Petroleum refinery wastewater (PRW) contains high concentrations of phenolic compounds and ammonia that are noxious and harmful to the environment, especially to human health. The improper treatment of PRW could cause serious problems. In this study, a membrane with a polyvinyl alcohol (PVA) coating was fabricated to improve PRW treatment for phenolic compounds and ammonia removal. The fabricated membranes were investigated using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), water contact angle, mechanical strength, permeability, pollutant rejection, and foulant resistance. The coated membranes exhibited improved surface properties and mechanical strength compared to that of uncoated pristine polysulfone (PSf) membranes. The membranes also showed excellent phenol and ammonia removal up to 82.68 % and 92.42 %, respectively. Although the permeate flux decreased with increasing PVA concentration, the antifouling behavior of the membrane was significantly improved. Therefore, the fabricated membranes showed great potential for petroleum wastewater treatment.

炼油厂废水（PRW）含有高浓度的酚类化合物和氨，对人体，尤其是环境有害，对人体有害。PRW处理不当可能会导致严重问题。在这项研究中，制造了具有聚乙烯醇（PVA）涂层的膜，以改善PRW处理酚类化合物和去除氨的能力。使用扫描电子显微镜（SEM），傅立叶变换红外光谱（FTIR），水接触角，机械强度，渗透性，污染物排阻和防污性研究了制成的膜。与未涂覆的原始聚砜（PSf）膜相比，涂覆的膜表现出改善的表面性能和机械强度。该膜还显示出优异的苯酚和氨气去除率，分别达到82.68％和92.42％，分别。尽管渗透通量随着PVA浓度的增加而降低，但膜的防污性能得到了显着改善。因此，制备的膜在石油废水处理中显示出巨大的潜力。
