Problems solved by technology

[0003] However, the nitrogen and phosphorus interception devices currently on the market only absorb nitrogen and phosphorus nutrients in the water by planting water plants inside the interception device. The intercepting device is connected in pieces during use, and it is difficult to replace the cultivation sleeve, which affects the interception efficiency of the aquatic plants inside the cultivation sleeve, and cannot intercept the solid pollutants floating in the river surface, thereby increasing the flow rate of the river water. degree of pollution

Embodiment 1

[0026] Such as Figure 1 to Figure 6 The nitrogen and phosphorus interception device for a pastoral landscape type ecological ditch shown includes an interception floating plate 1; there are placement grooves 21 on both sides of the interception floating plate 1, and a cultivation sleeve 6 is inserted in the placement groove 21, and the side of the cultivation sleeve 6 There is a clamping structure matching the side support plate 8, and the side support plate 8 is fixed on the interception floating plate 1 and is located below the placement groove 21; the middle part of the interception floating plate 1 is vertically provided with a lifting structure.

Embodiment 2

[0028] Based on Embodiment 1, and the clamping structure is that the cultivation sleeve 6 is provided with an adapter pole 36, the outer ring of the adapter pole 36 is fitted with a ring-shaped adapter sleeve 37, and the side surface of the adapter sleeve 37 is There is a strip-shaped limiting clamping plate 38 , a through-hole groove 35 on the side support plate 8 matches the adapter sleeve 37 , and a clamping groove 39 on the side of the through-hole groove 35 matches the limiting clamping plate 38 .

Embodiment 3

[0030] Based on Embodiment 1, and the intercepting floating plate 1 has a floating plate 10 on the top, the floating plate 10 is installed in the socket frame 9, and the socket frame 9 is fixed on the intercepting floating plate 1 .

Abstract

The invention provides a nitrogen and phosphorus intercepting device for a field landscape-type ecological ditch. The nitrogen and phosphorus intercepting device comprises an intercepting floating plate; placing grooves are formed in two sides of the intercepting floating plate, cultivating sleeves are inserted into the placing grooves, clamping structures are arranged on side faces of the cultivating sleeves and matched with side supporting plates, and the side supporting plates are fixed to the intercepting floating plate and located below the placing grooves; and a lifting structure is vertically arranged in a middle part of the intercepting floating plate. The cultivating sleeve can be rapidly and conveniently replaced, nitrogen and phosphorus pollutants in a landscape river can be fully intercepted, meanwhile, management personnel in the landscape river can conveniently clean the landscape river, and thus the landscape river surface is kept clean and pollution is reduced.

Description

technical field [0001] The invention relates to a nitrogen and phosphorus intercepting device for a pastoral landscape type ecological ditch, which belongs to the pollution control technology. Background technique [0002] The ecological ditch technology is similar to the currently widely used constructed wetland wastewater treatment technology. The nitrogen and phosphorus nutrients in the farmland drainage in the ditch are absorbed, absorbed, precipitated, filtered, and microbially degraded under the joint action of ditch aquatic plants and ditch sediment microorganisms. The roots of aquatic plants can directly absorb ammonia nitrogen, nitrate nitrogen and phosphate in farmland drainage, and promote their exchange at the interface by breaking the interface balance, thereby accelerating the rate of pollutants entering the sediment and enhancing its retention capacity. [0003] However, the nitrogen and phosphorus intercepting devices currently on the market only absorb nitr...
