Abstract

The invention relates to a method for removing micro organic pollutants from tap water through Pluronic block copolymers. The Pluronic block copolymers are utilized to form large-sized micelles capable of being effectively separated by an ultrafiltration membrane, and the micelles are taken as carriers which are used for dissolving the micro organic pollutants in the tap water and then can be removed by ultrafiltration; meanwhile, the reversible conversion between monomer molecules and the micelles is controlled through simple temperature adjustment by a sensitive temperature effect of compound micellization to achieve regeneration recycling of the Pluronic block copolymers.

Description

technical field [0001] The invention belongs to the technical field of water pollution treatment, and relates to a Pluronic block copolymer used for removing trace organic pollutants in tap water. This removal method is suitable for further cleaning of tap water. If it is applied to residential quarters, it can realize the centralized supply of clean water in the quarters. Background technique [0002] In today's life and production, various washing products are used in large quantities, which has inevitably polluted the water source. At present, the general drinking water (tap water) disinfection process in the world only has chlorine gas treatment, which can effectively remove pathogenic bacteria, but cannot degrade organic pollutants. For organic pollutants, the introduced chlorine gas will instead combine (interact) with organic matter to form highly carcinogenic polychlorinated organic matter. [0003] The main methods used to remove organic pollutants in water bodie...
