Rice field water-saving irrigation and tail water treatment system and method
The invention relates to a rice field water-saving irrigation and tail water treatment system and method.The rice field water-saving irrigation and tail water treatment system comprises a main canal, branch canals, branch canals, annular ditches, gates, water flow monitors and water pumps, the main canal communicates with the branch canals, the branch canals communicate with the branch canals arranged among multiple fields, and branch gates are arranged at the intersections of the branch canals and the branch canals; irrigation water enters the branch ditches from the main ditch and then flows into the branch ditches, circular ditches are arranged on the periphery of each field, inner gates are arranged at the junctions of the circular ditches, the irrigation water flows into the rice field along the circular ditches when the inner gates are opened, the branch ditches are communicated with middle ditches located in the middles of the fields, the middle ditches are communicated with drainage ditches, and drainage gates are arranged at the junctions of the middle ditches and the drainage ditches. Due to the fact that the height difference exists between the circular ditch and the middle channel, tail water in the circular ditch is discharged to the middle channel through a water pump, a drainage gate is closed, a tail water gate at the intersection of the middle channel and the diversion channel is opened, tail water in the middle channel returns to the diversion channel, and tail water treatment is achieved through rice while the tail water is recycled for water-saving irrigation. The treatment method and effect are the same.
本申请涉及一种稻田节水灌溉及尾水处理系统及方法，包括主渠、支渠、分水渠、环沟、闸门、水流量监测器和水泵，主渠连通着支渠，支渠和设置于多片田地之间的分水渠连通，支渠与分水渠的交汇处设置有分闸门，灌溉水从主渠进入支渠再流入分水渠，每块田地的四周均设置有环沟，环沟之间的交界处均设置有内闸门，打开内闸门，使灌溉水顺着环沟流入稻田，分水渠连通有位于每片田地中间的中渠，中渠连通有排水沟，二者连接处设置有排水闸，由于环沟与中渠之间有高度差，通过水泵将环沟中的尾水排至中渠，关闭排水闸，打开中渠与分水渠的交汇处的尾水闸，中渠尾水返回分水渠，循环利用尾水进行节水灌溉的同时，利用水稻实现尾水处理。处理方法，效果同上。
