以再生水回用途径为基础，结合天津市纪庄子再生水厂出水水质，构建出评价指标，并对景观用水、地表水的再生水分别进行了风险评价，得出再生水用于不同情况时的不同的环境风险，从而能更好的对再生水利用的环境风险进行评价。构建的城市再生水风险评价指标体系（包括健康风险指标和生态环境风险指标），为城市再生水回用及风险性评价提供了依据。

An evaluation index system was developed based on the reuse approaches and quality of reclaimed water from Jizhuangzi reclaimed wastewater treatment plant in Tianjin, and this index system can be used to performed the risk assessment of the reclaimed water from the landscape water and surface water. The environmental risks for the use of reclaimed water under different conditions were obtained, which can provide a better evaluation of the environmental risks of utilization of reclaimed water. The risk assessment index system of urban reclaimed water (including the health risk index and ecological environmental risk index) can provide references for the evaluation of reuse of urban reclaimed water.
