Traditional water treatment technology of environmental engineering can only precipitate the larger particles of impurities, or only remove the odor, but in fact some small particles will still exist in the water, which will bring some hidden dangers to people's water safety. Ultrafiltration membrane technology is a type of water treatment technology in which the solvent and small molecular weight solute in the solution can use the micropores on the membrane to enter the other side of the membrane, while some macromolecular solutes and harmful substances cannot enter the micropores and is blocked by the ultrafiltration membrane when the pressure is applied, and finally the raw water is purified; this technology not only can separate the particulate matter and the colloid, but also can separate the aquatic organisms and bacteria to a certain extent, and thus has been widely used in the fields of water treatment. On the basis of summarizing and analyzing the previous research results, this paper expounds the basic principles, functional characteristics, existing deficiencies and corresponding solutions of ultrafiltration membrane technology, and proposes an water treatment method and their applications of environmental engineering based on ultrafiltration membrane technology. The study results of this paper provide a reference for further research on water treatment methods of environmental engineering based on ultrafiltration membrane technology.
