摘要
阐述了复合垂直流构建湿地的设计理论基础及方法,分析其投资与运行管理费用,测试该系统对受污染水体的净化效果.中试系统表明对受污染地面水体中的化学需氧量(CODCr),五日生化需氧量(BOD5)和总悬浮固体(TSS)的去除率分别为66.1%,76.7%和72.4%.结合实际介绍了一个应用本系统处理受污染地表水的实例,实际工程对COD和BOD5的去除率分别为82.6%和85.8%.复合垂直流构建湿地投资低、运行费用省、维护简单、出水水质好,是一种实用有效的水处理技术,对水体水质改善和水生态系恢复具有重要意义.
The theory and design method of integrated vertical flow constructed wetland (IVCW) are explained; the investment and operation cost are analyzed and the purification efficiency of the system treating contaminated surface water is also demonstrated. The results of the pilot system show that the remove rates of chemical oxygen demand (COD\-\{Cr\}), five day's biochemical oxygen demand (BOD\-5) and total suspended solids (TSS) are 66.1%, 76.7% and 72.4% respectively. A full_scale system treating polluted surface water is introduced, it shows that the system can remove 82.6% COD and 85.8% BOD\-5. IVCW is a practical and effective wastewater treatment system with low investment and operation cost, it is easy to operate and maintain with high quality effluent so that can make significant contribution to the water quality improvement and rehabilitation of aquatic ecosystems.
