| 摘 要： | 再生水回用是缓解城市缺水问题的有效途径.但当其回用于景观水体时,由于其污染本底高,景观水体滞缓流使得被补给水体水质难以保持,对此目前尚缺乏系统研究.选择天津空港物流加工区再生水景观水体,研究其水化学特征时序变化.结果表明:再生水景观水体的溶解氧含量与温度负相关;pH在4～6月为7.20～7.28,7～12月升为7.48～7.69,其变幅很可能是由沉水植物生长引起的;水生植物残体分解是维持水体冬季高锰酸盐指数(Im)保持在较高水平的主要原因;地表径流是景观水体中N、P和有机质的主要污染源.研究表明,为了保持再生水景观水体水质,必须有效控制降雨径流面源污染. |

| Abstract: | Reclaimed water reuse is an effective way to address the problem of water shortage in cities.When the reclaimed water is used to recharge the scenic water body,its heavily polluted background and its stagnant flow will make the aquatic quality difficult to remain satisfying,and till now the systematic research in this field is scary.The landscape water body in Tianjin Airport Industrial Park(TAIP)was chosen as a case study to investigate its sequential variation of chemistry characteristics.The result data ... |
