The invention discloses a double-channel water feeding composite circulating flow constructed wetland and an operation method thereof. The double-channel water feeding composite circulating flow constructed wetland comprises a water inlet regulating tank, a vertical flow constructed wetland, a water storage circulating tank and a photovoltaic reoxygenation backflow device. By combining an enhancedpretreatment method and an intermittent operation method, the continuous operation of the constructed wetland is realized while the blockage of the constructed wetland is relieved and the nitrogen and phosphorus removal effect is improved, the operation efficiency of the constructed wetland is effectively improved, meanwhile, the maintenance is simple, a large amount of manpower and material resources are not consumed, namely, the blockage problem of the constructed wetland can be effectively solved. 本发明公开了一种双通道进水的复合循环流人工湿地及其运行方法，它包括进水调节池、垂直流人工湿地、储水循环池、光伏复氧回流装置。本发明通过将强化预处理和间歇运行这两种处理方法联合，在缓解人工湿地堵塞、提升氮磷去除效果的同时，实现了人工湿地的
