Ecological resource recycling system and method based on farmland irrigation and drainage system
The invention discloses an ecological resource recycling system and method based on a farmland irrigation and drainage system. The system comprises a farmland, a water diversion main stream, a drainage branch stream, a drainage ditch and an irrigation and drainage canal system. In a dry season and a flat water period, water replenishing and drainage are performed on an irrigated area from an adjacent water diversion main stream, a certain ecological flow is injected, and in an irrigation and drainage period, water enters a farmland by utilizing an irrigation canal system, and redundant drained water passes through a drainage canal system and passes through a step-by-step interception and purification facility to reduce initial pollution load and then is converged into a drainage ditch; pollutants in a drainage ditch are reduced by adopting an advanced treatment technology, then the water enters a drainage branch, and the branch is used for regulating and storing redundant drained waterlogging water and then returns to a diversion main stream again. According to the method, existing irrigation and drainage systems and rules of farmland are combined, surrounding water systems are fully utilized, an ecological resource comprehensive utilization system is built, an accurate operation scheduling scheme is formulated, an agricultural non-point source pollution control system and treatment capacity are effectively promoted, and efficient utilization of agricultural water resources is enhanced.
本发明公开了一种基于农田灌排体系的生态资源化循环利用系统及方法，该系统包括农田，引水干流，排水支流，排水河沟和灌排渠系。在枯水期和平水期，从临近的引水干流对灌区进行补水引流，注入一定的生态流量，灌溉排涝期，利用灌溉渠系进入农田，多余的沥水通过排水渠系经逐级拦截净化设施降低初期污染负荷后汇入排水河沟中，在排水河沟中采用深度处理技术削减污染物后进入排水支流，利用支流调蓄多余的沥水涝水后重新回到引水干流。本发明结合农田现有的灌排体系和规则，充分利用周边水系，建设生态资源化综合利用系统，制定精准的运行调度方案，有效推进农业面源污染控制体系和治理能力，加强农业水资源高效利用。
