Polder area water circulation rice field non-point source pollution treatment system
The invention provides a polder area water circulation rice field non-point source pollution treatment system which comprises a polder area. The polder area is composed of a polder embankment, a polder area gate station, an outside-polder river channel and an inside-polder river channel; the polder area gate station is arranged at the communication part of the outside-polder river channel and the inside-polder river channel; field parcels which are separated by ridges and are perpendicular to the inside-polder river channel are arranged in the polder area; and irrigation of crops in the field parcels is conducted by guiding water from the inside-polder river channel through an irrigation pump station and an irrigation pipeline, farmland recession water in the field parcels returns to the inside-polder river channel through ecological ditches, and therefore water circulation is formed. According to the polder area water circulation rice field non-point source pollution treatment system, the characteristics of the polder area can be fully utilized, a relatively closed water body environment is formed, and a water body in the polder area is recycled; by combining a digitally-controlled precise irrigation and drainage system and a green prevention and control system, water and nutrients can be recycled under daily working conditions, the irrigation water consumption, the chemical fertilizer consumption and the pesticide consumption of agricultural production are reduced, the non-point source pollution load is reduced, it is guaranteed that the farmland recession water is discharged to the outside-polder river channel in order under the rainstorm working condition, and the influence on the surface water environment is reduced.
本发明提供了一种圩区水循环稻田面源污染治理系统，包括圩区；所述圩区由圩堤、圩区闸站、圩外河道和圩内河道组成；圩外河道和圩内河道连通处有圩区闸站；在圩区内有由田埂隔断构成、方向垂直于圩内河道的田块；田块内农作物灌溉通过灌溉泵站和灌溉管道从圩内河道引水，田块内农田退水经由生态沟渠退至圩内河道，构成水循环。本发明能充分利用圩区特点，形成相对封闭的水体环境，在圩区内水体实现循环利用；结合数字化控制的精准灌排系统和绿色防控系统，日常工况下可循环利用水和养分，降低农业生产的灌溉用水量、化肥使用量和药物使用量，减少面源污染负荷，在暴雨工况保证农田退水有序排放到圩外河道，减少对地表水环境的影响。
