Traditional treatment methods including biological treatment and physicochemical treatment have problems such as low efficiency and high cost. Photocatalysis and membrane bioreactor (MBR) are currently popular technologies for treating organic pollutants, respectively utilizing photocatalysts and microorganisms to treat organic pollutants. Although photocatalysis and MBR have been widely applied in treating organic wastewater, they each have certain limitations. For instance, photocatalysis has problems with low selectivity, catalyst stability, and light pollution resistance, and 精品文档---下载后可任意编辑MBR has problems with membrane fouling. Therefore, a process that combines photocatalysis and M...
