The agricultural water is ranked first in water used in various industries in China, but in the agricultural irrigation process, the sustainable development of local agriculture is directly restricted due to serious water shortage in partial areas and low water use efficiency. Drip irrigation is considered to be one of the most effective agricultural efficient water-saving irrigation technologies at present due to the characteristic of controllable precision. In the past, the government of China has paid great attention to the application of the drip irrigation technology to popularization, and a series of policy guidelines are given to support the development of the drip irrigation technology in agricultural irrigation, so that the development of the water-saving irrigation in China has come up with unprecedented development opportunities. With the shortage of water resources, poor quality water sources (such as reclaimed water, high-sand water, brackish water and the like) are increasingly applied as irrigation water sources, and drip irrigation with the poor quality water sources is increasingly attracting attention of a plurality of expert students. But the poor water source is rich in a large amount of particles, microorganisms, nutrients, organic pollutants and the like, and the particles and other components in the water can generate a series of micro-dynamic behaviors, so that the particles mainly exist in the form of microbial floccules, and a layer of biological film (polymer formed by solid particles, microorganisms, secreted viscous polymers and the like) is attached to the surface layer, so that an irrigation system is blocked. The problem of blocking of a drip irrigation system is always an international problem in the field of drip irrigation research, particularly in a drip irrigation system adopting an inferior water source with complex water quality, the problem of blocking of the system is more serious, the running risk of the drip irrigation system is increased sharply, and the service life of the drip irrigation system is shortened greatly.

A plurality of expert scholars mainly conduct a great deal of research on the aspects of hydraulic performance, filtering capacity, filter material selection, structural characteristics and the like of the sand filter, and a significant research result is obtained. However, the existing sand filter has the problems that water distribution is uneven, the filter material in the tank body is easy to generate hydraulic classification phenomenon, a filter cap at the bottom is easy to be blocked, backwash efficiency is low and the like when the sand filter is used, meanwhile, as the sand filter is of a closed structure and the large drip irrigation engineering sand filter is huge in volume, the device for comprehensively testing the water conservancy performance and the filtering capacity of the sand filter is not reported, and particularly, the test of the real-time change characteristics of the filter material in the tank body along with the system operation is not reported; meanwhile, no reasonable operation mode of the filter under the complex water quality condition of the yellow drainage drip irrigation system is reported at present.
