[0002] This integrated device for paddy field drainage regulation and pollutant interception is suitable for the intelligent transformation of drainage systems in rice-growing areas and the ecological treatment of farmland runoff. It can realize multiple functions such as automatic regulation of drainage flow, interception of straw impurities, and removal of nitrogen and phosphorus pollutants. It is widely used in high-standard farmland construction, ecological ditch renovation and agricultural non-point source pollution control projects.

[0003] Insufficient automation in paddy field drainage control: Traditional paddy field drainage relies on manual opening and closing of gates or fixed elevation overflow outlets, which cannot dynamically adjust the drainage volume according to real-time rainfall, farmland water level and water quality indicators. Low efficiency in treating pollutants from farmland runoff: Incomplete interception of straw and other impurities: Existing drainage ditches generally use fixed grids with high porosity, which are insufficient for intercepting straw fragments and can easily lead to blockage of subsequent treatment units; Limited nitrogen and phosphorus removal efficiency: Conventional wetland systems often use single fillers whose adsorption capacity cannot meet the discharge requirements of paddy field liquids; Weak water quality buffering capacity: The pH of farmland runoff fluctuates greatly due to the effects of fertilization and pesticides. Traditional treatment systems lack effective buffering mechanisms, which can easily lead to a decrease in microbial activity and unstable nitrogen and phosphorus removal efficiency. The purification effect is low, especially under strongly acidic or alkaline conditions.

[0020] The filter assembly 2 includes a wetland pool 21, modified zeolite 22, steel slag particles 23, and straw biochar 24. The wetland pool 21 is installed on the main body 1 of the field ridge.

[0021] An installation groove adapted to the wetland pond 21 is provided on the surface of the main body 1 of the field ridge. The wetland pond 21 is directly connected to the installation groove by plugging and unplugging, which is convenient for later replacement. On both sides of the surface of the wetland pond 21, installation slots adapted to the T-shaped pipe 3 and the drainage pipe 10 are respectively provided to facilitate the flow of water.

[0022] Modified zeolite 22, steel slag granules 23, and straw biochar 24 are used for nitrogen and phosphorus removal and pH buffering in farmland drainage, thus purifying water quality. At the same time, modified zeolite 22, steel slag granules 23, and straw biochar 24 are all adsorption fillers.

[0026] The lifting device 6 includes a motor 61, a threaded rod 62, a threaded sleeve 63, a connecting bracket 64, and a baffle 65. The motor 61 is installed on one side of the wetland pool 21.

[0029] The wetland pool 21 is equipped with a cover plate 8.

[0030] The working principle of the integrated device for paddy field drainage and pollution interception provided by this utility model is as follows: In use, when draining water from the field during the flood season, the motor 61 is first started to drive the threaded rod 62 to rotate. When the threaded rod 62 rotates, it drives the threaded sleeve 63 on the surface to move. When the threaded sleeve 63 moves, it drives the telescopic pipe 5 to adjust inside the T-shaped pipe 3 through the connecting bracket 64. When the telescopic pipe 5 is adjusted to be flush with the water surface, the motor 61 is stopped. Then the water in the field flows through the grid 7 into the inside of the grid 7. Then the water flows through the telescopic pipe 5 and the T-shaped pipe 3 into the inside of the wetland pond 21. When the water flows into the inside of the wetland pond 21, it is filtered through the modified zeolite 22, steel slag particles 23 and straw biochar 24 inside.
