Abstract

Abstract

The existence of a large number of polymers in polymer flooding oil production wastewater affects the properties of the sewage, and its pollution mechanism for ultrafiltration membranes is different from that of the general oil production wastewater. In this paper, the influence of polymer concentration on membrane flux in the process of simulating polymer-containing wastewater in ultrafiltration filtration was studied. The chemical cleaning scheme was optimized through chemical cleaning of the membrane fibers contaminated by the actual raw water and scanning electron microscope analysis of the contaminated membrane surface and section. On this basis, the preferred chemical cleaning scheme was used to clean the membrane modules in engineering applications. The research results showed that as the polymer concentration increased, the membrane flux attenuation gradually increased; the combination of sodium hydroxide and sodium dodecylbenzene sulfonate had the best cleaning effect on polymer pollution, which restored 75% of the initial flux; scanning electron microscopy showed that substances in the raw water would accumulate on the membrane surface to form a stable gel layer and cause irreversible pollution to the membrane.
