人工湿地技术应用于辽河下游污水处理的可行性研究

阐述人工湿地系统的概念及其用于污水处理中所具有的投资少、能耗低、效果好、易于管理等优点。对辽河下游重点河段进行了实地取样,测得氨氮、化学需氧量、浊度等严重超标;对该流域沿岸的土壤、地层做了调查,结果显示水土流失较严重,增加了农业面源对河流的污染。综合辽河下游水质及地貌的特征,提出了用人工湿地处理该流域的污水是可行的。

Feasibility study on constructed wetland system in treatment of sewage in the lower reaches of the Liaohe River

The article elaborated the concept of constructed wetlands system's and the advantage of treatment of sewage,low investment and low energy consumption,effective and easy to manage etc.Took a sample of the key section of the the lower reaches of the Liaohe River,the analysis show the ammonia nitrogen,COD,the turbidity etc.Serious exceeding the allowed figure;also to this basin coast's soil,the stratum has made the investigation.The result demonstration soil erosion is serious,increased the pollution of agricultural surface source to the river.Synthesizes the lower reaches of the Liaohe River water quality and the landform characteristic.Using constructed wetland system in treatment of sewage in the lower reaches of the Liaohe River is feasible.
