摘要
灌溉已成为南方稻田土壤重金属Cd超标的主要输入源之一,研究通过构建"沉砂池+植物塘+人工湿地+吸附池"组合工艺系统,分析其对灌溉水中重金属镉(Cd)净化效果。结果表明,所选研究区域灌溉水中的Cd超标严重,根据GB 5084-1992灌溉水水质标准,该区灌溉水超标率高达82.69%,且水中可溶态Cd含量较高,平均为56.34%,潜在危害性大。经过工艺系统处理后水中可溶态Cd平均去除率为94.72%,全量镉(Cd)平均去除率为94.78%,贡献率主要集中在植物塘,对可溶态Cd和全量镉(Cd)的去除两个植物塘的贡献率总共占了70.92%和70.13%。可见,Cd超标灌溉水经过沉砂池+植物塘+人工湿地+吸附池组合工艺处理后可有效的去除灌溉水中镉,且系统依据地势采用无动力自流设计运行费用低,具有较强的推广潜力,可为Cd超标灌溉水的净化与稻田安全生产提供科学参考与数据支持。
Irrigation has become one of the main input sources of heavy metal Cd in paddy soils in southern China. The research on the purification of heavy metal cadmium(Cd) in irrigation water by constructing a combined process system of "grit chamber + plant pond + artificial wetland + adsorption pool". The results showed that the Cd in irrigation water exceeded the standard, according to the GB 5084-1992 irrigation water quality standard, the over-standard rate of irrigation water was 82.69%, and the content of soluble Cd in water was 56.34% Harmful. The average removal rate of soluble Cd was 94.72% and 94.78%, respectively, and the contribution rate of cadmium(Cd) was mainly concentrated in the plant pond, and the removal of Cd and Cd The total contribution of the two ponds accounted for 70.92% and 70.13%. It can be seen that the Cd over-standard irrigation water can effectively remove cadmium in irrigation water through the combination of grit chamber + plant pond + constructed wetland + adsorption pool, and the system is based on the terrain using non-power gravity flow design low operating costs, with strong promotion potential, Which can provide scientific reference and data support for the purification of Cd over-standard irrigation water and the safe production of paddy field.
