Phosphorus diffusion control device for farmland irrigation canal
The invention discloses a phosphorus diffusion control device for a farmland irrigation canal, which comprises a precast concrete outer frame arranged in the irrigation canal, the top of the precast concrete outer frame is higher than the bottom of the irrigation canal, a stainless steel gabion is arranged in the precast concrete outer frame, and the stainless steel gabion is filled with iron ore filler. And an opening and closing type top cover is arranged at the top of the stainless steel gabion. Phosphorus in water is adsorbed by iron ore, so that the method is suitable for reducing the amount of surplus phosphorus entering a water body after farmland irrigation, reducing the content of phosphorus discharged into a water body environment and reducing the load of the water body, and is beneficial to keeping the stability of the water quality of surrounding water bodies for a long time; the device is modularized, small in size and basically free of maintenance in the later period, only regular cleaning is needed, filler replacement can be operated by a single person, the replaced filler adsorbs phosphorus and can be used as a phosphate fertilizer, and the resource utilization degree is high.
本发明公开了一种用于农田灌溉渠的控制磷扩散的装置，包括设置于灌溉渠渠道内的预制混凝土外框，所述预制混凝土外框的顶部高于灌溉渠渠底，所述预制混凝土外框内设有不锈钢石笼，所述不锈钢石笼内填充有铁矿石填料，所述不锈钢石笼的顶部设有开合式顶盖。本发明利用铁矿石吸附水中的磷，适用于削减农田灌溉后富余磷元素进入水体的量，降低排入水体环境的磷含量，减轻水体的负荷，有利于长效保持周边水体水质的稳定；模块化构成，装置体积小，后期基本无维护，只需要定期清理，填料更换可单人操作，更换下来的填料已吸附磷元素，可作为磷肥使用，资源化利用程度高。
