▎ 摘　　要

NOVELTY - Preparing graphene hybrid bismuth tungstate microcrystalline glass fiber net comprises (1) subjecting bismuth tungstate microcrystalline glass powder and graphite powder, (2) uniformly mixing bismuth tungstate microcrystalline glass powder and graphene to obtain the graphene hybrid composition bismuth tungstate crystallized glass powder, (3) subjecting graphene hybrid bismuth tungstate glass-ceramic fiber using the graphene hybrid bismuth tungstate crystallized glass powder and (iv) subjecting graphene hybrid bismuth tungstate microcrystalline glass fiber by non-woven fabric technology to obtain graphene hybrid bismuth tungstate microcrystalline glass fiber net. USE - The net is useful for rectifying black and smelly water body of river stream (claimed). ADVANTAGE - The method is simple, does not need aeration oxygenation, saves energy, environmentally friendly and waste utilization.
