垂直流迷宫工艺(VFL)在北方村镇污水处理厂的设计与应用

Design&Application of Vertical Flow Labyrinth Process(VFL)in Sewage Treatment Plants in Northern Villages&Towns

针对我国北方农村生活污水水质特征,介绍一种垂直流迷宫工艺(VFL)新技术,并结合农村污水排放的特点,有针对性地提出了分散式污水处理系统和集中式污水处理系统。该工艺抗冲击负荷能力强、投资及运营成本低、设备易于管理,在我国北方农村甚至高寒和生态环境敏感等典型地区都具有较为广泛的应用前景。

In view of the characteristics of rural domestic sewage quality in northern China,a new vertical labyrinth process(VFL)technology is introduced,and combined with the characteristics of rural sewage discharge,a decentralized sewage treatment system&a centralized sewage treatment system are proposed.The process has strong impact load resistance,low investment and operation costs&easy equipment management.It has a relatively broad application prospect in rural areas in northern China,even in typical areas such as high cold&sensitive ecological environment.
