Abstract

The invention provides an intelligent water purifying system and an intelligent water purifying method. The intelligent water purifying system is utilized to automatically clean a first pretreatment unit to remove pollutants on the surface of a filter element in time. By introducing a detection device, the cleaning of the first pretreatment unit can be weakened or strengthened according to the detection result of the working condition of the first pretreatment unit and combined with intelligent cleaning program control, thereby effectively improving the cleaning effect of the filter element.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an intelligent water purification system and an intelligent water purification method. Background technique [0002] In the application process of the water purifier, PP cotton (polypropylene fiber made of artificial chemical fiber) filter element, activated carbon filter element, ultrafiltration membrane filter element, microfiltration membrane filter element, PAC (poly aluminum chloride, polymerized alumina) composite filter element, Membrane and carbon composite methods are used as pretreatment filter elements to remove impurities such as sediment, suspended solids, rust, colloids, bacteria, and large particles contained in tap water. In areas with poor water quality and high impurity content, the service life of the pretreatment filter element is short, resulting in frequent replacement of the filter element or affecting the performance of the water purifier, and the ...
