人工湿地处理三种典型工业废水的差异性分析研究

Difference Analysis of Constructed Wetland Treatment for Three Kinds of Typical Industrial Wastewater

讨论了人工湿地技术处理三种典型工业废水(含重金属废水、高耗氧量废水及含油废水)的区别,结合近年国内外的最新研究,通过分析比较,提出人工湿地技术处理不同工业废水时的几点建议:采取以垂直潜流为主的方式处理氨氮高含量废水;处理高耗氧量废水,填料起主要作用,沉积物考虑二次利用;处理含重金属废水,植物处于主导地位,特别注意植物收割和沉积物处理,并增加针对性措施等。为人工湿地技术在工业废水方面的应用提供参考。

The differences of constructed wetland was discussed in this paper,when they ware used to treat three kinds of typical industrial wastewater,with heavy metals,or with high oxygen consumption,or with oil. Based on the combination of previous comparative analysis and the most recent advances about constructed wetland,several suggestions were presented on constructed wetland. Treating wastewater with high ammonia nitrogen content,the subsurface flow constructed wetlandswas feasible. Treating wastewater with high oxygen consumption,the choice of packing in constructed wetlands was important,and reutilization of sediments accumulated at constructed wetlands bottom was considerate. Treating wastewater containing heavy metals,the choice of plants was dominant,and paying special attention to effective harvesting of plants and treatment of sediments,and strengthening application of targeted measures. This paper provides reference for the application of artificial wetland technology in industrial wastewater.
