| 摘 要： | 以二级水(常规生化处理)和自来水分别灌溉3种乔木和3种灌木,对比研究污水灌溉对绿地土壤环境的影响,结果表明污水灌溉与自来水相比土壤全氮、全磷、全盐含量均无显著差异。重金属(铬、镉、汞、铅、砷)含量无明显变化。二级处理水灌溉对土壤有机质含量和土壤细菌数量有增加的趋势,对土壤环境无明显的影响,但要加强长期灌溉的土壤盐分的监控,防避土壤盐分的积累。

| Abstract: | According to the investigation in Beixiaohe Effluent Treatment Plant,the impact of irrigation on green space ecosystem with reclaimed water was studied.The results showe that due to the long term irrigation,the soil and plants which irrigated with the secondary treated water were affected to some extent.The secondary treated water may have an impact on plants growth.Therefore,the effluent water which is used to irrigate green space should be improved the treatment level. |
