In order to reach the water quality standard of water-saving irrigation and drip irrigation, the separation of raw water from sand, stones and suspended matters is required during use. The current common methods for performing solid-liquid separation on raw water include: natural sedimentation, sand filtration, screen filtration, and the like. The natural sedimentation is to introduce raw water into a water tank with a certain volume, under the condition that the water flows slowly, sand grains and other impurities in the raw water are sedimentated at the bottom of the water tank, so that the solid-liquid separation of the raw water is realized; the sand filtration is to use sand with a certain particle size as a filter medium, raw water passes through the sand as the filter medium, sand and other impurities in the water are intercepted on the surface of the sand as the filter medium or are adsorbed inside the sand, and the water after filtration passes through the sand as the filter medium and is sent to the next link, so that the solid-liquid separation of the raw water is realized; the screen type filtering realizes solid-liquid separation by taking a filter screen as a filtering medium, belongs to the known category and is not described. When natural sedimentation is adopted for various types of raw water, impurities such as sand stones with specific gravity greater than that of the water are precipitated at the bottom of the water tank, but organic organisms, algae and the like suspended in the water cannot be effectively removed, the impurities can influence the efficiency of agricultural water-saving irrigation, and the impurities are easy to block next-stage equipment. The sand filtration is performed through a pressure container or is comprehensively acted with a water tank in natural sedimentation, however, the adoption of the pressure container is limited by the capacity, the water treatment efficiency is low, the backwashing effect is poor, and frequent backwashing is needed; the sand filtration and natural sedimentation are also limited by the above limitations, and the description is not repeated; in addition, the sand serving as a filter medium has gaps among the sands, the surface area of the sand is increased, and organic matters in water are intercepted under the adsorption action to destroy organic matters required by agricultural water.
