摘　　要：随着生产生活的迅速发展,污水排放量也在逐年增多,生活污水及生产污水的处理一直是环境保护的痛点问题。如何平衡社会发展和污水处理排放之间的关系,并提出相应的解决办法是必须面对的问题。聚乙烯醇缩甲醛材料因其具有比表面积较大、价格低廉和稳定性好等特点,作为生物载体能够屏蔽不利的外部环境条件,为微生物提供良好的微环境,具有一定的应用前景。文章介绍了聚乙烯醇缩甲醛生物载体材料的制备及其处理污水的工艺,并展望了该处理工艺的发展方向。With the rapid development of production and life,as a by-product of sewage discharge is also increasing year by year,the treatment of domestic sewage and production sewage has always been a pain point of environmental protection,how to balance the development of soci-ety and the treatment and discharge of sewage and put forward corresponding solutions are the prob-lems we must face.Due to the characteristics of large specific surface area,low price and good sta-bility,polyvinyl formaldehyde material can shield unfavorable external environmental conditions and provide a good microenvironment for microorganisms as a biological carrier,and has certain application prospects.In this article,the preparation of polyvinyl formaldehyde materials and the treatment process of wastewater are introduced,and the development direction of the treatment pro-cess is prospected.
