摘　　要：针对深圳市3个污水处理厂再生水水体中的有毒有害化学物质,采用基于蒙特卡罗(Monte-Carlo)模拟的概率统计方法对再生水回用于城市绿化途径所造成的人体健康风险进行了定量评价。结果表明,深圳市A、B、C污水处理厂再生水中化学物质所致人体终身健康风险与个体健康风险均远小于国际公认可接受的最大风险水平,各污水厂的再生水可直接回用于城市绿化。Aimed at the toxic and harmful chemicals in reclaimed water of three sewage treatment plants in Shenzhen, the human health risk caused by reclaimed water used for urban greening reuse was evaluated quantitatively by probability statistics method based on the Monte -Carlo simulation. The results showed that the level of human lifelong health and individual health risks casued by chemicals in reclaimed water of A, B and C sewage treatment plants in Shenzhen was far less than the international recognized maximum accepted risk level and the reclaimed water could be directly back for the use of urban greening .
