Abstract

The invention provides an electric control adsorption membrane assembly and a use method thereof. The electric control adsorption membrane assembly comprises an outer shell, a conductive layer is arranged on the inner wall of the outer shell; a water inlet and a reflux inlet are formed in the side wall of the outer shell; a purified water outlet is formed in the bottom of the outer shell; an electrifying unit is arranged at the top of the outer shell; a working unit is arranged in the outer shell; the working unit comprises a fixing device and an electric control adsorption device; the electric control adsorption device comprises an electric control adsorption film and a hollow supporting net; the electric control adsorption film is connected with the electrifying unit through an electric control adsorption film wire. Compared with an existing membrane assembly for a household water purifier, the electric control adsorption membrane assembly provided by the invention has the advantages that due to the adoption of the electric control adsorption membrane, trace organic pollutants in water can be effectively removed under low operation pressure, and an electric field can be directly applied to the membrane assembly so as to realize in-situ electrolytic adsorption, electric regeneration and electric cleaning of an inner membrane of the membrane assembly.

Description

technical field [0001] The invention belongs to the technical processing field of filters, and in particular relates to an electronically controlled adsorption membrane module and a use method thereof. Background technique [0002] There are a variety of organic substances in drinking water sources, such as natural organic matter (NOM), pharmaceuticals and personal care products (PPCPs) and trace pesticides, which cannot be completely removed during drinking water treatment. In addition, during the disinfection process of drinking water, the residual NOM in the water will react with the disinfectant and easily generate disinfection by-products such as methyl halide. [0003] Therefore, the trace organic matter remaining in the effluent of the water plant and the disinfection by-products produced during the disinfection process may all be detected in the tap water. It is worth noting that hydrophobic or semi-hydrophobic small molecule organic compounds such as persistent org...
