Embodiment
[0051] The direct drip irrigation system is arranged in Dengkou County, Inner Mongolia. The water source is Wushen Main Canal in Dengkou County. The annual average sediment concentration of this water source is 2.738kg / m 3 , the specific operation process of the drip irrigation system for directly diverting water from the Yellow River is as follows:
[0052] The Yellow River water first flows into the canal-slope water diversion system through the canal; the process is as follows: the Yellow River water enters the sump 3 of the canal slope filter, and the water level in the sump 3 continues to rise. After overflowing, it is filtered by a 200-mesh stainless steel filter 1, and large particles The sediment and floating objects are blocked outside the stainless steel filter, and the filtered water can flow into the catchment channel 2. At this time, the sediment content in the catchment channel is 2.464kg / m 3 , the irrigation water is driven by the suction pump 5 through the suct...

Abstract
The invention discloses a channel direct-diversion drip-irrigation system of irrigation districts along the Yellow River and a running method. The channel direct-diversion drip-irrigation system comprises a channel slope type water diversion system, a combined filter and a multifunctional drip line flushing pipe network. The channel slope type water diversion system comprises a channel slope filtering pool and an inclined pipe sand depositing pool. The channel slope filtering pool comprises a dirt collecting groove, a water collecting channel, a filter screen and a water suction culvert pipe.The inlet end of the water suction culvert pipe extends into the water collecting channel. The outlet end of the water suction culvert pipe is connected with the inlet end of a water diversion culvertpipe. The inclined pipe sand depositing pool comprises a water inlet pool and a clear water pool which are separated through a wall body. The outlet end of the water diversion culvert pipe extends into the water inlet pool. The combined filter comprises a sand-gravel filter and a lamination / filter screen filter. The clear water pool is sequentially connected with the sand-gravel filter and the lamination / filter screen filter through pipelines. The multifunctional drip line flushing pipe network comprises a drip irrigation drip line and a backflow pipeline. The lamination / filter screen filteris connected with the drip irrigation drip line through a pipeline. The drip irrigation drip line is connected with the backflow pipeline. The tail end of the backflow pipeline is connected with the sand-gravel filter or the water inlet pool of the inclined pipe sand depositing pool.
Description
technical field [0001] The invention relates to a high-sedinity water drip irrigation system and an operating method, in particular to a canal-direct drip irrigation system and an operating method in irrigation areas diverted from the Yellow River, and belongs to the technical field of agricultural high-efficiency water-saving irrigation. Background technique [0002] The Yellow River irrigation area is an important grain and cotton production base in my country, but the contradiction between supply and demand of water resources is extremely prominent. The water from the Yellow River, as an important source of water for irrigation areas diverted from the Yellow River, is under enormous pressure, and it is imperative to implement water-saving irrigation. As one of the most water-saving irrigation technologies at present, drip irrigation has the functions of efficient water use and precise irrigation. Compared with traditional irrigation methods, it has the advantages of savin...
