Composite treatment process of household water purifier

Abstract

The invention discloses a composite treatment process of a household water purifier. The process comprises the following steps: step 1, adsorption via active carbon; step 2, oxidation via ozone, wherein ozone can oxidize a plurality of organic matters and remove chroma and stink in water, does not fully oxidize organic pollutants in drinking water, changes the structures and morphologies of organic matters, reduces the toxicity of the organic matters, improves the adsorptivity of the organic matters on active carbon and enhances the biodegradability of the organic matters to promote biochemical effect; step 3, membrane separation; and step 4, water softening, mineralization and magnetization. According to the composite treatment process of the household water purifier, a plurality of purifying methods are adopted for combined purification, so the purification process of a system can be completed, output purified water taste sweeter, and good softening mineralization and magnetization effects are exerted on water.

Description

technical field [0001] The invention relates to a water purification method, in particular to a composite treatment process for a household water purifier, and belongs to the technical field of water purification. Background technique [0002] Water pollution not only aggravates the shortage of water resources, but the deterioration of water quality seriously threatens the physical and mental health of the people; therefore, it needs to be purified according to the characteristics of water pollution. The methods used to remove or reduce organic pollutants in source water include: chemical oxidation, mainly ozone oxidation, hydrogen peroxide oxidation, potassium permanganate oxidation, photocatalytic oxidation and their combined processes, etc.; physical adsorption method , including granular activated carbon adsorption (GAC) and powdered activated carbon adsorption (PAC), etc.; biological oxidation methods, such as biological contact oxidation, aerobic biological filter, bio...
