Among the advanced oxidation processes, the photocatalytic process is a cost-effective, efficient, environmentally friendly and sustainable process for organic wastewater treatment. Along with the photocatalytic process, membrane technology can create an ideal combination in a hybrid technology, called membrane photocatalytic reactor (MPR), due to its high removal ability and low energy consumption. In the combined system, the photocatalytic degradation increases in the slurry state due to the greater contact surface of the photocatalyst and the effluent. Therefore, in this research, a slurry photocatalytic reactor for various bismuth-based photocatalysts was used in a combined system with the use of an ultrafiltration membrane, which was made by surface modification of the basic macrofiltration membranes made in the Research Institute of Petroleum Industry. The compounds based on bismuth, Bi2O3/WO3, Bi2O3@GO and NH2-MIL-125/Bi2WO6 were examined in order to eva‎luate the phases formed by various analyzes such as XRD, FTIR, ASAP, Raman, SEM and TEM, and the maximum yield was 62, 72 And 80% in oil decomposition and 68, 63 and 82% efficiency in phenol decomposition respectively. On the other hand, by combining Bi2O3/WO3 photocatalyst with ceramic membrane system in a slurry photocatalytic ceramic membrane reactor system under filtration conditions, applied pressure of 2 bar and flow rate of 44.1 cc/min, the overall efficiency of removing organic matter from phenol wastewater was 85.2% and for petroleum wastewater was 93.1%, which were measured by TOC and COD analysis, which show the total organic carbon and oxygen demand in feed and travide samples, respectively.
