Bismuth Tungstate--Dyeing Wastewater Treatment with Acrylic Composite Fiber
Dye pollution is one of the most important environmental pollution sources in the world. Dye wastewater has the characteristics of complex composition, high chromaticity, large amount of emission, toxicity and biochemical degradation. It has been a difficult problem in wastewater treatment. In recent years, with the development of photocatalytic technology, more and more photocatalysts have been developed. Bismuth tungstate has been widely used for its excellent photocatalytic degradation ability, there is no doubt that bismuth tungstate has better degradation effect on dye wastewater. However, in recent years, it has been found that bismuth tungstate is good, but it is easy to assemble, difficult to separate and difficult to recover. In order to solve this problem, some scholars have proposed a scheme for making composite materials of bismuth tungstate and acrylic fiber. Acrylic fiber is also called polyacrylonitrile fiber, also known as synthetic wool, and bismuth tungst...
