A Type of Rainwater Ecological Treatment Technology: Rainwater Biofiltration System

This paper introduced a kind of rainwater biofiltration processing technology being researched and applied in Australia. It summarized FAWB researchers’ major research and progress on the system configuration, packaging selection, plant selection and purification effect of this technology. And the advantages were presented in removing the suspended matters, heavy metal ions and nutritional pollutants in rainwater biofiltration system, as well as in regarding to the characteristics of effectively stored the rainwater for recycling in system configuration. The paper also put forward suggestions to the technical improvement for our country’s rainwater treatment system and structure design for reference.
