Abstract
Reclaimed water has become an important source for non-potable reuse in urban area of many countries. As the water is usually reclaimed from domestic wastewater, it inevitably contains residual pollutants associated health and ecological hazards. In this talk, attention is paid to the removal of organic micropollutants and the reduction of their ecotoxicities for water reuse for environmental purposes. It firstly deals with pollutants in reclaimed water and associated hazards, and then introduces the methods for safety evaluation of the reclaimed water quality, bio-toxic characteristics of residual organic substances and their removal by advanced treatments, and organic micropollutants removal and biotoxicity reduction by ecological processes. It is finally concluded that ecological safety of water reuse can be ensured by setting engineering and ecological barriers.
