【摘要】 采用PKA人工湿地技术,对浙江省某污染河道进行深度处理,通过湿地下游布水、上游排水至河道,强制性增强了河道的流动性。介绍了湿地设计参数,同时对工程造价、运营管理及运行成本进行分析。实际运行结果表明,该技术具有出水水质稳定、运行管理简单等优点,出水各指标均达到《地表水环境质量标准》（GB 3838—2002）Ⅳ类标准要求,对COD、NH₃-N、TP去除率分别为75.0%、67.2%、83.1%。更多还原

【Abstract】 PKA constructed wetland technology was applied in advanced treatment of a polluted river water in Zhejiang Province. The flow of water in the river was forcibly enhanced by distributing water downstream of the wetland and draining it upstream to the river.The wetland design parameters were introduced, and the project cost, operation management and operation cost were analyzed.The actual operation results showed that wetland technology had the advantages of stable effluent quality, simple operation and management, etc.The efluent met the class Ⅳ criteria specified in the Environmental Quality Standards for Surface Water（GB 3838-2002）,and the removal rate of COD, NH₃-N and TP were 75.0%, 67.2% and 83.1% respectively.更多还原
