Embodiment Construction

[0017] like figure 1 , figure 2 As shown, the construction method of a ditch-like overflow ecological purification system of the present invention is as follows: first determine the construction area, select the gentle slope range where the terrain slope is ≤ 15% as the construction area; Excavate multiple parallel and spaced shallow ditches 1, where the excavation depth of the shallow ditches is 30cm, the slope ratio is ≤1:2, the excavation width is at least 1m, and the shallow ditches are filled with gravel 5 continuously or at intervals, with a particle size of 3 -8cm, the filling height is 20cm, to achieve more effective removal of pollutants, and moisture-resistant shrubs can be planted in the shallow ditch 4; in shallow use, the earthwork excavated in the shallow ditch is stacked on the low side of the shallow ditch 2, the soil ridge The width is at least 1m, the slope ratio is ≤1:2, and trees or shrubs are planted on the soil ridge 3. Among them, the herbaceous plant...

Abstract

The invention discloses a construction method of a furrow-shaped slow flow ecological purification system, belonging to the technical field of water pollution control and ecological repairing. The method comprises the following two steps of: determining a constructing region and constructing a furrow; selecting a slow slope range with the terrain slope which is less than or equal to 15% as the constructing region; digging a plurality of parallel interval shallow grooves (1) in a vertical direction of an inclined slope; continuously or discontinuously filling crushed stones (5) in the shallow grooves; planting humidity-proof shrub plants (4) in the shallow groove; stacking soil furrows (2) at one sides of the shallow grooves with the lower terrain; and planting arbor or shrub plants (3) on the soil furrows. The construction method has the advantages of simple construction method, easiness for operation, small engineering amount, little investment and strong operability; the construction method can be used as a process method of newly-established ecological repairing engineering and also can be used as a modified method on the basis of the existing repairing engineering; and the construction method has wide applicability, does not disturb the previous system and has a wide application prospect on the aspect of managing surface source pollution.

Description

(1) Technical field: [0001] The invention relates to a method for constructing a ridge-like diffuse flow ecological purification system, which belongs to the technical field of water pollution control and ecological restoration. (two) background technology: [0002] Ridges and furrows are a common method of land leveling in agricultural farming. The ridges are higher than the ground, and the furrows are used for drainage, irrigation, fertilization, etc., and are lower than the ground. Continuous furrows can form undulating ground. It is of certain value and significance to refer to the shape of ridges and ditches in the field of water pollution control and ecological restoration technology, especially for the purification of overflowing slopes, and ridges and ditches have a better effect on intercepting and purifying pollutants. [0003] Relevant studies have shown that the construction of a concave surface structure has significant environmental and ecological effects. It c...
