus in the soil flow of vegetable gardens. Background technique [0002] Agricultural non-point source pollution refers to dissolved or solid pollutants in agricultural production activities, such as organic or inorganic substances such as soil particles, nitrogen, phosphorus, pesticides, rural livestock and poultry manure and domestic garbage in farmland, from non-specific Under the erosion of precipitation and runoff, a large amount of pollutants enter receiving water bodies such as rivers, lakes, reservoirs, bays, etc. through farmland surface runoff, soil midflow, farmland drainage and underground runoff, causing pollution. Agricultural non-point source pollution has the characteristics of dispersion, concealment, randomness, uncertainty, difficulty in m...
