人工湿地生态修复旅游景区污染水体的研究

Purification of polluted pond water of a tourist attraction by integrated wetland and plant treatment

提出了采用人工湿地并配合植物操控技术治理旅游景区污染水体,并建立了示范工程。经调试运行,在日处理水量为145 m3条件下,人工湿地对TN、TP、COD和BOD5的去除率分别为63.12%、40.47%、83.07%和73.45%。工程通过2个月的运行,污染水体的水质得到明显改善。该技术为旅游景区和景点的污水治理提供了新途径。

The paper presented the results of treating slightly polluted pond water of a Zheiiang tourist attraction in a constructed wetland full of plant growth. The integrated wetland and plant treatment removed major portions of total nitrogen,total phosphorus,COD and BOD5 constituents of the inflow （145 m^3/d） with removal rates of 63. 12%, 40. 47%, 83.07% and 73.45%, respectively. After two-month operation of the integrated wetland and plant treatment system,the water quality was improved significantly. The integrated phyto-wetland system is cost effective for treatment of polluted water in tourist sites.
