Abstract

The invention provides an ultrafiltration and powdered activated carbon adsorption combined purification method for removing trace organic matters from drinking water. The method comprises the four steps of carrying out adsorption of an activated carbon adsorption reactor, carrying out activated carbon adsorption in an ultrafiltration membrane pool, carrying out ultrafiltration, and carrying out activated carbon refluxing. According to the method, the effect of removing the trace organic matters from outlet water is improved by increasing the concentration of activated carbon in the membrane pool, and the drive effect of the initial concentration on the activated carbon adsorption speed is fully utilized by refluxing the activated carbon to the activated carbon adsorption reactor; the combined purification method is simple in process, convenient to use, low in cost, good in purification effect and low in use cost, and basically does not need to be maintained.

Description

Technical field [0001] The invention belongs to the field of water treatment, and particularly relates to an ultrafiltration-powder activated carbon combined cleaning method for removing trace organic matter in drinking water. Background technique [0002] Organic pollution, especially the pollution of trace organic matter, is currently one of the problems that some cities in our country must face in drinking water sources. In addition to natural organic matter such as humic acid, organic pollutants also include endocrine disruptors and persistent organic pollutants (POPs). ), polycyclic aromatic hydrocarbons, polychlorinated biphenyls, algae metabolites, pharmaceuticals and personal care products (PPCPs), etc. Organic pollutants, especially trace organic pollutants, can seriously affect the safety of drinking water. Therefore, how to economically, efficiently and safely remove organic pollutants in raw water is a hot spot in the field of drinking water treatment. At present, th...
