Abstract

The invention discloses a composite water purification filter element for a domestic water purifier, and belongs to the technical field of water purification. The composite water purification filter element includes a filter shell and a filter material layer; and the filter shell is used for holding the filter material layer, and the filter material layer includes a first mixture layer, a macroporous adsorption resin layer, a second mixture layer and an ultrafiltration membrane layer, wherein the first mixture layer, the macroporous adsorption resin layer, the second mixture layer and the ultrafiltration membrane layer are arranged in sequence from the top to the bottom. The composite water purification filter element provided by the invention has a long service cycle, can effectively purify water pollutants, guarantee the quality of effluent water, and meet drinking requirements; and meanwhile, the filter element has a good desorption effect, and can realize high-efficiency regeneration and reuse of the filter element and reduce costs of water purification.

Description

technical field [0001] The invention belongs to the technical field of water purification, and in particular relates to a composite water purification filter element for a household water purifier. Background technique [0002] At present, according to the World Health Organization survey, 80% of diseases and 50% of child deaths in the world are related to poor drinking water quality. According to data from the Ministry of Environmental Protection, groundwater pollution in half of my country's urban areas is seriously polluted, and 57% of groundwater monitoring points are not up to standard. In recent years, with the rapid increase of pollutant emissions, various organic pollutants and heavy metals have entered water bodies, polluting drinking water. However, 97% of drinking water plants in my country still use traditional coagulation, sedimentation, filtration and disinfection treatment processes, coupled with the obsolescence and aging of water supply facilities, resultin...
