| 摘 要： | 再生水是农业灌溉的重要水资源。为了合理利用城市污水处理后的再生水资源,采用天津市纪庄子污水处理厂二级出水作为再生水,以自来水为对照进行叶类蔬菜小区种植试验,研究了再生水灌溉对菜地土壤次生盐渍化及盐分离子和重金属离子累积分布规律的影响。结果表明:除0~15 cm土层全盐量增加外,15~45 cm土壤层盐分累积现象与自来水灌溉相比无明显差异。与自来水灌溉相比,短期内采用再生水灌溉不会显著增加土壤阳离子含量。重金属在土壤中的累积也不明显,同时,不同再生水灌溉水量条件下,土壤中重金属含量无显著差异,且土壤中的重金属含量都远低于国家标准规定的允许值,表明再生水短期灌溉对土壤环境不会造成污染影响。

| Abstract: | Reclaimed wastewater is becoming one of the important water resources for irrigation,especially in arid and semi-arid areas.Experiments of irrigation with treated sewage effluent were conducted.During the period of experiments,tap water and secondary treated sewage effluent were used for irrigation,respectively.The experimental results showed that the total dissolved solid of 0 to 15 cm soil layer increased,the contents of soil cation were not obviously changed.The distribution on pattern of heavy metals in... |
