Comprehensive treatment system based on farmland recession
The invention discloses a comprehensive treatment system based on farmland recession, and the system comprises an intercepting and settling tank which is arranged below a farmland and is used for intercepting, standing and settling the farmland recession; the recession water conveying system is arranged above the intercepting sedimentation tank and used for conveying farmland recession water to the farmland for secondary irrigation or conveying the farmland recession water to the ditch filtering system for filtering and discharging; the ditch filtering system is used for filtering farmland recession water; and the pit-pond filtering system is used for purifying and discharging the farmland recession water. According to the comprehensive treatment system based on farmland recession, the interception sedimentation tank is used for intercepting the farmland recession, the situation that the farmland recession is directly discharged into a river to pollute a river channel water body is avoided, a layered structural design is adopted for the ditch filtering system, the farmland recession needing to be discharged is filtered, and meanwhile it is guaranteed that water flow is smooth; the pit-pond filtering system is used for further removing pollutants such as phosphorus and nitrogen from the farmland recession water, so that the deep purification efficiency of the farmland recession water is improved.
本发明公开了一种基于农田退水的综合处理系统，包括截流沉降池，设置在农田的下方，用于截流以及静置沉降农田退水；退水输送系统，设置于截流沉降池上方，用于将农田退水输送至农田进行二次灌溉或输送至沟渠过滤系统进行过滤排放；沟渠过滤系统，用于对农田退水进行过滤；以及坑塘过滤系统，用于对农田退水进行净化排放。本发明提供的一种基于农田退水的综合处理系统，利用截留沉降池进行农田退水的截流，避免农田退水直排入河对河道水体造成污染，沟渠过滤系统采用分层的结构设计，对需要排放的农田退水进行过滤，同时保证水流的畅通；坑塘过滤系统对农田退水进一步进行磷氮等污染物的去除，提升了农田退水深度净化的净化效率。
