摘要 介绍了人工湿地污水处理技术的净化机理,并以四川广元昭化镇的工程应用为实例,对该项技术在农村污水主要污染物的去除效果及运行的经济性进行了比较分析,结果表明,对于污水CODcr、氨氮、氮、磷的去除效率分别可以达到82.2%、65.7%、55.0%、94.0%。同时,一次投资费用和运行费用较小,其中每吨水的建设成本为976元,综合处理成本为0.35元。 The purification mechanism of constructed wetland wastewater treatment technology were introduced. Through the project examples implemented in Guangyuan city Sichuan province in west of China, the comparison was made between the removal effect of the main pollutant and running benefit while using this technology to treat the municipal sewage. The results showed that CODc, could be removed about 82.2%, NH3-N could be removed more than 65.7%, TN could be removed about 55.0%, TP could be removed about 94.0%. Meanwhile, the technology had the advantages of low investing and running cost, which construction cost was 976 yuan per ton and comprehensive treatment cost was 0.35 yuan per ton.
