Abstract
Ultrafiltration has high separation efficiency, process equipment is simple, the operation management convenient, no phase change and energy saving, etc in wastewater reuse with characteristic, is widely used. In recent years, many new achievements of ultrafiltration technology(UFT)have been obtained in the fields of production of drinking water, and wastewater purification and reuse, and the technology showed a promising application foreground. This paper makes a brief ultrafiltration technology, and the description of ultrafiltration in wastewater treatment several areas on the various application forms were analyzed and discussed. Also face with your own reading a corresponding summary, expressed the ultrafiltration development of future expectations. The research status of the ultrafiltration technology applied in the production of drinking water, and in the treatment of oil-containing wastewater, fiber and paper industry wastewater and some other kind of wastewater were summarized, meanwhile, the application the developing tendency of the said technology treating the corresponding wastewater was pointed out.
