天津开发区“双膜法”污水再生回用示范工程

Demonstration Project of Dual Membrane Process for Wastewater Reuse in Tianjin

对天津开发区污水回用项目进行了简要介绍。根据开发区污水水质特性 ,通过可行性研究论证并结合中试 ,确定了开发区污水集中回用采用连续流微滤与反渗透组合工艺 ;描述了工艺特点、工程建设情况以及对出水水质的分析比较 ;论述了在我国打破传统工艺 ,第一次大规模实施污水脱盐深度处理对于减少污染、开发水资源、分质回用、规范回用等方面促进区域经济可持续发展的重大意义。

The general status of wastewater reuse in the Tianjin economical developing area is presented briefly. On the basis of feasibility investigation and argumentation the combined continuous flow process of micro-filtration and reverse osmosis was adopted. In this paper the process feature and construction of this project are described, especially the quality of the outlet water and multi-purpose of renovated wastewater reuse. This is the first high capacity advanced wastewater desalination project in this country. It will be very profitable for pollution control, water resource development, also very helpful for the sustainable development in this area.
