Uniform particle filter material water supply system

The invention relates to the technical field of water treatment, in particular to a water supply treatment structure capable of realizing high-efficiency and high-yield water filtration and rapid back-flushing cleaning, and particularly relates to a uniform-particle filter material water supply system which comprises a filtering device and a purified water collecting device, the filtering device is used for receiving an external water source to be filtered, the purified water collecting device is used for receiving water flow treated by the filtering device, a filtering water purifying assembly and a self-cleaning assembly are arranged in the filtering device, the self-cleaning assembly is used for cleaning the interior of the filtering device, and the purified water collecting device is also used for being connected with downstream water equipment or water treatment equipment. The whole system can quickly realize the quick backwashing of the filter material after the purified water is filtered, the backwashi
